Influence of pre-germination treatments on germination dynamics of passion fruit (Passiflora edulis var. flavicarpa) seeds under polyhouse condition

The present investigation, entitled “Influence of pre-germination treatments on germination dynamics of passion fruit (Passiflora edulis var. flavicarpa) seeds under polyhouse condition” was carried out at Hi-Tech Horticulture Park, College of Horticulture, Junagadh Agricultural University, Junagadh during the year 2024. The experiment was laid out in a Completely Randomized Design (CRD) with seven treatments and three repetitions. The seven pre-germination treatments (T) viz., T1-GA3 100 ppm, T2-H2SO4 5%, T3-Thiourea 1%, T4-Mechanical scarification and fermentation for 7 days in 10% Sucrose, T5-Mechanical scarification and GA3 100 ppm, T6-Hot water at 50˚C for 10 minutes, T7-Control. The result of this experiment revealed that among the pre-germination treatments on germination, GA3 100 ppm (T1) was found significantly the maximum germination percentage (97.33%) and the minimum days required for germination (9.07 days).
