The research studied the compatibility of grafting on the pistachio
variety of Nab AL Jamal with three rootstocks (P. vera, P.
Atlantica and P. Khinjuk). This research was implemented in the
nursery of the agricultural department in Hama. The seed
ling
rootstocks were budded in plastic bags at the beginning of June by
T-budding.
The research studied the compatibility of grafting on the pistachio
variety of Ashouri with three rootstocks (P. vera, P. Atlantica and
P. Khinjuk). This research was implemented in the nursery of the
agricultural department in Hama. The seedling
rootstocks were
budded in plastic bags at the beginning of June by T-budding. The results demonstrated that the variety of Ashouri which budded on the Ashouri and P. Khinjuk rootstocks excelled at the p. Atlantica rootstocks, The best average of succeeded graft of Ashouri variety budded on the Ashouri and P. Khinjuk rootstocks reached (73, 69.5 %). While the growth of p. Atlantica and P. Khinjuk rootstocks were stronger than Ashouri rootstocks. The length of Ashouri variety which budded on P. Atlantica and P. Khinjuk rootstocks was (47.36, 49.88 cm), and the diameter was (5.59, 5.67 mm).
Winter chilling requirements are critical for flowering and fruiting of many
fruit species, with evidence that pistachio has been adversely affected by warm
winter, so that estimating chilling and heat requirements is crucial for
identifying appro
priate cultivars for given site. In our study, different levels of
chilling hours were applied (500-600-700-800-900-1000-1100-1200-1300-1400 h).
The research trial was carried out at University of California, Davis,
Agriculture and Natural Resources, Cooperative Extension–Kearney
Agricultural Center (KAC).
Part of the scientific work in the laboratory started from November 1, 2001
through
out the end of February 2002. This trial was conducted using Pistacia
vera; the female variety ‘Kerman’ and its pollinator, variety ‘Peters’;… both
are grafted on the rootstock UCB1.
