Maximum colony growth inhibition was observed due to Pseudomonas PS2 (74%) as compared to PS1 (71%) on trypticase soy agar (TSM) plates after 5 days of incubation. Light and scanning electron microscopic examination showed hyphal coiling, vacuolation, coagulation and granulation of cytoplasm resulting in lysis of hyphae of M. phaseolina by pseudomonads. Cell free culture filtrates of strains PS...

Background and objectives: Variation of active substances in medicinal plants during growth has been studied and the optimum harvest time has been determined for many medicinal plants. Ducrosi anethifolia is one the species belonging to Apiaceae family that has been used to improve the odor of food and drink. It is used also to treat catarrh, headache and backache in f...

SUMMARY In this research, which was done for two years, we investigated various liquid and solid media without feeder ceells, for the ability to support growth of P. carinii. Data obtained from counting the organisms nuclei showed that, addition of Cyclo­heximide, penicillin, & streptomycin to neopeptone­N-Acetyle Glucoseamine (N.P.G. medium) can provides growth requirements of organism in its...

Effects of Nigella sativa Allelochemical Substances on Growth-Inhibiting Flixweed Compared With Wheat (Triticum aestivum)

Use of performance-enhancing substances is widespread among men and women athletes and body builders, professional or amateur, adolescent or adult. Many of these substances are illegal or have adverse effects. This article describes the action and effects of androgenic and growth hormones, their legality, their potential for abuse, and their impact on mortality.

Advances made recently in the study of plant growth substances and their function in normal growth have raised the question of their possible role in atypical and pathological growth and specifically in the gall development induced by Phytomonas tumefaciens (Smith and Town.) Bergey et al. A suggestion of their presence was first given by the marked epinasty of leaf petioles in plants inoculated...
