Variation Analysis on Branch and Leaf Traits of Acer truncatum Bunge Clones at Young Stage
摘要
Abstract
To select superior varieties of Acer truncatum Bunge clones,six clone populations from selec-tive breeding were chosen to analyze the variability of 1 4 traits,such as growth,branch gesture,leaf shape and leaf color.And colorimeter was firstly employed to define the leaf color quantitatively.The results were as fol-lows:(1 )The variation coefficients of 1 4 traits ranged from 0.0439 to 0.3680,and there were all highly sig-nificant or significant differences except ground diameter (X2 ),petiole curvature (X1 1 ),leaf color value a (X1 3 )and leaf color value b (X1 4 ).It indicated that the variations of branches and leaves were abundant. (2)Except the leaf color value a and leaf color value b,the repeatability of branch and leaf characters were between 0.5343 and 0.8380,which suggested that these traits were moderate to high genetic control charac-ters.It indicated that environment had low effects on most traits.(3)Correlation analysis indicated that seed-ling height (X1 )was highly significantly positively related to branch curvature (X4 ),which showed that the clone populations growing faster and higher possessed softer and more pliable branches.关键词
