摘要：

通过对两种不同培养（海沙培养和河沙培养）基质下红鳞蒲桃幼苗的光合生理日变化特征研究，表明在海沙环境中生存的红鳞蒲桃幼苗的光合速率、蒸腾速率及气孔导度比在河沙环境中生存的幼苗均较大。在两种环境中的幼苗的光合速率和气孔导度都呈现“双峰”曲线的变化趋势，且第一个峰值大于第二个峰值。幼苗的蒸腾速率呈现“波浪”渐减曲线的变化趋势。

Abstract:

Study on the photosynthetic diurnal variation characteristics of Syzygium hancei Merr.et perry seedings through the filter media of two different culture，including sea sand culture and river sand culture. The results showed that photosynthetic rate, transpiration rate and stomatal conductance of Syzygium hancei Merr.et perry seedlings in the environment of sea sand are greater than in the environment of river sand. Photosynthetic rate and stomatal conductance have shown "peaks" of the trend curve, and the first peak is greater than the second peak in both the environment. Transpiration rate of the seedings is a "wave" in the trend of decreasing curve.
