Budding Compatibility of Almond and Plum on Some Wild Species and Interspecific Hybrids of Almond

Cytogenetical Analysis of Iranian Wild Almond Species

In this study, the karyo-systematic studies on the Iranian wild almond species A .communis L., A. corduchoruom Bornm., A. trichamygdalus woronow, Amygdalus lycioides Var. horrida Spach were done by the karyological methods. The meristem cells of the root tip were used for these studies. In each species, ten suitable metaphase plates were chosen and photographed so that the morphology of the chr...

preliminary identification and typing of pathogenic and toxigenic fusarium species using restriction digestion of its1-5.8s rdna-its2 region

background: fusarium species are capable of causing a wide range of crop plants infections as well as uncommon hu­man infections. many species of the genus produce mycotoxins, which are responsible for acute or chronic diseases in ani­mals and humans. identification of fusaria to the species level is necessary for biological, epidemiological, pathologi­cal, and toxicological purposes. in this s...
