Variation of leaf epidermal trichome density of three meconopsis species with altitude change in Qinghai;

Recently,many genes have been identified to control the initiation and morphogenesis of the trichomes using Arabidops as a model.

,the leaf epidermis have been examined by scanning electron microscopes(SEM) and the optical microscopy(LM) to study the characteristics of stomata,trichomes and dermal cell,et al.

confusa,which are in the genus of Flos Lonicerae were examined by scanning electron microscopes (SEM) to study the characteristics of stomata,trichomes and dermal cell,et al.

Observation of trichome types and development in three species nightshade;

Fruit trichome of the peach(Prunus persia cv.

The author had a detailed observation of trichomes on the surface of various organs of rare and precious plant-"wingfruit" elaeagnus under scanning electron microscopy (SEM) and stereomicroscope.

The results showed that there was very obvious differences in quantity of syoma and epidermal hair and chlorophyll content between varieties.

The leaf epidermises of seventeen species belonging Seriphidium were observed with scanning electron microscope and the leaf surface of these species were founded to have great amounts of banded waxy substances on the outer surface of which there distributed salt grains and great numbers of epidermal hair,thereby presenting distinct exeric structural characteristics.

Observed in the present work were epidermal cells,stomatal apparatues,epidermal hairs,culticular membrane and wax ornamention of upper and lower epidermis.

In this paper,the leaf epidermal hairs of 28 species and varletes of the genus Potentilla in China were observed under microscope and stero microscope.
