A study on the seed morphology of the genus cassia L. sensu lato in the Sudan

Abdalla, W.E., Medicinal and Aromatic Plants Research Institute et al. [2010]

Morphological characters of seeds from 23 Cassia L. sensu lata species from Sudan were examined with the aid of Stereo Microscope in order to clarify their taxonomic status. The seeds of all members of the genus Senna (with the exception of S. bicapsularis) were areolate, whereas the seeds of Cassia sensu stricto and Chamaecrista species were not areolate and the shapes of the latter two gener ...

Biological control of chickpea wilt caused by fusarium oxysporum f. sp. ciceris

Yousif, F.A., University of Nile Valley et al. [2010]

This study was conducted in an attempt to control chickpea (Ocer arietinum L.) wilt, caused by Fusarium oxysporum f. sp. ciceris, using antagonistic properties of soil microorganisms. It also aimed at avoiding problems resulting from the use of chemical fungicides. A Trichoderma sp. was isolated from the rhizosphere of a resistant chickpea variety (ICCV -2) and a Bacillus sp. from the rhizosph ...

This study was conducted to investigate and identify the reason for the death of wild fruit fly larvae in the laboratory. The toxic activity of the presumptive bacterial isolate from fruit fly larvae was examined on the invasive fruit fly Bactrocera invadens larvae. The isolate was identified as Bacillus thuringiensis (B.t.) on the bases of morphological characteristics and biochemical tests. ...
