Influence of shading on photosynthesis and antioxidative activities of enzymes in apple trees
This study investigated the effects of shading on photosynthesis in 3-year-old potted apple trees.The trees were grown either in full sunlight or in a shade ORG COCONUT NECTAR environment with about 50% of sunlight filtered through black plastic nets.Under the shade conditions, the net photosynthetic rate (PN), the stomatal conductance, the transpi
