Effect of Drought Stress on the Photosynthesis Characteristic of Strawberry

摘要: The test material is strawberry varity Tudla.Mixing vermiculite, chickenfeces and pearlite under pro rata 1∶1∶1 for culture medium. Strawberry’s photosynthesis responsed to different arid degree(relative water content 80%, 60%,40%,20%). result indicated that 60 % 80 relative strawberry’s Pn high,their"split-blip" "the midday rest" phenomenon obvious. 40% has"split-blip"and"the phenomenon,but the speed has droped. 20% vanish "split-blip" phenomenon, nearly stop.
