Abstract:

Objective】To study and compare the dynamic changes of boll components in the development of cotton bolls and to explore the dynamic development law of Gossypium barbadense L. and Gossypium hirsutum L. in southern Xinjiang in the hope of providing scientific theoretical basis for the management of high-yield and high-quality cultivation and high-yield and high-quality breeding of cotton.【Methods】The bolls of Xinhai No.25 and Xinluzhong No.37 were taken as the research objects, and the external traits of boll development and dry weight of boll components were compared, and besides, logistic fitting was also carried out for comparison. 【Results】External traits: the length, diameter and volume of the bolls reached their maximum values 9, 9 and 15 d later than those of land cotton, and were 15.539 mm, 7.167 mm and 3.4 cm3 less, respectively; the length-to-diameter ratio of island cotton was 0.725 more than that of land cotton; the bolls of island cotton had 3-4 chambers and 20 seeds; the chambers of land cotton had 4-5 chambers and 36 seeds. Boll traits: the dry weight of the boll shells, seeds and fibres of sea island cotton reached its maximum value 12, 9 and 3 d later than that of terrestrial cotton, and 0.419, 0.654 and 1.204 g lighter; the ratio of boll shells∶seeds∶fibres was 29∶46∶25 for sea island cotton, and 24∶43∶33 for terrestrial cotton; the dry matter of each component of the bolls of sea island and terrestrial cotton was fitted with the Logistic equation, and both showed the same dry matter as that of the land. Fitting results were "S" curve, island cotton and land cotton boll fresh boll weight, boll dry weight, volume with boll age change trends were all similar; Island cotton boll length, boll diameter and cotton seed dry weight entered and ended the vigorous growth time 1-4 d later than terrestrial cotton.【Conclusion】The single boll weight, boll chamber and cotton seed number of upland cotton are higher than that of island cotton, the boll period is shorter than that of island cotton, and the proportion of boll shell and cottonseed is lower than that of island cotton, which shows the characteristics of high lint content and significant single boll.

摘要:

目的】比较研究新疆南疆海岛棉与陆地棉生长发育中棉铃各组分的动态变化,分析海岛棉和陆地棉棉铃的动态发育规律,为棉花高产优质栽培管理及优质育种提供科学的理论依据。【方法】以新海25号和新陆中37号的棉铃为研究对象,对棉铃发育的外部性状、铃部各组分干重进行logistic拟合比较。【结果】外部性状:海岛棉铃长、铃径和体积达到最大值天数分别较陆地棉晚9、9和15 d,并分别减少15.539 mm、7.167 mm和3.4 cm3;海岛棉的长径较陆地棉高0.725。海岛棉铃室为3~4室,棉籽数为20粒;陆地棉为4~5室,棉籽数为36粒。铃部性状:海岛棉棉铃铃壳、棉籽和纤维各干重达到最大值,较陆地棉分别晚12、9和3 d,且分别轻0.419、0.654和1.204 g;铃壳∶棉籽∶纤维比海岛棉为29∶46∶25,陆地棉为24∶43∶33。海岛棉和陆地棉棉铃各组分干物质用Logistic方程拟合结果,均呈“S”型曲线,海岛棉和陆地棉的棉铃鲜铃重、铃壳干重、体积随铃龄变化趋势相似;海岛棉铃长、铃径和棉籽干重进入和结束旺盛生长的时间较陆地棉晚1~4 d。【结论】陆地棉单铃重、铃室和棉籽数等均高于海岛棉,铃期低于海岛棉,铃壳、棉籽所占比重低于海岛棉,表现为衣分高、单铃重的特性。
