摘要
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.
