构成水稻产量内容的碳水化合物,早期研究已经证明,一部分是在抽穗前贮藏于茎秆里的,随灌浆而向穗部转运;另一部分是抽穗后新合成的。积累于抽穗前然后转入幼穗的碳水化合物,占稻穗中碳水化合物总积累量的百分
Early studies have shown that some of the carbohydrates that form part of the rice yield are stored in the stalks prior to heading and are transported to the spikes as grout; others are newly synthesized after heading. Carbohydrates accumulated before heading and then panicle, accounting for the percentage of total carbohydrate accumulation in the panicle
