“…Our data on Pearson correlation corroborate Pereira et al (2019), who also reported that grain treatment interfered in the relationship between emergence in the sand with the other tests physiological tests in maize. Indeed, based on the correlation values of Table 4, the most suitable test for predicting wheat seedling emergence in the sand varied with chemical treatment.…”

“…The evaluation of the physiological potential of the grains was carried out by means of the tests of germination (MAPA 2009), first germination count (MAPA 2009), accelerated aging (ISTA 2017), electrical conductivity (AOSA 2002), modified cold test (Pereira et al 2019), emergence in the sand test (Pereira et al 2019), dry seedling mass (Nakagawa 1999), as well as seedling growth tests (shoot length, root length, and total seedling length), according to the method described by Abati et al (2014).…”

“…Furthermore, sowing rarely occurs in areas free from pests or phytopathogens, requiring that the seeds be treated with the pesticides (Suzukawa et al 2019). These products have already reported in the literature as harmful to the grain vigor of wheat (Abati et al 2014, Baldini et al 2018, and, in the case of maize, were already pointed out capable of interfering with the accuracy of physiological tests to estimate the crop emergence in the field (Pereira et al 2019).…”

The objective of this work was to investigate, before and after chemical treatment, the interrelationships of the physiological quality tests in wheat grains. Following the chemical treatments with (i) carboxin thiram; (ii) carboxin thiram + thiamethoxam; (iii) carboxin thiram + thiamethoxam + bio-stimulant; (iv) pyraclostrobin + methyl thiophanate + fipronil, and (v) pyraclostrobin + methyl thiophanate + fipronil + bio-stimulant, subsequently the grains were assessed for their physiological potential. The physiological potential of the grains could be differentiated based on the electrical conductivity, seedling growth, and emergence in sand tests. In conclusion, the use of the active ingredients changed the correlation between laboratory tests with crop emergence in the sand as well as altered the relevance of the tests for sorting the treated grains into different physiological potential. But, the seedling growth tests and the electrical conductivity were, together, the parameters most relevant for explaining the data variability.

“…Esquema detalhado dos tratamentos industriais de sementes de soja com seus respectivos períodos de armazenamento. Após o tratamento das sementes, a qualidade fisiológica das sementes foi avaliada por meio dos seguintes testes: teste de germinação (De Sementes, 2009), teste primeira contagem da germinação (De Sementes, 2009), comprimento da parte aérea (Abati et al, 2014), comprimento da planta inteira (Abati et al, 2014), comprimento de raiz (Abati et al, 2014), índice de velocidade de emergência (Nakagawa, 1994), emergência final (Pereira, et al 2019), teste de envelhecimento acelerado (Marcos Filho 1999).…”

O tratamento industrial de sementes (TSI) que visa a proteção da sementes afim de garantir o máximo potencial das sementes no campo. O presente trabalho avaliar o potencial fisiológico de sementes de soja em diferentes períodos de armazenamento, após a aplicação de caldas à base de misturas com micronutrientes e biorreguladores. Foram utilizados 2,5 kg de sementes da cultivar BMX Alvo RR. O experimento foi conduzido em delineamento inteiramente casualizado com 4 repetições, 4 tratamentos e 6 períodos de armazenamento. Os tratamentos foram corresponderam a testemunha (T1), micronutriente + polímero + pó secante (T2), bioregulador + polímero + pó secante (T3) e micronutriente + bioregulador + polímero + pó secante (T4). Os períodos em que a sementes foram armazenadas corresponderam a: 0, 15, 30, 45, 60 e 90. As variáveis germinação, primeira contagem, envelhecimento acelerado, índice de velocidade de emergência, emergência final no substrato areia, comprimento da parte aérea, comprimento da raiz e comprimento total foram avaliadas em cada período de armazenamento. O potencial fisiológico de sementes de soja é afetado pelo número de produtos fitossanitários adicionados às caldas no TSI. O período de armazenamento associado ao elevado volume de calda reduziram a qualidade e vigor das sementes para todas a variáveis avaliadas.Palavras-chave: Bioestimulante, germinação, Glycine max (L), volume de calda.

“…With regard to electrical conductivity or potassium leakage, Miguel and Marcos Filho (2002), Pereira et al (2019), Sharma et al (2011), and Zucareli et al (2013), among other authors, report high degrees of correlation between those tests, when applied to seeds, and the subsequent performance observed at field condition.…”

The objective of this work was to compare the accuracy of seedling tests based on electrolyte release to distinguish different maize seed vigor levels with the accuracy provided by biometric tests for seedling length and biomass. For this purpose, seeds with different vigor levels of the Garra Viptera hybrid had their physiological potential evaluated through tests of germination, accelerated aging, seed electrical conductivity, field emergence, seedling length, seedling dry biomass, seedling electrical conductivity, potassium leakage and membrane injury index. Completely randomized design was used, with four replications, except for the field emergence variable, when the randomized complete block design was adopted. The obtained means were compared by Fisher's LSD test, at 5% probability, and then Pearson’s correlation coefficients were calculated between the tests based on seedling performance and the physiological quality results obtained with the seeds. In addition to their lower sensitivity to istinguish the different vigor levels, the biometric tests (length and biomass) showed values of correlation with field emergence considerably lower than those btained with the membrane permeability tests (seedling electrical conductivity, otassium leakage and membrane injury index). Among the tests based on electrolyte extravasation, the membrane injury index was the most accurate to differentiate maize seed lots in different vigor levels, as well as to estimate the seed emergence in the field.
