Abstract

In order to discuss photosynthetic characteristics of Cyclamen persicum leaves and effects of environmental factors on photosynthetic rate , the experiments were conducted to study diurnal changes and seasonal fluctuation of the net photosynthetic rate and major environmental factors .The net photosynthetic rate reaches peaks at 10 :22 and 13 :42 respectively in dry-heat conditions .And it reaches also peaks on June and October in one year respectively .Hard photosynthetic photon flux , high air temperature and low relative humidity result in sleeping at noon for Cyclamen persicum leaves .The diurnal changes and seasonal fluctuation of net photosynthetic rate are affected by major factors , i .e .photosynthetic photon flux , air temperature , stomatal conductance , transpiration and relative humidity as well .The net photosynthetic rate , the light-saturating photosynthetic rate and the light compensation photosynthetic rate of middle-part leaf are higher than those of lowerpart leaf .Shading and spraying are contributed to improving the microclimate condition of Cyclamen persicum growth , increasing anti-high-temperature and efficiency for sloar energy utilization , decreasing sleeping in summer .
