| 摘 要： | 通过对棉花不同时期去主茎叶、叶枝叶、果枝叶和全部叶片的研究,初步探讨了棉花叶源对库的影响.结果表明:无论蕾期还是盛铃期,叶片是棉花光合产物的主要来源,没有叶片棉花就不能正常生长,也很难保证其产量;不同部位的叶片中,主茎叶的作用显著,蕾期去主茎叶后株高日增长量减少0.5 cm以上,干物质积累明显下降,盛铃期则导致棉铃大量脱落,成铃平均减少2个以上;去果枝叶的作用相对较小,去叶枝叶几乎无影响.

| Abstract: | The main stem leaf,the leaf of leafy shoot,the leaf of fruit spur,and all the leaves at different time were remove to study the influence of these treatment on the source/sink.The results showed that no matter the squaring or peak boll setting stage leaf was the main source of photosynthesis,the cotton had no yield and could not live if no leaf left.In different spot leaf,the main stem leaf was important for cotton after removing,it could seriously influence cotton's growth.The daily growth decreased in 0.5... |
