中华蚊母光合特性初步研究

Preliminary Study on Phytosynthesis Characteristics of Distylium Chinese（Franch）Diels.

用CB-1102型便携式光合仪测定了中华蚊母（Distylium Chinese（Franch）Diels．）的主要光合指标，结果分析表明：中华蚊母光合13动态呈明显的双峰曲线，峰值分别出现在中午12：00和下午16：00，在中午14：00左右表现明显“光合午休”现象，最大净光合速率偏低，出现在中午12：00点，仅为9．37μmolom-2·s-1。

The main phytosynthesis index of Distylium Chinese （Franch）Diels were measured with CB-1102 Portable Phytosynthesis Instrument.The results showed that the daily progress of phytosynthesis was a obvious double-peak curve.The peak values were at 12：00 am and 16：00pm respectively.Light noon break occurs at about 14：00 pm. The most phytosynthesis rate occurred at 12：am and was only 9.37μmolom^-2·s^-1.
