Two species of the Cucurbitaceae were collected and studied during Fep.2013 and June 2014 in Lattakia. As a result of this study, Ecballium elaterium was recorded on the Syrian coast ,while the other was´t.
In this research where they were given an
accurate scientific description The research also included examining the pollens,the result of which was that the pollens were similar in shape of the elliptic, prolate and sometimes globular shape. Trilinear growth holes were proved to exist in both species ,the fact that had made proof the correspondence between them. this Paleonological study is considered to be the first to study such these two species. It involved an anatomical additional study acted upon the above-mentioned. Two species where we examind thin cross section of the root, stem ,leaf neckband and the leaf.
The aim of this research was to investigate the changes of vegetation and
regeneration of plant species in Kassab forests after 1991 fire. The study area is
located in the North western part of Syria in the middle of Al-Baier and Al-
Bassit forest
s to the North of Latakia. Thirty five plant surveys (Relevé) were
carried out in the study area during 2009 according to Braun-Blanquet method
included the burned area and the nearby locations of non-burned forest. By
comparing the plant surveys (Relevé), results showed good regeneration of
most plant species that were in the study area before the fire. Three forms of
vegetation were distinguished in the study area: 1 - The areas where dominance
is shared between Pinus brutia Ten. and Quercus cerris L. subsp. pseudocerris
(Boiss.) Chalabi. 2 - Areas dominated by Pinus brutia Ten. with accompanying
species from Eu-Mediterranean zone and supra Mediterranean zone. 3 – Areas
where Pinus brutia Ten. and Quercus cerris L. subsp. pseudocerris (Boiss.)
Chalabi are partly or completely absent, and dominated by shrubs and grass
species.
This study was performed on three types of the genus Fumaria. The
measurements were taken from the various parts of the flower
petals, Sepals , the stamina and fruits. Also, an anatomical study
was conducted of the root and stem. The shape and dia
meter of
pollen grains, the diameter of germination hole and the number of
total pollen grains were studied. It was observed that the longest
flowers and fruits in the specie F.capreolata.
This study was performed the existence of the species Datura innoxia Mill. in the Syrian
flora. Also the morphological study results showed that the plant is a gray greenish herb,
its stem is erect. Leaves are simple, alternated, oval, its angle is
turbinated to the out. The
root is sphenoid.
The flower is regular. The fruit is capsule, and the seed is splay, have an excrescence.
The palynological study showed that the pollens are ellipticity, triad of germination lines.
Whereas, the anatomical study showed that the form of carrier packing take quadric side
type.
A comparison was made between Papaver and Malva plants in Aljaouba area between the grown plants on the roadside (0-3 m) , and also50 m far nearly exposure to the pollution . The study in volves a comparison analyses for the concentrations of some he
avy metals in the tissues of two studied plants ,during the period April-July 2010 , in order to show the effect of the increased number of vehicles on the concentrations of these metals . The analyses showed that a change of the mineral content of some heavy metals in the tissues of the leaf, according to its far and near to the road , where concentrations of Pb , Cu , Fe , were decreased in various rates , according to the faring stepwise from the road . It also noticed an increasing inthe concentrations of these elements by increasing number of vehicles . The results showed also that plants , which are growing on the roadside , are affected by the pollutants emitted by exhausts , where plant length , leaf weight , leaf area , water content were decreased . The Pollutionalso affected the reproduction and production structures , where the number of flowers and its weight , distances of petals , number of stamens , number of fruits and their weight were decreased .
