Dormancy cycling in Polygonum aviculare seeds is accompanied by changes in ABA sensitivity
(Oxford University Press, 2020-07)
Polygonum aviculare seeds shows high levels of primary dormancy (PD). Low winter temperatures alleviate dormancy and high spring temperatures induce seeds into secondary dormancy (SD), naturally establishing stable seedbanks ...
Molecular mechanisms underlying the entrance in secondary dormancy of Arabidopsis seeds
(Wiley, 2016-01)
As seasons change, dormant seeds cycle through dormant states until the environmental conditions are favourable for seedling establishment. Dormancy cycle is widespread in the plant kingdom allowing the seeds to display ...
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 ...
The role of seed water content for the perception of temperature signals that drive dormancy changes in Polygonum aviculare buried seeds
(Csiro Publishing, 2020-08)
Seedling emergence in the field is strongly related to the dynamics of dormancy release and induction of the seed bank, which is mainly regulated by soil temperature. However, there is limited information on how ...
Echinochloa crus-galli seed physiological dormancy and germination responses to hypoxic floodwaters
(Wiley Blackwell Publishing, Inc, 2019-07-06)
Hypoxic floodwaters can seriously damage seedlings. Seed dormancy could be an effective trait to avoid lethal underwater germination. This research aimed to discover novel adaptive dormancy responses to hypoxic floodwaters ...
Pre-harvest sprouting and grain dormancy in sorghum bicolor: What have we learned?
(Frontiers Media S.A., 2018-06)
The possibility of obtaining sorghum grains with quality to match the standards for a diversity of end-uses is frequently hampered by the susceptibility to pre-harvest sprouting (PHS) displayed by many elite genotypes. For ...
Effect of FLOWERING LOCUS C on seed germination depends on dormancy
(Csiro Publishing, 2017-03)
FLOWERING LOCUS C (FLC) has a major regulatory role in the timing of flowering in Arabidopsis thaliana (L.) Heynh. and has more recently been shown to influence germination. Here, we investigated the conditions under which ...
Germination parameterization and development of an after-ripening thermal-time model for primary dormancy release of Lithospermum arvense seeds
(Oxford University Press, 2009-06)
Models based on thermal-time approaches have been a useful tool for characterizing and predicting seed germination and dormancy release in relation to time and temperature. The aims of the present work were to evaluate the ...
A stratification thermal time-based model as a tool for designing efficient methodologies to overcome seed dormancy constraints to kiwifruit seedling production
(Elsevier Science, 2021-02)
Kiwifruit (Actinidia deliciosa A. Chev. C.F. Liang and A.R. Ferguson) seedling production in the nursery is usually impaired because of low seed germination resulting from primary dormancy. Dormancy of hydrated seeds is ...
A plurality of causal mechanisms explains the persistence or transience of soil seed banks
(Academic Press Ltd - Elsevier Science Ltd, 2010-02)
Annual forbs form short-term persistent soil seed banks whereas perennial grasses form mostly transient ones in the central Monte desert. A conceptual framework predicts that annual forb seeds will have primary dormancy, ...
