Análise de imagens de plântulas para avaliação do potencial fisiológico de sementes de berinjela
Provedor de dados: 75
Autores: Silva,Vanessa N; Cicero,Silvio M.
A automatização da análise do crescimento de plântulas pelo uso de processamento computadorizado de imagens pode contribuir para avaliação do vigor de sementes. O objetivo deste trabalho foi verificar a possibilidade de utilização do sistema computadorizado de análise de imagens de plântulas (SVIS, Seed Vigor Imaging System) para detectar diferenças de vigor entre lotes de sementes de berinjela em comparação às informações fornecidas por testes de vigor tradicionalmente utilizados. Dez lotes de sementes de berinjela, cultivar Embu, foram armazenados por 12 meses em sala com ambiente controlado a 20±1°C e 45-50% de umidade relativa do ar. O teor de água das sementes foi monitorado e o potencial fisiológico avaliado aos 0, 6 e 12 meses após o armazenamento,...

Image seedling analysis to evaluate tomato seed physiological potential
Provedor de dados: 124
Autores: Silva,Vanessa Neumann; Cicero,Silvio Moure.
Computerized seedling image analysis are one of the most recently techniques to detect differences of vigor between seed lots. The aim of this study was verify the hability of computerized seedling image analysis by SVIS® to detect differences of vigor between tomato seed lots as information provided by traditionally vigor tests. Ten lots of tomato seeds, cultivar Santa Clara, were stored for 12 months in controlled environment at 20 ± 1 ºC and 45-50% of relative humidity of the air. The moisture content of the seeds was monitored and the physiological potential tested at 0, 6 and 12 months after storage, with germination test, first count of germination, traditional accelerated ageing and with saturated salt solution, electrical conductivity, seedling...

Recent approaches for bell pepper seed vigor testing
Provedor de dados: 1
Autores: Dias, Marcos Altomani Neves; Mondo, Vitor Henrique Vaz; Cicero, Silvio Moure.
Seed vigor is a major attribute in the determination of whether a seed lot can be commercialized. Different physiological tests are used to assess seed vigor and are generally based on different concepts, which could lead to variable interpretations, particularly when comparing lots presenting different vigor levels. This study was conducted to compare the different approaches used to evaluate bell pepper seed vigor and verify the applicability of the Seed Vigor Imaging System (SVIS) for this purpose. The experiment was performed using four seed lots of bell pepper hybrids in two periods, and the evaluations involved germination, seedling emergence, seedling emergence speed index, saturated salt accelerated aging and image analysis. The use of seedling...
