Radiobiological method of studying sustainability of grafted grape Georgian varieties towards extreme factors

Abstract

Prognosis of the grape endemic varieties sustainability represents an important scientific-practical task for Georgia. This is conditioned by the circumstances that more than 500 endemic varieties of grape grow in different climatic zones of Georgia. Especially noteworthy is problem of sustainability towards high temperatures of endemic grape grafting with regard to expected global-climatic processes. The present work deals with the radiobiological method of studying sustainability of grafted grape endemic varieties based on several radiobiological and radiological methods. In particular, using the primary fluorescence of grape tissues by the high quality accuracy can be determined structural-functional condition of the grafted grape accretion zone. In addition, by examining the xylem transport of graft, it’s possible to test stability of grape in condition of optimum and extreme temperature regime. Overall, conducted research allows complex diagnostics of accretion quality of plant transplants and their sustainability level prediction towards unfavorable envi- ronmental factors.
