Chill-induced inhibition of photosynthesis: genotypic variation within Cucumis sativus.

Abstract excerpt

Cucumber is generally a thermophilic species; however, cultivars have been selected for higher yield during winter cultivation in unheated glasshouses in temperate regions. We tested whether photosynthesis in these varieties had greater chilling tolerance. There was no difference in the instantaneous reduction of photosynthesis at low temperature between four winter glasshouse and four summer field cultivars....
