虽然铝（Al）对绝大多数被子植物是有毒的，但在一些植物中发现高浓度的铝（即< 1,000 mg·kg-1干质量）。在这里，我们研究了温带，落叶种Symplocos paniculata的Al积累行为，该属主要属于热带属，已知在其地上组织中积累高水平的Al。通过在有铝和无铝水培条件下的生长试验，我们发现金针叶具有积累铝的能力，营养液中缺乏铝会对树苗的生长性能产生负面影响。
Although aluminium (Al) is toxic for the vast majority of angiosperm plants, high concentrations of Al (i.e., < 1,000 mg·kg-1 dry mass) are found in some plants. Here, we investigate the Al accumulation behaviour in the temperate, deciduous species Symplocos paniculata, which belongs to a mainly tropical genus known to accumulate high levels of Al in its aboveground tissues. Based on a growing experiment in hydroponics with and without Al, we show that S. paniculata has the capacity to accumulate Al and that the absence of Al in the nutrient solution has a negative impact on the performance of saplings.
