柿树种质资源叶片形态多样性研究及聚类分析
Research and Cluster Analysis of Leaf Shape Diversity of Persimmon Germplasm Resources
摘要
Abstract
Base on 12 persimmon germplasms with local characteristics in Huixian,the leaf shape diversity was investigated. The results showed that there were a large number of variations of leaf characters among the different persimmon resources; the variation range of leaf length was from 10. 2 cm to 15. 1 cm with the coefficient from 7. 1% to 14. 5%,the variation range of leaf width was from 6. 3 cm to 9. 8 cm with the coefficient from 6. 7% to 15. 8%,and the variation range of leaf area was from 47. 2 cm2 to 110. 6 cm2 with the coefficient from 12. 9% to 30. 6%. The variation among different persimmon germplasms reached a significant level with F value of five shape indexes of all over 18. 759 — 53. 553. In cluster analysis,based on the data of leaf index, 12 persimmon species could be divided into four categories. Four species (Mantianhong, Tu Shengchutdir. Niu Xinshi and Bian Yichutou) belonging to class I ,3 species(Shui Botie,Chu Tou and Shui Shi) belonging to class II,4 species (Mo Panshi,Bian Ke,Shi Shenglianhua and Jian Shi) belonging to class III and one species (Tu Shengbianke) belonging to class IV. This indicated a abundant genetic diversity in persimmon in Huixian ditch and provided theoretical basis for germplasm utilization in the future.关键词
