Preliminary Different Rootstocks Eggplants Descendants Of Physiological And Biochemical Changes

Graft can induce character changes in the progenies of the scion plants. Seedling of cultivar eggplant was grafted onto the stem of wild eggplants. The growth of the scion was maintained until the scion produced self seeds. We sowed the seeds for two generations. Distinct character changes appeared in the progenies. Such as the content of anthocyanin is prevalent lower with the generations of the scion sowed normally without graft, the similar phenomenon also occurred in the content of protein, the active of PPO, SOD and CAT. The bud bursting seeds' SOD and EST isoenzyme spectrum of the progenies of the scion plants also has obvious difference with the original scion. Our experiment result shows that the character changes not to be caused simply by chromatin transformation but most likely the stress induced by graft.
