Chemical composition of the essential oil extracted by hydrodistillation (Clevenger
apparatus) from some aerial parts (ripe and unripe fruit) of Pistacia Atlantica
(Anacardiaceae) which are widely spread throughout the countries of the Mediterranea
n
Sea and have been occupying a good part of the mount of Syria was determined by Gas
Chromatography-Mass Spectrometer GC/MS.
The results of analyzing showed that the oil consist of five compounds in ripe and
unripe fruit, and it was found that the component with the highest ratio in both samples is
the same 2-methylbutanal and its ratio 95.713% in the ripe fruit and 94.138% in the unripe
fruit.
The results of this study also show that the essential oil components of the Syrian
Pistacia fruits are completely different from those in different environments due to the
different types of pistacia species which have been studied and the different environmental
conditions in which this plant grows.
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.
Pistacia palaestina is one of endemic species woodlands in
mediterraneans areas and Syria , Wich is spreading principally in
Quercus ssp and pinus ssp comminuties. Those communities of
woodlands are suffered by multiple conditions as deforestation
, so
these woodlands are accelerated to developing toward surbland
(maquis).
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 choloroformic extract of Pistacia Lentiscus L. is separated and
resulted in the isolation of one compound Abietadiene.
The structure of the compound was detrmained by spectroscopic
technique :
[ IR,1H-NMR,13C-NMR, DEPT(90º) , DEPT(135º), HMQC
,
HETCOR, 1H-1H COSY, HMBC, Mass. ]
The chill hour requirements of female and male trees of Pistacia atlantica,
Pistacia palaestina and Pistacia khinjuk have been examined. This was carried
out through putting the studied cuttings in cool chamber for different perriods
of temperatur
es of 2 °C (550, 650, 750, 850, 950, and 1050 hours). The cuttings,
later on, were moved into growth chamber which offers temperature, moisture
and light similar to that available at the time of flowering season naturally.
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.
