Effect of Chilling Temperature on Plant Metabolism of Hevea brasiliensis

Wang Yi-ron, Lin Hong-xian and Guo Zun-yun   

Abstract: The occasionally cold current from the north often hits some regions in Southern China. It Causes a sudden fluctuation of temperature and brings chilling injury to those temperature sensitive tropical plants. The experimental results indicated that chilling temperature had a marked influence on plant metabolism of Hevea brasitiesis. With the temperature dropping below the optimum, as its period prolonged, the normal metabolism in the rubber tree was changed. The catabolism of carbo- nhydrate, nitrogen and phosphorus metabolism were all enhanced and their syntheses were inhioited particularly the toxic substances, e.g. ammonia, was accumulated in the plant.
