读过“分枝水稻选择试验的初步报告”,(见復旦学报自然科学1956年1期),“对关於分枝水稻问题的幾點商榷”(见植物生理学通讯,1956年6期),“关於上海北郊的分枝水稻”(见科学通报,1954年4月号)及“关於分枝水稻问题”(见科学通报,1954年10月号)等幾文後,我有如下幾黠看法提出商榷。首先,蔡以欣先生认为“……产生分枝的节间……一般在淺水之下,其节上不太会有不定根的产生”。蔡先生把它作为和水稻分蘖区别的依據。我认为这是不恰当的,因为分枝节上只 Read the Preliminary Report on Selected Experiments in the Variation of Branches of Rice (Fudan Journal of Natural Science, 1956, 1), “Some Questions on the Issue of Branching Rice” (Phytophysiology Newsletter, Issue 6, 1956) I have the following opinions after several passages such as the “Branches of Rice in the Northern Suburbs of Shanghai” (Bulletin of Scientific Bulletin, April 1954) and the “Question on Branches of Rice” (Science Bulletin, October 1954) Put forward a discussion. First of all, Mr. Cai Yixin believes that “... the internodes that produce branches ... are generally less likely to have adventitious roots in shallow water.” Mr Choi regards it as the basis for distinguishing rice tillers. I think this is not appropriate, because the branch section only
