Effect of ozone on photosynthesis and seed yield of sensitive (S156) and resistant (R123) Phaseolus VulgarisL. genotypes in open-top chambers

Scheepers, Cornelius C.W.; Krüger, Gert H.J.; Strasser, Reto J. (Springer, 2013)

Rising tropospheric ozone (O3) concentrations have been identified as a significant threat to crop production. In the present study two snap bean (Phaseolus vulgaris L.) genotypes with known difference in sensitivity to ...
Kontrasterende invloed van chroniese osoonblootstelling op fotosintetiese elektronoordrag en CO2-assimilering in gevoelige (S156) en bestande (R123) Phaseolus vulgaris L. genotipes

Krüger, Gert H. J.; Scheepers, Cornelius C.W.; Strasser, Reto J.; Berner, Jacques M. (Suid-Afrikaans Akademie vir Wetenskap en Kuns, 2018)

Troposferiese osoon (O3) word beskou as een van die belangrikste lugbesoedelstowwe aangesien dit wêreldwyd meer skade aan landbougewasse aanrig as al die ander besoedelstowwe saam. Weens die oksiderende aard daarvan ...
Photosynthetic responses of canola and wheat to elevated levels of CO₂ and O₃ in open-top chambers

Maliba, Bheki George (North-West University (South Africa), 2019)

The concentrations of carbon dioxide (CO2) and ozone (O3) are increasing in the atmosphere. The effects of elevated CO2 (700 ppm), O3 (80 and 120 ppb) and the combination of these two gases on the photosynthetic performance ...
