Study on the Photosynthetic Dynamic Variation of Phyllostachys edulis

  • Received Date: 2004-11-20
  • Using Li-6400,the photosynthetic dynamic variation of Phyllostachys edulis was determined in deferent time scales.Meanwhile,the annual variation of chlorophyll content was studied.The results showed the diurnal variation of net photosynthetic rate(Pn) changed with season,bimodality in summer and autumn,and single peak curve in winter and spring.Stoma partly shut was the chief reason for photosynthetic midday depression in summer and autumn.The annual variation of photosynthesis followed a three-peak curve,peaks occurred in March,June and August,and the annual mean of Pn was 6.03 μmol·m-2·s-1.The annual variation of chlorophyll content was bimodality,peaks occurred in February and October,and the annual mean of chlorophyll content was 2.18 mg·g-1.Comparing this paper's results with others,the author presumed the different climates and different study methods were the chief reasons that probably resulted in discrepancies in those study results.

Abstract: Using Li-6400,the photosynthetic dynamic variation of Phyllostachys edulis was determined in deferent time scales.Meanwhile,the annual variation of chlorophyll content was studied.The results showed the diurnal variation of net photosynthetic rate(Pn) changed with season,bimodality in summer and autumn,and single peak curve in winter and spring.Stoma partly shut was the chief reason for photosynthetic midday depression in summer and autumn.The annual variation of photosynthesis followed a three-peak curve,peaks occurred in March,June and August,and the annual mean of Pn was 6.03 μmol·m-2·s-1.The annual variation of chlorophyll content was bimodality,peaks occurred in February and October,and the annual mean of chlorophyll content was 2.18 mg·g-1.Comparing this paper's results with others,the author presumed the different climates and different study methods were the chief reasons that probably resulted in discrepancies in those study results.
