Abstract

Decent taste and the salt and drought tolerance of purslane (Portulaca oleracea L.) make it a potential vegetable crop for the future. This study investigates the effects of foliar application of 5-aminolevulinic acid (5-ALA), a new plant growth regulator, on the growth, mineral composition, and bioactive compounds of purslane. Three different levels of 5-ALA (0, 25 and 50 mg L-1) were sprayed at 1) two leaved stage and 2) upon the onset of inflorescence appearance on purslane seedlings. Results showed that 5-ALA application enhanced biomass accumulation in the plant shoot and increased shoot length. Concentration of nitrogen, potassium, magnesium, zinc and iron increased in the shoots of 5-ALA treated plants, while the calcium concentration remained unaffected. Phenolic compounds of the plant were catechin, chlorogenic acid, and ellagic acid, with catechin being the main compound. Further on, Trans-ferulic acid, hesperedin and eugenol were detected in the extract of 5-ALA-treated plants. Application of 5-ALA also increased fatty acids in the plant leaves. Total phenolics, ascorbic acid contents and antioxidative activity of shoot were increased in the 5-ALA-treated plants. Moreover, pH of root exudates of the plants was decreased in 5-ALA treated plants. The results revealed that exogenous 5-ALA has growth regulatory effects and can enhance the growth, and improve nutritional quality and pharmaceutical properties of P. oleracea. In this regard, the best results were obtained by application of 50 mg 5-ALA L-1.

叶面施用5-氨基乙酰丙酸提高马齿苋的生物活性潜力和营养价值，是一种有发展前景的蔬菜

马齿苋(马齿苋L.)良好的口感和耐盐耐旱性使其成为未来潜在的蔬菜作物。本文研究了叶面施用新型植物生长调节剂5-氨基乙酰丙酸(5-ALA)对马齿苋生长、矿物成分和生物活性成分的影响。在马齿苋幼苗2叶期和花序开始时分别喷洒0、25和50 mg L-1 3种不同浓度的5-ALA。结果表明，施用5-ALA促进了植株地上部生物量积累，增加了地上部长度。5-ALA处理植株茎部氮、钾、镁、锌和铁的浓度增加，而钙的浓度未受影响。该植物的酚类化合物有儿茶素、绿原酸和鞣花酸，以儿茶素为主要化合物。进一步，在5- ala处理的植物提取物中检测到反式阿魏酸、橙皮苷和丁香酚。5-ALA的施用也增加了植物叶片中的脂肪酸。5- ala处理的植株茎部总酚类物质、抗坏血酸含量和抗氧化活性均有所提高。此外，5-ALA处理的植株根系分泌物pH值降低。结果表明，外源5-ALA具有生长调节作用，能促进马齿苋的生长，改善其营养品质和药用性能。在此方面，施用50 mg 5-ALA L-1效果最好。

期刊介绍： The Journal of Applied Botany and Food Quality is the Open Access journal of the German Society for Quality Research on Plant Foods and the Section Applied Botany of the German Botanical Society. It provides a platform for scientists to disseminate recent results of applied plant research in plant physiology and plant ecology, plant biotechnology, plant breeding and cultivation, phytomedicine, plant nutrition, plant stress and resistance, plant microbiology, plant analysis (including -omics techniques), and plant food chemistry. The articles have a clear focus on botanical and plant quality aspects and contain new and innovative information based on state-of-the-art methodologies.
