50. Performance of different olive cultivars under time of grafting
Abstract
The experiment “performance of different olive cultivars under time of grafting” was laid out in
randomized complete block design with two factors factorial arrangement replicated three times.
Three olive cultivars, i.e., Kalamata, Arbequina and FS-17 were used as scion on wild olive root
stock with three different grafting times i.e. Early June, Mid July and late August. Different
times of grafting significantly affected all of the parameters studied, except number of leaves.
Significant differences were observed among cultivars for all variables studied, except for
number of sprouts per grafting. In case of time of grafting, maximum sprouting percentage
(73.8%), number of sprouts (4.1), shoot length (12.23 cm), shoot diameter (2.56 mm), leaves per
shoot (17.05) and minimum days to sprouting (26.6) were recorded in olive plants grafted in
July. The plants grafted in June took higher days to sprout (32.7), minimum sprouting percentage
(67.7%) and shoot diameter (1.97 mm), whereas plants grafted in August attained minimum
shoot length (8.83cm). In case of performance of different cultivars, maximum sprouting
percentage (71.8%), shoot length (11.48cm), Leaves per shoot (17.43) and lower days to
sprouting (28.5), and shoot diameter (2.06mm) were attained by cultivars Arbequina, while
Kalamata showed lower sprouting percentage (62.7%), leaves per shoot (12.80) and maximum
days to sprouting (30.1). It is concluded that July is the optimum time for grafting of olive
cultivars, specifically Arbequina.
