Lavandula mairei Humbert is an endemic species of Morocco, it is considered as rare and threatened species. It grows spontaneously in arid and semi-arid bioclimates, and found its uses in traditional medicine for the treatment of various diseases such as gastrointestinal diseases, microbial infection, cough and asthma. With the optic of conservation, this study aims to evaluate the combined effect of temperature and pretreatment on L. mairei seeds germination. On the other hand, this study looks to assess the effect of different concentrations of gibberellin (GA3), polyethylene glycol (PEG 6000) and sodium chloride (NaCl) on seeds germination. The results revealed, an optimal germination temperature of 25 °C, and over 90 % of seeds are able to germinate without using any pretreatment. Nevertheless, pretreatment of the seeds with sulfuric acid and hydrogen peroxide increased the germination rate to over 96 %. It has also been demonstrated that treatment with gibberellin improves the germination rate of L. mairei seeds. In addition, the water deficit caused a drop in the germination rate (of about 11 %) starting from - 0.53 MPa. Thus, the salt stress estimated by the application of different concentrations of sodium chloride (NaCl) has shown that the germination percentage of L. mairei seeds decreased considerably when the concentration exceeds 150 mM. This study could be a basic guide for the possible cultivation and conservation programs of L. mairei Humbert, Moroccan endemic and threatened plant.

Lavandula mairei Humbert是摩洛哥的特有物种，被认为是稀有和受威胁的物种。它在干旱和半干旱的生物气候中自发生长，并在传统医学中用于治疗各种疾病，例如胃肠道疾病，微生物感染，咳嗽和哮喘。借助保护的光学方法，本研究旨在评估温度和预处理对玛氏乳杆菌的综合影响。种子发芽。另一方面，本研究旨在评估不同浓度的赤霉素（GA3），聚乙二醇（PEG 6000）和氯化钠（NaCl）对种子发芽的影响。结果表明，最佳发芽温度为25°C，超过90％的种子无需任何预处理即可发芽。然而，用硫酸和过氧化氢预处理种子可使发芽率提高到96％以上。还证明了用赤霉素处理可以提高玛氏乳杆菌的发芽率。种子。此外，缺水导致发芽率从-0.53 MPa开始下降（约11％）。因此，通过使用不同浓度的氯化钠（NaCl）估算的盐胁迫显示，当浓度超过150 mM时，玛氏乳杆菌种子的发芽率大大降低。这项研究可以为摩洛哥特有和濒危植物L. mairei Humbert的可能栽培和保护计划提供基本指导。
