图3 自然光照条件下不同结荚习性大豆品种顶端花序发育过程的解剖学观察 A: 出苗后24 d, 中黄13出现顶端花序原基; B: 出苗后30 d, 中黄13花序上出现小花原基; C: 出苗后36 d, 中黄13花序伸长, 小花原基进一步分化; D: 出苗后40 d, 中黄13花序上最后小花的雌蕊原基已分化完成; E: 出苗后24 d, 中黄24茎顶为营养生长阶段; F: 出苗后30 d, 中黄24茎顶仍为营养生长阶段; G: 出苗后36 d, 中黄24茎顶还处在营养生长阶段, 但花序下部已有花原基出现; H: 出苗后40 d, 中黄24茎顶出现小花原基; I: 出苗后12 d凤交66-12的茎顶处于营养生长阶段; J: 出苗后20 d, 凤交66-12已分化出顶端花序原基; K: 出苗后24 d, 凤交66-12的小花原基形成并分化; L: 出苗后32 d, 凤交66-12顶端花序上的小花已经基本分化完毕。ARP: 茎顶花序原基; C: 心皮; FP: 花原基; S: 雄蕊; SAM: 茎顶分生组织; TLP: 三出复叶原基。Bar: 200 #cod#x003bc;m。
Fig. 3 Anatomic observations on the terminal raceme developmental process of soybean varieties with different stem termination types under the natural photoperiod A: the apical raceme primordium produced in the shoot tip of Zhonghuang 13 at 24 days after emergence; B: some flower primordia produced in the terminal raceme of Zhonghuang 13 at 30 days after emergence; C: the terminal raceme of Zhonghuang 13 elongated and the flower primordia further differentiated at 36 days after emergence; D: the carpel primordium of the terminal flower developed in the raceme of Zhonghuang 13 at 40 days after emergence; E: the shoot tip of Zhonghuang 24 was vegetative bud at 24 days after emergence; F: the shoot tip of Zhonghuang 24 was vegetative bud at 30 days after emergence; G: the shoot tip of Zhonghuang 24 was vegetative bud at 36 days after emergence, and flower primordium produced at the bottom of the inflorescence; H: the flower primordium produced in the terminal of Zhonghuang 24 at 40 days after emergence; I: the shoot tip of Fenjiao 66-12 was vegetative bud at 12 days after emergence; J: the apical raceme primordium produced in the shoot tip of Fenjiao 66-12 at 20 days after emergence; K: some flower primordia produced in the raceme of Fenjiao 66-12 at 24 days after emergence; L: some flowers developed in the raceme of Fenjiao 66-12 at 32 days after emergence. ARP: apical raceme primordium; C: carpel; FP: floral primordium; S: stamen; SAM: shoot apical meristem; TLP: trifoliate leaf primordium. Scale bar: 200 #cod#x003bc;m.
