We revise the taxonomy of the myrmicine ants of the Monomorium monomorium species-group for the Arabian Peninsula. Six species are recognized: Monomorium aeyade Collingwood & Agosti, 1996, M. clavicorne André, 1881, M. exiguum Forel, 1894, M. holothir Bolton, 1987, M. mohammedi sp. n., and M. sarawatense Sharaf & Aldawood, 2013. On the basis of the worker caste, we describe Monomorium mohammedi...

The ethanolic extract and its chloroform soluble and chloroform insoluble fractions of the roots of Baliospermum montanum were investigated in albino rats to evaluate the analgesic activity. Tailo - flick animal model was employed to test analgesic activity and compaired with a standard drug, Diclofenac sodium. The results indicate that the ethanolic extract and its chloroform soluble fraction ...

salinity stress is one of the most important abiotic stress factors limiting the plants' growth. seed priming is known as a method which improves the germination performance in seeds in stress conditions. the objective of this study was to compare the effectiveness of hydropriming and halopriming on germination performance of secale montanum while growing under the nacl-salinity stress. hydropr...

ITHIN the genus Secale L. hybrids between various perennial forms have all shown regular meiotic chromosome behavior as have hybrids between different annual strains belonging to S. cereale L. In all hybrids between S. cereale and perennial forms, however, a translocation figure has been observed a t metaphase I in the PMC’s. The maximum association is apparently a ring-of-six, but this is seld...

Physiological effect of six levels of water stress (0, -0.1, -.03, -0.6, -0.9 and -1.2 MP) was studied on seed germination and plumule as well as radicule growth length in three species namely: Agropyron elongatum, Agropyron desertourm and Secale montanum. Polyethylene glycol (PEG) was used to provide appropriate water potentials. A total of 100 seeds in four replications (Petri dishes) were so...
