本研究的主要目标是建议将藏红花作为摩洛哥一些降雨量低且不稳定的农业区的高附加值可持续替代作物，以促进其社会经济发展。在推荐商业生产之前，必须对藏红花香料的质量进行评估。为此，我们首次在海拔、土壤和气候差异较大的11个不同试验区的试验田种植藏红花。采用高效液相色谱法定量分析了藏红花中最重要的组成成分藏红花素、微藏红花素和藏红花醛，它们分别对藏红花的颜色、味道和气味负责。以干物质百分比计算，所有站点的平均值为29.01 +/- 5.6；14.04 +/- 7.1和0.22 +/- 0.11。统计分析表明，经过3年的研究，藏红花在每个特定环境下都是稳定的（p < 0.05）。与此同时。同一时期内樟脑含量变化较大（p < 0.05）。这表明在不同环境下生产的藏红花的采后加工可能需要改进。环境对藏红花品质的影响分析表明，海拔高度仅对藏红花品质有影响（R-2 = 0.84, p < 0.05）。(C) 2009 Elsevier B.V.版权所有
The primary goal of this study was to propose saffron as a sustainable substitute crop with high added value in some Moroccan agricultural areas with low and erratic rainfalls, for their socio-economical development. The quality of the saffron spice has to be evaluated prior to recommendation for commercial production. For this purpose, saffron was grown in experimental plots for the first time in eleven different experimental zones with a disparity of altitudes, soils and climates. High-performance liquid chromatography (HPLC) was used to quantify the most important saffron components crocins, picrocrocin, and safranal which are respectively responsible for its colour, taste and odour. The respective average values, in % dry matter, across all sites altogether are 29.01 +/- 5.6; 14.04 +/- 7.1 and 0.22 +/- 0.11. The statistical analysis shows that crocins are stable under each specific environment tested (p > 5%) for 3 years of study. Meanwhile. there was a large variability in safranal content for the same period (p < 0.05). This suggests that post-harvest processing of saffron produced under different environments may need to be improved. Analysis of environmental impact on saffron quality showed that just the altitude affects crocins (R-2 = 0.84, p < 0.05). (C) 2009 Elsevier B.V. All rights reserved.
