Physiological and biochemical parameters of Ficus species and cultivars under dehydration conditions on the Southern coast of the Crimea

Abstract

The results of the studies of proline content, peroxidase, catalase, polyphenol oxidase activity and chlorophyll fluorescence induction (ChFI) parameters in leaves of Ficus species and cultivars under controlled dehydration conditions are presented. It was shown that the ChFI parameters, the most sensitive to the lack of water availability, are the characteristics of the chlorophyll fluorescence fast phase. Proline content, peroxidase and polyphenol oxidase activity can be used to addition diagnose of drought resistance of the plants of the genus Ficus. The cultivars Sabrutsiya Rozovaya, Sary Stambulskij and the species F. palmata are relatively drought tolerant.
