(2014-01-01)
We evaluated the effect of chemical scarification with sulfuric acid (H2SO4) and periods of pre-soaking (PPe) in a solution of potassium nitrate (KNO3), to overcome dormancy of seed and initial seedlings performance of ...
GERMINATION AND RE-INDUCTION OF DISSECATION TOLERANCE IN SEEDS OF Senna multijuga (RICH.) IRWIN ET BARN
(Centro Pesquisas Florestais, Ufsm, 2016-10-01)
The aims of this study were to verify the effects of different tests in the overcoming dormancy, excellent germination terms, as light and temperature, and the possibility of re-induction of desiccation tolerance in Senna ...
Photoperiod throughout the maternal life cycle, not photoperiod during seed imbibition, influences germination in Arabidopsis thaliana
(Botanical Society of America, 2017-04)
PREMISE OF THE STUDY: Plants adjust their phenology in response to seasonal cues experienced both by their parents and by themselves, and coordinating responses to these cues is necessary for expressing adaptive phenology. ...
The roles of light and pericarp on seed dormancy and germination in feral Raphanus sativus (Brassicaceae)
(Wiley Blackwell Publishing, Inc, 2019-08-19)
The timing of seed germination may determine the success of a weed species in an agroecosystem, and its expression is modulated by environmental conditions, but also by seed physiology and anatomy. The aims of this study ...
