寄生植物与寄主之间的相互作用是农业和生态学中的一个重要课题。然而，关于半寄生虫马先蒿的情况却知之甚少。了解马先蒿对寄主的依赖和偏好，是成功培育马先蒿属植物和了解其在自然群落中所起作用的基础。研究了两种草本寄主（Trifolium repens和Polypogon monspeliensis）对头马先蒿（Pedicularis cephalantha）存活和生长性能的影响。每盆种植5株头花苗和2株寄主植物，对照组不种植寄主植物（处理1）。以三种组合方式种植寄主植物：只种植黑穗槐（处理2）或monspeliensis（处理3）或两者混合种植（处理4）。结果表明，在寄主植物存在的情况下，头棘鱼的生长表现更好，寄主植物对头棘鱼的正常发育比生存更重要。禾草寄主monspelensis被证明比豆科寄主T. repens更好地寄主cephalantha。本研究证实了头棘对寄主植物的高度依赖性和寄主偏好。这是中国马先蒿在整个生命阶段（从种子到种子）的栽培表现的首次报道。
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).
