    Strong wind inhibits plant growth by creating mechanical stress and increasing water loss by increased transpiration. In the present study, we focused on far-red (FR) light as a factor that interacts with the effects of strong wind. We investigated the effect of wind speed (0.5 or 6.5 m s(-1)) on growth, photosynthate allocation, and stomatal conductance (g(s)) of cucumber (Cucumis sativus) seedlings under illumination with FR light (FR+) or without it (FR-). Interactions between wind speed and FR light influenced plant growth; strong wind decreased plant growth under FR+, but not under FR-. The growth decrease caused by strong wind resulted from decreases in the net assimilation rate (NAR) and leaf area ratio (LAR). The decreased LAR caused by strong wind was probably caused by decreased photosynthate allocation to the leaves as a result of the increased photosynthate allocation to the stem to resist the wind-created mechanical stress. The strong wind did not influence the photosynthate allocation under FR-, probably because the mechanical stress caused by the strong wind was smaller when stem elongation was decreased by FR-. The decrease in g(s) due to strong wind was smaller under FR- than under FR+. This may be a result of increased tolerance to water stress, which is associated with the increased proportion of active phytochrome under FR-, and may explain why the decrease in NAR due to the strong wind was smaller under FR-.

    Temporal and spatial variations in methane (CH4) emissions from the littoral zone of a shallow mid-latitude lake, Lake Suwa, were examined using the eddy covariance technique. The observation data were supplemented with dissolved CH4 measurement and incubation experiments of lake sediment and water. This lake had areas with steady bubble CH4 emissions, shaping the spatial variation in CH4 flux with strong spot emissions. In the other areas, CH4 was emitted via diffusion and episodic ebullition. CH4 emissions from this area had a clear seasonal variation, reflecting temperature variations, with a maximum monthly mean emission of 0.39 mu mol m(-2) s(-1) in August. The higher emission in summer was due to higher CH4 production in the sediment and the resulting higher dissolved CH4 concentration in the surface water. The steady bubble CH4 emission was seasonally controlled by the total hydrostatic pressure, with higher emission under lower pressure, suggesting regulation of the amount of bubbles emitted from the lake bottom by pressure. Isotope analysis revealed that this CH4 was produced biologically. This natural gas seepage was estimated to emit 1.9 Mg of CH4 annually. Compared with other eddy covariance studies over inland waters, CH4 emissions from Lake Suwa may be large for the latitude. This may be related to eutrophication, which enhances CH4 production.

    © 2020, Springer Nature B.V. In this study, wasabi plantlets were grown by photoautotrophic micropropagation under nine different day/night temperature regimes ranging from 10 °C/10 to 26 °C/26 °C. On day 28 of the culture, the dry weight and the leaf area were found to be highest under a constant air temperature of 18 °C/18 °C. Partitioning of plant biomass into stems increased whilst partitioning into leaves decreased with the increase in temperature. Whereas, partitioning of plant biomass into roots increased when the temperature increased from 10 to 18 °C but decreased with further increase in temperature to 26 °C. The shoot/root ratio showed an opposite trend compared with partitioning into roots, whereas the chlorophyll content of leaves increased when the temperature increased from 10 to 26 °C. The net photosynthetic rate of whole plantlets showed the same trend as plantlet biomass and was the highest in 18 °C/14 °C, 18 °C/18 °C, and 22 °C/18 °C treatments. By contrast, the value of the net photosynthetic rate per unit leaf area decreased sharply at temperatures ranging from 10 to 18 °C. A linear relationship between the net photosynthetic rate and RGR was clearly evident because of the large differences in the leaf area values. The specific leaf area of wasabi plantlets decreased slightly at temperatures ranging from 10 to 18 °C but increased substantially within the range of 18–26 °C; however, the leaf dry matter content showed an opposite trend. Low- and high-temperature ranges had contrasting effects on the leaf mass area and leaf nitrogen concentration. There was the high descent in dissolved oxygen concentration of culture medium at all treatments from day 0 to 7.

  • Far-red Light Interacts with Plant Density to Change Photosynthate Allocation of Cucumber Seedlings and Their Subsequent Early Growth after Transplanting

    The light competition in dense plant stands may be disadvantageous in transplant production because competition stimulates stem elongation and can reduce photosynthate allocation to leaves; this, in turn, may reduce the early growth rate after transplanting. In this study, we focused on how the proportion of far-red (FR) light affected light competition among cucumber (Cucumis sativus L.) seedlings and investigated the effects of the plant density X FR interaction on photosynthate allocation and subsequent early growth after transplanting. Seedlings at the cotyledon stage were planted into plug trays at densities ranging from 109 to 1736 plants/m(2); then they were grown for 4 days under light-emitting diode (LED) light containing FR light (FR+) at approximately the same red-to-FR ratio as in sunlight (1.2) or under light containing no FR (FR-). The higher density significantly stimulated stem elongation under both FR+ and FR-, but the effect was small under FR-; this indicates that light competition in the dense stands was inhibited by reducing FR light. The higher plant density significantly increased photosynthate allocation to the stem and decreased allocation to the leaves under both FR+ and FR-; however, again, the effect was smaller under FR-. After transplanting the seedlings to pots, early growth decreased in the seedlings that allocated less photosynthate to their leaves. Our results indicate that light with reduced FR can mitigate the disadvantageous photosynthate allocation of transplants and the reduction of early growth after transplanting that are likely to occur as a result of light competition at high plant density.

