Description
We observed that the alfalfa appears diurnal fluctuation of transpiration very clearly by in its flower initial stage. They always appear two transpiration peaks in the morning and afternoon, respectively. In the fruiting stage as well as in flowering stage, the diurnal fluctation of alfalfa was lesser with smaller transpiration retes. Both of the diurnal fluctuations in the two stages are strongly affected by the leaf temperature. In the flower initial stage, from 5:30 to 9:30 a.m., the transpiration rate increases with the increase of leaf temperature. After 9:30, while the transpiration drops down rapidly, till afternoon 16:30 p.m. the transpiration slightly increased. As we know, the transpiration has a lot of important functions in plants growing process. But we failed to find out any direct relations between transpiration and plant yields in our experiments.
