“…treatments with highest germination percentages, 57, 60 and 60%, respectively. Corroborating with our results, Rezazadeh and Stafne (2018) evaluating four different pre-germination treatments to increase the germination potential of seven Passiflora species, concluded that the scarification associated with imbibition in 1000 mg L -1 GA 3 for 24 hours were efficient to increase the germination percentage of P. maliformis and P. tripartita var. mollissima.…”

The knowledge about aspects related to seed germination are extremely important to the propagation of Passiflora species. Considering the diversity of Passiflora species and the need of studies that can elucidate the germination process of Passiflora seeds this study aimed was to evaluate methods to overcome seed dormancy in two Passiflora species (P. morifolia and P. cincinnata) by pre-germinative treatments as physical scarification, immersion in gibberellic acid (GA 3 ) and Promalin ® (GA 4+7 + N-(phenylmethyl) -aminopurine). To dormancy overcoming, the pre-germinative treatments were: scarification in sandpaper; immersion in water at 50 ºC for 5 minutes; imbibition in 400, 1000, 2000 and 3000 mg L -1 GA 3 for 5 hours; scarification in sandpaper + imbibition in 400, 1000, 2000 and 3000 mg L -1 GA 3 for 5 hours; and imbibition in 0.03, 0.45, 0.90 and 2% Promalin ® for 6 and 12 hours. The treatments were distributed in a completely randomized design, with four repetitions of 25 seeds. The data were submitted to variance analysis and the averages compared by Tukey test and Scott-Knott, respectively, at 5% of probability using the software SISVAR. Germinability, germination time, germination velocity, uncertainty and germination synchrony were evaluated. The results showed that 0.45, 0.90 and 2% Promalin ® for 6 and 12 hours were effective to overcome the seed dormancy in P. cincinnata. The treatment 1000 mg L-1 GA 3 achieved the highest result to overcome the dormancy in P. morifolia seeds.

“…According to the species of the genus Passiflora, there may be a better germinative response to specific treatments. Conforming to Rezazadeh et al (2018), the best germination performances were obtained with the combination of the following treatments: scarification and fermentation for P. laurifolia; scarification and use of GA3 for P. maliformis seeds and immersion in water or scarification and use of GA3 for P. tripartita var. mollissima.…”

“…For instance, there is physical dormancy in seeds of P. laurifolia (Rezazadeh et al, 2018) and P. maliformis (Torres-G, 2018), physiological dormancy in seeds of P. elegans (Silva et al, 2019) and P. suberosa (Oliveira et al, 2020) and physicophysiological dormancy in seeds of P. actinia (Grzybowski et al, 2019) and P. mollissima (Delanoy et al, 2006).…”

setacea seeds without aril, were submitted to pre-germination treatments: T1(control); T2 (pre-soaking in Promalin® solution [gibberellin (GA4+7) + N-(phenylmethyl)-1H-purine 6-amine (6-benzyladenine) both at a concentration of 18.8 g.L-1] in bainMarie, 45 °C/20 min.; T3 (osmopriming with KNO3 at a concentration of 2.6g.L-1 H2O, 25 °C/1 day, with aeration); T4 (osmopriming with KNO3 at a concentration of 2.6g.L- 1 H2O, 25 °C/2 days, with aeration); T5 (T3 followed by T2) and T6 (T4 followed by T2). The initial moisture contents, ranging from 6.7% to 8% did not differ from each other (α 0.05). The highest fresh mass increment at 168h and the highest moisture content at the end of the germination test were achieved by T2, 40.9% and 44.3%, respectively. The lowest fresh mass increment at 168h was T1 (13.1%). Osmopriming with KNO3 and aeration contributed to better water absorption in T3 and T4 than in T1, but did not stimulate the germination performance of the seeds. The highest germination percentages and germination speed indexes were obtained from T2 seeds (92% and 8, 4595), T5 (96% and 11.7438) and T6 (94% and 11.6728) as well as the lowest mean germination times T2 (11.73 days), T5 (9.49 days) and T6 (8 .81 days), which did not differ statistically from each other (α 0.05). However, the germination process took less time for T2 seeds, 21 days. The combination of aryl removal and phytohormone solution in a bain-marie at 45 °C/20min. with or without osmopriming with KNO3 stimulated the germination process of P. setacea seeds.

“…Most species are herbaceous, perennial vines with a rapid growth rate. Some of them like maypop (P. incarnata) are considered weeds due to their rampant growth" [1]. "Passion fruit is botanically called as Passiflora edulis belongs to the family passifloraceae and found in tropical America (Brazil).…”

The present study was carried out to investigate the effect of light and GA3 on the germination of purple passion fruit (Passiflora edulis sims) under agro climatic condition of Prayagraj. The perforated polythene bags of 4 x 5 cm size (150 gauges thickness) were used for sowing. The bags were filled with a mixture of farmyard manure (FYM), sand and soil in the ratio of 1:1:1. Pre-sowing-dip method was adopted for seed treatment.The treatments included application of [T0: Shade net(light 20,100), T1: GA3 200 ppm + light 24,500 lux,T2:GA3 200 ppm + light 30,100 lux,T3: GA3 250 ppm + light 24,500 lux,T4:GA3 250 ppm + light 30,100 lux, T5: GA3 300 ppm + light 24,500 lux,T6: GA3 300 ppm + light 30,100 lux,T7:GA3 350 ppm + light 24,500 lux, T8: GA3 350 ppm + light 30,100 lux]. The experiment was laid in randomized block design with nine treatments and was replicated three times. Treatment T8 performed best in term day to 1st germination(20.01), day to 50% germination(26.68), day to complete germination(35.25),germination percentage(89.09), seed vigour index (1400.48),seedling height(10,20,30,40 days) (10.37,11.50,13.69,16.25), number of leaves (10,20,30,40 days) (3.00,4.78,6.22,9.45), shoot length (10,20,30,40 days) (4.68,4.97, 5.05,5.20), root length(10.66), shoot: root(0.62),stem girth(2.70),chlorophyll content (43.37) and survivality percentage(83.65).