    © 2020, Springer Nature Switzerland AG. We investigated feeding and fecundity of the two-spotted spider mite, Tetranychus urticae (Acari: Tetranychidae), on leaves of cucumber (Cucumis sativus) seedlings that had been acclimatized to different light intensities. Based on these data, we analyzed the relationships between mite performance (feeding and fecundity) and leaf properties. The cucumber seedlings were grown in controlled-environment chambers under different light intensities at a photosynthetic photon flux density of 50, 100, 150, 300, or 450 µmol m− 2 s− 1 until the first true leaves had expanded. Adult females were released on the adaxial surfaces of excised leaf samples from the seedlings of each treatment group and held under standardized light intensity (200 µmol m− 2 s− 1). Fecundity and leaf damage area increased and decreased, respectively, as the acclimatization light intensity increased, indicating indirect effects of light intensity on feeding and fecundity through changes in the host leaf properties. Leaf mass per area (LMA) and photosynthetic capacity, which increased as the acclimatization light intensity increased, was positively related to the fecundity, but was negatively related to the leaf damage area. The higher LMA and photosynthetic capacity results in an increased amount of mesophyll per unit leaf area. This would allow the mites to feed efficiently from a limited area, which may explain the increased fecundity on these leaves.

    © 2019, Springer Nature B.V. The authors investigated whether biogas digestate could be used as a nutrient solution for rockwool culture. To do this, the authors examined growth performances of chrysanthemum cultured in rockwool and fed the filtrate of nitrified biogas digestate (f-NBD) derived from organic fraction of municipal solid waste and investigated whether application of the digestate caused nutrients to leach from the rockwool substrate. Plants that had been fed the f-NBD showed 33% lower fresh shoot weights and produced 35% fewer flowers than those that had been fed a commercial liquid fertilizer, whereas there were no significant differences in lengths of the shoots, chlorophyll contents of the leaves, numbers of days to first flowering, and maximum diameters of the flowers. Also, there were no significant differences in any of the growth parameters between plants that were cultured with the f-NBD supplemented with Mg and the commercial liquid fertilizer. These results indicate that the f-NBD could be used as a nutrient solution for chrysanthemum in rockwool culture if supplemented with Mg. In addition, a considerable amount of Fe was leached from the rockwool substrates following the application of the f-NBD, which could mitigate the expected Fe-deficiency symptoms in chrysanthemum.

    © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group. The goal of this study was to establish a system for co-culturing microalgae and crop plants with biogas digestate. We examined growth performances of E. gracilis and L. sativa co-cultured using a commercial liquid fertilizer designed for soilless culture supplemented with vitamins and ammonium. This solution simulated the filtrate of nitrified biogas digestate derived from the organic fraction of municipal solid waste but was supplemented with insufficient plant nutrients (Mg, Fe and Mn). The specific growth rate of the co-cultured E. gracilis was 0.761 ± 0.081 d−1 (mean ± SE), which was the same rate that E. gracilis achieved when grown as a sole culture. There were no significant differences between L. sativa cultured with E. gracilis until the stationary growth phase of E. gracilis was reached and those cultured alone relative to biomass, RGRs (relative growth rates), or relative to SPAD values of leaves. These results suggest that E. gracilis and L. sativa could be co-cultured with the biogas digestate after being nitrified and filtered. In addition, considering concentrations of plant macronutrients in the residual solution after the co-culturing E. gracilis and L. sativa, it could be re-used as the nutrient solution for co-culturing E. gracilis and L. sativa.

Photoautotrophic micropropagation (PA) in a sugar-free medium can facilitate acclimatization and increase success rates when transplanting tissue cultured plants to open fields. To identify savings in production costs (time and energy) during acclimatization in wasabi plants, we used in vitro PA with four kinds of supporting material (agar, perlite, rockwool, and vermiculite) and compared their effects on subsequent ex vitro growth (in vermiculite). The study revealed that, in all aspects, the plantlets in agar and vermiculite exhibited the highest growth, whereas plantlets in rockwool showed the worst growth performance. Growth performance in vitro seemed to be correlated with the volumetric water content of the supporting material. Agar and vermiculite promoted root growth and development with increases in number of roots, root length, and root fresh weight, and the root systems in these treatments also exhibited the best growth during the ex vitro stage. In culture vessels with plantlets, dissolved oxygen concentration (DO) in agar abruptly decreased from day 0 to day 7 but then recovered by day 28. DO decreased during the culture period very slightly, slightly, and steadily, with perlite, vermiculite, and rockwool, respectively. All the wasabi plantlets from the in vitro treatments survived after transplanting to the ex vitro condition, and subsequent growth was strongly influenced by the in vitro growth performance. Growth parameters of plantlets in the agar and vermiculite treatments were highest, whereas those in rockwool were lowest.

