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 ...
Effect of water availability and seed source on physical dormancy break of Vicia villosa ssp. villosa
(2016-09)
Physical dormancy (PY) plays a crucial role in the control of the reseeding process of Vicia villosa Roth, a winter annual species cultivated for pasture and hay, naturalized in several semi-arid temperate agroecosystems. ...
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 ...
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 ...
Environmental control of dormancy in quinoa (Chenopodium quinoa) seeds: Two potential genetic resources for pre-harvest sprouting tolerance
(Cambridge University Press, 2011-06)
Pre-harvest sprouting (PHS) is a serious risk when adapting quinoa (Chenopodium quinoa) seed production to different temperate environments. Two quinoa accessions, 2-Want and Chadmo were evaluated under field conditions ...
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 ...
Role of relative humidity, temperature, and water status in dormancy alleviation of sunflower seeds during dry after-ripening
(Oxford University Press, 2011-01)
The effect of various combinations of temperature and relative humidity on dormancy alleviation of sunflower seeds during dry after-ripening was investigated. The rate of dormancy alleviation depended on both temperature ...
The rffect of einter lLength on duration of dormancy and survival of Rhagoletis completa (Diptera: Tephritidae) and associated parasitoids from Northeastern Mexico
(University of Arizona, 2019-05)
The walnut husk fly Rhagoletis completa (Cresson), native to the Midwestern United States and Mexico, is invasive in California and Europe. It is one of the most important pests of walnuts in areas gathering 30% of the ...
