Assessment of vegetative organ structure difference and their correlations among cultivars of Brassica campesttris ssp.chinensis var.rosularis
摘要
Abstract
Anatomical structure and main agronomic characters of eight cultivars in wuta-cai (Brassica campesttris ssp. Chinensis var. Rosularis) were observed.counted and analysed. The results indicated that the thickness of cuticle and mesophyll tissue.and the size of intercellular space showed some differences among these cultivars. The numbers and diameters of vessel in the petioles had higher variation among the eight cultivars (with coefficient of variation 33. 9% and 36. 2 %, respectively), while the number of vascular bundle and their diameters were lower(with coefficient of variation 23. 8% and 25. 2% ,respectively). There were distinct differences in number of leaves and weight of lamina per plan(with coefficient of variation 97.16% and 71. 30% ,respectively) ,but the differences of the maximum spread width and weight per fresh plant were no evident(with coefficient of variation 47. 87%). Eight cultivars were divided into three groups by cluster analysis at 6. 87 of rescaled distance,which were W2 and W11 ,W23,W39,W56, W57 and W61 ,and W38,each group standed for a certain kind of cultivar character. Correlation analysis between 23 indices indicated that 10 index-pairs were significant positive correlated and three of them were significant negative correlated,taking up 3. 95% and 1. 19% of total index-pairs,respectively. Judging by integrated estimate,the cultivar W38 had the highest drought resistance and that of W11 was the lowest .关键词
