Abstract:

In this research, tuberlike galls which induced by thrip on ivy tree leaves were chosen as materials, and the physiological responses as well as partitioning of mineral nutrition, soluble protein and saccharide contents in galled and ungalled tissues were assayed. Results indicated that compared to the ungalled tissues, galling tissues decreased in many physiological indexes including hydrogen peroxide concentration, Peroxidase and phenylnine amonialase activities and the contents of malondialdehyde. Galling tissues decreased in photosynthetic rate but increased in respiratory rate. Galling tissues acted as a nutritive sink that accumulate more nutrition than surrounding ungalled tissues. Phytohormones and insects extracts alone can not induce the formation of galls, but cytokinins such as kinetin, 6BA and Zeatin can induce responses which are similar to the earlier response of thrip feeding.

Key words: Galling induction, Leafy gall, Plant cell physiological response
