前言树木光合作用的研究虽进行较长时间,但大多是在一定的标准条件下单独的光合测定,或是研究不同树种的比较光合;而对在树木年生长周期中,测定其光合作用则注意不够。至于研究林木年生长中干物质生产、分配与器官生长的关系则更少。但这种研究在理论和实践方面都是重要的。本文目的在于研究马尾松一年生实生苗干物质生产、分配与器官生长的关系,为揭示松苗的净同化率、干物质生产分配以及生长的规律提供线索。
Although the research on photosynthesis of trees has been carried on for a long time, most of the studies on photosynthesis of trees have been conducted under certain standard conditions or the photosynthesis of different tree species has been studied. However, the photosynthesis of trees during the annual growth cycle has been measured not enough. As for the study of dry matter production in tree growing year after year, there is less relationship between distribution and organ growth. But such research is important both in theory and in practice. The purpose of this paper is to study the relationship between dry matter production, distribution and organ growth in annual seedlings of Masson pine and to provide clues for revealing the net assimilation rate, dry matter production and distribution and growth of pine seedlings.
