Abstract
The capacity of elicitors in crude hyphal wall preparations (CHWE) and in protein fractions of culture filtrate (PFCE) of Phytophthora capsici (Pc) pathogenic on pepper, and Phytophthora nicotianae var. parasitica (Pp) non -pathogenic on pepper, to cause cell browning, to increase alkalinization and conductivity of the medium and to stimulate phytoalexin production and PAL activity has been compared on cell cultures of two isogenic pepper lines, susceptible (QS) and resistant (QR) to P. capsici.
