Health and quality of zinc coated wheat seeds during storage

Abstract

ABSTRACT:The objective was to evaluate the effect of seed wheat coated with zinc, in its physiological, sanitary attributes and enzyme quality, during storage. We used two batches of seed, for seed treatment, we used commercial product as a source of zinc in the form of ZnSO 4 , along with fungicide and polymer. It was tested for levels 0, 1, 2, 3 and 4 mL ZnSO 4 kg -1 seed. The physiological quality, during the storage period, was analyzed by the tests: moisture content, hectoliter weight, germination, emergence, index emergence rate, tetrazolium and sanity test. It was concluded that the doses 3 mL and 4 mL of ZnSO 4 to assist in the ultimate expression of the seeds physiological quality, until six months stocked. This coating promotes a smaller reduction in the viability of seeds, furthermore, results in a lower incidence of fungi on seeds during storage. Also help to maximize the expression of physiological seed quality of higher and lower quality, respectively. The micronutrient zinc associated with fungicide and polymer had a lower incidence of fungi during the storage period.

Physiological performance of wheat seeds treated with micronutrients and protection products during storage

“…Similarly, Bittencourt et al (2000) reported a moisture content reduction in maize seeds, as a function of the low relative humidity values during 30 days of storage with difference of 0.5% between thiamethoxam seed treatment and untreated seeds at first 15 days of storage. However, Tunes et al (2016) observed that the moisture content of wheat seeds was not influenced by treatment with different doses of zinc sulfate (ZnSO 4 ) + fungicide (carboxin + thiram) + polymer applied using a syrup spray volume of 15 mL. kg -1 , and stored for six months under non-controlled environmental conditions.…”

Efectos inmediatos y tras almacenaje del recubrimiento con boro de semillas de algodón

“…Resultados similares han sido informados por Funguetto [30] para semillas de arroz recubiertas con zinc, un fungicida y un polímero, o por Lemes, et al [31], para semillas de trigo recubiertas con zinc, un fungicida y un polímero. Por otro lado, de Tunes, et al [32] [36] encontraron una reducción en el porcentaje de germinación para semillas de sorgo tratadas con zinc. Las diferencias entre los resultados descritos anteriormente podrían explicarse por las diferencias entre los cultivos en términos de eficiencia de uso de los nutrientes [31].…”
