田间试验有助于甘蔗农艺性状与光能利用关系的研究。用三种不同分叶型态的品种,ROC_1(低蘖)、F_(160)(中等)和71—296(高蘖),发现ROC_1可以算是一个高光效的品种。结果显示ROC_1如下的一些农艺性状,优于其他品种: 1.良好的叶/宁排列——ROC_1品种均匀的叶片分布和较低的叶面积指数,意味着其整个植株冠层光幅射高效分布的可能性。 2.高的特效的叶面积——ROC_1在七月份时有较高的特效的叶面积,保证其有较高的光能利用潜力。 3.强的气候适应性——ROC_1在热的气候时有高的净同化率,和对荫蔽反应不敏感显示其优于大面积栽培品种F_(160)。
Field trials are helpful to the research on the relationship between agronomic traits and light energy utilization in sugarcane. Using three different leaf type cultivars, ROC_1 (low tiller), F_ (160) (medium) and 71-296 (high tiller), ROC_1 was found to be a high light efficiency variety. The results showed that some of the agronomic traits of ROC_1 were better than those of other cultivars: 1. Good leaf / shoot arrangement - uniform leaf distribution and low leaf area index of ROC_1 means that the whole plant canopy light radiation is highly distributed The possibility of. 2. High Specific Leaf Area - ROC_1 had higher specific leaf area in July, guaranteeing higher potential for light utilization. 3. Strong climatic adaptability - ROC_1 has a high net assimilation rate in hot climates and is insensitive to shading response, indicating that it is superior to F_ (160) in large-area cultivars.
