Abstract


Grafting black pepper (Piper nigrum) on resistant rootstocks of Piper colubrinum is a widely accepted technique to manage the problematic Phytophthora disease. To evaluate the influence of varieties and season on graft recovery, a preliminary study was conducted in 2000, in which the runner shoots of eight P. nigrum varieties were grafted on P. colubrinum rootstocks. Results show that regardless of the varieties, February and March are the best periods for graft production.
