- Abstract
The objective was to evaluate the growth of Japanese hybrid cucumber seedlings submitted to the variation of temperature and radiation. The experiment was conducted at the Genetic Improvement and Plant Production Laboratory of the Federal University of Santa Maria, Campus of Frederico Westphalen, Rio Grande do Sul. It was used a randomized block design, arranged in a factorial arrangement, made up of two (environments) x 30 (days of evaluation), arranged in five replications. The environments were characterized by a growth chamber with photoperiod and controlled temperature, and environment with temperature and natural light conditions. The evaluations were performed daily for the period of 30 days in five plants of each environment, with respect to the: number of leaves, plant height, root length, stem diameter, green shoot biomass, green root biomass, dry shoot biomass, dry root biomass and leaf area. The results showed that temperatures below 15℃ limited the growth of seedlings, especially when they are still dependent upon energy stocks located in the cotyledons. Radiation levels below 100 W m² s-1 reduce the leaf area and the emission rate of new leaves.
