【摘要】 以高蛋白含量大豆品种东农42(试验号302)及其极矮化突变体HK11(试验号201)、高脂肪含量品种东农47(原称东农163,试验号301)及其叶绿素缺失突变体HS821(试验号48)为材料,分别从不同生育期及不同节位对叶绿素含量进行研究。结果表明:叶片所含叶绿素a/b的比值约为2.5∶1;节位、生育期不同叶绿素含量也不同,表现为,随着节位上升,叶片叶绿素含量呈不断下降趋势;从开花结荚期(7月6日)到鼓粒初期(7月26日),叶绿素含量不断增加,鼓粒初期以后,叶绿素含量不断下降。更多还原

【Abstract】 In this text,we studied the content of chlorophyll from different growing period and different knots.Taking the high protein strains of soybean,Dongnong 42(the experience number 302),extremely short mutant HK11(the experience number 201),high fat strains Dongnong 47(we called Dongnong 163 before,the experience number 301)and the chlorophyll defected mutant-HS821(the experience number 48)as the materials.The results showed that the chlorophyll a/b of the leaf blade was 2.5∶1.Different knots and different growing period had different content of chlorophyll,that was,with the knots increasing,the chlorophyll content of leaves declined.The chlorophyll content increased constantly from flowers and pod bearing period to the early seed maturing period,after that,the chlorophyll content declined constantly.更多还原
