Effects of Wounding on Cytokinin Activity in Cucumber Cotyledons

PMCID: PMC1056275  PMID: 16665151

Abstract

Three known physiological responses to exogenous cytokinins were measured in wounded and nonwounded cotyledons from cucumber (Cucumis sativus L. cv Marketer) seedlings grown in darkness. Enhanced cell division, chlorophyll formation, and cotyledon expansion were detected in wounded cotyledons. The data suggest that wounding enhances endogenous cytokinin activity.
