study on biological control and systemic induction of peroxidase enzyme activity in tomato plant infected with root-knot nematode (meloidogyne javanica) by pseudomonas fluorescens cha0 antagonist
biological control of root-knot nematode meloidogyne javanica by application of pseudomonas fluorescens cha0 was evaluated under greenhouse condition. results showed that p. fluorescens (109 cfuml-1) as shoot spray significantly reduced in no. of eggmass and egg per individual eggmass as comparison to control. application p. fluorescens as shoot spray induced systemic activation of peroxidase (...
متن کاملbiological control of root-knot nematode (meloidogyne javanica) by pseudomonas fluorescens cha0 and trichoderma harzianum bi in tomato
root-knot nematodes (meloidogyne spp.) are among the most important groups of plant-parasitic nematodes, causing damage and yield losses to most cultivated plants. the bacterium pseudomonas fluorescens cha0 and the fungus trichoderma harzianum bi were investigated for biological control capability and systemic induction of resistance against the nematode m. javanica under glasshouse conditions....
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

15 صفحه اولInfluence of Urea, Hydroxyurea, and Thiourea on Meloidogyne javanica and Infected Excised Tomato Roots in Culture.
Urea (U), hydroxyurea (HU), and thiourea (TU), in various concentrations, were added to chemically defined plant tissue culture medium on which Meloidogyne javanica was reared on excised tomato roots. Concentrations as low as 3 ppm HU or 12 ppm TU inhibited nematode maturation by 70-90% 4 weeks after inoculation, and the coenocytes in the parasitized tissue were poorly developed. Gall weight wa...
