Dynamics of floral organogenesis of Syringa josikaea Jacq. at the time of introduction in conditions of the arctic Murmansk climate

Research data of the morpho-physiological analysis of the generative buds of Syringa josikaea Jacq., introduced in Murmansk, are presented. It is shown that in conditions of the Arctic climate the differentiation of axes of the inflorescence and organogenesis of flowers can occur both a year before flowering and in the spring period two or three months before its inception. The polyvariety of the floral organogenesis of the Hungarian lilac, growing in different districts of Murmansk has been revealed. Experimental data on the asynchronous processes of the lilac floral differentiation were first obtained in the Arctic.
