the present study is based on the investigation of a soil hyphomyces, paecilomyces lilacinus, an opportunistic bio-control agent, in controlling root-knot nematode meloidogyne javanica on tomato in greenhouse conditions. p. lilacinus, effectively promoted the growth of plants inoculated with m. javanica by suppressing its pathogenesis as root galling by the nematode and egg mass production was ...

Y OUNG et al. (1994) recently found that a putative transposable element (Lytl) is present at high abundance in the genomes of individuals sampled from a group of red-fruited species of Lycopersicon, and at a much lower abundance in green-fruited species of this genus. Similar or somewhat lower abundances were found in Solanum species believed to be closely related to Lycopersicon, and even low...

Calotropis proceran (Asclepidaceae) is an evergreen plant and widely distributed in Hormozgan province. This plant has the allelopathic properties including germination inhibition, plumule and radicle growth reduction. In this study the effect of different concentrations (0, 5, 10, 20, 40 and 60%) of dry leaf water extraction of this plant on the germination of cucumber (Cucumis sativus), tomat...
