摘要: 【目的】进行棉花果枝节间长度研究对于棉花株型的塑造具有重要意义。【方法】本研究通过对果枝节间长短不同的两个陆地棉中2549和中5081测定内源激素以及喷施不同的外源激素,探究棉花不同长度果枝节间的内源激素差异和喷施外源激素对棉花果枝节间长度的影响;同时对两个材料的果枝节间组织进行切片处理观察其细胞水平上的差异。【结果】果枝节间长的中2549内源激素IAA、GA3和ABA的含量都明显高于果枝节间短的中5081;喷施外源激素IAA、GA3和ABA都能使棉花果枝节间长度有一定程度的伸长;与中5081相比,中2549的果枝节间组织细胞明显较大,但细胞数量明显较少。【结论】本研究发现了不同棉花果枝节间长度材料在内源激素以及细胞水平上的差异,为棉花果枝节间长度分子机理探究奠定了基础。

Abstract: [Objective] It is of great significance for shaping plant architecture, strengthening the research on cotton fruiting branch internode length. [Method] In this research, two upland cotton materials Zhong2549(long branch internode) and Zhong5081(short branch internode) were used for the study of the endogenous hormone differences by measuring endogenous hormone of the fruiting branch internode of Zhong2549 and Zhong5081; and for the study of the influence to the internode length by spraying exogenous hormone to Zhong2549 and Zhong5081. The paraffin section technique was used to detect the cell morphology of the fruiting branch internode of Zhong2549 and Zhong5081. [Result] that the content of endogenous hormone IAA, GA3 and ABA in Zhong2549 were apparently higher than its in Zhong5081. Spraying exogenous hormone IAA, GA3 and ABA promoted the fruiting branch internode elongation. The section result showed that the cell size of Zhong549 was bigger than Zhong5081, and the cell density of Zhong2548 was less than Zhong5081. These indicated that the endogenous hormones which affect the fruiting branch internode length and the differences of different length fruiting branch internode in cellular level. [Conclusion] This study can provide some foundation and reference for the later research.
