Yundingshan Nature Reserve is situated in the middle part of the Luliang Mountains,Shanxi province.The wild seed plants of Yundingshan Nature Reserve included 926 species,391 genera and 85 families,of which gymnosperms accounted for 6 species,4 genera and 2 families,and angiosperms accounted for 920 species,387 genera,and 83 families(of which dicotyledons included 756 species,311 genera 72 families and monocotyledons included 164 species,76 genera and 11 families).The floristic characteristics of seed plants were diversified and complicated in composition,and were dominated by temperate elements(including 275 temperate genera,accounting for 82.08% of all the genera).Among the floristic elements of species,the temperate elements absolutely dominated,which included 566 species accoun-ting for 62.61%;the second were the endemics to China with 306 species,which were the constructive and dominant forest and shrub species of Yundingshan Nature Reserve.The results showed that higher homogeneity and closer relationship in the floristic elements and vegetation components between Yundingshan Nature Reserve and Pangquangou Nature Reserve,less similarity with Wutai Mountains,and the least similarity with Zhongtiao Mountains.Moreover,Glycine soja being under the national first class protection,and Aconitum smithii,Rhodiola rosea and Codonopsis pilosula being under provincial protection were also found during this study.

The leaves from fifteen populations of Pteroceltis tatarinowii Maxim.in eight provin-ces of China were compared and analyzed by the paraffin method and leaf epidermal maceration.Results showed that there were significant differences between leaf anatomical characteristics of populations,and the palisade tissue cell generally formed two layers.The shapes of the adaxial epidermal cells were polygonal or irregular,while abaxial epidermal cells were irregular.There were many types of anticlinal walls of adaxial surfaces,including flat,round,and shallow and deep wavy.Wavy was the only shape found in anticlinal walls of abaxial surfaces.Distribution of the epidermal hairs in these populations was significantly different,while the types of epidermal hair showed the stabilization in all populations,and the epidermal hair formed floral hoops with cells all around them in most populations.The types of stomatal apparatus in all the populations were irregular,and the stomatal apparatus was only found on the abaxial surface with a random distribution.Characteristics such as size and density of stomatal apparatus were different in these populations.There was a certain correlation between climate factors and the features of leaves from different populations.These results showed that the differences in anatomical structure of leaves from different populations were diverse.Leaf epidermal characteristicssuch as density of stomatal apparatus were also different,while the types of stomatal apparatus and shapes of epidermal hair in different populations showed stabilization,which may be regarded as evidence for the division of the species.

Male sterility and seeding ability of the cytoplasmic male sterility line of leafy mustard(0912A)(Brassica juncea) were evaluated by fertility and floral characters.With 0912A and its maintainer line(0912B) as maternal parents and five typical inbred lines as male pa-rents,ten F1 hybrids were produced to study the effects of male sterile cytoplasm and heterosis.The results showed that the sterility of 0912A was steadily complete,the fertility and sterile plant rate were 100%,and the seed-set was normal.The heterosis of yield-related traits was obvious,but not for the quality traits.Male cytoplasm had a distinct negative effect on weight per plant,but the heterosis of hau cytoplasmic F1 was still significant.The male cytoplasmic effect on hybrid traits varied with different nuclear genetic background,and the negative effect of cytoplasm could be reduced or eliminated by choosing suitable male parents.
