درس تأثير معاملة بذور الفليفلة "الصنف Pipiemento " و بـذور الباذنجـان "الـصنف Dane " فـي الخصائص الإنباتية، كما درس أيضاً تأثير معاملة بذور الباذنجان في نوعية الشتول. عوملت البذور مدة 24 ساعة في أوانٍ زجاجية بلغت فيها نسبة البذور إلى الوسط المـستخدم فـي المعاملة (ماء كان أم محلولاً مغذياً) 1 : 5 ، و بلغ تركيز المحلول المعدني 1.0 % و كل من محلول حامض الجبريليك و المحلول المغذي العضوي 01.0 % جرت تهوية الأوساط بإمرار تيار مستمر من الأوكـسجين النقي بضغط يكفي لخلط البذور بشكلٍ متجانس داخل الوسط، جففت البذور بعد انتهاء فترة المعاملات فـي درجة حرارة الغرفة لإزالة رطوبتها السطحية. نُبتت بذور الفليفلة و الباذنجان في أطباق بتري علـى ورق ترشيح لاختبار الإنبات، و في أحواض مملوءة بالتراب لاختبار قوة البذور. كما زرعت بذور الباذنجان في أصص بلاستيكية (قطرها 8سم) مملوءة بالبيت_موس المخصب لدراسة تأثير المعاملة في نوعية الشتول. أظهرت الدراسة أن فعالية المعاملة تتوقف على الوسط المستخدم و نوع المحصول. كما بينت أيضاً أن معاملة البذور في أوساط مؤكسجة، من المحلول المغذي العضوي قد ساعدت في تنشيط الإنبات، و تسريع النمو و تحسين نوعية الشتول.
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 experiment was carried out to assess the germinability and seedling
growth rate of some treated vegetable seeds (i.e. onion, carrot, and tomato) with
aerated - aqueous solutions.
Seeds were treated for 24 hours with 0.1% of both succinic acid
and
nutrient solution, and the seeds to medium ratio was 1:5.
The soaking solution was continuously aerated by an air pump. At the end
of treatment, the seeds were dried up at room temperature to eliminate the
excess superficial moisture.
The research aims to study the effect of the treatment of the
eggplant seeds- pink local kind in some seaweed extracts to improve
the germination characteristics, as well as the study of their impact
on the growth of the resulting seedlings and their ability to
withstand the transplanting shock.
The research was conducted on 25male lambs of Awassi
sheep to compare the effect of using different levels of whole cotton
seeds (WCS). The experiment extended for 70 days.
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.
The effect of different treatments on carob seed germination was studied.
The results showed that, seed scarification was the most effective method in
increasing germination rate as well as the use of concentrated sulfuric acid for 30 minutes
reac
hing 100%, followed by the treatment with alcohol for 60 minutes, and immersing
seeds in hot water for 60 minutes.
The results also indicated that the speed of germination when seeds were scarified
was the best (I.D.=14.5), followed by the treatment with concentrated sulfuric acid for 30
minutes (I.D.=21.5), alcohol for 60 minutes (I.D.= 38) and immersing seeds in hot water
for 60 minutes (ID.=60).
