The Transpiration Rate of Peach Leaves

he peach leaves were good materials for studying the cuticular transpiration because therewere not stomas in epidermis. The results showed : the proportion of epidermal cuticulartranspiration to total transpiration of leaves fluctuated in a day , the changes of the proportion ofprimary and mature leaves were 11. 79 ～ 32. 90%and9. 91 ～ 2.44%respectively. Thetranspiration rate of detached leaves decreased during 1 min and increased later and the reasonwas obscure. The diurnal variations of transpiration rate of leaves in different microclimate werecompared.The peaks of the diurnal variations of leaves in the east and west of the peach treeappeared at 11 :00 and 1 3 :00, respectively. The diurnal variation of leaves in the southernpart of the peach tree showed double peaks which appeared at 1 0 : 0 0 and 15 :0 0.
