[Effects of elevated atmospheric ethylene on the development of regenerative organs of short-stem wheat cultivars].
Laboratory experiments were performed to study cytoembryologic development of regenerative organs of wheat cult. 20-1-Shortstem and cult. Apogee in atmosphere with elevated concentration of ethylene. Development of wheat regenerative organs at a concentration of air ethylene of 1 mg/m3 resulted in peculiar changes in floret morphogenesis and partial or complete male barrenness. Cult. Apogee was found to be least vulnerable and, therefore, appears to be suitable for cultivation in greenhouses mounted in pressurized habitats including space station modules. Vulnerability of male reproductive organs in short-stem wheat to ethylene correlates convincingly with the sign of dwarfishness demonstrated by hybrid forms of one of praparents.
