The action of a high temperature (40 degree C, 3 h) on the content of free sugars and photosythetic pigments was investigated. The heating stimulated a protochlorophyllide accumulation and did not affect free sugar content in etiolated seedlings. During greening (1 h) of heated plants a decrease of the level of photosythetic pigments and essential growth of the amount of disaccharides was shown. A similar character of a change of free sugar content in a leaf and coleoptile was found during greening of etiolated plants, heating and at combination of heat and light factors
