РЕПРОДУКТИВНА БІОЛОГІЯ РОСЛИН РОДИНИ АLOACEAE В УМОВАХ ОРАНЖЕРЕЙНОЇ КУЛЬТУРИ

Abstract

The article presents the results of the study of the reproductive biology of succulent plants of the Aloaceae family in the introduction. Representatives of the family are part of the collection of succulent plants of the O.V. Fomin Botanical Garden,which contains over 190 species, subspecies and hybrids of plants of three genera: Aloe Linne – 86, Haworthia Duval – 74, Gasteria Duval – 23 taxa. In addition, x Gasteraloe Guillaumin (Gasteria x Aloe), x Gasterhaworthia Guillaumin (Gasteria x Haworthia), x Astroworthia G.D Rowley (AstrolobaUitewaal x Haworthia). Most plant species are included in the international red lists. In the process of forming this part of the collection, the morphology of flowers, inflorescences and seeds was investigated, phenological observations of flowering and fruiting were conducted, methods of vegetative and seed reproduction of family members were developed. Phenological observations have shown that the main flowering period is the spring summer period, but Aloe under greenhouse conditions is characterized by two more peaks (August, December). We have found that, in addition to simple or complex tics, in the vast majority of species, Aloe haworthioides is characterized by inflorescences of ears; perianth shaped tubular or cylindrical, inherent in the vast majority of species and performs, in our opinion, a protective function. The flowering of a single flower takes place in three stages, providing a self-pollination effect that is characteristic of crop conditions only for certain Aloe species, and the viability of the pollen is closely related to the ambient temperature. Freshly harvested seeds obtained by self-pollination or cross-pollination have a sufficiently large germination, but if stored in any way after three months, the germination increases. We have proposed a method of increasing the viability of seeds of plants of the Aloaceae family 2.5-3 times and developed a method of vegetative propagation of representatives of the genera Haworthia and Gasteria leaf cuttings.
