Abstract
This study investigated the different size determining rootstocks (MM.106 and M.26) reactions with two different apple cultivars (Crispin and Granny Smith) and their effect on vegetative growth in Chencha, Southern Ethiopia. The used research design was a complete randomized block design in three replicates. Features measured during the design included: plant height, trunk growth, inter-node length, canopy width and number of branches. Results showed that, Crispin on MM.106 rootstock had the most mean shoot length current year (34.28 cm), tree height (112.24 cm), trunk cross sectional (19.78 cm2 ) and number of branches (8) compared to Granny Smith ( 23.19cm), (87cm), (11.12 cm2 ) and (6) respectively. The shoot growth of Crispin on M.26 (18.36cm), height (78.26cm), trunk cross sectional area (9.42 cm2 ) and branch (4) in comparison to Granny Smith (14.06cm), (62.67cm) (7.26cm2 ) and (3) respectively was also high. The most inter-node length current year was recorded for Crispin on MM.106 (2.98cm), on M.26 (0.67) while Granny Smith on both MM.106 and M.26 recorded least (1.64cm) and (0.47cm) respectively. Similarly the most canopy width cultivar was registered for Crispin on MM.106 (98.24cm) on M.26 (47.12cm) whereas Granny Smith (65. 64 cm) and (41.45 cm) was the least. This study showed that, all vegetative growth parameters was higher on MM.106 than on M.26. On basis of the results, among experimented rootstocks and cultivars, Crispin on MM.106 rootstock is the proper compound to achieve the largest vegetative growth under the naturally occurring low soil pH (4.8) of Chencha (tolola) district.
