In 1998-1999 the effect of six rootstocks - P 14, M.26, P 60, P 2,
M.9 and P 22 - on some qualities of ‘Jonagold’ and ‘Melrose’ apples,
after harvest and after cold storage, was studied at Babtai (Central
Lithuania). The largest ‘Jonagold’ fruits were obtained from trees on P 14
rootstock and those of ‘Melrose’ on M.9. There were no significant
differences owing to rootstock in fruit coloration. The maturity index
indicated that ‘Jonagold’ apples were more mature from trees on P 60 or
M.9 and ‘Melrose’ from trees on P 22 or M.9. In general, P 14, M.26, and P
2 induced later ripening of apples. ‘Jonagold’ fruits from trees on
P 14 and ‘Melrose’ fruits from trees on P 22 were firmer at harvest and
retained higher firmness during storage. Dwarfing rootstocks M.9, P 22,
and P 2 promoted a higher content of soluble solids in ‘Melrose’ fruits.
‘Jonagold’ fruits from trees on P 14 and M.9 and ‘Melrose’ fruits from
trees on M.26 and P 60 showed the best storage capacity.
