摘要
本文对杂交水稻威优35,常规稻湘早籼1号,晚粳6647不同萌发时期的胚乳进行了电镜观察。结果表明:杂交水稻在萌发期间淀粉水解速度比常规稻快,表现出明显的生理优势。这一生理优势与杂交水稻幼苗的生长优势一致。
The present paper expounds on the study of endosperms in different germinatingstages of hybrid rice Weiyou 35 in comparison with those of common rices Xiang-zaoxian 1 and Wangeng 6647 achieved through scanning electron-microscope.The results show a visid superiorty that,in germinating stage,the hydrolyticrate of starch of hybrid rice is much sooner than that of common rices and thisphysiologic superiorty is in conformity with the growth superiorty of hybrid riceseedling stages.
