关于水稻根系吸收的碳酸向地上部转移的通路问题,看法不一。山田等认为是通过通气组织,而横田等则认为是通过与蒸腾有关的输导组织。而关于转移的形态,一般认为主要是无机碳酸,也有人认为大部分是以有机态转移。作者对根系吸收的碳酸的转移形态等问题进行了试验。实验方法1.供试植物碳代谢类型和通气系统发达程度不同的水稻、小麦(C_3植物)和玉 Different opinions have been expressed on the pathway of carbon dioxide uptake by rice roots into shoots. Yamada, etc. that is through the ventilation organization, while Yokota that is through the transpiration and conduction organization. The transfer of the form, generally considered mainly inorganic carbon, some people think that most of the organic state transfer. The authors tested the carbon transfer patterns of root absorption. Experimental methods 1. The test plants carbon metabolism and aerenchyma developed in different degrees of rice, wheat (C_3 plants) and jade
