Influence of rootstocks on fruit maturity and quality of 'Jonagold' apples.

The effects of 13 rootstocks on fruit quality and maturity of the apple cultivar Jonagold were investigated in Poland in 1997/98 and 1998/99. Postharvest ripening was studied at room temperature. Fruits were also stored for up to 6 months at 0 deg C. Fruits from trees on P60 and 62-396 started the climacteric 5-7 days earlier than fruits from PB-4. Fruits were more yellow at harvest from trees on P60, 62-396 and M.26; fruit colour was weak on PB-4 and fruits from these trees coloured most slowly during storage. Leaf Ca was highest for trees on B146 and P60. Fruitlets and fruits from trees on B146 and PB-4 generally had a high Ca concentration. In the second year of study, rootstock had a considerable effect on maturation and storage ability. Fruits from trees on B146 had the lowest respiration rates and ethylene production after 2 and 4 months' storage but not after 6 months.
