水氮互作对春小麦叶片叶绿素含量及光合速率的影响
Effect of water and nitrogen interaction on chlorophyll content and photosynthetic rate of spring wheat leaves
摘要
Abstract
A random block design experiment with three levels was conducted to explore the effect of water/nitrogen interaction on the chlorophyll content and photosynthetic rate of spring wheat variety Ningchun 4. The results showed that suitable nitrogen could evidently increase the chlorophyll content and photosynthetic rate. Under drought and good water conditions, the Pn, IWUE of high-nitrogen level was higher than the other nitrogen levels. Under the condition of three nitrogen levels, with the aggravated of water stress, the Chlorophyll content, carotenoid, IWUE and Pn demonstrated a trend of increasing. Correlation analysis showed that there was a significantly linear positive correlation between IWUE and Pn, but negative with Tr and Gs The relationship between Pn and Gs , IWUE were different in various treatments.关键词
