The method of vegetative propagation by hard wood cutting is considered of the
most important ones of prevalent and successful in its cultivation to obtain a Punica
Granatum seeding which are genetically uniform.
In this research,it was used three
categories fPunica Granatum
,Municipal,French,Darcoche,where they were taken the hard wood cutting of sound trees
which free of insecticides and fungal infections and bacteria, and divided into groups
which in cluded five deals to know the effect of hormone,stratification,impact,the hard
wood cutting age and its length on rooting.
It was found that the last three tested categories had no hormone effects on rooting.
The soft wood cutting of one year-old overtook the ones of two-years of age,where
they have the largest effect of rooting.The highest precentage of rooting and stronger were
at the length of 30 cm.
Its advised for stratification of the Municipal class befor its cultivation because it
increases the rooting percentage.
Darcoche is easy for rooting, because it roots by ahigh percentage if it had a
stratification or impact by the conditions of continuous wetting before cultivation.
Semi-wooden cuttings of two - jujuba cultivars were vegetitirely propagated
under greenhouse conditions, by using different concentrations of Indole
butyric acid (IBA), at Hanadi Research Station, Lattakia.
The rooting percentage reached 71.3% aft
er two months for the Ziziphus
jujube mill, and 83.3% for the Ziziphus jujube tayan tsizao, when they were
treated with 4000 mg/L of (IBA) for five seconds while the rooting percentage
was zero for the non-treated cuttings (Control) .
هدف هذا البحث إلى إجراء التوصيف المظهري ودراسة درجة القرابة والتباين بين عدد من الطرز المحلية من التوليب (27) وتحديد عددها الصبغي
