Some species of the Syrian Flora were waned, other were extincted.
therefore, it was so nessesary to make a releve for restrict and classify the
survival species in order to put them under conserving & improvement genetic
program. The aim of this
research was to study the plant diversity in West
Homs; one of important basaltic region in Syria, and to concentrate on the wild
legumes and the Rhizobium strains which cohabit with. A plant survey was
carried out showed the existence of 365 species belong to 202 genera and 51
families, 15 species are endemic.12 species not observed previously in Syria but
are found in Lebanon were recorded,in addition another 3 species not listed at
all neither in Syria nor in Lebanon were mentioned. The geobotanical
attributes and the economical importance of the gathered species were
determined.as so as systematic keys of the most important families were
suggested...The root nodules of 10 species belong to 10 genera of wild legumes
were studied. Rhizobium strains were isolated and cultured in vitro. The
morphologic characters were studied microscopy. The pure strains were
reserved by refrigerator.
