Piper colubrinum Link., a grafting root-stock for Piper nigrum L., resistant to diseases caused by Phytophthora palmivora Butl. And Fusarium solani f. piperi

Abstract

The root system of black pepper (Piper nigrum) is susceptible to contamination by soil fungus Fusarium solani f. piperi and Phytophthora palmivora (Butl.). In laboratory tests the species Piper colubrinum Link., compatible with black pepper, showed a high resistance to diseases caused by the pathogenic soil fungi. It could be used as an endurable root-stock in extensive cultures for commercial purposes, provided the harvest is satisfactory. The grafting operation was successful in 98% of the cases. Vegetative growth of the grafted black pepper vines in experimental plots has been good. The report discusses the processing and care of the root-stocks, the grafting method use, and the final planting in the field. The grafted black pepper develops well only where the soil moisture available is constant.
