Physiological and ecological characteristics of high yielding varieties in rice plants. II. Leaf photosynthetic rates.

Effects of a Reduction in Soil Moisture from One Month beforeFlowering through Ripening on Dry Matter Production and Ecophysiological Characteristics of Wheat Plants

“…7 and 10), perhaps because the plants in the D plot did not suffer from suffi ciently severe water stress as mentioned above and also because they had a better-developed root system (Fig.4 and Table 5). It has been reported that leaf senescence is delayed in plants with a well-developed root system (Jiang et al, 1988;Hirasawa et al, 1994Hirasawa et al, , 1998Kondo et al, 2000), and might be the cause of differences in both dry matter accumulation and yield between various cultivars and strains of rice (Jiang et al, 1988), sorghum (Amber et al, 1992), soybean (Ookawa et al, 1999b) and maize (Ma and Dwyer, 1998;Kondo et al, 2000) plants.…”

Overexpression of the phytochrome B gene from Arabidopsis thaliana increases plant growth and yield of cotton (Gossypium hirsutum)

“…Improved stomatal conductance was observed because of an increase in transpiration rate. This is because there is a close correlation between stomatal aperture and photosynthetic rate (Jiang et al, 1988;Hirasawa et al, 1992). Importantly 90% of the water loss takes place through stomata which cover only 1% area of the leaf.…”

A Comparison of the Accumulation and Partitioning of Nitrogen in Plants between Two Rice Cultivars, Akenohoshi and Nipponbare, at the Ripening Stage

“…Akenohoshi is a cultivar of panicle-weight type and produces heavy dry matter and grain compared with Nipponbare, a Japanese standard cultivar of panicle-number type. The leaves of Akenohoshi maintain a higher rate of photosynthesis throughout the ripening stage than the leaves of Nipponbare (Jiang et al, 1988a;Jiang et al, 1988b). It is extremely important for future breeding of high-yielding cultivars to clarify the physiological characteristics that are related to the maintenance of a high rate of photosynthesis during senescence at the ripening stage.…”
