摘要
通过对黄秋葵Abelmoschus esculentus的3个品种021、018、024进行摘除花朵处理,观察其叶片数、分枝数的变化,测量其叶片长、叶片宽、叶片干质量、光合作用、叶黄素和β-胡萝卜素的含量,探讨摘花对黄秋葵叶黄素和β-胡萝卜素产量的影响。结果发现:摘花对不同品种黄秋葵的影响差异较大,其中对018的影响最大,摘花处理叶长和叶宽及光合作用均显著减少,叶片干质量、叶片数和分枝数显著增加,叶黄素和β-胡萝卜素的含量和产量均显著增加;024次之,摘花处理叶长、叶片干质量、叶黄素和β-胡萝卜素含量及产量均显著增加,其他没有显著变化;对021的影响最小;除叶黄素含量增加和光合速率降低外,其他没有显著变化。
Flowers of three cultivars of Abelmoschus esculentus （021, 018,024） were plucked to study the effect of plucking flowers on lutein and β-carotene content and yield, by measuring leaf number, branches, leaf length and width, leaf dry matter, photosynthesis, lutein and β-carotene content. The results showed that plucking flowers had different influence on 3 varieties. The variety 018 reduced its leaf length and width, as well as photosynthesis; but leaf dry matter and branches increased significantly. Meanwhile, its lutein and β-carotene content and yield also remarkably increased. 024 had no significantly change except increased leaf length, leaf dry matter, lutein and β-carotene content, and yield. The treatment had least effect on 021, with only increased lutein content and decreased photosynthesis.
