Plant responses to light quality are specific to the specie (Hernández and Kubota 2014). Cucumber transplants
grow with and without supplemental light-emitting diodes lighting different blue: red photon flux ratios. Under
different solar daily light integrals, it didn’t show benefits in crop growth and morphology with the increase of blue
photon flux. Moreover, cucumber showed a decrease in dry mass, leaves number and leaf area with the increase of
blue photons flux conditions. Xiong et al. (2011) noticed a significant interaction between difference of day/night
temperature and end-of-day light quality. It was found on morphology, dry matter and carbohydrate content in axial
plant organs like stems and petioles, but not in leaf blades and roots.
The aim of the present work is to quantify the effect of different pruning procedures on: 1. some physiological
processes on cucumbers leaves grown in solarium; 2. cucumber plants growth and development as well as the fruit
yield.
