Journal ArticleDOI
Environmental control of dormancy in weed seed banks in soil
Roberto L. Benech-Arnold,Rodolfo A. Sánchez,Frank Forcella,Betina Claudia Kruk,Claudio M. Ghersa +4 more
TL;DR: The different factors that affect dormancy in weed seed banks in soil are discussed, aiming to set a conceptual basis that will facilitate the construction of predictive models and stress the importance of clarifying the interaction between soil thermal and hydric conditions in the modification of the degree of dormancy of seed populations.
BookDOI
Handbook of Seed Physiology : Applications to Agriculture
TL;DR: This chapter discusses the development of Population-Based Threshold Models to Describe and Predict the Effects of Seedbed Environment on Germination and Seedling Emergence of Crops, and modeling Dormancy Changes in Weed Seed Banks As Affected by the Environment.
Journal ArticleDOI
Dormancy in cereals (not too much, not so little): about the mechanisms behind this trait
María Verónica Rodríguez,Jose M. Barrero,Françoise Corbineau,Frank Gubler,Roberto L. Benech-Arnold +4 more
TL;DR: The antagonism between the plant hormones abscisic acid and gibberellins is instrumental in cereal grains for the inception, expression, release and re-induction of dormancy, however, the way in which this antagonism operates is different for the various species and involves different molecular steps as regulatory sites.
Journal ArticleDOI
Hypoxia interferes with ABA metabolism and increases ABA sensitivity in embryos of dormant barley grains
Roberto L. Benech-Arnold,Nicolás Aníbal Gualano,Juliette Leymarie,Daniel Côme,Françoise Corbineau +4 more
TL;DR: Results suggest that hypoxia, either imposed artificially or by the glumellae, increases embryo sensitivity to ABA and interferes with ABA metabolism in the embryo, thus resulting in dormancy.
Journal ArticleDOI
Predicting changes in dormancy level in weed seed soil banks: Implications for weed management
TL;DR: A conceptual framework is presented as an attempt to understand how the different environmental factors affect dormancy in weed seed banks in soil and how these concepts could be used to develop quantitative models to predict dormancy loss in summer annual weed species.
