Using conventional hybridization or transgenic technology to improve photosynthetic capacity of rice in our country, it is important to choose correct c4 plants which have high photosynthetic capacity and water use efficiency such as echinochloa rusgalli and sorghum
選擇光合性能優勢突出的c _ 4植物材料（如長芒稗、高粱等） ，用於轉基因或傳統育種來改良我國旱稻或水稻，有效改善旱稻或水稻的光合生理特性，提高光合速率。 -
With the increase of exposure time, the antioxidative ability of spirodela polyhiza dereased, sod and ap activities were induced, and asa content of treated plants were always lower than those of control plants, but the proline ( pro ) contents in treated plants increased. these factors would break the balance of the metabolism of ros and the active oxygen accumulation in leafy thallus of spirodela polyhiza could be the result, the membrane lipid peroxidation was accelerated ( mda content increased ), ultra - microstructure of chloroplast was damaged, photosynthetic capacity dereased, biomass ( dry weight ) reduced
實驗研究結果如下： （ 1 ） uv - b輻射處理后前2天，紫萍超氧化物歧化酶（ sod ）和抗壞血酸過氧化物酶（ ap ）等抗氧化酶系統有不同程度的升高，隨著uv - b處理時間的延長，紫萍體內抗氧化保護系統能力下降， sod和ap的活性下降，並且非酶類抗氧化物質抗壞血酸（ asa ）含量一直低於對照組，而脯氨酸（ pro ）的含量則一直在升高。 -
Interestingly, it was observed that the photosynthetic capacity in the aging plant declined earlier in leaf organs than in non - leaf organs, suggesting that non - leaf organs are still functional in the later development stages, when leaves have been yellowing and exhausted
幾種作物非葉器官結構和功能的研究通過對非葉器官和功能葉光合特性的比較研究，發現不同種作物非葉器官具有與功能葉不同的光合特性。 -
3. stomata characteristic is very important to improve photosynthetic capacity. the stomata of c4 plants such as echinochloa rusgalli, maize, are larger than c3 plants such as rice and stomata density of c4 plants is less than c3 plants
C _ 4植物長芒稗、玉米等氣孔較大，但單位面積氣孔數少，水稻及其雜交後代的氣孔器大小顯著小於c _ 4植物，而ygfl的氣孔器大小略大於其母本。
