The development of optimal conditions of long-term deposition of improved clones of a Phlox paniculata L. collection

The research objective was to optimize conditions for long deposition of Phlox paniculata L. The experiments were made in the Laboratory of Clonal Micropropagation of Garden Plants, by Laboratories of fruit growing of Russian State Agrarian University - Moscow Agricultural Academy named after K.A. Timiryazev in 2016-2018. Two varieties of Phlox paniculata L.: the variety Johann Sebastian Bach of the selection of Yu.A. Reprev (1987) and the variety Uspekh of the selection of P.G. Gaganov (1937) were chosen as the object of the study. As a result of the research, a non-stop technology of storage of Phlox paniculata L. was pro- posed, in which the viability of plants remained at the level of 90-95 % for 12 months of storage. Accounting and observation, statistical data processing were carried out using two-factor analysis of variance. The conditions for long-term storage of the collection plants of Phlox paniculata L. in a bank of healthy clones, and presented the results of an experiment on the effect of the concentration of cinnamic acid and mannitol on the preservation of in vitro plants of Phlox paniculata were examined...
