هدف البحث إلى دراسة تأثير معاملة بذور الباذنجان الصنف البلدي الزهري ببعض مستخلصات الأعشاب البحرية في تحسين خصائصها الإنباتية, فضلا عن دراسة تأثيرها في نمو الشتول الناتجة عنها و قدرتها على تحمل صدمة التشتيل.
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 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 research aims to study the effect of certain organic and amino
compounds in the growth and production of tomato under green
houses conditions.Hulay F1 hybrid tomato and two organic
commercial vehicles differing in composition Hupost and
Boldo
uzerwere used.The experiment done in a way randomized
complete blocks designed , with three replicates per treatment , and
10 plants per replicate . Seedlings WERE Prepared in beet moss
using trays of Alstrepor inside the greenhouses.
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.
Bioeffect of some Syrian Myrtus communis L. leaves extracts in growth of some pathogenic microorganisms, which were isolated from Al-Assad hospital laboratory in Lattakia, was tested by disc diffusion method. Results showed that cold and hot water ex
tracts have antibacterial activity against all Gram positive and negative bacteria, and pathogenic Candida albicans except Klebsiella pneumoniae. All organic extracts have antibacterial activity against Proteus vulgaris, Entrococcus faecium, Staphylococcus aureus and Staphylococcus albus.
Pseudomonas aeruginosa and Pseudomonas fluorescens were affected by most of the organic extracts, and the most bioactivity was by methanol extract, and all inhibition zones of extracts were bigger than inhibition zones by control
antibiotics. Serratia marcescens and Acinetobacter calcoaceticus were affected by methanol (with highest inhibition zone 37.33 and 27.33 mm respectively), ethanol, acetone and ethyl acetate extracts, but resistant to the others. Klebsiella pneumoniae affected by ethanol extract only with inhibition zone 20.33 mm.
Results of bioactivity according to a various solvents used in this study demonstrate that Syrian Myrtus communis L. leaves extracts have antimicrobial activity, so expected to be potential sources of natural antibacterial and antifungal products against some pathogenic bacteria and fungi in the future.
The trial was carried out during the season 2014, on grapevines
of Al-Baladi. Al Baladi, 20 years old, grafted onto rootstock, and trained in the trellis way, to study the influence of different levels of 4 times/season soil applied seaweed extract , on some qualitative and quantitative characteristics of Al-Baladi grapes.
