هدف البحث إلى دراسة تأثير حجم الأوعية في نمو شتول الفليفلـة "صـنفSnapper " اسـتخدمت أوعية بلاستيكية بحجمين مختلفين، كانت أبعاد الأوعية الأولى 8×8 سم و الثانية 12×12 سم. أظهـرت النتائج أن استعمال الأوعية ذات الأبعاد الكبيرة قد زاد من معايير نمو الشتول مقارنة بالأوعيـة الأصـغر حجماً. إذ تفوقت الشتول المنتجة في الأوعية الكبيرة بنحو 14 % في متوسط طول الشتول و بنحـو 16 % في متوسط عدد الأوراق مقارنة بالشتول المنتجة في الأوعية الأصغر حجماً. كما تفوقت شـتول الأوعيـة الكبيرة بالوزن الرطب، سواء للنبات الكامل أو أحد أجزائه المنفصلة، فقد بلغ الوزن الرطب للنبات الكامـل في الأوعية الكبيرة 98.26 غ مقارنة مع 27.2 غ في الأوعية الأصغر حجماً.
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 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 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.
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.
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 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.
