【摘要】 <正> 高产栽培和培育高产品种都需使作物的生长和发育能充分利用当地生态条件,创造有利的形态结构,实现高产。因此,不同地区有主要靠主茎、主穗或分枝、分蘗增产,靠粒多、荚多或大粒、大穗增产等各种不同的高产结构,形成生育节律和成熟期互不相同的各种生态类型。Ф.М.库別尔曼把被子植物一生中结实器官的形成过程分为十二更多还原

【Abstract】 Present paper studied morphological ontogenesis of fruit-bearing organs of soybean,characters of organ ontogenesis of different soybean subspecieses and etc, Generally earymaturing types of soybean pass through stages of organ ontogenesis faster than late-maturing types. Stage Ⅱ, Ⅴ and Ⅺ of organ ontogenesis of early-maturing types are shorter. To a great extent early-maturing characters of varieties relate to speed of passing through stages Ⅱ. Sgeed of passing through stages of organ ontogensis of soybean with same growing period is different. Their developments in different stages of organ ontogenesis meet with obstruction due to various reasons. Generally the differences of developments are not easy to find by using rherologicgical chservatior. using the method of morphological ontogenesis of organs, we can study characters of growth and development and relations with envirenment in detail. This method can be a staff gauge of biologicalstudy of soybean.更多还原
