the mycorrhizal fungi are the most important micro-organism among the soil micro flora which via genetical, physiological and ecological changes lead to more yield in symbiotic plants. the piriformospora indica sav. verma, aj. varma, rexer, g. kost & p. franken 1998, is one of well known endomycorrhizal fungus with different beneficial effects on diverse monocots (poaceae) and dicots (brassica...
the chemical compound dl-?-amino-n-butyric acid (baba) has been introduced as a promoter of induction of resistance in plants against plant pathogens. in this study, promotion of induction of some such defense compounds as peroxidase and polyphenol oxidase enzymes through dl-?-amino-n-butyric acid application against root knot nematode (meloidogyne javanica) was investigated in cucumber. result...

Endophytic fungi, Neotyphodium spp. symbiotically infect host grasses, Fescue arundinacea Schreb. and F. pratensis Huds. and Mealybug, Phenococcus solani Ferris attacks some forage plants. To evaluate the role of these fungi to control this pest, four genotypes of F. arundinacea and two genotypes of F. pratensis were used. Plant tillers were split into two sections, one section of which was fre...
