Bio-environmental features of flowering of hybrid tea roses on the Southern Coast of the Crimea

The terms of flowering of hybrid tea roses on the Southern Coast of the Crimea are studied. Early-, mid- and late-flowering cultivars were identified and biological minima of temperatures necessary for the beginning of their flowering were determined. The permanent flowering capacity of tea-hybrid roses under the conditions of the Southern Coast of the Crimea is studied and the dependence of the timing of each of the four blooming periods from the amounts of active and effective air temperatures, accumulated to their beginning, is specified.

Keywords: CULTIVAR, TERMS OF FLOWERING, BIOLOGICAL MINIMA OF TEMPERATURES, AMOUNT OF TEMPERATURE, PERMANENT FLOWERING CAPACITY
