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.
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.
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 aimed to study the effect of size of container on the growth of
seedlings pepper "Snapper". Two different sizes of plastic containers, with
dimensions 8×8 cm and12×12 cm were used, Results showed that the use of
containers with large
dimensions had increased the growth of seedlings
compared with the use of smaller ones. A significant increase, of about 14%
was observed in the average length of seedlings and about 16% in the average
number of leaves produced in the large containers as compared with seedlings
produced in smaller ones. Also the fresh wet weight, whether for the plant or its
separate parts was significantly higher in seedlings produced in the large
containers. The plant fresh wet weight in the large container was 26.98 g vs.,
2.27 g in the smaller ones.
This study was conducted to evaluate the effect of pepper (pipiemento
variety), and eggplant (Dara variety) seed's treatment on germination
characteristics, and the impact of eggplant seeds treatment on seedling quality.
The seeds were treated for
24 hours in glass containers, in which the ratio of
seeds to the applied media was 1:5, the concentration of the mineral solution
was 0.1%, while the concentration of each of GA3 and the organic nutrient
solution was 0.01%.
The media were continuously aerated by passing a current of pure oxygen
(O2), at sufficient pressure to homogenously mix the seeds in the media. The
seeds were dried up after 24 hours of treatment to remove the excess moisture.
Seeds were germinated in Petri dishes, and soil-full containers to assess the
germinability, and seed vigor. The eggplant seeds were also sown in peat-moss
containing pots (8 cm indiameter) to study the influence of treatment on
seedling quality.
The results showed that treatment efficiency depends on the nature of the
used media, and crop. In addition, it has been revealed that the aeration of
media enhanced the germination, accelerated the seedling growth, and
improved their quality.
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.
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 study has been carried out using the onion and pepper seeds to
determine the effects of the aqueous medium temperature, during treatment
with oxygen, on the germination percentage seed vigor and for determining the
period needed for the treat
ment with the oxygen as well.
The treatment period has taken ١٢-٣٦ hours according to the kind of crop
and the medium temperature, which varied between ١٠-٣٠ °C.
Results of the study indicated that the treatment of seeds with oxygen, in an
aqueous medium, improved the germination percentage and the seed vigor. The
period needed for the treatment of the seeds with oxygen differs according to
the kind of crop and the temperature of the medium and varies between ١٨-٢٤
hours with respect to the onion seeds, and between ٢٤-٣٦ hours regarding the
pepper seeds. The period needed for treatment with oxygen decreases with the
rise of temperature.
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.
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.
