摘要:

对‘黑晶’等4个杨梅品种果实成熟期的光合参数进行测定,结果表明:不同杨梅品种的光合速率存在显著差异,其中以‘黑晶’杨梅的净光合速率最高。4个品种的光饱和点均在600μmol·m-2,s-1左右。光合速率的日变化均呈单峰曲线变化,峰值出现在10:00—12:00。2年生叶片的光合速率只有1年生叶片的33.9%-52.8%。

Abstract: The photosynthetic characteristics of four red bayberry (Myrica rubra) cultivars including ‘Heijing' were examined during the mature period. The results showed that the net photosynthetic rate(Pn) was significantly different among different cuhivars, and ‘Heijing' showed higher Pn than others. The light saturation point of the four cuhivars was about 600 μmol·m^-2,s^-1. The diurnal variation of photosynthesis showed a single-peak curve, the peak appeared at 10 o'clock to 12 o'clock. The photosynthetic rate of the biennial leaves was about 33.9%-52.8% of that of annual leaves.
