Abstract

Soil and foliar application are the most widely used methods for adding micronutrients to maize. High quality micronutrient fertilizers, however, are difficult to obtain in developing countries; micronutrient seed coatings are an attractive and practical alternative. We applied this approach to maize (Zea mays L.) to demonstrate the effects of boron (B), iron (Fe), manganese (Mn), molybdenum (Mo) and zinc (Zn) sulfates on maize germination, vigor, seedling growth, seed yield and seed quality as well as on seed microelement concentration. Seed coating was tested on three representative Chinese soil types (sandy, purple and lime soils). Compared to untreated controls, coating maize seeds with micronutrients significantly increased the seed emergence rate, seedling height, leaf length, leaf width, leaf area, main root length, root number, above ground fresh biomass, above ground dry biomass, underground fresh biomass, underground dry biomass, ear thickness and yield in sandy, purple and lime soils. Coating maize seeds with micronutrients also significantly increased the yield and quality of maize seed compared to untreated controls including ear barren tip, ear length, ear thickness, grains/row, hundred seed weigh, and rows/ear. Also, B, Zn, Fe, Mn and Mo microelements accumulated in maize seed after coating the seed with micronutrients. Our findings indicate that micronutrient seed coating may improve nutrient uptake and production of maize hybrids.

微量元素包种对玉米的萌发、生长、产量和微量元素养分均有促进作用。
土壤和叶面施用是玉米添加微量元素最常用的方法。然而,在发展中国家很难获得高质量的微量营养素肥料;微量营养素种子包衣是一种有吸引力和实用的替代品。以玉米(Zea mays L.)为研究材料,研究了硼(B)、铁(Fe)、锰(Mn)、钼(Mo)和锌(Zn)硫酸盐对玉米萌发、活力、幼苗生长、种子产量和种子品质以及种子微量元素浓度的影响。在中国3种具有代表性的土壤类型(沙土、紫色土和石灰土)上进行了种子包衣试验。与未处理对照相比,包衣微量营养素显著提高了砂质、紫色和石灰土壤中玉米种子出苗率、苗高、叶长、叶宽、叶面积、主根长、根数、地上鲜生物量、地上干生物量、地下鲜生物量、地下干生物量、穗厚和产量。与未处理的对照相比,包膜微量营养素也显著提高了玉米种子的产量和质量,包括穗秃尖、穗长、穗厚、粒数/行、百粒重和行数/穗数。包膜处理后,B、Zn、Fe、Mn、Mo等微量元素在玉米种子中积累较多。研究结果表明,微量元素包衣剂可以提高玉米杂交种的养分吸收和产量。

期刊介绍: Biotechnic & Histochemistry (formerly Stain technology) is the official publication of the Biological Stain Commission. The journal has been in continuous publication since 1926. Biotechnic & Histochemistry is an interdisciplinary journal that embraces all aspects of techniques for visualizing biological processes and entities in cells, tissues and organisms; papers that describe experimental work that employs such investigative methods are appropriate for publication as well. Papers concerning topics as diverse as applications of histochemistry, immunohistochemistry, in situ hybridization, cytochemical probes, autoradiography, light and electron microscopy, tissue culture, in vivo and in vitro studies, image analysis, cytogenetics, automation or computerization of investigative procedures and other investigative approaches are appropriate for publication regardless of their length. Letters to the Editor and review articles concerning topics of special and current interest also are welcome.
