Abstract
Abstract
The occurrence of leaf galls and the relation between the host plant and the causative insect are discussed. The leaves, galls, and leaves freed from galls of Salix fragilis have been examined by one-way and two-way paper chromatography and a separation of the major constituents achieved on powdered cellulose columns. The galls and leaves freed from galls were compared by band chromatography and the results suggest that one phytochemical change initiated by the sawfly is an accumulation of catechins, leucoanthocyanins and a ninhydrin positive substance.
