Primary research on the chemical constituents of Laportea violacea Gagnep;

Life table of Tetranychus urticae feeding on grape leaf in laboratory;

In Vitro Regenerating System of Vitis rotundifolia cv.‘Alachua’ with Its Petioles;

The identification of hybrids derived from Vitis rotundifolia×Vitis vinifera cultivar was carried out using RAPD techniques during seedling stage.

Research on the inducement of resveratrol in grapevine leaves by ultraviolet;

Grapevine leaves were treated with fosetyl-Al and UV radiation to investigate the induction of stilbenic compounds so that the phytoalexin response was confirmed, detected by resveratrol production.

The concentration of glycine betaine,proline and trigonelline in grape leaves is close relative to the ability of grapes’ anti-stress.

A method was established for determining the five stlibenes simultaneously,including resveratrol,piceid,ε-viniferin,δ-viniferin,pterostilbene in grape leaves by high performance liquid chromatography.

In this experiment ,fresh grape leaves are chosen as materials, SDS,CTAB and phenol/ccl4 are used to extract total RNA, to eliminate pollution from polysaccharide etc.

Morphology and development of adaxial stomata on tooth tips of grape leaves were observed with light microscope and scanning electron microscope.
