Os modelos hydrotime e hydrothermal time na análise da germinação em função da temperatura e potencial de água
(2013-12-01)
Many studies on seed germination are carried out testing the effect of environmental factors, particularly water and temperature which are considered the main factors for successfully germination. Moreover, in most of these ...
Thermal regulation of secondary dormancy induction in Polygonum aviculare seeds: A quantitative analysis using the hydrotime model
(Cambridge University Press, 2017-09)
For seed banks showing seasonal changes in their dormancy level, the possibility of predicting temporal patterns of emergence depends on establishing a robust relationship between temperature and the rate of dormancy loss ...
O modelo 'hydrotime' pode descrever a resposta de sementes de feijão comum (phaseolus vulgaris l.) à temperatura e potenciais de água reduzidos
(2013-05-13)
Germination parameters of the response to temperature and water potential from four common bean (Phaseolus vulgaris) lines based on thermal-time and hydrotime concepts were estimated to verify to what extent they can predict ...

Germination responses to temperature and water potential in Jatropha curcas seeds: A hydrotime model explains the difference between dormancy expression and dormancy induction at different incubation temperatures
(Oxford University Press, 2012-01)
•Background and Aims: Jatropha curcas is a drought-resistant tree whose seeds are a good source of oil that can be used for producing biodiesel. A successful crop establishment depends on a rapid and uniform germination ...
Effect of reduced water potential on seed germination of a forest tree: A hydrotime approachEfeito da redução do potencial hídrico na germinação de sementes de uma árvore tropical: Uma abordagem do tempo hídrico
(2020-01-01)
Hydrotime (θH) models provide information on seed tolerance to low water potential and time to germination under different conditions. Here it was evaluated the capacity of graphic and probit model to describe germination ...
Germination response to water availability in populations of Festuca pallescens along a Patagonian rainfall gradient based on hydrotime model parameters
(Nature, 2021-12)
Sensitivity to water availability is a key physiological trait for grassland species located in arid and semiarid environments, where successful germination is closely related to rainfall dynamics. Festuca pallescens ...

Germinação de sementes de Drymaria cordata (L.) Willd. ex Roem & Schult.: efeito do potencial hídrico
(Sociedade Botânica de São Paulo, 2008-06-01)
Modelos matemáticos baseados no conceito de graus dia (thermal-time) e Ψw dia (hydrotime) podem ser usados para a elaboração de modelos mais gerais sobre a germinação e emergência de plântulas no campo, podendo ser uma ...
