摘要
在追求大豆高产的过程中,种子质量是一个限制因素。然而,真菌和虫害会对种子的性能产生负面影响,而工业种子处理 (IST) 是一种用于最大限度减少病原体和虫害侵袭的工具。经过处理的种子通常会储存到播种前,这可能会导致种子质量下降。这项工作旨在评估经过 IST 处理的大豆种子的物理和生理质量,以及随后在自然和受控环境中的储存情况。实验采用完全随机方案(时间 x 贮藏系统 x IST)中的四分法设计,四次重复。55I57RSF IPRO 大豆栽培品种接受了杀真菌剂(metalaxyl-M、噻虫嗪和氟虫腈)和杀虫剂(噻虫嗪和氰虫啉)的 IST 试验,是否与聚合物和干粉结合使用,随后在受控的自然环境中贮藏。评估了含水量、千粒重、发芽率、首次发芽数、发芽速度指数、加速老化、苗长、干物质转移和出苗砂试验。综合气候技术并不影响种子的含水量和千粒重。然而,在受控环境中贮藏可使含水量降低更多,千粒种子重量降低更少。IST 对发芽率、首次发芽数、发芽速度指数和加速老化试验均有负面影响。除只施用杀虫剂的处理外,IST 对植株长度有负面影响。只施用杀虫剂或杀真菌剂以及杀虫剂、杀真菌剂和聚合物混合施用的种子的干传质受到负面影响,但影响程度较小。种子在沙地中的萌发受到所有处理的负面影响。无论采用哪种处理,在整个贮藏过程中,所评估的所有反应都有所降低,而在自然环境中贮藏的种子受到的影响更大。
Quality assessment of soybean seeds submitted to industrial seed treatment and stored in a natural and controlled environment
Seed quality is a limiting factor in the search for high soybean yields. However, fungi and insect pests can negatively interfere with their performance, and industrial seed treatment (IST) is a tool used to minimize the attack of pathogens and pests. The treated seeds are often stored until sowing, which can lead to a reduction in their quality. This work aimed to evaluate the physical and physiological quality of soybean seeds submitted to IST, with subsequent storage in a natural and controlled environment. The experiment was conducted in a split-split-plot design in a completely randomized scheme (time x storage systems x IST) with four replications. Soybean cultivar 55I57RSF IPRO was subjected to IST with fungicide (metalaxyl-M, thiabendazole, and fludioxonil) and insecticide (thiamethoxam and cyantraniliprole), combined or not with polymer and dry powder, with subsequent storage in a controlled and natural environment. The moisture content, thousand-seed weights, germination, first germination count, germination speed index, accelerated aging, seedling length, dry matter transfer, and emergence sand test were evaluated. IST did not affect the moisture content and weight of a thousand seeds. However, storage in a controlled environment provided a greater reduction in moisture content and a smaller reduction in the weight of a thousand seeds. IST negatively affected germination, first germination count, germination speed index, and accelerated aging test. IST negatively affected plant length, except in the treatment where only insecticide was applied. The dry mass transfer was negatively affected but with less intensity in seeds subjected only to the application of insecticide or fungicide and the combination of insecticide, fungicide, and polymer. Seed emergence in the sand was negatively affected by all treatments. Regardless of the treatments, all responses evaluated showed a reduction throughout storage, with greater intensity in seeds stored in the natural environment.
期刊介绍:
The Journal of Stored Products Research provides an international medium for the publication of both reviews and original results from laboratory and field studies on the preservation and safety of stored products, notably food stocks, covering storage-related problems from the producer through the supply chain to the consumer. Stored products are characterised by having relatively low moisture content and include raw and semi-processed foods, animal feedstuffs, and a range of other durable items, including materials such as clothing or museum artefacts.
