Název v původním jazyce

The interaction of abscisic acid and gibberellins during prehavest sprouting and dormancy of Barley kernels

Popis výsledku v původním jazyce

We studied the relationship between the germination of kernels in intact ears of barley (cvs. Akcent and Krona) and the hormonal activities (abscisic acid and gibberellins) in the stages of wax and full maturity of kernels. Barley ears were incubated for5 days in a darkened room (germinator) under 98% relative humidity, after 8-hour treatment with one of the following solutions: 10 uM of abscisic acid (ABA), 20 uM of fluridone, 10 uM of gibberellic acid (GA3) and 30 uM monensin. In the wax stage the kernels of control variants of both varieties did not sprout in the ears. After treatment with gibberellin and fluridone the kernels of the Akcent variety germinated (30%). Monensin applications considerably suppressed germination in ears of both varieties. In the stage of full maturity sprouting was observed in all variants of both varieties with the exception of those treated with monensin (less than 5%).
