Identification of genetic resources of field resistance to barley leaf rust in local germplasm of cultivated barley
The barley leaf rust has been important in recent years in Iran. In order to identify the genetic resources of resistance to this disease, 207 Iranian barley landraces were studied. The germplasms were investigated at the field of Iraqi-Mahalleh research station in Gorgan as the disease hotspot under natural incidence over three years. The results showed that four genotypes including KC18638 an...
متن کاملAlterations of NADPH:protochlorophyllide oxidoreductase quantity and lipid composition in etiolated barley seedlings infected by Barley stripe mosaic virus (BSMV).
SUMMARY To understand the phenomenon by which infection of seed-transmitted Barley stripe mosaic virus (BSMV) alters membrane structures and inhibits protochlorophyllide biosynthesis of dark-grown barley (Hordeum vulgare L.) plants, we analysed the presence of NADPH:protochlorophyllide oxidoreductase (POR, EC 1.3.1.33) and the galactolipid content and fatty acid composition. The amount of POR i...
متن کاملInfluence of simulated rain on dispersal of rust spores from infected wheat seedlings
Spores of both Puccinia recondita f. sp. tritici and P. striiformis (brown rust and yellow rust of wheat) are thought to be primarily dispersed by wind. The results of experiments, using a rain simulator with uniform drop sizes (2.5, 3.4, 4.2 or 4.9 mm), on the effect of rain on dispersal of brown (leaf) rust and yellow (stripe) rust spores are reported. Experiments on both pathogens were done ...
متن کاملCatalase-chlorophyll Relationship in Barley Seedlings.
For over two decades H. VON EULER (3) and his coworkers have studied the relationship of catalase to chlorophyll. In their work they utilized various chlorophyll defective plants including genetic albinos, variegated, chlorotic and etiolated plants. In general, they found a parallelism between chlorophyll content and catalase activity. NAKAMURA (11) working with a number of higher and lower for...

increases over controls were found when root segments were incubated in phosphorus solutions containing 10-3 A D)NP ancd at lowx temlperatture. The increased Pi in Al-roots did niot result in an increase in the total amounit of l)hosphorus incorporated into phosphorylated compounds. Aluminum treatnment miiarkedly decreased the incorporation of P32 into sigar phosl)hates but increased the pool s...
