Показатели фотосинтетической деятельности столовых сортов винограда при прививке на различные подвои

Abstract

Researches on photosynthetic activity of table grape varieties, introduced in Republic of Moldova: Loose Perlette, Summer Muscat, Monukka and Italia, grafted on different rootstocks were carried out. It was shown, that at grafted scion varieties on high vigour stocks 44-53M and B×R 5BB the Leaf Area Surface, Leaf Area Duration, Dry Plant Biomass and absorbed of Photosynthetic Activity Radiation coefficient increases. At a grafted on moderate vigour stocks B×R SO4 and R×R 101-14 increase of Unit Leaf Rate and Crop Growth Rate is observed.
