干旱胁迫对芸豆籽粒干物质积累的影响及动态模型的建立
Effect of drought stress on seed dry matter accumulation of kidney bean and the construction of dynamic model
摘要
Abstract
In order to study the effect of drought stress on seed dry matter accumulation of kidney bean and establish the dynamic equation ,we selected 2242 speckled kidney bean cultivars and performed a pot experiment with three drought treatments including growth stages ,drought severity and duration .The results showed significant influence of drought stress on seed dry matter accumulation .For the drought treatment ,reduction in yield followed the order of CK >moderate drought > severe drought .Grain dry accumulation followed “S” curve and can be described by the Logistic mod-el ,with the coefficient of determination being above 0 .98 .关键词
