The Tsitska is cultivated in the west part of Georgia. Comparing the healthy and diseased grapevine leaves physiological concentrations of stilbenoids, in the infected grapevine leaves it is established following stress-metabolite stilbenoids: trans-resveratrol and ε- viniferin. The stress-metabolite stilbenoids in the conditions of the disease with Downy mildew is a scientific novelty for the vine leave Tsutska variety. The results of the research are important for determination the correlation of the vine immunity with the phytoalexins-stilbenoids.enფიტოალექსინი-სტილბენოიდებიციცკაჭრაქიphytoalexin-stilbenoidsTsitskaDowny mildewtext::journal::journal article::research article
