马先蒿引种栽培问题的探讨

马先蒿属植物作为一系列重要生物学问题的经典研究材料和颇具开发潜力的野生花卉资源,颇受生物学家和园艺学家的关注。然而其栽培问题至今未能解决, 致使其开发利用受到限制。多数生物学家将马先蒿栽培困难的原因归咎于其半寄生特性, 长期以来专注于探寻合适的寄主植物。作者在查阅文献时发现, 具半寄生特性的马先蒿在有伴生植物的栽培条件下成苗率仍然很低。由此推断可能存在其它更为重要的限制因子。本文在结合文献信息和本课题组考察结果的基础上, 指出了菌根真菌和其它生态因子在马先蒿引种栽培中的重要地位, 提出了打破传统理论的束缚而结合具体情况全面考察的观点。

on Cultivation of Pedicularis L.

As classic materials for the study of a number of significant biological issues and as promising potential ornamental plants, species of Pedicularis L. have become a great concern to biologists and horticulturists. However, cultivation of the genus has long been unsuccessful, which hinders their exploitation to a large extent. The majority of botanists tend to ascribe the difficulties encountered in cultivation to their hemiparasitism and cultivation experiments have been partially focused on the search of proper host plants. Previous reports indicated that the establishment of Pedicularis seedlings was very poor even in the presence of their host plants. It is speculated that there may be other important factors inhibiting the cultivation of the genus. Based on literatures and our investigations, the important roles of mycorrhizal fungi and other ecological factors in the cultivation process of Pedicularis species are pointed out in the present paper. And multifactor analysis of specific species is suggested by getting rid of traditional single host-plant factor investigation.
