In a quality control program, seed vigor evaluation is of fundamental importance for the success of the program. The objective of this project was to evaluate the efficiency of several vigor tests to evaluate the physiological ...
Sementes de guandu, produzidas em semeadura tardia: efeito de doses de fósforo, potássio e espaçamentos
(Universidade Estadual de Maringá (UEM), Pro-reitoria Pesquisa Pos-graduacao, 2008-10-01)
The objective of this work was to evaluate the effects of five P(2)O(5) rates and four K(2)O rates in two inter row plant spacings on the quality of short-duration pigeonpea seeds, in Selviria, Mato Grosso do Sul State, ...
Electrical conductivity of the seed soaking solution and soybean seedling emergence
(Universidade de São Paulo (USP), 2004-03-01)
Vigor of soybean [Glycine max (L.) Merrill] seeds can be evaluated by measuring the electrical conductivity (EC) of the seed soaking solution, which has shown a satisfactory relationship with field seedling emergence, but ...
Effects of litter on seedling establishment in natural and semi-natural grasslands: a meta-analysis
(Wiley, 2013-03)
1 Plant litter is a key component in terrestrial ecosystems. It plays a major role in nutrient cycles and community organization. Land use and climate change may change the accumulation of litter in herbaceous ecosystems ...
Teste de condutividade elétrica para sementes de mamoneira
(Universidade Estadual de Londrina (UEL), 2009-01-01)
The aim was to study the efficiency of electrical conductivity test in evaluating the quality of castor seeds. Emergence of seedlings was evaluated in the field, with five seed lots of cv. AL Guarany 2002. The seeds were ...

(Universidade de São Paulo (USP), Escola Superior de Agricultura Luiz de Queiroz (ESALQ), 2004-10-01)
Informações sobre a relação entre resultados de testes de vigor conduzidos em laboratório e da emergência de plântulas em campo são fundamentais para a tomada de decisões pelos produtores de sementes. O presente trabalho ...
TESTS FOR THE SELECTION OF FORAGE TURNIP PROGENY TO ORDER THE VIGOR AND LONGEVITY OF SEEDS
(Univ Fed Rural Semi-arido-ufersa, 2017-01-01)
Forage turnip (Raphanus sativus L. var. oleiferus Metzg.) progeny with seeds of higher physiological quality are of importance for farmers and seed producing companies. The objective of this work was to identify tests to ...
Methodology for the selection of soybean strains for germination, vigour and field emergence
(Univ Federal Ceara, Dept Geol, 2016-07-01)
Soybean cultivars with seeds of higher physiological quality are of interest to farmers and seed companies. The aim of this study therefore, was to verify the genetic variability and the relationship that exists between ...
Correlation of electrical conductivity and other vigor tests with field emergence of soybean seedlings
(1999-01-01)
Seeds from six soybean cultivars (Cristalina, IAC 31-Foscarin, IAC-15, UFV-10, IAC-14 and IAS-5) and from five soybean cultivars (IAC 31-Foscarin, IAC-15, IAC-14, IAS-5 and Iguacu) were evaluated in 1993 and 1994, respectively, ...
