摘要
羽扇豆(羽扇豆属)是对农业系统的可持续性具有重要意义的豆科植物,因为它们可以通过固定大气中的氮来改善土壤质量,而且对不同气候和土壤条件具有良好的适应性。此外,它们还具有很高的营养价值,特别是由于种子的蛋白质含量很高。然而,植物的生产力和新陈代谢会受到基因型、气候条件和播种方法的影响。在这项研究中,我们评估了气候条件和播种日期对 L. albus cv. Estoril、L. angustifolius cv. Tango 和 L. luteus cv. Cardiga 种子产量、营养成分和生物碱的影响。结果表明,种子和蛋白质产量、营养特征和生物碱含量与品种之间存在很大差异,而且地点也有显著影响。Lupinus albus cv. Estoril在产量和低生物碱含量之间表现出很好的折衷,在本试验条件下是一种可用于食品和饲料的有趣基因型。
Agronomic, Nutritional Traits, and Alkaloids of Lupinus albus, Lupinus angustifolius and Lupinus luteus Genotypes: Effect of Sowing Dates and Locations
Lupins (Lupinus spp.) are legumes with high relevance for the sustainability of agricultural systems as they improve the soil quality, namely, through the fixation of atmospheric nitrogen, and have good adaptability to different climates and soil conditions. Besides, they possess high nutritive value, especially due to the high protein content of the seeds. Nevertheless, the plants’ productivity and metabolism can be influenced by the genotype, the edaphoclimatic conditions, and the sowing practices. In this work, the effect of edaphoclimatic conditions and sowing dates on the productivity, nutritional factors, and alkaloids of the seeds of L. albus cv. Estoril, L. angustifolius cv. Tango, and L. luteus cv. Cardiga was evaluated. High variability in the seeds and protein productions, nutritional traits, and alkaloid content related to the species was observed, along with a significant effect of the location. Lupinus albus cv. Estoril showed a good compromise between productivity and low alkaloid content, being an interesting genotype for food and feed use in the conditions of this trial.
