This research aims to investigate the effectiveness of anti-bacteria shown by the extracts prepared from
per carps of different types of Punica granatum ( L) ( from the family Punicaceae), which grow in Syria
against Escherichia coli (E.coli) biotype (1), which were resistant to studied antibiotics.
The antioxidant activity of pomegranate juices extracted by two methods
was determined using three methods: β- carotene, Linoleic acid emulsion, and
DiPhenel Picryl Hydrazyl (DPPH). The juice was extracted by separation arils
from fruits and squee
zed using Cyclone machine (T-1), while the second
extraction method included squeezing the whole halve fruit with previous
machine, (T-2). The potential compounds were determined using ethanol in a
comparison with Butylated hydroxyl Anisole (BHA) as reference antioxidant.
There were significant differences (P<0.05) in the antioxidant activity between
the treatments in all measuring methods. The means of antioxidant activity
amounted to 82.66% in T-1, 86.82% in T-2 and 86.98% in BHA. There was
significant relationship between total phenols and antioxidant activity in all
treatments.
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.
Random Amplified Polymorphic DNA (RAPD) was used to evaluate genetic
diversity among 11 Yemeny pomegranate types. Samples were collected in 2004
from three main regions: east, middle and north of the country (Rada, Hada
and Saada). PCR amplificati
on of pomogranate DNA with 30 random primers
generated 1013 bands, 118 of them were polymorphic 11.5%. Results showed
that the genetic diversity within the tested types was limited. Similarity values
ranged between 59 –96 % with a mean of 79 %. Statistical analysis showed
that the types can be divided into two clusters: cluster 1 with Orkobi and
Mellies types found in the Hada region; cluster 2 includes nine types belonging
to the Saada and Radaa regions .High similarity (90–96%) was obtained with
Khazemy, Liessy 1, Liessy 2, Taefi, Ahmer and Balady types. Whereas, some
types could be considerd as separate cultivars due to their high genetic
diversity such as, Orkoby and Mellies (Hada region) in addition to Bohssom,
Sommaty and Liessy 3 in the Saada region.
Study was conducted in five locations as the important areas for
pomegranate cultivation and production in Yemen, during the period (15/1–
15/8/2004). Eight accessions of local pomegranate were used in this study:
Taefi, Orkobi, Mellies–Hada, Khaz
emy, Sommaty, Kodary, Chiny and Mellies–
Raudha in addition to the wild pomegranate type (Socotria). The
morphological characters were determined for leaves, flowers,fruits and seeds.
The chemical analysis for juice was also assessed. Maximum rate for fruit
weight was 527.3 gm for Kodary accession, whereas fruit Juic varied between
49.5–63.2%, while peel / fruit was varied between15% in Taefi and 35.9 % in
Chiny, whereas the peel thickness varied between 1.5–4.2 mm. The Scotria was
found to be evergreen, and flowers around the year. Kazemy accession gave
higher fruits number/tree with rate 246.7. The greatest rate of T.S.S and
Vitamin C were 18.57% and 11.12 mg respectively for Chiny accession, and the
highest content of organic acids in these accessions was 0.54 % for Taefi.
The aim of study was to compare the physicochemical and morphological properties of
Five pomegranate cultivars grown in different region of latakia.
Properties included: fruit fresh weight,number of arils per fruit, peel weight, soluble solids
(TS
S), titratable acidity (TA)vitamin, reducing sugar .
Fruit weight ranged from(336.8 -484.77 g), peel weight of the fruit was recorded from
93,84 to 127,85g, juice weight was( 69,33-151,66 g) and reducing sugars ranged between
(3.64 -12.4 %). total soluble solid ranged from( 14.5- 16.5) % and titratable acidity ranged
between( 0.358- 1.321%)in pomegranate juices.vitamin C content also ranged between
11.5- 14.5 mg\100 ml).
