G. aPhotoperiod and temperature on seed germination of passion fruit 'SCS437 Catarina'.h[electronic resource] c2023 aThe passion fruit (Passiflora edulis Sims.) propagates by sexual reproduction and presents slow and uneven seed germination. This work has the goal of identifying a temperature and photoperiod that provide greater germination of the cultivar SCS 437 Catarina. We used an entirely randomized experimental design in a 2 x 3 + 1 factorial: two temperatures (alternating between 20/30 ºC and constant 25 ºC) and three photoperiods (8/16 ? 8 hours of light and 16 hours of darkness; 12/12 ? 12 hours of light and 12 hours of darkness; and absence of light), and for alternating temperature, an absence of light treatment was added, being classified as neutral photoblastic, and at a constant temperature of 25 ºC made germination unfeasible, while the 20/30 ºC alternating temperatures provided an average germination of 75%. The seeds showed an indifferent behavior to light, and the temperature alternated with 12/12 h photoperiod was the ideal condition to promote a higher percentage of germination. aabiotic factors agerminability aPassiflora edulis Sims aphotoblastic1 aSCHWARZ, S.
