Effect of Leaf Quantity Change on the Growth of Acer truncatum

  • Received Date: 2003-12-25
  • The effects of harvesting 1/3 of the leaves, 2/3 of the leaves, and 3/3 of the leaves on the growth of A.truncatum were studied. The results showed that the harvest quantity and harvest season significantly affected the tree height, base diameter,leaf area and leaf biomass dry weight, but there was no significant difference on the crown. There were positive effects of harvest quantity increase on growth of the tree. The effects of harvest leaf in June were more than in April, and in April were more than in August. Harvest 3/3 of leaves in April significantly harmed the increment of tree height,basal diameter,leaf area and leaf biomass dry weight. Harvest leaf in June significantly affected the increment of the tree height, basal diameter,but there was no significant difference on leaf area and leaf biomass dry weight.

Abstract: The effects of harvesting 1/3 of the leaves, 2/3 of the leaves, and 3/3 of the leaves on the growth of A.truncatum were studied. The results showed that the harvest quantity and harvest season significantly affected the tree height, base diameter,leaf area and leaf biomass dry weight, but there was no significant difference on the crown. There were positive effects of harvest quantity increase on growth of the tree. The effects of harvest leaf in June were more than in April, and in April were more than in August. Harvest 3/3 of leaves in April significantly harmed the increment of tree height,basal diameter,leaf area and leaf biomass dry weight. Harvest leaf in June significantly affected the increment of the tree height, basal diameter,but there was no significant difference on leaf area and leaf biomass dry weight.
