INFLUENCE OF THE METHOD AND DURATION OF STRATIFICATION ON THE OUTPUT OF AMPELOPSIS CORDATA LIANA SEEDLINGS

Currently, the objects of attention among architects and designers reviving the landscape approach in the design of urban environments are citywide and courtyard spaces, homesteads, etc. of reconstructed historical cities and new urban formations. Ampelopsis cordata liana is one of the most interesting among the representatives of Vitaceae family for a number of signs. The purpose of the study is to establish the influence of the method and stratification duration on Ampelopsis cordata’s seeds germination. Observations of seed germination were carried out according to the author's method developed by Khlevny D.Ye. Ampelopsis cordata liana seeds were divided into rounded, halves and quarters according to external signs. The average length of the shoot and internodes was measured biometrically. The number of nodes on the shoot was determined visually. The obtained data were processed by the method of variance analysis. As a result of the conducted studies, it has been found that the stratification of Ampelopsis cordata seeds for 40 days in a humid environment most effectively influences the appearance of the germinal root, due to the fact that stratification for 40 days in a humid environment most effectively influenced seeds germination. Further plants development (the appearance of the germinal root, hypocotyl, cotyledons and epicotyl), accordingly, passed in the best way in the same variant, in addition to stratification. The speed of seeds germination was influenced by their shape. Seeds in the form of a quarter germinated faster than those in the form of a half and rounded, more than 2 times, since in accordance with the research methodology, at least three years of research data are needed to obtain reliable conclusions, the observations are to be continued.
