The effect of scion-rootstock combinations of Crimean native varieties on the mechanical strength of intergrowth of grafted components
The article gives an assessment of compatibility of promising scion-rootstock grape combinations based on the analysis of specific mechanical strength of intergrowth of the rootstock with the scion. For the experiment, five Crimean native grape varieties (‘Gevat Kara’, ‘Ekim Kara’, ‘Kefesiya’, ‘Sary Pandas’, ‘Kokur Belyi’), grafted on recognized rootstocks (‘Berlandieri × Riparia Kober 5 BB’, ‘Berlandieri × Riparia СО4’, ‘Riparia × Rupestris 101-14’) were used. It was established that the mechanical strength of intergrowth of grafted components varies depending on the combinations of rootstock and scion. For reliable assessment of the data obtained, a three-factor analysis of variance was carried out, and a comprehensive assessment of the effect of various factors on the mechanical strength of intergrowth of the studied scion-rootstock combinations was given.
