Title: Anatomical Mechanisms of Resistance to Field Dodder (Cuscuta campestris Yuncker) in Some Horticultural and Field Crops
Author: Farah, A.F.; El-Hassan, G.M.
Abstract: Plants of thirty-four crop species were anatomically screened for resistance to field dodder (Cuscuta campestris Yuncker). On the basis of a suggested resistance evaluating scale, that ranges from 0 to 3, the tested crops were classified into four main groups, namely, group 0 (resistant), group 1 (tolerant), group 2 (susceptible) and group 3 (highly susceptible). The screening test revealed that among the 34 tested crop species, only three were resistant, ten were tolerant, seventeen were susceptible and four were highly susceptible. The resistance of the tested crops involved different mechanisms which could be grouped under two types, i.e., non-stimulated (passive) and stimulated defense mechanisms.
