中国科学院生物学部所属的研究单位,近两三年来进行了准备应用放射性同位素的設备条件和培养干部的工作。1958华大跃进以来,放射性同位素应用到生物学的研究才增加起来,在这短短一年时間里,由于党的領导与支持和工作人員的努力,已取得了一定的成績。光合作用及其所产生的同化物貭的运轉是影响作物产量的主要因素之一。在总結农业丰产經驗的工作中,更感到这一問題有深入研究的必要,于是利用碳14研究了水稻和小麦成熟期的光合作用同化物貭的积累、运轉与分配。証明了水稻子粒成熟时无麦芽糖并非淀粉酶不活动,而是水解出来的麦芽糖迅速被磷酸化及“麦芽糖激酶”轉化为蔗糖。在水稻成熟期間,叶子同化物主要供給本蘗上的穗,各叶間及各有效分
The research institutes affiliated with the Chinese Academy of Sciences have carried out preparations for the application of radioisotope equipment and cadre training in the past two to three years. Since the Great Leap Forward of 1958, the application of radioisotopes to biology has only increased. In this short year, due to the leadership and support of the party and the efforts of staff, some achievements have been made. Photosynthesis and its production of assimilate 貭 is one of the main factors affecting crop yield. In the process of summing up the experience of agricultural bumper harvest, it is felt that this issue is more deeply investigated. Therefore, the accumulation, turnover and distribution of photosynthetic assimilate 貭 in the ripening stage of rice and wheat were studied using carbon 14. It was proved that maltose was not amylase in rice grain at maturity, but maltose hydrolyzed quickly was phosphorylated and “maltose kinase” was converted to sucrose. During rice ripening, leaf assimilates are mainly supplied to the spike on the tiller, the leaves and the effective points
