Response on Diurnal Variation of Leaf Photosynthesis-transpiration to Environment Factors for No-tillage Corn
摘要
Abstract
Field experiments were conducted to measure the diurnal change of photosynthesis-transpiration of the ordinary corn "Liaodan 527" and environmental factors in two sunny days.The results showed:the diurnal variations of photosynthetic rate (A) and transpiration rate (E) were single peak curves; There was a highly significant positive linear correlation between photosynthetic rate (A) and transpiration rate (E),and the correlation coefficients respectively were 0.91 and 0.827; The primary factors affecting photosynthesis-transpiration were PAR and△e.关键词
