Abstract
Seedlings and cuttings taken from single M. integrifolia (246) and M. tetraphylla (Gower) trees were used as rootstocks.
Scions of H2, Own Choice, HY, 246, 333, 344, 508 and 660 were grafted on seedlings and cuttings of the four types of rootstocks.
After seven years trees on seedling rootstock suffered minimum wind damage while 20% of trees on 246 clonal rootstock and 57% on Gower clonal rootstock were uprooted because of strong winds.
Scions of H2, Own Choice, HY, 246, 333, 344, 508 and 660 were grafted on seedlings and cuttings of the four types of rootstocks.
After seven years trees on seedling rootstock suffered minimum wind damage while 20% of trees on 246 clonal rootstock and 57% on Gower clonal rootstock were uprooted because of strong winds.
Early growth was greater in scions on seedling rootstocks although incremental growth was higher in 1991 in 246 clonal.
Precocity was related to vigour.
Kernel recovery and percentage of nuts that float in tap water (grade 1 kernels) were not affected by rootstock type.
Scion type significantly (P<0.05) affected all parameters measured.
After two years cropping 344 showed consistent good performance while HY showed poor growth and quality.
