Fruit growing
and viticulture of South Russia

Annotation

Knowledge of the seasonal development of introduced plants allows us to assess their adaptive potential in the new growing conditions, the prospects of their cultivation, and also is an important component in the development of cultivation technologies. In the period from 2012 to 2018, the features of seasonal rhythms of the development of alternative species of evergreen ground cover lawn-forming plants of the genus Liriope Lour. and Ophiopogon Ker Gawl. Under the conditions of humid subtropics of Russia were studied. The studied taxa are characterized by a long growing season (March-December) with growth peaks in the spring (April-May) and autumn (October-November) months. Under the humid subtropics of Russia, the objects of research go through all stages of development, which allows us to conclude that they are adapted to climatic conditions when they are not fully consistent with the ecological optimum of the studied taxa. High winter hardiness and drought tolerance of the studied representatives of the genera Liriope Lour and Ophiopogon Ker Gawl. in the region of research were noted. However, high air temperatures in the summer period against the background of insufficient moisture supply can lead to a short-term growth suspension. Significant differences in the timing and duration of flowering and fruiting compared to natural areas were found. In research region conditions, a shift of these phenophases to a later date with a decrease in they duration is noted. This fact indicates that the conditions of the humid subtropics of Russia are not fully consistent with the ecological optimum of the studied plants and causes a decrease in the productivity of generative reproduction. Against the background of oppressed seed reproduction, high vegetative reproduction efficiency was noted. This fact meets fully the need for planting material and decorative plantings formation. The research results confirm the prospects of plants of the genus Liriope Lour. and Ophiopogon Ker Gawl. under consideration for wide cultivation in the conditions of the zone of humid subtropics of Russia.
