引种墨西哥柏幼苗越冬情况及苗高生长节律初探
Annual Height Growth Dynamics and Overwintering Survival Situation of Cupressus lusitanica Seedling
摘要
Abstract
[Objective] In order to study overwintering survival rate of Cupressus lusitanica 1 year seedlings under the natural state of overwintering survival rate and the seedling height growth characteristics in Nanjing.[Method] Overwintering survival rate and height of Cupressus lusitanica 1 year seedlings were observed one year in Nanjing Liuhe District.[Result] Overwintering survival rates of Cupressus lusitanica 1 year seedlings had significant difference.Among them the seedling survival rate of D5 provenance was highest,more than 90%.The seedling survival rate of D8 provenance was lowest.The growth time and trends of the seedling were basically identical to 10 provenances.The growth of the seedling height presented a dynamic "slow-fast-slow" general rhythm.[Conclusion] Through this experiment,we know seedling height growth of 10 provenance of Cupressus lusitanica 1 year seedlings in Nanjing mainly follow Logistic rules,but high average seedlings growth of different provenance had significant difference.关键词
