Research of Seedling Quality Grading of Dendrobium nobile
摘要
Abstract
Objective: To establish the seedling quality grading standard of Dendrobium nobile. Methods: Height, stem thickness and stem nodes of seedlings(test-tube seedling and cutting seedling) from Chishui city Guizhou province were tested. Through statistical analysis, the key indicators for seedling quality grading were defined. Results: Height and the number of cluster were the primary indicator of test-tube seedling; Height and the number of buds were the primary indicator of cutting seedling. Conclusion; The grade test-tube seedling quality of each grade should reach the following requirements; for the first grade seedlings height ≥17cm, the numbers of cluster≥3; For the second seedling height 11 ~ 17cm, the numbers of cluster ≥2. The grade cutting seedling requires the first grade seedlings height ≥12cm, the numbers of buds ≥3 ; The second grade seedling height 6 ~ 12cm, the numbers of cluster≥2. Seedlings those can hot reach the second grade requirements are defined as unqualified seedlings.关键词
