Teliospores of Tilletia harclayana germinated equally well on the surface of 2 % water agar, soil extract agar and in cavities made in water agar. Maximum germination occurred at 29 °C under 12 h photoperiod with artificial daylight (cool fluorescent light). There was marked increase in germination when the teliospores in bunted grains were pre‐treated for 30 min at 60 °C. Seventeen‐week‐old tehospores did not germinate while 73 week‐old‐tehospores showed retention of good germinability. Teliospores buried at 2 mm depth showed no germination whereas those at the moist surface germinated to produce sporidia. Implications of these results in the disease development are discussed.
The treatment of barley seed with five fungicides (Brassicol, Ceresan Wet, Thiram, Ziram and Aureofungin) induced both morphological and cytological abnormalities. Germination was reduced up to 10 days over controls and a reduction in seedling height occurred. Chromosomal abnormalities consisted of fragments, aneuploidy, bridges, lagging and unequal distribution of chromosomes, tripolar spindles and spindle inhibition. Of the fungicides tested, Ziram was most effective in producing morphological and cytological abnormalities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
