On Some Mutants for Physiological Leaf Spots
Nine of the physiological leaf spot mutants were described and investigated linkage relation with marker genes. All of them were governed by single recessive genes respectively and the causal genes were designated as a series of spl (spotted leaves) as spl,, spl,......sf&. With eight of them except for sPZ~, the linkage groups were determined as follows: sj+-a linkage group corresponding to A t...
متن کاملFungi associated with leaf spots of nutsedge plants in north of Iran
Twenty fungal isolates associated with leaf spots of nutsedge plants (Cyperus spp.) from north of Iran (Guilan, Mazandaran, Zanjan and Golestan Provinces) are examined. According to the results of the morphological studies of grown fungi on culture media, Curvularia clavata, Curvularia lunata var. aeria, Dactylaria higginsii, and Myrothecium brachysporum are new taxa for Iran mycoflora and repo...
متن کاملdigestive amylase and glucosidases in the larval stage of elm leaf beetle, xanthogaleruca luteola (col.: chrysomelidae)
elm leaf beetle, xanthogaleruca luteola, is a serious pest (particularly at its larval stage) of elm trees in many areas. the existence of three important enzyms namely: ?-amylase, ?- glucosidase and ?-glucosidase in the midgut of the insect at its larval stage was investigated. optimum activity for ?-, ?-glucosidase and ?-amylase was recorded at phs 5.0, 6.0 and 6.0 against p-nitrophenyl-?-d-g...
متن کاملThe effects of host plants on the feeding indices and chemical activities of elm leaf beetle, Xanthogaleruca luteola (Muller) (Coleoptera: Chrysomelidae)
ABSTRACT- Elm leaf beetle (ELB), Xanthoga leruca luteola (Muller), is considered as one of the most important and destructive phytophagous pests of Ulmus species in the north of Iran. In the current study, the effects of three host plants including Ulmus carpinifolia, U. carpinifolia var. umbraculifera, and Zelkova carpinifolia, on feeding indices and biochemical processes of ELB were examined ...
