Abstract

Abstract:

In order to provide a reference basis for reasonably promoting sugarcane tillering and constructing a reasonable population structure， the productivity differences and internal relationships of sugarcane varieties with different tillering characteristics were analyzed. 3 varieties including Guitang 29 with strong tillering， Guitang 42 with medium tillering and Guitang 03-2112 with weak tillering were selected as materials， the two-year field plot experiment was conducted to explore the characteristics of sugarcane varieties with different tillering characteristics and the factors involved in yield and their relationship. The results of the two-year experiment showed that the tillering ability of sugarcane was directly proportional to the tillering rate， and the difference of tillering rate among strong， medium and weak varieties reached a very significant level. The number of effective stems among different varieties also showed similar results. The effective stems of Guitang 29 with strong tillers was 20 575·hm^-2 more than that of Guitang 03-2112 with weak tillers， and the difference reached a significant level. Through the analysis of sugarcane quality， it was found that the sucrose content of Guitang 29 with strong tillering and Guitang 42 with medium tillering were significantly higher than that of Guitang 03-2112. The sucrose content of the main stems of these 3 varieties were higher than that of their tillering stems. Among them， the sucrose content of the main stems of these 3 varieties in 2019 were significantly higher than that of the tillering stems. The results of correlation analysis showed that in the process of sugarcane yield formation， the contribution of tillering rate and seedling emergence rate to yield was independent. There was a highly significant positive correlation between the number of effective stems per unit area and the tillering rate of sugarcane， but there was no significant negative correlation between the plant height and stem diameter of varieties with different tillering capacity and the tillering rate. Interestingly， there was a significant positive correlation between tillering rate and sucrose content. The above results showed that there was no internal correlation between the emergence and tillering of varieties in the process of sugarcane yield formation. Sugarcane varieties with strong tillering ability had high tillering rate， and more effective stems could be obtained by promoting tillering into stems， but varieties with medium and weak tillering ability had obvious advantages in plant height and stem diameter in yield formation. It could be seen that sugarcane varieties with different tillering ability could coordinate the situation of main seedlings and tillering seedlings， integrate the growth and development of important yield traits to form a reasonable proportion of main stem and tiller stem， so as to achieve high yield of sugarcane. Therefore， this study would provide a theoretical basis for building robust individuals and high-yield groups， giving full play to the productivity of sugarcane tillers， and realizing stable and high-yield cultivation.

摘要：

为分析不同分蘖力特性甘蔗品种的生产力差异及内在关联，为合理促进甘蔗分蘖及构建合理的群体结构提供参考，选用分蘖强的桂糖29号、分蘖中等的桂糖42号和分蘖弱的桂糖03-2112共3个品种为试验材料，采用单因素随机区组设计，进行2年新植试验，测定不同甘蔗品种的农艺性状、产量和品质，探讨不同分蘖特性甘蔗品种性状及产量形成的因素，并分析它们在产量形成中的相互关系。2年试验结果表明，甘蔗的分蘖力与分蘖率成正比，强、中、弱品种间的分蘖率差异达极显著水平；不同品种间的有效茎数也表现出相似的结果，分蘖力强的桂糖29号的有效茎数比分蘖力弱的桂糖03-2112多20 575条·hm^-2，差异达到显著水平；通过甘蔗品质分析发现，分蘖强的桂糖29号和分蘖中等的桂糖42号的蔗糖分显著高于桂糖03-2112，这3个品种的主茎蔗糖分均高于分蘖茎，其中，2019年3个品种的主茎蔗糖分显著高于分蘖茎。相关性分析结果显示，在甘蔗产量形成过程中，分蘖率和出苗率对产量的贡献是独立的；单位面积甘蔗有效茎数与分蘖率呈极显著正相关，但不同分蘖力品种的株高和茎径与分蘖率均呈负相关，但不显著；分蘖率与蔗糖分呈显著正相关。上述结果表明，在甘蔗产量形成过程中，品种的出苗和分蘖率没有内在关联，分蘖力强的甘蔗品种具有高分蘖率，促进分蘖成茎可以获得较多的有效茎数，但分蘖力中等和弱的品种在产量形成中具有明显的株高和茎径优势；可见，不同分蘖力的甘蔗品种可通过协调主苗和分蘖苗情况，综合重要产量性状的生长发育，形成合理的主茎和分蘖茎比例，从而实现甘蔗高产。该研究结果为构建健壮个体和高产群体、发挥甘蔗分蘖的生产力、实现稳产高产栽培提供理论依据。
