将离体的小麦叶片用透明的玻璃压板压入水中,置于自然光下,人为造成低氧、低二氧化碳的逆境,7d后通过测定叶绿素含量,比较发现:Pato和宁麦 3号的单位重量的叶片内叶绿素含量下降量较小;白江西和水里占下降量较大。以单位重量的叶片内叶绿素含量下降量为选择指标,筛选出的耐光氧化小麦材料与目测、聚类分析结果是一致的。 Will be separated from the wheat leaves with a transparent glass plate pressed into the water, placed under natural light, artificially cause hypoxia, low carbon dioxide adversity, 7d after determination of chlorophyll content, found that: Pato and Ningmai 3 per unit weight Leaf chlorophyll content decreased less; white Jiangxi and water accounted for a larger decline. The declination of chlorophyll content in leaves per unit weight was taken as the selection index. The selected light-resistant and oxidative wheat materials were consistent with those obtained by visual inspection and cluster analysis.
