摘要
以驻马店市农业科学院园艺所近年来培育的7个辣椒组合(品种)为试材,利用遮阳网模拟弱光胁迫,调查了在弱光胁迫下辣椒植物学性状及产量性状,以株高、茎粗作为参考指标,以叶面积、比叶干质量作为重要指标,以产量、叶绿素a/b值作为主要指标,对其弱光耐受性进行了综合评价。结果表明:弱光逆境胁迫导致辣椒植株增高、茎秆变细、叶面积增大、比叶干质量降低、产量及叶绿素a/b值均降低;且叶绿素a/b值与产量的变化幅度基本一致,该方法可用来鉴定辣椒不同组合的耐弱光性能。
With block light net simulating the low light condition, seven pepper combinations which were cultivated in Horticultural Institute of Zhumadian Institute of Agricultural Sciences in recent years were used to evaluate their low light tolerance by means of factor analysis. Botany traits and yield traits, plant height and stem diameter were reference index,leaf area and specific leaf weight were important indicators, but crop and chlorophyll a/b ratio were the most important indicators. The results showed that low light stress led to increase the plant high and leaf area, reduce stalks and specific leaf weight and yield and chlorophyll a/b ratio. The change of chlorophyll a/b ratio and yield were basically identical. The study accessed the low light tolerance of the different pepper combination successfully.
