Variation Analysis on Growth Traits in Seedlings of A Rare Oil Tree Species Horsfieldia panduri folia
摘要
Abstract
The seeds of 11 Horsfieldia pandurifolia trees from 5 habitats were propagated on artificial conditions. The growth traits of 543 one-year seedlings, including plant hight, basal diameter, number of branch, total length of branch per individual, under branch hight and ratio of plant hight to basal diameter were surveyed for variance analysis. The results showed that variance coefficient of 6 traits ranged from 15.72% to 89.64% within the family and from 9.30% to 26.73% among families. The maximum values of plant hight, basal diameter and total branch length among families were 1.37 to 2.57 times of the minimum values (p<0.05). The correlation analysis indicated that high degree of positive correlations existed among plant hight, basal diameter and total branch length. The frequency distribution analysis showed that normal distribution existed in plant hight, basal diameter and total branch length. There was significant difference of growth trait among families and individuals, which indicated that variation of growth trait in H. pandurifolia were abundant.关键词
