摘要
采用灰色关联分析法,对影响油菜产量的光合生理指标进行了分析。结果表明,影响油菜经济产量各光合生理指标的关联序为:叶绿素总量(r5=0.6358)>叶绿素a含量(r3=0.6118)>叶绿素b含量(r4=0.5948)>阴天光合速率(r2=0.5827)>叶绿素a/b比值(r7=0.5762)>晴天光合速率(r1=0.5737)>类胡萝卜素含量(r6=0.5499)。影响油菜生物产量的各光合生理指标的关联序为:叶绿素总量(r5=0.7813)>叶绿素a含量(r3=0.7311)>叶绿素b含量(r4=0.7152)>晴天光合速率(r1=0.7023)>叶绿素a/b比值(r7=0.6715)>阴天光合速率(r2=0.6499)>类胡萝卜素含量(r6=0.6366)。影响油菜经济产量和生物产量的主导因素是叶绿素含量。
The aim of this study was to use correlative analytic method to analyse photosynthesis physiological target and its influence on rape yield. The results showed the correlative sequence of influencing economic yield of rape: chlorophyll total content (r5= 0.6358) > chlorophyll a content (r3=0.6118) > chlorophyll b content (r4=0.5948) > photosynthetic rate in cloudy (r2=0.5827) > chlorophyll a/b ratio (r7=0.5762) > photosynthetic rate in fine (r1=0.5737) > carotenoid content (r6=0.5499), and the correlative sequence of influencing organic yield of rape: chlorophyll total content (r5=0.7813) > chlorophyll a content (r3=0.7311) > chlorophyll b content (r4=0.7152) > photosynthetic rate in fine (r1=0.7023) > chlorophyll a/b ratio (r7=0.6715) > photosynthetic rate in cloudy (r2=0.6499) > carotenoid content (r6=0.6366). It was chlorophyll content that dominants factor to influence economic yield and organic yield of rape.
