The reproductive system is essential for the structuring and transmission of genetic diversity. Understanding the reproductive biology of threatened endemic species is considered to be a crucial element for the implementation of effective conservation strategies. Given the lack of information and the insufficient state of knowledge on the reproductive system of L., a threatened medicinal species endemic to Morocco, we are the first to study the reproductive biology of two varieties of L.: var. (L.) Link and var. (Ball.) Maire. The reproductive biology of the two varieties was examined in detail by studying the development of the inflorescence, phenology of flowering, breeding system, pollinators, production, and seed dispersal. The experimental results described in this work suggest that L. is a gynomonic species, with a mixed autogamy-allogamy reproductive regime with a high predominance of allogamy. It appears to be partially self-incompatible, with allogamy rates for var. (Ball.) Maire and var. (L.) Link of 78.70% and 79.01%, respectively. It depends on pollination vectors to produce a large number of seeds. This study on the breeding system of L. provides a tool for developing management strategies and adequate conservation measures.
生殖系统对于遗传多样性的构建和传递至关重要。了解濒危特有物种的生殖生物学被认为是实施有效保护策略的关键要素。鉴于摩洛哥特有的濒危药用植物L.的生殖系统缺乏信息且研究不足，我们首次对L.的两个变种的生殖生物学进行了研究：L. var. (L.) Link和L. var. (Ball.) Maire。通过研究花序发育、开花物候、繁育系统、传粉者、种子产量和种子传播，详细考察了这两个变种的生殖生物学。这项工作中描述的实验结果表明，L.是一种雌花先熟的物种，具有自花授粉和异花授粉混合的生殖方式，其中异花授粉占主导。它似乎部分自交不亲和，L. var. (Ball.) Maire和L. var. (L.) Link的异花授粉率分别为78.70%和79.01%。它依赖传粉媒介来产生大量种子。对L.繁育系统的这项研究为制定管理策略和适当的保护措施提供了一个工具。
