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.
Highlights
Olive has high demand and is a need ofOlea is one of the 30 genera belongs to modern day as oil crop
It will help to find out the incompatibilities between the possible rootstock–scion combinations, to quantify the quality of the grafting, to study the possible transfer of characters, and even to improve the tolerance of the resulting plant to adverse conditions of soil, climate and parasites. keeping in view these future prospects of Olive and the problems that growers are facing with producing true to type olive plants of different varieties, the present research was initiated to study the impact of time of grafting on different olive cultivars
Materials and methods The experiment was conducted at Agricultural Research Institute Tarnab Peshawar, Pakistan during 2014 under the project “Research, development and Promotion of Olive in Khyber Pakhutnkhwa, Pakistan”
Summary
Olea is one of the 30 genera belongs to modern day as oil crop. The modern family Oleaceae and the most famous specie of this genera is Olive (Olea europaea L.) with origin of Syria or Lebanon [1]. Olive having a lot of problems by propagation through other means like seed, the daughter plants are not true to type, there fruit quality is much inferior and of no use, while propagation through cutting there is 30-50% under much control condition in few cultivars [8]. The development of this technique for olive tree varieties selected clonally will allow to develop technology for other the fruit trees like analyzing the rootstock– scion influence on the biological characteristics of the resulting plant development, vigor, productivity, quality of the fruit and oil production. Stoddard and McCully, [12] found that leaves and buds near the graft union are an important source of xylem-inducing stimuli, and an auxin gradient is necessary for vascular tissue regeneration
