ECOLOGICAL-GEOGRAPHICAL CRITERIA OF FORECASTING REACTIONS OF TROPIC AND SUBTROPIC PLANTS FOR HOTHOUSE CONDITIONS

By Alexander Sergeevich Demidov

Abstract

The work covers 29 species of the tropic and subtropic plants from 11 families and 19 genuses of the different biomorphological groups. The aim is to develop the methods and procedures of forecasting reactions of the tropic and subtropic plants for the moderate zone hothouse conditiuons (as an example of the Fund Hothouse of Main Botanic Garden of Russian Academy of Sciences). The preliminary plant analysis methods enabling to forecast the conditions necessary for provision of the small development cycle have been proposed. A possibility to restorate the ontogenesis by means of the action on the development of the plants by the temperature conditions has been shown firstly. The reasons for transfer of the certain species into the reproductive state have been revealed, and the dependence of beginning the flowering upon the degree of the thermal factor stress in the pre-flowering period has been determined.