    © 2019 IOP Publishing Ltd. Glycerol is a major byproduct in the biodiesel manufacturing process which causes environmental problem since glycerol cannot be released without treatment. In this study, crude glycerol was refined into a pure form by using phosphoric acid. Esterification of the purified glycerol with oleic acid afforded glycerol monooleate in 43% yield using p-toluenesulfonic acid as a catalyst. The obtained glycerol monooleate was then allowed to react with lactic acid, acetic acid or diacetyl tartaric acid to provide the corresponding lactylated, acetylated or diacetyl tartarylated glycerol monooleate, respectively, in reasonable yields. These ester derivatives of monoglycerides have been known to be the most commonly used food surfactants.

    © 2019 Elsevier B.V. Plant responses to the red-to-far-red ratio (R:FR) of light have been investigated, but interaction between R:FR and other factors is less known. Here, we investigated the effects of R:FR × vapor-pressure deficit (VPD) on stem elongation and leaf expansion. Cucumber (Cucumis sativus) seedlings were grown in growth chambers at a VPD of 0.4 or 3.0 kPa, an air temperature of 28 °C, and an R:FR of 1.0 or 10 for 7 days after germination. Lower R:FR plus lower VPD synergistically stimulated stem elongation, likely owing to an interaction between cell-wall extensibility and turgor pressure, which (respectively) respond to changes in the proportion of active phytochrome and in evaporative demand. Leaf expansion was also stimulated at lower R:FR plus lower VPD, but unlike stem elongation, lower VPD reduced the effect of R:FR on leaf expansion. This may be explained by resource competition between stems and leaves: photosynthate allocation to leaves decreased under lower R:FR plus lower VPD. This may limit leaf expansion and thereby moderate the R:FR effect on leaf expansion, although additional factors may stimulate cell extension.

  • Development of an in vitro hydroponic culture system for wasabi nursery plant production—Effects of nutrient concentration and supporting material on plantlet growth

    © 2018 The growth of wasabi (Wasabia japonica Matsumura) plantlets was compared in four concentrations of standard Enshi nutrient solution (25%, 50%, 100%, and 150%) and two kinds of supporting materials (rockwool and vermiculite) using an in vitro hydroponic culture system for photoautotrophic micropropagation. After 28 days of culture, most of the growth parameters such as fresh weight and dry weight, shoot/root dry weight ratio, and leaf area ratio were highest in wasabi plantlets grown in 50% or 100% nutrient solution, and this enhancement was greater in vermiculite than in rockwool. Dissolved oxygen concentration decreased sharply in rockwool but only slightly in vermiculite during the course of the experiment, resulting in a dissolved oxygen concentration of 8 mg L−1 in the vermiculite and 6 mg L−1 in the rockwool. The highest root nitrogen concentration was observed at a nutrient concentration of 100% in vermiculite and rockwool. The highest net photosynthetic rates were observed on day 28 in vermiculite at nutrient concentrations of 50% and 100%. The growth of wasabi plantlets is depressed through a decrease in root water and nutrient uptake caused by low dissolved oxygen concentrations. These findings clearly demonstrate that a hydroponic system that incorporates a 50% or 100% nutrient solution concentration and vermiculite will allow high-quality wasabi plantlets to be propagated rapidly under photoautotrophic conditions.

    <p>     In order to easily and non-invasively grasp the reaction state of anaerobic digestion, which is one of the key-technologies concerning the resource recovery, spectra both fluorescence and reflectance of anaerobic digestion liquid (digestate) at different Fe concentrations were measured simultaneously. In the spectrofluorimetry, two kinds of fluorescent substances (aromatic protein-like substance and humus acid) as substrates derived from the methane fermentation reaction were observed. These emission intensities tended to increase with increasing Fe concentration, but decreased under maximum Fe concentration conditions. Spectral reflectance quantitatively showed the blackening of digestate with Fe addition. In the range from 500 to 1000 nm, Fe concentration and spectral reflectance showed a very high negative correlation (r > – 0.9). On the other hand, the iron concentration and redox potential of digestate showed a very high positive correlation (r > 0.9). Furthermore, the emission intensity derived from humus acid showed no linear relationship with Fe concentration. From these results, it was suggested that the black precipitate, which shows a decrease in spectral reflectance, is due to iron sulfide generation accompanied by consumption of reducing power.</p>
