Abstract

The present study was carried out in the green house of the Experimental Farm of Horticulture Department, Faculty of Agriculture, Benha University, Qalyubia Governorate, Egypt, during two successive seasons of (2013-2014 and 2014-2015).
The aim of this investigation was to study the influence of the two investigated factors i.e., olive cultivars (Kalamata and Dolce) and pre- grafting treatments of olive scions bases by some growth regulatour treatments, just before their possible combinations.The influence was evaluated throught the response of some vegetative growth parameters, determination of leaf chemical constituents, as well as, the anatomical examination of scion-stock union zone.Grafting procedures
1-Preparation of chemlali seedling rootstock: The preparation of Chemlali seedling rootstock was stared during early-to mid- December of years 2013 and 2014 for the 1st and 2nd experimental seasons, respectively. One year old Chemlali olive, healthy and disease free seedlings were chosen, approximately similar in their growth vigour, with suitable stem thickness (more than0.6 cm diameter) measured at 20 cm. height from soil surface.
2-Preparation of scion sticks:
One Kalamata and one Dolce olive trees were selected as a source of scion sticks from each cultivar for cleft grafting on the previously prepared Chemlali rootstock seedlings. The selected Dolce and Kalamata trees were healthy, productive and free of known diseases.
After preparation of scion sticks from each scion cultivar, careful precausions were taken for maintaining the moisture content of the prepared scion sticks during their transportation from the olive orchad at El-khatatba to the Faculty of Agriculture nursery at Moshtohor.
3-Growth regulator treatments:
Prior to the grafting process, growth regulator solutions at the needed concentrations were prepared, and the following eight growth regulator treatments were ready: IBA at 50 and 100 mg/L, Kinetin at 5 and10 mg/L, NAA at 50 and 100 mg/L, IBA at 50 mg/L +Kinetin at 5 mg/L and Tap water (as control).
4-The grafting process:
The grafting process was carried out in mid-February of the years of 2014 and 2015.
a – The Chemlali rootstock seedlings were trimmed and the top was cut-off at 20-25cm from soil surface, then a vertical cut about 5 cm. long is made in the rootstock.
b- A scion stick 10 to 15 cm. long was selected, preferably of the same diameter as the rootstock, then a 2-sided wedge of the same length as the cut in the rootstock was made at the base of the scion.c- The scion base was dipped in one of the growth regulator treatments for fifteen seconds –just before being inserted onto the rootstock, and checked to be sure that cut surfaces are in good contact and the cambial layers are aligned on at least one side.d-The wrap was made in an upward spiral with the end tucked under the final turn and pulled taut.
