研究认为在结角层中的上层角果经济性状最好,下层渐差,各层单位面积角果皮的生产力自上而下随累计角果皮面积指数的增加而降低,两者呈二次方程关系。角果的籽粒重量不仅与开花先后有关,更主要的与光照条件有关。各一次枝果序的生产力与它在结角层中位置的高低和果序的长度有关。理想的结角层一次枝序的结角起点与主序基本相平,并均有较长的果序和较高的生产力。
The results showed that the economic characters of the upper pods in the horniness layer were the best, and the lower ones were gradually worsened. The productivity of the horn pods per unit area decreased from top to bottom with the increase of the accumulated cortical area index, which showed a quadratic equation . The grain weight of the pod is not only related to flowering, but also to the light conditions. The productivity of each branch and shoot is related to its position in the stratum corneum and the length of its sequence. The ideal knot of the first branch of the knot starting point and the main sequence of the basic flat, and have longer sequence and higher productivity.
