Abstract:
Objective: To study the quality of Acanthopanax senticosus seedlings,develop grading standards and optimize the best analytical method. Method: Observing and measuring the plant height,diameter,leaf area,root length,chlorophyll content and other main agronomic traits of A. senticosus seedlings from different habitats(Baoqing,Qitaihe,Dongfanghong,Yilan,Acheng,Raohe Linkou and Yabuli) in each year. K-cluster grading method,principal component evaluation factor K-cluster analysis method,standard deviation method for grading,three classification methods were evaluated with different levels of seedling survival rate as indicators. Result: The direct K-cluster analysis method was used to determine the quality of A. senticosus seedlings as the best method. The seedlings of A. senticosus were divided into 3 grades,among in the first level the seedling height is ≥ 13 cm,the stem diameter is ≥ 0.37 cm,the root length is ≥ 8 cm,the leaf area is ≥ 28 cm2,the chlorophyll content is ≤ 31,the main origin is Baoqing,Qitaihe area. In the second level the seedling height is 8-13 cm,the stem diameter is 0.30-0.37 cm,the root length is 6-8 cm,the leaf area is 13-28 cm2,the chlorophyll content is 31-32,and the main origin is Acheng,Dongfanghong,Raohe area. In the third level the seedling height is 5-8 cm,the stem diameter is 0.26-0.30 cm,the root length is 5-6 cm,the leaf area is 5-13 cm2,the chlorophyll content is 32-38,and the main origin is Yabuli,Yilan and Linkou. Conclusion: In this experiment,the quality grading standards of A. senticosus seedlings were preliminarily established,Baoqing and Qitaihe can be used as a high-quality production area for breeding seeds in the Heilongjiang province.which provided the basis for quality evaluation of A. senticosus seedling planting and artificial cultivation.
