The Greek endemic Bornmuellera emarginata, known for its Ni hyperaccumulation capacity, is a promising candidate species for use in agromining. At the same time, the installation of photovoltaic systems on agricultural land has recently been increasing. Field observations that populations of this species usually occupy shaded places under shrubs or trees led us to study the effect of different shading levels on the growth of B. emarginata, with a view to combine the cultivation of the species with photovoltaic panels in the same area. The experiment was conducted under greenhouse conditions and lasted 210 days after sowing (DAS). Seeds were sown directly into 2‐L pots filled with ultramafic soil collected from the field. Three plant samplings (81, 140, and 210 DAS) were conducted during the experiment to determine a set of morphological and physiological parameters of the species (fresh and dry plant biomass, plant height, number of lateral shoots, total number of leaves, proline and chlorophyll concentrations) alongside with its nickel yield at different levels of shading (0%, 20%, 35%, 60%, and 90%). Growth of B. emarginata was only significantly affected at the highest shading level. Nickel yield of the species increased over time and was maximized at the end of the experiment. The highest nickel yield per plant was observed at the intermediate shading level (35%). Bornmuellera emarginata can be considered as a candidate nickel hyperaccumulator for cultivation in ultramafic or nickel‐polluted areas under photovoltaic panels with corresponding shading, providing important environmental benefits.

不同遮荫水平对用于农矿开采的镍超富集植物 Bornmuellera emarginata 生长的影响

希腊特有的边缘博恩穆勒拉以其镍超积累能力而闻名，是用于农业采矿的有前途的候选物种。与此同时，近来农业用地光伏系统的安装量不断增加。实地观察发现，该物种的种群通常占据灌木或树木下的阴凉处，这使我们能够研究不同遮荫水平对其生长的影响。边缘 B.，以期将该物种的种植与同一区域的光伏板结合起来。该实验在温室条件下进行，播种后持续210天（DAS）。将种子直接播种到装满从田间收集的超镁铁质土壤的 2 升盆中。实验过程中进行了 3 个植物采样（81、140 和 210 DAS），以确定该物种的一组形态和生理参数（鲜和干植物生物量、株高、侧枝数、叶总数、脯氨酸）和叶绿素浓度）以及不同遮蔽水平（0%、20%、35%、60% 和 90%）下的镍产量。的成长乙。边缘仅在最高阴影级别下才受到显着影响。该物种的镍产量随着时间的推移而增加，并在实验结束时达到最大。在中等遮蔽水平（35%）下观察到每株植物的最高镍产量。边缘博恩穆勒拉可以被视为候选镍超富集植物，用于在具有相应遮荫的光伏板下的超镁铁质或镍污染区域种植，提供重要的环境效益。
