摘要

通过种子引发向植物提供微量营养素可以提高幼苗活力并提高作物产量。在塞尔维亚潘切沃进行了为期两年的田间试验，目的是研究锌（Zn）种子引发对三个玉米杂交种在缺乏植物有效锌的钙质黑钙土上的田间表现的影响。种子引发处理为：对照（不引发）、水引发和用4mM硫酸锌水溶液引发。种子引发对植株早期生长、株高、产量构成、籽粒产量和籽粒锌浓度有显著影响。锌引发促进了植株生长，提高了植株的最终高度。在两个降水量对比的生长季节和三个测试的玉米杂交种中，锌引发导致粮食产量比对照平均增加约18%，比水引发平均增加约8.4%。植物生长参数、粮食产量构成因素与粮食产量之间存在显著关系。在降水较少的季节，两个杂交种和一个杂交种在第二个季节通过锌引发提高了籽粒锌浓度。。结果表明，使用含锌量较高的种子可以提高石灰性黑钙土上玉米的综合田间表现。Ac ce pt ed p ap er

Seed priming with zinc improves field performance of maize hybrids grown on calcareous chernozem

Delivery of micronutrients to plants through seed priming improves seedling vigour and increase crops yields. Two-year filed trial was conducted in Pančevo, Serbia, with aim to study the effect of seed priming with zinc (Zn) on field performance of three maize hybrids on calcareous chernozem deficient in plant available Zn. Seed priming treatments were: control (without priming), water priming and priming with 4 mM zinc sulphate water solution . Seed priming had significant effect on early plant growth, plant height, yield components, grain yield and grain Zn concentration. Znpriming promoted plant growth and increased final plant height. Across two growing seasons with contrasting precipitation and three tested maize hybrids, Zn-priming resulted in an average increase of grain yield by about 18% compared to control, and by about 8.4 % compared to water priming. A significant relationship between plant growth parameters, grain yield components and grain yield was detected. Grain Zn concentration was increased by Zn-priming in two hybrids in the season with less precipitation and in one hybrid in the second season.. The results imply that using the seeds with elevated Zn content can improve overall field performance of maize grown on calcareous chernozem. Ac ce pt ed p ap er

期刊介绍： The Italian Journal of Agronomy (IJA) is the official journal of the Italian Society for Agronomy. It publishes quarterly original articles and reviews reporting experimental and theoretical contributions to agronomy and crop science, with main emphasis on original articles from Italy and countries having similar agricultural conditions. The journal deals with all aspects of Agricultural and Environmental Sciences, the interactions between cropping systems and sustainable development. Multidisciplinary articles that bridge agronomy with ecology, environmental and social sciences are also welcome.
