Zinc (Zn) deficiency caused by inadequate dietary intake is a global nutritional problem, particularly in developing countries. Therefore, zinc biofortification of wheat and other cereal crops is being urgently addressed and highly prioritized as a research topic. A field study was planned to evaluate the influence of zinc application on grain yield, grain zinc content, and grain phytic acid concentrations of wheat cultivars, and the relationships between these parameters. Three wheat cultivars, C = Faisalabad-2008, C = Punjab-2011, and C = Millet-2011 were tested with five different methods of zinc application: T = control, T = seed priming, T = soil application, T = foliar application, and T = soil + foliar application. It was found that grain yield and grain zinc were positively correlated, whereas, grain phytic acid and grain zinc were significantly negatively correlated. Results also revealed that T, T, and T considerably increased grain yield; however, T only slightly enhanced grain yield. Grain zinc concentration increased from 33.1 and 33.7 mg kg in T to 62.3 and 63.1 mg kg in T in 2013-2014 and 2014-2015, respectively. In particular, T markedly decreased grain phytic acid content; however, maximum concentration was recorded in T. Moreover, all the tested cultivars exhibited considerable variation in grain yield, grain zinc, and grain phytic acid content. In conclusion, T was found to be most suitable for both optimum grain yield and grain biofortification of wheat.
饮食摄入不足导致的锌（Zn）缺乏是一个全球性的营养问题，在发展中国家尤为突出。因此，小麦和其他谷类作物的锌生物强化作为一个研究课题正亟待解决且被高度优先考虑。一项田间研究计划旨在评估锌施用对小麦品种的籽粒产量、籽粒锌含量和籽粒植酸浓度的影响，以及这些参数之间的关系。选用了三个小麦品种，即C = 费萨拉巴德 - 2008、C = 旁遮普 - 2011和C = 小米 - 2011，采用五种不同的锌施用方法进行测试：T = 对照、T = 种子引发、T = 土壤施用、T = 叶面喷施和T = 土壤 + 叶面喷施。结果发现，籽粒产量与籽粒锌呈正相关，而籽粒植酸与籽粒锌呈显著负相关。结果还表明，T、T和T显著提高了籽粒产量；然而，T仅略微提高了籽粒产量。2013 - 2014年和2014 - 2015年，籽粒锌浓度分别从T中的33.1和33.7毫克/千克增加到T中的62.3和63.1毫克/千克。特别是，T显著降低了籽粒植酸含量；然而，T中的浓度最高。此外，所有测试品种在籽粒产量、籽粒锌和籽粒植酸含量方面均表现出相当大的差异。总之，发现T最适合实现小麦的最佳籽粒产量和籽粒生物强化。
