Effect of P2O5 on Photosynthetic Physiology of Soybean Cultivars with Different Quality Types
摘要
Abstract
Six semi-determinate soybean cultivars of three seed quality types (common, high oil and high protein) were used to study the effect of different P2O5 amount (0,82.5,165.0 kg-ha-1 )on soybean photosynthetic physiological indexes. The results showed that phosphorus level significantly affected photosynthetic rate ( Pn), stomatal conductance ( Gs), transpiration rate (Tr) ,LAI and water use efficiency (WUE) of different quality type soybeans from flowering to grain-filling. And the photosynthetic physiological indicators improved under phosphorus treatment. In addition,in later growth stage the photosynthetic physiology indexes had a slow falling rate under phosphorus treatment,and the high-protein type had the lowest descending rate under high phosphorus(165.0 kg-ha-1 ) treatment.关键词
