This study is aimed at studying the effect of using four species of
bacteria Plant Growth Promotion Rhizobacteria (PGPR) Azotobacter
chroococcum, Rhizobium leguminosarum, Bacillus megaterium and
Frateuriaaurantia on the growth, yield and reducing
the effect of
Cucumber mosaic virus(CMV) on pepper plants in a greenhouse
experiment. The observed growth parameters were: plant height, foliage
fresh weight, root fresh weight, fruit weight in a green house expirment
in Tartous in the season 2016/2017.
This search aims to study the efficiency of using“Biotolerance” as a
fertiliser; by a foliar spry on Pepper seedling. Four varieties were
used (Marcony, California wander, Maroty-7 andRobber). The
results showed that the treatment by the fertilizer resulted in an
increase in growth thorough the plant length increasing.
This research on pepper crop conducted to impact water stress using
three transactions water are: full irrigation (100% from water
requirement), 0.75% of full irrigation, and 60% of full irrigation,
has been designed experiment in a way random sectors full, use a
variety of municipal plant peppers, and used drip irrigation method.
The aim of this study was to test the effeciency of some organic and bio fertilizers in
improving the seeds germination and transplants growth of pepper Capsicum annum L.
local variaty" Qorn Algazal":by using two commercial compounds; organic (Hube
st) and
one bio (EMI) fertilizers. Two experiments were used; the aim of the first was to study the
effect of these fertilizers on germination of seeds in Petri dishes and plastic peatmoss peds.
Whereas the aim of the second experiment was to evaluate the effect of the fertilizers on
the pepper transplants growth that prepared in the 5 * 5 Striopor peatmoss plates placed in
un warmed plastic tunnel.
The results showed that the soaking of pepper seeds in the tested fertilizers, provoked
and the germination increased the seeds, vigor, with a significant performance of the bio
fertilizer.
The results also showed that the treated transplants with the tested fertilizers gave an
increase of the transplants growth ratio (the height, leaves number and foliar surface area,
the dry and wet weight) with a significance superiority of the bio fertilizer.
Several protocols for DNA extraction from leaves of pepper Capsicum annuum
L. were evaluated to detect Begomoviruses. The extraction
methods comparison were based on DNA quantity and quality. The
DNA concentration absorbance for the evaluation of DNA concentration and contamination
were measured using spectrophotometer.
The study was conducted in Jableh during 2012/2013 in plastic green house on sweet
and hot pepper hybrids to study the effect of plant density on growth and productivity.
The hybrid VIGARIO(sweet pepper) and hybrid ERAD (hot pepper)variety were
ap
plied in six treatment and four replication .It was showed that the highest number of
flowers were recorded in VIGARIO variety in space (50x60)cm to amount(18.33)
flower/plant ,while the the highest number of fruits were recorded in space(50x40)cm to
amount(20.98)fruit/plant and the earlest yield (390.6)g/m2and the highest total
(3486)g/m2productivity were found in space (50x40)cm . IRAD hybrid give the highest
number of flower in space (50x40)cm to amount(28.23) flower/plant,while the hieghest
number of fruit were recorded in space (40x60)cm to amount(107.17) fruit/plant and the
highest productivity were found in space(50x40)cm to amount (9485.7)g/m2.
This research work aimed to study the effect of different mixtures of growing media
on pepper seedlings and their ability to withstand transplanting shock.The variety QarnAlgazal
of pepper and five mixtures of growing media were used.The mixtures i
ncluded bitmoss
alone,bitmoss with equal volume of soil or sand,soil and cow manure in a ratio of
1:2,and cow manure with soil and sand in a ratio of 1:1:1.
The experiments were implemented in aplastic green house without heating in the
nursery farm of the faculty of Agriculture,Tishreen University.The completely randomizel
design was adopted with three replications for each treatment and 15 plants for each replication.
The results showed that themedia containing cow manurewere the more effective ingrowth
of sapling as represteded by the increased hieght of sapling, number and area of
leafs,fresh weight of both biomass and roots of sapling.The effect was very clear in the
media containing cow manure and soil in the ratio of 1:2.
This study was conducted in the village of Almetrkyah located in the southern
coastal plain of Lattakia city during 2014. In order to study the effect of Cucumber mosaic
virus on growth and development of two varieties of peppers, hybrid ESTAR F1 H
(sweet
pepper) and Demer(spicy pepper). This study included eight treatments, four treatments
for each variety. Plants were mechanically inoculated in three different stages, preflowering
bloom, flowering andpost-flowering stages each beside its non-inoculated
control. The result should that, the appearance of Cucumber mosaic virus symptoms on
infected sweet hybrid, was within four days before its appearance on inoculated spicy
variety,symptoms were leaf crinkle, leaf deformation, yellow patches and plant stunting.
Inoculated plants showed reduction in number of leaves, number of branches and yield.
Plants in pre flowering bloom stage were more effected by virus infection in both
varieties. Meannumber of leaves per plant of ESTAR F1 H hybrid were 130 in pre
flowering bloom stage compared with 170 leaf/plant in the control treatment. Mean
number of branches per plant of ESTAR F1 H hybrid were 43,4 branch/plant in pre
flowering bloom stage compared with 56,7branch/plant in the control treatment. Total
pepper production per plant was 700,8g in infected plants in preflowering bloom stage
compared with 1267,5g/plant in ESTAR F1 H hybrid control. Results of Demer variety
take the same results of ESTAR F1 H hybrid. The effect of virus infection on pepper plants
were reduced when inoculation were done during flowering stage and post-flowering stage,
differences were significant between inoculated plants in both varieties.
A field survey of Pepper mild mottle (PMMV) and Cucumber mosaic (CMV)
Viruses was conducted in some plantation areas in Tartous and Lattakia Provinces. A total
of 1278 samples (782 from Tartous and 505 from Lattakia) were collected. Results of
Tis
sue Blot Immunobinding Assay showed the presence of PMMV in 0.39% and CMV in
11.42% in the collected samples. The percentage of CMV varied in Tartous and Lattakia
Provinces. In this study, PMMV was not recorded in Lattakia, whereas it was recorded in
Tartous in a small percentage (0.64%).
Using Tissue Blot Immunobinding Assay, the collected seeds from the infected
pepper fruits from Tartous fields showed the transmission of PPMV throughseeds in a ratio
of 0.70% to 0.87% according to seed resources, whereas CMV was transmitted in a high
percentage of 2.81% to 7.98% according to seed resources. PPMV was not recorded in leaf
samples or in seeds taken from Blozah District in TartousProvince.
The research aims to determine the water requirements by using drip irrigation,
microjet irrigation, sprinker irrigation and surface irrigation for pepper. The study showed
the following:
• The pepper don’t need to irrigate through mars and april
and the first third of may
because the effective rainfall is more than the trees water requirement.
• The irrigation efficiencies were 0.921, 0.886, 0.868 and 0.70 for drip, microjet,
sprinker and surface irrigation, respectively.
• the dayly irrigation averages for one plant by field studying were 1.084, 1.132,
1.152, 1.426 liter/day for drip and microjet and sprinkler and surface irrigation,
respectively.
• By regarding the surface irrigation as witness we can economize of water in one
year for one hectare 3595 m3, 3222 m3 and 2858 m3 by using drip, microjet and sprinker
irrigation, respectively.
• The product quantities were 3995, 3389, 3315, 2910 by using drip, microjet,
sprinker, and surface irrigation, respectively.
