Abstract

在大田条件下,以南疆主栽海岛棉和陆地棉为材料,研究棉铃发育过程中棉铃各部位的生理生化特征。结果表明,海岛棉铃壳叶绿素 a、叶绿素 b 含量极显著高于陆地棉,类胡萝卜素含量极显著低于陆地棉。海岛棉铃壳、种子、纤维中可溶性蛋白质含量、过氧化氢酶活性和抗坏血酸含量明显高于陆地棉,且纤维中过氧化物酶活性也高于陆地棉,铃壳中丙二醛含量低于陆地棉。海岛棉与陆地棉发育棉铃各部位生理生化的异质性是棉铃铃期、铃重、衣分和纤维长度、伸长率、比强度等种间差异的内在表现。

To study physio-biochemical characteristics in different parts of growing bolls, the major cotton varieties of sea island cotton and upland cotton were selected as materials. The results showed that the content of chlorophyll a and chlorophyll b in boll shell of sea island cotton were higher than that in upland cotton, the content of carotenoid in the boll shell was lower than that in upland cotton. The content of soluble protein, the catalase activity and the ascorbic acid content in the boll shell, seed and fiber of sea island cotton and the peroxidase activity in the fiber were higher than that in upland cotton, the malondialdehyde content were lower than that in upland cotton. There was an internal expression in the heterogeneity of physio-biochemical indexes of growing bolls between sea island cotton and upland cotton, which may have led to great difference in the boll period, boll weight, lint percentage, the fiber length, elongation and gouge strength, et al. in different cotton species.
