Application of Electrical Wave Transmission in Basic Research of Grafting

Lu Shan-fa and Yang Shi-jie   

Abstract: Electrical wave (EW) transmission from scion to stock across the grafting interface was related to the histological changes during the development of graft union. Variation wave (VW) could not be transmitted to stock from scion before isolation layer broken and callus interdigitation. As plasmodesmata formed secondarily at the interface between stock and scion where the isolation layer had disappeared, VW could be transmitted from scion to stock, but its velocity was not rapid until the vascular bridges form between two partners of graft union. Hence, the authors could deduce the degree of graft union formation by measuring whether VW could be transmitted from scion to stock or not and its velocity. EW trans mission method was a new tool for quickly detecting the formation of graft union.
