DORMANCY IN YAMS

open access: yesExperimental Agriculture, 2001
The tubers of yam, principally those of Dioscorea rotundata (white Guinea yam) and D. alata (water or greater yam), are important staple foods and sources of carbohydrate in West Africa. Yams are grown in diverse environments – from the high-rainfall forest zone on the coast to the seasonally arid savannas of West Africa, that is in situations in which

Growing apple (Malus domestica) under tropical mountain climate conditions in Northern Ethiopia [PDF]

open access: yes, 2010
Lack of effective chilling during the dormant season is one of the major problems when apples are growing under a tropical climate. We evaluated the response of different apple cultivars (Golden Delicious, Gala, Fuji, Granny Smith and Jonagold) grown on ...

A Thermal Time Basis for Comparing the Germination Requirements of Alfalfa Cultivars with Different Fall Dormancy Ratings

open access: yesAgronomy, 2023
Fall dormancy plays important roles in the evaluation of alfalfa’s winter hardiness and in the selection of alfalfa breeding. A rapid and effective method to estimate the fall dormancy rating of alfalfa will shorten the breeding cycle.

Temperature, light and nitrate sensing coordinate Arabidopsis seed dormancy cycling resulting in winter and summer annual phenotypes [PDF]

open access: yes, 2013
Seeds use environmental cues to sense the seasons and their surroundings to initiate the plants life cycle. Dormancy cycling underlying this process is extensively described, but the molecular mechanism is largely unknown.

The signalling role of ROS in the regulation of seed germination and dormancy.

open access: yesBiochemical Journal, 2019
Reactive oxygen species (ROS) are versatile compounds which can have toxic or signalling effects in a wide range living organisms, including seeds. They have been reported to play a pivotal role in the regulation of seed germination and dormancy but ...

Evaluation of dormancy break in some selected peach (Prunus persica) cultivars

open access: yesHorticultural Science, 2016
The evaluation of dormancy break based on the number of flower buds in bloom was performed in years 2011-2013 (January-April) for 15 peach cultivars compared to the control cv. Redhaven.

A Conceptual Framework for Winter Dormancy in Deciduous Trees

open access: yes, 2020
The perennial life strategy of temperate trees relies on establishing a dormant stage during winter to survive unfavorable conditions. To overcome this dormant stage, trees require cool (i.e., chilling) temperatures as an environmental cue.

Sowing seeds for the future: the need for establishing protocols for the study of seed dormancy

open access: yesActa Botânica Brasílica, 2013
Seed dormancy is a widely misunderstood plant trait. In several research areas, a lack of germination is wrongly assumed to result from seed dormancy. In an attempt to standardize seed dormancy research and improve communication among seed scientists, a ...

The DAG1 transcription factor negatively regulates the seed-to-seedling transition in Arabidopsis acting on ABA and GA levels [PDF]

open access: yes, 2016
BACKGROUND: In seeds, the transition from dormancy to germination is regulated by abscisic acid (ABA) and gibberellins (GAs), and involves chromatin remodelling.

A Two-Stage Culture Method for Zygotic Embryos Effectively Overcomes Constraints Imposed by Hypocotyl and Epicotyl Seed Dormancy in Paeonia ostii ‘Fengdan’

open access: yesPlants, 2019
The effect of the exogenous hormone and light quality on breaking hypocotyl and epicotyl dormancy was studied. The results showed that the greatest percentage of hypocotyl dormancy breaking was observed with the Murashige and Skoog (MS) medium ...
