Determination of the season-acclimation of photosynthetic apparatus by heat-induced changes in chlorophyll fluorescence

Abstract

Resistance to damage from freezing temperatures is one of the most adaptive properties of "evergreen" (shoot bark, felloderma, needles) woody and bush plant tissues. Species-specific processes accompanying transition of chloroplasts to a frost resistant state (reduction of photochemical activity, the change of chemical structure and structural organization of thylakoid membranes) determine criterion for estimation of its seasonal dynamics. Information on the degree of frost resistance of chloroplasts is necessary for successful introduction of plants, and also important in determining measures for protection from light frosts.
