Karyotype analysis of diploid oat germplasm introduced from Canada [PDF]
The chromosome karyotype of three diploid oat species was studied with squash method. The results showed that the karyotype formula of Avena strigosa was 2 n =2 x = 14 = 10 m + 4 sm(2SAT),with metacentric and submetacentric chromosomes,1 pair of ...

采用野外调查与室内分析相结合的方法,研究名山地区稻田植茶后土壤团聚体水稳性变化特征及其影响因素。结果表明:稻田及植茶后的土壤水稳性团聚体含量在各粒径及土层间表现不同,稻田、茶园5年和10年土壤水稳性团聚体含量总体上随着粒径的减小呈先降低后上升的趋势,茶园15年水稳性团聚体含量则随着粒径的减小逐渐增加。从不同土层来看,在0—20,20—40 cm土层中,随着稻田植茶年限的增加,土壤团聚体含量以>2 mm粒径团聚体为主转变为以<0.25 mm粒径团聚体为主,而在40—60 cm土层中,总体上<0.25 ...
