Abstract:
The present study was carried out in order to test
the effect of grapevine rootstocks root
growth on biomass and leaf nutrition status in extr
eme soil conditions. Own rooted
cuttings of rootstocks Fercal, Teleki Kober 5BB, Ge
orgikon 28 and four new rootstock
hybrids from the breeding program of Georgikon Facu
lty, Hungary (FB01, JB01, Zamor
17 and SZF10) were grown 3 months in pots. The 5 L
pots were filled with a layer of
gravel, high lime content Rendzina soil (pH 8.54) t
opped with a layer of peat-soil mixture
(pH 4.94). The biomass production, shoot, leaf and
root development largely depended on
the rootstocks genotype. The differences among stud
ied rootstocks were significant under
low pH. Correlation was found between the root dry
weight and the aboveground parts.
The ratio between them was strongly influenced by r
ootstocks genotype. Rootstocks had
strong influence on leaf nutrient status.
