Two field experiments were conducted over three growing seasons (2006-07, 2008-09 and 2009-10) to evaluate Se-enriched pasta through foliar fertilization at various rates and timing of application on 4 durum wheat varieties. Our findings confirm the effectiveness of foliar Se fertilization to increase Se concentrations in durum wheat grain, even at high Se rates (120gSeha(-1)). Se fortification was significant across different genotypes, with greater Se accumulation in landraces ('Timilia') and obsolete varieties ('Cappelli'), with respect to modern varieties. The Se content in the grain was increased by up to 35-fold that of the untreated control. The Se concentration decreased during milling (11%), while processing and cooking of pasta did not show significant decreases. This biofortification stategy had no effects on grain quality parameters, except for reduced gluten index in the high-gluten variety PR22D89, as well as for the sensorial properties of the spaghetti.
在三个生长季节（2006 - 2007年、2008 - 2009年和2009 - 2010年）进行了两项田间试验，以评估通过对4个硬粒小麦品种进行不同施用量和施用时间的叶面施肥来生产富硒意大利面的效果。我们的研究结果证实了叶面施硒对提高硬粒小麦籽粒中硒浓度的有效性，即使在高硒施用量（120 g Se ha⁻¹）下也是如此。在不同基因型中，硒强化效果显著，与现代品种相比，地方品种（“Timilia”）和过时品种（“Cappelli”）积累的硒更多。籽粒中的硒含量增加到未处理对照的35倍。在制粉过程中硒浓度下降了11%，而意大利面的加工和烹饪过程中硒浓度没有显著下降。这种生物强化策略对籽粒品质参数没有影响，除了高筋品种PR22D89的面筋指数降低以及意大利面条的感官特性有所变化外。
