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 ...
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 ...
Temperature-dependent regulation of induction into secondary dormancy of Polygonum aviculare L. seeds: A quantitative analysis
(Elsevier Science, 2017-05)
In seeds of many summer annuals low temperatures under moist conditions provoke dormancy release while high temperatures induce secondary dormancy. Seed dormancy level establishes the range of temperatures under which ...
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 ...
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 ...
Cambial dormancy lasts 9Â months in a tropical evergreen species
(2016-08-01)
Key message: Cambial dormancy in a tropical evergreen species is long lasting, and the initiation of cambial activity is related to day length. Abstract: Studies on cambial activity allow us to understand the growth dynamics ...
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 ...
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 ...
Light sensitivity changes during dormancy induction in Polygonum aviculare L. seeds: development of a predictive model of annual changes in seed-bank light sensitivity in relation to soil temperature
(Wiley Blackwell Publishing, Inc, 2020-12)
Seeds of weed species require light to terminate dormancy and give way to germination. It is documented that sensitivity to light in Polygonum aviculare seeds increases during dormancy release. However, it is not known ...
Understanding dormancy breakage and germination ecology of Cynara cardunculus (Asteraceae)
(Wiley Blackwell Publishing, Inc, 2018-12)
Cynara cardunculus is a troublesome weed in temperate grazing lands. Cynara cardunculus achenes are usually dormant at dispersal and require alternating temperatures to terminate dormancy and germinate. Laboratory and ...
