Abstract

The effect of gametocides FW450 maleic hydrazide and Dalapone on the course of microsporogenesis gametogenesis and starch synthesis in pollen grains of winter rye ev ‘Esto’ was investigated Solutions containing various concentrations of tested substances were applied on leaves in amount of 25 ml and 50 ml per plant at the beginning at the full and at the end of shooting The effect of gametocides was detectable already in the phase of microspore formation when a decrease of anther weight pollen grain size and starch content in grains and an increase of the number of microspores with nonfinished development were observed The manner and the extent of injuries were dependent on the applied substance its concentration and on period of its applicationByl studován vliv gametocidů FW450 maleinhydrazidu a Dalaponu na průběh mikrosporogeneze gametogeneze a syntézu škrobu v pylových zrnech ozimého žita Esto Roztoky různých koncentrací byly aplikovány na list v množství 25 a 50 ml na rostlinu na začátku sloupkování v plném sloupkování a koncem sloupkování Gametocidní účinek se začal objevovat ve fázi mladých mikrospor Projevil se snížením váhy prašníků velikosti pylových zrn a obsahu škrobu v zrnech a zvýšením počtu mikrospor s neukončeným vývojem Míra a způsob poškození závisely na typu látky použité koncentraci a době aplikace
