Abstract
s: Seedlings of Xianglin No.5 were chosen as experimental materials, which were grown in 8 substrates with different water contents, and the difference of physiological characteristics of Camellia oleifera seedlings was analyzed. The results that under water stress condition the relative leaf conduction rate, MDA content and soluble sugar content were increasing in general and reached the highest values of 56.357%,13.654 mmol·g-1, 0.295mg·g-1, respectively in 70 d. POD activity, SOD activity, CAT activity, root activity at first increased, then decreased, while the chlorophyll content was decreasing to the lowest value of 0.552 mg·g-1 in 70 d. In conclusion, C.oleifera 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 is important that C. oleifera seedlings of Xianglin No.5 is in drought tolerance, but it should be watered on time;otherwise their growth will be affected.关键词
