Crop Stress Physiology – Københavns Universitet

Gruppen Crop Stress Physiology fokuserer på den fysiologiske og biokemiske regulering af vækst og funktion i afgrøder udsat for abiotiske belastninger, herunder tørke, varme, kulde, salt og lys. Vi har rettet meget opmærksomhed på den relative betydning af hydrauliske og kemiske påvirkninger på afgrødernes vegetative og reproduktive fysiologi under tørke / varmestress.

Vores forskning har til formål at forbedre afgrødernes udbytte og kvalitet samt ressource / energiforbruget i mark- og drivhusproduktionssystemer, ved at udnytte planternes mekanismer til tilpasning af miljøforstyrrelser i et fremtidigt varmere, tørrere og CO2-berigede klima. Til drivhusproduktion arbejder vi på ressourceminimering igennem dynamisk klimakontrol, hvor alle klimaparametre, herunder forhøjet CO2, integreres.

Forskningstemaer

  • Crop physiological responses to abiotic stresses including drought, heat, cold, salinity and light stresses

  • Biological water-saving irrigation strategies

  • Crop nutrient (N, P) use efficiency, and the roles of biochar amendment and controlled soil water dynamics in improving soil N and P bioavailability

  • Effects of elevated CO2 on stomatal response to drought and heat stress as well as C and N metabolisms in source and sink organs

  • Effect of inoculation of mycorrhiza/plant growth-promoting rhizobacterial endophytes on crop C and N dynamics and tolerance to abiotic stresses

  • Effect of canopy density and climate parameters on crop transpiration in pot plants and how it relates to acclimation of stomatal density and regulation

  • Physiological effect of the spectral composition of light on plant growth and morphology during propagation and early development of pot plants

  • The role of photorespiration in the temperature response of photosynthesis
