  In this research the ploidy variation of microspore-derived plants in Chinese cabbage was investigated.The results showed that regenerated populations from microspore are usually mixed ploidy and the distribution of haploid,diploid,trploid,tetraploid and chimaera is various in each genotype material.Based on the result of chromosome counting,the authenticity of ploidy determination of microspore-derived plants in Chinese cabbage were further evaluated using several different approaches.The accuracy of ploid...

  Laiwu ginger was used to investigate the effect of soil bulk density on the growth,yield and quality of ginger .Three treatments,1.49(CK),1.36(T1) and 1.20(T2)g·cm~ -3 were set in the experiment.The results indicated that the soil of low bulk density,could obviously promote the growth of ginger,and improve yield.The plant height,stem diameter ,branch and leaf number of T2 were higher than CK by 17.9 %,14.0 %,35.2 % and 36.1 % respectively.The fresh weight of root,stem,leaf and rhizome were higher by 43.3 %,...
