Vigor da cultivar BMX Potência RR de soja durante o beneficiamento e períodos de armazenamento

Abstract

o vigor das sementes de soja durante as etapas do beneficiamento e ao longo do armazenamento. O experimento foi desenvolvido no Instituto Federal Goiano, Câmpus Rio Verde, e na empresa Sementes Goiás. Utilizou-se o delineamento inteiramente casualizado, segundo o esquema fatorial triplo 6 x 2 x 4 (seis etapas do beneficiamento, duas condições de armazenamento e quatro tempos de armazenamento) com três repetições. Foram utilizadas sementes de soja Glycine max (L.) Merrill, cultivar BMX Potência RR. As sementes foram avaliadas ao longo do armazenamento (0, 3, 6 e 9 meses) quanto ao teor de água, teste de tetrazólio e emergência em areia. Os dados foram analisados por meio de análise de variância e regressão adotando-se o nível de 0,05 de significância. Concluiu-se que o beneficiamento das sementes de soja não afetou a qualidade fisiológica das sementes e a cultivar BMX Potência RR apresentou qualidade fisiológica superior pelo teste tetrazólio (acima de 80%) apesar do vigor, germinação e emergência se apresentarem altos durante nove meses de armazenamento e o comprimento de raiz e de plantas jovens normais foi influenciado negativamente pelo tempo. Em câmara climatizada as sementes apresentam maior viabilidade dependendo do teor de água do produto.Vigor of cultivar BMX Potência RR of soybean during processing and storage periods A B S T R A C TThe aim of the present study was to evaluate the effect of soybean seeds during processing and storage. The experiment was conducted at Federal Institute of Goiás, Campus Rio Verde and the company Seeds Goiás. A completely randomized design was used according to the triple factorial scheme 6 x 2 x 4 (six stages of processing, two storage conditions and four storage times), with three replications. Seeds of soybean (Glycine max L.) Merrill cultivar BMX Potência RR were used. The seeds were evaluated during storage (0, 3, 6 and 9 months) as to moisture content, tetrazolium and emergence in sand. Data were analysed by analysis of variance and regression, adopting the 0.05 level of significance. It was concluded that: the processing of soybean seeds did not affect the physiological quality of soybean seeds and cultivar BMX Potência RR showed higher physiological quality by tetrazolium test (above 80%); although the vigor, germination and emergence remained high for nine months storage, the root length and number of normal young seedlings were negatively influenced by the weather. In climate chamber seeds showed higher viability depending on the moisture content of the product.

Performance of Treated Seeds of Different Soybean Cultivars in Function of Environments and Storage Periods

“…Similar results were obtained by Vieira et al (2013), which verified that the physiological quality in untreated soybean seeds was maintained when stored at 10 ºC for 12 months, but there was a reduction when stored at 25 ºC. In contrast, Juvino et al (2014) also studied the storage of soybean seeds in an air-conditioned chamber and verified that seeds showed better conservation compared to the natural environment. Demito and Afonso (2009) observed degradation and loss of physiological quality when soybean seeds are stored at room temperature in conventional warehouses.…”

Processing on the physical and physiological quality of chickpea (Cicer arietinum L.) seeds

“…Also, Gadotti et al (2020) observed that coriander processing was efficient in separating seeds with better sanitary quality, by removing contaminated seeds. Similar results have been found for other crops, such as castor bean (Santos-Neto et al, 2012) and soybean (Teles et al, 2013;Juvino et al, 2014;Moreano et al, 2018;Folquini et al, 2022). Regarding chickpea, there is no information in the literature so far.…”

Evolution of the physical and physiological quality of soybean seeds during processing

“…Different results were found by Juvino et al (2014) at a SSP for soybean who found that processing didn't change the seed vigor results. Silva et al (2011) at a SPP for soybean seed processing verified the increase of mechanical damages during processing due to bucket elevators.…”
