Histological structure of hair root and limed skin was separately observed by optical microscope,scanning electron microscope and by tissue section method during different phases of enzymatic dehairing,which could be used to interpret mechanism of action by different depilatory techniques.

69N,The tensilestrength of hair root increased with its diameter enlarged and the increasement rate is that grass>legumes>artemisia.

Effects of different irrigation patterns on the growth of maize root hair.;

The mechanism of root hair development and molecular regulation in plants;

The observation of microstructure showed that seed roots of RM109 had no lateral rootsand root hair was less and shorter, but cv.

Objective To probe the feasibility of PCR-STR typing of hair root without sheath cells with current and redesigned miniSTR amplicon primers.

To elucidate the mechanisms of the toxicity of Al to leguminous plants at initial stages of symbiotic nodulation,the effects of Al on the growth of primary root,root hair deformation(RHD),nodulation of Medicago sativa L.

Effects of low pH on root hair deformation(RHD)and nodulation in Medicago sativa were investigated and corresponded mechanisms was also discussed in present study.

Induction and Culture of Hairy-root by Agrobacteriun rhizogenes in Dendrobium nobile;

In this paper the method of hairy-root produced by Agrobacterium rhizogenes inducement was reviewed, and the new research achievements of plant secondary metabolites produced by hairy-root culture technology was introduced.

There are many methods used in cell culture to improve the secondary metabolite production, such as: screen cell lines, optimize the cell culture conditions, immovable cell culture, use elicitor, hairy-root culture.
