Interference of Environmental Factors with Temperature Effects on Plant Growth:III. Light Intensity

photoperiods at air temperatures of 20, 25, 30, 35 and 40•Žin a growth cabinet. Cucumber seedlings were sown in a plastic container filled with burnt chaff. One day after germination, the seedlings were cultured under their respective light intensities and following results were obtained: 1) Hypocotyl elongation was remarkably affected by light intensity at different temperatures; hypocotyl elongation was inhibited by increased light intensities.
