Abstract—The conjugative development of male and female structures and reproductive processes of Halox-
ylon aphyllum—a desert xerohalophyte woody species from Chenopodiaceae, along the soil salinity gradient has
been investigated. Increase in soil salinity level and available soil moisture were considered the critical factors dur-
ing ontogenesis of female generative organs, determining seed production and seed quality of H. aphyllum.

Keywords: Haloxylon aphyllum, soil salinity, soil moisture deficit, reproductive biology, arid ecosystem, Kyzyl-
kum desert
