在7种光周期下,比较了原产澳大利亚Glycine亚属10个种,和原产25°N的G.tomentella和Soja亚属3个种的生殖发育期。1、Glycine亚属对光周期的适应性比Soja亚属广,种间差别大。多数在12—13小时下发育快,而Soja亚属均为8小时发育快。2、Glycine属内,染色体组型GG的在8小时下发育最快,CC型12小时,BB型12—13小时,DD、FF型13小时,AA型13小时发育最快。3、Glycine亚属多数种植株下部形成闭花受精荚(Cleistogamous pod,上部形成正常受精花(Chasmogamous flower,隐花荚形成一般早于正常花,而Soja亚属只有正常花。4、两个亚属地理重叠地区(25°N)的G.tomentella与Soja亚属诸种,均表现8小时光周期下发育最快,而原产21°S的G·tomentella在12小时下发育最快。
Under 7 photoperiods, 10 species of Glycine subsp. Native to Australia were compared with 3 species of G.tomentella and Soja from 25 ° N origin. 1, Glycine subgenus adaptability to the photoperiod than the Soja subgenus wide, interspecific differences. Most developed rapidly in 12-13 hours, while subgenus Soja developed fast for 8 hours. In Glycine genus, the genotype GG developed most rapidly at 8 hours. CC genotype was 12 hours, BB genotype was 12-13 hours, DD and FF genotype was 13 hours, and AA genotype was the fastest at 13 hours. Most of the subgenus Glycine species formed Cleistogamous pod, the upper part of which formed the normal flower (Chasmogamous flower, which was earlier than the normal flower, but the subgenus Soja had only the normal flower.4, The G.tomentella and Soja subgenus in the geographically overlapped region (25 ° N) all showed the fastest photoperiod development in 8 hours, whereas G. tomentella native to 21 ° S developed fastest at 12 hours.
