摘要: This investigation was begun during the summer of I9I5 and carried on for about a year. Preliminary observation showed that leaves growing in sun at south periphery were thicker than shade center same tree. The purpose to find out exact differences structure from two positions, compare by measurements factors environments which growing. measured light, evaporating power air, temperature, humidity wind. A study transpiration also made I9I6.
