In this work, the influence of two regulated deficit irrigation (RDI) treatments and three different rootstocks on the quality of pistachios was evaluated by analyzing different parameters: morphological analysis, physicochemical analysis and sensory analysis.
The results obtained in terms of the choice of rootstock revealed that Pistacia atlantica had increased production yields, nut weight, mineral content, higher intensities of characteristic sensory attributes and a higher degree of consumer satisfaction, than the other rootstocks studied. Moreover, the results established that the application of RDI on pistachio cultivation had no significant influence on production yield, weight, size, colour, water activity or mineral composition. Furthermore, T1 treatment (stem water potential < -1.3 MPa) resulted in higher intensities of characteristic sensory attributes and a greater level of satisfaction among international consumers.
These results confirm that the application of deficit irrigation (T1) contributes to an increase in overall product quality. Furthermore, Pistacia atlantica rootstock provided better yield and quality than the other rootstocks studied.
在本研究中，通过分析不同参数（形态分析、理化分析和感官分析），评估了两种调亏灌溉（RDI）处理和三种不同砧木对开心果品质的影响。
关于砧木选择的研究结果表明，与其他研究的砧木相比，大西洋黄连木的产量、坚果重量、矿物质含量增加，特征感官属性强度更高，消费者满意度更高。此外，结果表明，RDI应用于开心果种植对产量、重量、大小、颜色、水分活度或矿物质组成没有显著影响。此外，T1处理（茎水势 < -1.3 MPa）导致特征感官属性强度更高，国际消费者的满意度更高。
这些结果证实，亏缺灌溉（T1）的应用有助于提高整体产品质量。此外，大西洋黄连木砧木比其他研究的砧木提供了更好的产量和品质。
