摘要The interaction between parasitic plants and their hosts is an important topic in both agriculture and ecology. Little, however, is known about that of the hemiparasite Pedicularis. It is essential to understand the host dependence and preference of Pedicularis for successful cultivation of plants in this genus and for understanding the roles they play in natural communities. We tested the effects of two herbaceous host species (Trifolium repens and Polypogon monspeliensis) on the survival and growth performance of Pedicularis cephalantha. Five P. cephalantha seedlings and two host plants were planted in each pot. In the control, no host plants were planted (treatment 1). Host plants were planted in three combinations: only T. repens (treatment 2) or P. monspeliensis (treatment 3) or a mixture of both (treatment 4). The results showed that P. cephalantha performed better in the presence of host plants, and host plants are more essential to P. cephalantha for proper development than for survival. The grass host P. monspeliensis proved to be a better host plant for P. cephalantha than the legume host T. repens. The high dependence of P. cephalantha on host plants and its host preference were demonstrated in this study. This is the first report of the performance of Chinese Pedicularis species in cultivation throughout all life stages (from seeds to seeds).
