This study indicated the presence of different shapes and sizes of grains starch in
Milky liquid (latex) for 10 speciec of genus euphorbia these:
, E.geniculata , E.pilulifera , E. serpens, E.prostrata , E. thamnoides
E. paralias , E. terracina, E
. aleppica , E. peplus, , E. helioscopia
which varied between: (Rod) ,(Spindle), (Slightly osteoid), (Osteoid), (Dumb-blle),
(Ostcoid branched), intermediate forms with indentation and accessories , pollen grains
werw: spherical, or oval-shaped 3-colporate, It is of the Euphorbia hirta- type , and
Ornamentation Tectum coarsely reticulate in (E.geniculata) only, and fine reticulate in the
others species , and size of a Pollen grains differed between species .The largest size
found in E. geniculata (P= 46.21mμ , E = 44.68 mμ)For spherical shape and (P =42.56 =
m μ, E =37.54 mμ )For elongated shape.The smallest size found in E.pilulifera (P=16mμ ,
E 15.62 =mμ)For spherical shape and (P = 17.68 m μ, E13 .12 =mμ ) For elongated
shape.
The samples of bee pollen were collected from inside and outside
the honey beehives of apiaries situated in five different locations of
Latakia; Al-Qardahah, Al-Haffeh, Jableh, Latakia city and Eastern
Entryway to Latakia during the autumn in 2014
. The
concentrations of three heavy metals, zinc (Zn), lead (Pb), cadmium
(Cd) were determined in pollen by using atomic absorption.
A morphological , anatomical and chemical study was carried out on Salvia viridis
L. (Lamiaceae) . The results showed presence of two types of trichomes :
- Glandular hairs with four or eight celled globular heads or with oval heads .
- Eglandular
hairs which are unicellular or multicellular , in addition to presence of
candle shaped eglandular hairs .
The palynological study revealed that the pollen grains were prolate and they had six
germination lines , exine appeared reticulate .
The extraction of volatile oils have been done by dry evaporation using GC/MS
technique , chromatographic analysis of these extracts have showed the presence of
complex of carboxylic acids , hydrocarbons , terpenes , esters and aldehydes .
The results of studying the morphological characteristics of the flower, fruit,
pollen grains, and seeds between some of Hypericum genus species, show that
there are relevant morphological differences among the studied species, which
can be considered as taxonomical criteria for distinguishing the studied species
of Hypericum genus from each other.
