RESPONSE TO DIFFERENT TIMING FACTORS BY WILD OLIVE SEEDLINGS WHILE USING VARIOUS GRAFTING METHODS
Abstract
An experiment to study “the response of different timing factors on wild olive seedlings by using various grafting methods” was conducted at Pakistan Oilseed Development Board (PODB), Khyber Pakhtunkhwa research facility at Tarnab, Peshawar, during the year 2010. Three grafting methods i.e. side graft, tongue graft and cleft graft of cultivar Coratina were used as a scion for grafting on wild olive seedling with three time intervals i.e. 1st May, 1st June, and 1st July under control condition. Each replication was containing 27 seedlings for grafting in each grafting method and time interval. The experiment was laid out in Randomized Complete Block design with two factorial arrangement replicated three times. The research revealed significantly differences for days to sprouting, Number of leaves graft-1 , number of shoot graft-1 , shoot length graft-1 and shoot diameter graft-1 for both the times and grafting methods factors. Results showed that maximum number of shoots (1.67), shoot length (3.57) and shoot diameter (7.27) were recorded in side grafting methods, while maximum number of leaves (25.0) was recorded in tongue grafting and early sprouting (10.7) was noted in cleft grafting. Minimum number of leaves (13.0), number of shoots (1.0), shoots length (1.73) and shoot diameter (2.43) were recorded in cleft grafting method, while late sprouting (2.03) was noted in tongue grafting. During timing factor maximum number of leaves (25.3) and shoot length (2.60) was recorded when grafting done in the month of May, while maximum number of shoots (1.67) and late sprouting (15.3) was observed during the month of July and maximum shoot diameter (5.43) was recorded when grafting done in the month of June. Minimum number of shoots (1.33), shoot diameter (4.83) and late sprouting (18.0) were recorded during the month of May, while minimum number of leaves (16.7) was noted in July and minimum shoot length (2.43) was observed in the month of June. It was concluded that for successful grafting side method is recommended in the month of May and June.
