蒙古栎无性系种子园花量变异及空间分布
Flower Quantity Variation and Spatial Distribution of Clones in Quercus mongolica Seed Orchard
摘要
Abstract
The spatial distribution of female and male flowers of Quercus mongolica was investigated and analyzed in Quercus mongolica clonal seed orchard in Jinshan Forest Farm of Jilin Forest Industry Group Linjiang Forestry Co.,Ltd.The results showed that there was significant difference between the number of standard twigs per plant and the number standard twigs per clone.The number of male inflorescence,the number of female flower,the total number of male inflorescence and the total number of female flower of twig were significantly different among clones.According to the number of female and male flowers,the clones were clustered into multi-flowered groups,intermediate groups and few-flowered groups.In Quercus mongolica seed orchards,the difference between male and female flower in upper and lower canopy was significant.The ratio of flower number to the upper and lower layers of the canopy average was 1 ∶ 0.27.It showed that the majority of male and female flower were distributed in the upper canopy.The average ratio of male flower number in different direction of canopy(east,west,south,north)was 1 ∶ 0.89 ∶ 0.92 ∶ 0.72,the average ratio of female flower amount in different direction of canopy was 1 ∶ 0.83 ∶ 0.87 ∶ 0.72.关键词
