Abstract

Study on growth rhythm of grafted clones from Acer truncatum plus trees introduced into Jinning county.

Abstract

Investigation and analysis on the graft survival rate of Acer truncatum plus trees and plant height, basal diameter, node numbers was made during 2007. The result showed that: the graft survival rate of No. 92 was the highest (94%), and No. 88 was the lowest (62.5%). The differences among the 12 clones were extremely significant. Plant height of grafted clones growth concentrated on the May-June, and basal diameter growth concentrated on the May-July, after July which became slowly. The node numbers growth once every two months, the largest in May, then gradually reduced. At the same time the fitting effect with Logistic equation was significance.
