摘要

摘要本研究旨在评估不同浓度铝的影响：（25、50和100 mg l−1的氯化铝AlCl3。6H2O）对椰枣茎增殖、植物化学物质以及体外培养的抗氧化酶活性的增强作用。在培养基中添加浓度为50 mg l−1的铝对芽再生的影响最大，与其他浓度（包括对照处理）相比，这种物质还增加了每罐芽的数量（分别为73.34%和8.2芽/罐）。对椰枣嫩芽的生化分析表明，高浓度的氯化铝（100 mg l−1）导致总脯氨酸含量的显著积累，抗坏血酸过氧化物酶的高活性，以及氮、磷、钙、镁和叶绿素的显著减少，与50 mg l−1浓度相比，叶片中上述元素含量最高，叶绿素含量最高。

Effect of aluminum on the growth of the in vitro culture tissues of the date palm (Phoenix dactylifera L.) cv. Um-Aldehin

Abstract This study was carried out to evaluate the effect of different concentrations of aluminum: (25, 50 and 100 mg l−1 of aluminum chloride AlCl3. 6H2O) on the enhancement of shoot multiplication, phytochemicals, as well as, antioxidant enzyme activity of in vitro cultures of the date palm cv. Um-Aldehin. The addition of aluminum in a concentration of 50 mg l−1 to the medium exhibited most effects on shoots regeneration and this substance also increased the number of shoots per a jar (73.34% and 8.2 shoots/jar, respectively), compared to the other concentrations, including the control treatment. A biochemical analysis of date palm shoots revealed that the high concentration of aluminum chloride (100 mg l−1) led to a significant accumulation of the total proline content, and to a high activity of ascorbate peroxidase, as well as a significant reduction in nitrogen, phosphorus, calcium, magnesium and chlorophyll, compared to the concentration of 50 mg l−1 for which there were recorded the highest contents of the mentioned elements, together with the highest content of chlorophyll in leaves.
