Abstract

A fast laboratory method for testing the germinalion of Orobanche crenata Forsk. and O. minor Smith was elaborated by using agar media containing root exudates from host and/or provocative plants. Ecophysiological conditions suitable for germination of both Orobanche species were found. The method proved useful also for studying the dynamics of the first ontogenetic stages of both Orohanche species: their germination, growth of procaulome and its attachment to the host plant were described. The terminology of the first stages of broomrapes' development is discussed.
