引言 茶树在冬季同化的光合产物不仅是形成越冬芽的碳源,而且也为根系在早春合成一些氮化物提供了碳架和能源(杨贤强,1985);在春季同化的光合产物,对茶树生长也有很大的影响。修剪对这两部分物质在体内的代谢变化,目前尚未报道。本文应用同位素~(14)CO_2分冬春两季饲喂茶树,研究了修剪对它们在体内代谢的影响,旨在探明修剪与冬春季光合产物代谢的关系,以期为生产实践提供理论参考。
Introduction The photosynthetic products assimilated by winter tea plants are not only the carbon source for the formation of overwintering buds, but also provide the carbon framework and energy for the root system to synthesize some nitrides in the early spring (Yang Xianqiang, 1985); photosynthetic products assimilated in the spring also have some effects on the growth of tea plants Great impact. Pruning of these two parts of the body’s metabolic changes, has not been reported. In this paper, we used isotope 14 CO_2 to divide the tea tree in the winter and spring seasons to study the effect of pruning on their metabolism in vivo. The purpose was to find out the relationship between pruning and the metabolism of photosynthate in winter and spring so as to provide a theoretical reference for the production practice.
