Abstract

The research aims to study the situation of natural regeneration of the Cedrus libani A. in some afforested sites (Alnabe Matah, and Mawla Hassan) in Tartous, Syria; in order to determine the causes of weakness of the natural regeneration of Cedrus libani  in these sites, by checking the vigor of Cedrus libani  seeds through the germination under the influence of some environmental factors, and determine the status of the natural regeneration of Cedrus libani  in the studied sites. The germination tests showed a good vigor of Cedrus libani seeds which collected from afforested Cedrus libani forest stands. The seedlings stage is the main obstacle of the success of Cedrus libani natural regeneration; since most of the seedlings had died in the first year of their life because of the summer drought.

Key Words: Cedrus libani, natural regeneration, Alnabe Matah afforested site, Mawla Hassan afforested site, Tartous, Syria.

Abstract

Tomato stem pith necrosis disease has been observed in the greenhouses in Syria since the beginning of nineties in northern west of Aleppo, but recent surveys confirmed the existence of the disease in the coastal region (Tartous and Lattakia governorates), where tomato is cultivated intensively in greenhouses. The results of the survey showed that percentage of greenhouses infected with the disease in Tartous governorate during 2010 and  2011 were 17.7 % and 24.4% respectively, and the disease averages of spread were 0.19% and 0.28% respectively, where infected plants percentages were 0.72% and 0.97% respectively. The percentages of greenhouses infected with the disease in Lattakia governorate during the 2010 and 2011 were 23.20 and 24.86% respectively, and the disease averages of spread were 0.32 and 0.35% respectively, where infected plants percentages were 0.65% and 0.85% respectively. 60 isolates out of 100 isolates resulted from the survey, were characterized morphologically, physiologically and biochemically as Pseudomonas corrugate, where 12 isolates were identified as Pectobacterium carotovorum subsp. Carotovorum, and PCR was used to identify 4 isolates resulted from (pcc) with the aid of specific primers.

Key words: Tomato. Pectobacterium carotovorum subsp. carotovorum, Pith necrosis, Pseudomonas corrugate. Lattakkia, Tartous.
