The epiphytic Cactaceae Hylocereus setaceus (Salm-Dick ex DC.) ralf bauer seed germination is controlled by light and temperature
2007
Brazilian Archives of Biology and Technology
The effect of light and temperature on seed germination in Hylocereus setaceus was analyzed by isothermic incubations under continuous white light and darkness. The minimum temperature for germination was between 5 to 10°C and the maximum between 45 to 50°C. The optimum temperaturewais between 25 and 30°C. The involvement of phytochrome, by very low fluence response, in controlled seed germination was attained by incubation in a gradient of photoequilibrium of phytochrome. The results indicated
