摘要
采用苗圃试验对25个木麻黄无性系苗期的苗高、地径、保存率和叶绿素总量4个生长性状进行比较,然后进行综合评价。通过苗期选择筛选出5个较适应贫瘠土壤的优良无性系。
In a nursery experiment, the 4 traits of seedling growth, including height, diameter at ground level, survival percentage and total content of chlorophyl at 24 months after transplanting, were compared and compositive evaluation was conducted among 25 casuarina clones. As a result, the 5 superior clones suitable to nutrient - short soil were screened out, based on the 4 traits of casuarina clone seedlings.
