assessment of urediniospore germination of puccinia striiformis at various temperatures on agar and detached leaves of wheat
the percentage of urediniospore germination of two isolates of yellow rust {puccinia striiformis f. sp. tritici) namely, wyr 69/10 |race 104e 137(1)] and isolate wyr 79/4 |race 41e 139 (4)], was studied at various temperatues between 5-20°c on agar and the adaxial surface of detached leaves on a layer of benzimidazole agar. four replicates for five temperature treatments were arranged as a ...
متن کاملEffects of temperature on urediniospore germination, germ tube growth, and initiation of infection in soybean by phakopsora isolates.
ABSTRACT Temperature is a critical factor in plant disease development. As part of a research program to determine how specific environmental variables affect soybean rust, we determined temperature effects on urediniospore germination and germ tube growth of four isolates of Phakopsora pachyrhizi, one each from Brazil, Hawaii, Taiwan, and Zimbabwe, and an isolate of P. meibomiae from Puerto Ri...
متن کاملNovel fungitoxicity assays for inhibition of germination-associated adhesion of Botrytis cinerea and Puccinia recondita spores.
Botrytis cinerea and Puccinia recondita spores adhere strongly to polystyrene microtiter plates coincident with germination. We developed assays for inhibition of spore adhesion in 96-well microtiter plates by using sulforhodamine B staining to quantify the adherent spores. In both organisms, fungicides that inhibited germination strongly inhibited spore adhesion, with 50% effective concentrati...
متن کاملEffect of cations on germination & germ tube development of Puccinia coronata uredospores.
Previous work in this laboratory (20) showed that germ tubes of Puccinia coronata uredospores would form structures in vitro resembling those found in infected host plants (18). This so-called vesicle formation occurred on Difco gelatin in the pH range of 6.2 to 6.9 on addition of 14 to 22 X 10-5 M Zn. Under these conditions germ tube length was reduced, and in some cases the percentage germina...
متن کاملIdentification of the Germination Self-inhibitor from Uredospores of Puccinia striiformis
MACKO, V., E. J. TRIONE, and S. A. YOUNG. 1977. Identification of the germination self-inhibitor from uredospores of Puccinia striiformis. Phytopathology 67:1473-1474. The endogenous germination inhibitor from uredospores a germination assay employing fresh, water-washed, stripe of the stripe rust fungus, Puccinia striiformis, was identified rust uredospores. The chemical structure was confirme...
