雌株玉米的顶穗和腰穗均为单性雌花,用任何正常玉米的花粉分别给雌株玉米的顶穗和腰穗授粉均能结实。种其后代,一半为雌株,一半为正常株,呈1:1的分离比例。本文就雌株玉米的茎杆含糖量百分率的分布,消长动态和利用的可能性进行一些初步的探讨。现代农业科学正在朝着微观深入和宏观综合的领域发展。雌株玉米的茎杆作为农副产品能否进行加工利用,这是经济开发的新课题。早在1980年张光炼同志曾用竞明20型手持测糖仪对“成熟”(腰穗黄熟期)的雌株玉米茎杆进行了含糖百分率的测定,测得
The top and bottom waist of female plants were unisexual female flowers, and pollination of the top and middle ears of maize plants could be harvested with any normal maize pollen. Their offspring, half of the female plant, half of the normal strain, was a 1: 1 separation ratio. In this paper, some preliminary discussions on the distribution of percentage of sugarcane content in corn plants, the dynamics of their growth and the possibility of their utilization are given. Modern agricultural science is moving toward the field of micro-depth and macro-integration. Female corn stalk can be used as agricultural and sideline products processing and utilization, which is a new issue of economic development. As early as 1980, Comrade Zhang Guanglian had measured the percentage of sugars in the corn stalks of “mature” (yellow-eared wheat) by using the Jingming 20 hand-held glucose meter.
