Photosynthetic characteristics and N, P, K contents of Cyclamen persicum during the summer dormancy stage

Abstract: During the dormancy stage with high temperature and strong light in summer , the transpiration rate of Cyclamen persicum increased , which led to moisture decompensation , rise in stoma resistance , rise in illumination intensity and temperature , and fall in photosynthesis rate .At the same time , the massfraction of nitrogen increased slowly , that of phosphor decreased gradually , that of potassium first increased then decreased in the plant .The mass fractions of nitrogen , phosphor and potassium in the source leaves and roots decreased ;while in the corm , those of nitrogen and phosphor accumulated and that of phosphor unchanged .These changes were consistent with the behaviors of Cyclamen persicum in the dormancy caused by high temperature and strong light .
