This study was conducted for two successive seasons 2010 and 2011 in the
vine nursery in the governorate of Homs/Syria to evaluate the degree of
grafting success between the two partners to create graft combinations in early
stage of grafting and
to select the most compatible rootstock for our local
studied cultivars. Three grapevines of local cultivars (Halawani, Baladi and
Bayadi) were grafted on four different American rootstocks (Ru140, B41,
Fercal and SO4) using bench grafting by omega machine.
This experiment was carried out during 2009 and 2010 seasons in fields
cultivated with 10 years of Dan and Nebaly cultivars of olive trees in province
of Damascus to study the effect of foliar spray of to one of nitrogen (N), boron
(B) and zinc (Z
) on the leaf area, shoot length, number of flowers, leaves
content of mineral elements, fertilization. These elements were sprayed
individually or combined together four times during the growing season as
follows: nitrogen (5 g/l), boric acid (2g /l), zinc sulfate (2g/ l), nitrogen + boric
acid, nitrogen + zinc sulfate, Boric acid + Zinc sulfate, and nitrogen + boric acid
+ zinc sulphate) at the same rates in single spray.
The compatibility between the varieties and the
percentage of budding success and the vigor and vegetative growth of these
varieties were studied. The plants growth was monitored and all the required
readings were taken from the beginning of buddi
ng at the end of summer until
the end of the next growth season.
