The response of sago palm under water deficiency conditions was determined. Results showed that plants which watered at 7 days interval gave low leaf water potential which resulted in low water content in the roots and plants. There was not affected on the growth of sago palm as determined by plant height, leaf number, green value of leaf (SPAD), chlorophyll concentration, leaf dry weight and dry weight of whole plant. The concentration of nitrogen, phosphorus, potassium, calcium and magnesium in leaves of plants treated with water deficiency treatment did not differed in comparison to the plants treated with the normal water supply treatments.

Photosynthesis of sago palm (Metroxylon sagu rottb.) seedling at different air temperatures 国際共著国際誌

Photosynthetic activities of the sago palm (Metroxylon sagu Rottb.) were studied to find out its sensitivity to changes in ambient air temperature. The minimum ambient air temperature designed for the experiment was 25–29 °C, while the higher end was 29–33 °C. Several photosynthetic parameters were studied to support our analysis in sago photosynthetic activity, including diurnal leaf gas exchange, assimilation rate vs. CO2 concentration, leaf greenness, leaf chlorophyll content, and photosynthetic rate vs. irradiance. We found that sago palm photosynthetic activity tends to be more sensitive to minimum than to maximum ambient air temperature. The plants exposed to higher air temperatures had dark green leaf color associated with higher rates of diurnal photosynthesis, chlorophyll content, and rubisco limited photosynthetic activity. They also exhibited higher trend in optimum irradiance absorption level. Consequently, maximum light energy dissipation occurred at higher temperatures.

A rapid quantification method for leaf sodium (Na+) and potassium (K+) concentrations was developed using a compact ion meter. Leaf ion concentrations were evaluated for species of Vigna vexillata (L.) A. Rich. after two weeks of treatment with 0-200 mM of sodium chloride. To compare the ion extraction efficiency, extraction solutions of distilled water and ammonium acetate were tested. The ion concentrations of extracts obtained by both solutions were measured using an ion meter, and the values were validated using ion chromatography. For both extraction solutions, the ion meter values were highly correlated with those of the ion chromatograph. However, correlations between ion meter and chromatograph values were largely different for Na+ and K+. The rapid quantification of ion concentrations using an ion meter developed in this study was successfully utilized for evaluating differences in leaf Na+ concentrations, K+ concentrations, and K+/Na+ ratio in species of V. vexillata.

コムギの多収栽培技術の開発を目的に，耐倒伏性品種「さとのそら」を供試し，慣行の基肥重点型の施肥体系に対して，基肥を減らし追肥で窒素を増施用する生育後期重点施肥の効果を2カ年にわたって検証した．その結果，生育後期重点施肥により，茎立期以降の乾物成長量の大きくなる時期にLAIが高まったこと，登熟期後半まで葉色，NARが高く維持されたことでCGRが高く経過し，成熟期の総乾物重が大きくなった．一方で，茎立期の茎数が少なくなったことに加えて，この時期に窒素を増肥したことで，茎間の同化産物および窒素の競合が緩和され，茎の生存率が高まり，穂数が増加するとともに，シンク容量の大きな穂が形成されて1穂粒数も増加したものと考えられた．さらに登熟期後半までNARが高く維持されたことで1000粒重も増加した．以上の乾物成長経過および収量構成要素の形成の結果，生育後期重点施肥により，収量を15～50％増加させることが可能であった．一方で，成熟期が遅れること，外観品質の低下や子実タンパクの過剰，土壌の酸性化の助長などの普及技術化に向けて改善すべき課題も明らかとなった．
