Le réchauffement climatique diminue-t-il le risque de dégâts par le gel pour les cultures de climat tempéré ?

2014

Does global warming reduce the freezing injury risk to temperate climate crops? Winter crop response to a temperature increase is complex. Recent works point out, for cold climate vegetation, a paradoxical increase in freezing injury in a warming climate. Complementary works are needed to support these results for winter crops in temperate areas. To achieve this goal, five climatic records spanning a fifty years-long period for both daily minimum and maximum temperatures were analyzed with a model predicting frost hardiness and freezing damage for the winter pea crop. The methodological approach was based on three main steps: 1) the climate warming analysis of the 1987/1988 temperature shif…

ABA-independent SnRK2 kinases are involved in plant response to salinity

2013

Un poster a été présenté lors de cet événement SPE IPM CT non renseigné car non soutenu par INRA; International audience; Sucrose non-fermenting 1-Related Protein Kinases type 2 family (known as SnRK2) are important group of kina- ses present in all tested plant species. It is known that all SnRK2 (excluding SnRK2.9) are activated in response to salinity and hyperosmolarity in Arabidopsis thaliana protoplasts after short time of treatment. In plants, they are in- volved in the early responses to drought and salinity. Recently published data indicate that SnRK2.4 plays important role in the maintenance of root system architecture during salt stress and in response to cadmium treatment. It wa…

Adventices : effets directs et indirects du réchauffement

2021

Contexte - Les conditions météorologiques extrêmes (gels, précipitations extrêmes, sécheresses automnale ou printanière) ont tendance à se multiplier, perturbant les pratiques agricoles,entraînant des pertes de rendement ou l’abandon de la culture. Les effets de la hausse des températures ou de l’allongement de l’ensoleillement sont plus marqués sur les dates de récoltepar exemple.Mais peut-on prévoir l’impact de ces changements climatiques sur les espèces adventices ?¾ effets diReCts - Les interactions entre caractéristiques climatiques, pratiques culturales et traits biologiques dechaque espèce rendent les prévisions difficiles. La hausse des températures peut avoir des effets directs sur…
