Abstract

In order to discuss standards for sorting and growth patterns of Lycium barbarum seedlings，the standard for grading Lycium barbarum seedlings was studied using a principal component analysis and the mean standard deviation. Categories of basal diameter and quantity of side roots were determined as possible quality indexes for seedling grading. Using the survival rate，branch length，branch growth rate and number of secondary branches of growth targets of different seedling grades was also established. Results showed that for first-grade seedlings（Ⅰ），basal diameter was 8.0 mm with 11 side roots；second-grade seedlings （Ⅱ） had a basal diameter of 4.5 - 8.0 mm and 3 － 11 side roots；while third-grade seedlings（Ⅲ） had a basal diameter 4.5 mm and 3 side roots. After two months of planting out，the survival rates of I and Ⅱ were ＞ 95.0%. Compared to Ⅲ，increases for Ⅰwere：branch length （17.8%），branch growth rate（25.6%），and the number of secondary branches for Ⅰ（187.5%）；whereas increases for Ⅱ compared to Ⅲ were：6.5%（branch length），4.9% （branch growth rate），and 25.0% （number of secondary branches for I）. Also，the number of secondary branches of Ⅰwere significantly higher （P0.01） than Ⅱ and Ⅲ.［Ch，5 tab. 11 ref.］
