摘要: 水分胁迫条件下,玉米叶片光合速率下降,耐旱性较强品种光合速率下降幅度小于中等耐旱品种;开花期下降幅度大于小穗分化期;光合速率下降幅度与水分胁迫强度成正相关。复水后光合速率恢复程度亦与品种耐旱性、生育期及胁迫强度有关。

关键词: 玉米, 水分胁迫, 光合速率

Abstract: The photosynthetic rate of the leaf of maize decreases under water stress.Compared with moderate drought-tolerance,higher drought-tolerance has the lower reduction extent of photosythetic rate.The photosythetic rate at flowering period is reduced more than that at anthoecium-differentiation period when water stress occurres.The reduction extent of photosynthetic rate and the intensity of water stress shows positive correlation.The recovering degree of photosynthetic rate is related to the tolerant drought degree of va growth d development period and the intensity of water stress after rewatering.

Key words: Maize, Water stress, Photosyn thetic rate
