Abstract:
Apple seedlings of ‘Gala’ in pot,were taken as materials,the effects of different water stress treatment on the relative leaf conductivities,POD activity,SOD activity,CAT activity,MDA content,root activity were studied with potted apple seedlings.In order to learn the physiological adaptability of apple seedlings of ‘Gala’ to water stress.The results showed that under water stress condition the relative leaf conductivities,MDA content,were increasing in general and reached the highest values of 53.254%,15.325 mmol?g-1,respectively at the 18th days,POD activity,SOD activity,CAT activity,root activity at first increased,then decreased.In conclusion,apple seedlings grew well under the early water stress,under the mid water stress seedlings showed a more complex process of change；under the late stage stress the seedlings seriously injured.It showed apple seedlings of ‘Gala’ drought tolerance,but it should be watered on time；otherwise their growth will be affected.
