“…In previous studies, optimal auxin concentration and source have been observed to vary among species and experiments. Based on previous studies, positive rooting responses were observed in the passion fruit, resulting from both indole-3-butyric acid (IBA) and 1-naphthaleneacetic acid (NAA) treatments, and our auxin rates were selected based on these results (Carvalho Pires et al, 2010;Chaves et al, 2004;Gurung et al, 2015;Sabião, 2013).…”

“…Regardless of the issues, seed propagation is still the main method of passion fruit propagation in commercial production (Kishore et al, 2006). Asexual propagation, usually done by grafting and cuttings, is how to eliminate the genetic variation observed in seed propagation (Carvalho Pires et al, 2010;Chaves et al, 2004;Faleiro et al, 2019;Gurung et al, 2015;Miranda et al, 2009). These plants are clones and thus ''true to type'' to the stock plant from which the cutting or scion was taken.…”

Production of passion fruit (Passiflora sp.) via cuttings is a way to eliminate genetic variation in the crop and also results in a faster establishment time. This could aid producers in increasing production efficiency while maintaining genetic lines. The objective of this research was to evaluate ease of rooting and determine the optimal auxin source for seven species of passion fruit. Semihardwood two-node cuttings were taken from the middle of the parent vine, and auxin treatments were applied to the basal end of the cutting. The cuttings were then stuck to a depth of 1 inch on 20 Aug. 2019. Treatments included three auxin sources and seven passion fruit species. Treatments were set up as a randomized complete block design blocking on species, with 10 single-plant replications per treatment. Data were collected 30 d after sticking cuttings and included percent rooted, total root number, average root length (of the three longest roots, measured in centimeters), root quality (0–5 scale, with 0 = dead and 5 = healthy, vigorous root system), root dry weight (measured in grams), and percent callus. Results showed that passion fruit cuttings receiving a hormone treatment had significantly positive effects on rooting responses, such as increased number, length, quality, and dry weight of roots. Blue passionflower (P. caerulea) was the only species in which hormone treatment did not increase rooting compared with the control. The use of hormone to aid in cutting propagation of passion fruit is recommended, depending on the species being propagated.

“…A propagação por sementes em frutíferas tem sido usada quando os meios de propagação vegetativa apresentam custo alto, como no caso do mamoeiro, coqueiro e maracujazeiro (MATOS, 2016). Para Pires (2011), essa propagação, muitas vezes, é desvantajosa, visto que a utilização de sementes nem sempre assegura a manutenção das características da planta que as forneceu. Assim, é importante o cuidado com qualidade das sementes, buscando aquelas que sejam certificadas, obtidas de plantas matrizes de qualidade comprovada.…”

O presente trabalho teve como objetivo avaliar diferentes métodos de superação de dormência em sementes do maracujá doce (P. alata Curtis). O delineamento experimental adotado foi o inteiramente casualizado, com sete tratamentos e três repetições. Os tratamentos utilizados foram: T1 – testemunha; T2 – imersão em ácido sulfúrico; T3 – imersão em ácido giberélico na concentração de 1000 ppm; T4 – imersão em ácido giberélico na concentração de 3000 ppm; T5 – imersão em água utilizando a 35 °C; T6 – imersão em água a 50 °C; T7 – imersão em ácido clorídrico a 37%. Foram avaliadas a emergência, índice de velocidade de emergência, altura da plântula, diâmetro do caule, comprimento de raiz, número de folhas, massa de matéria fresca e seca. Com base nos resultados, os tratamentos utilizados não foram eficientes para superar a dormência nas sementes de maracujá doce. A imersão de sementes de maracujá doce em água a temperatura de 50 °C por 15 minutos é uma alternativa viável para a melhoria da qualidade fisiológica, sendo necessário o aprimoramento do tempo de imersão e da temperatura adequada.

This study was carried out in two consecutive seasons (2022 and 2023) at the Agricultural Research Center Horticultural Research Institute, Giza, Egypt, where different concentrations of indole butyric acid (IBA) were applied to rooting ability and leaf growth of cuttings. We investigated the effect on the promotion of Vegetative propagation by passion fruit cuttings. These cuttings are from healthy fifth-year mother trees already grown in the Horticultural Laboratory nursery at the Agricultural Research Center in Giza, Egypt. The cut length was 10-14 cm, 3 knots, the trunk thickness was 5-7 mm, and it was made by cutting the upper part obliquely and flattening the lower part. Cuttings, on the other hand, are cleaned by removing the old leaves, except for two new leaves. Rapidly dip the bottom (1-2 cm) of the cuttings into various concentrations of IBA (0, 1000, 2000, and 3000 ppm) for 15-20 seconds. Cuttings planted in medium then contained a mixture of soil + sand + FYM (1:1:1 v/v/v) in a 40 x 60 cm plastic box at a 45-degree angle. These cuttings were planted twice (March and August in both seasons) in a greenhouse under a mist irrigation system and automatically sprayed with water every hour for 5 minutes. The results showed that cuttings treated with 3000 ppm IBA and planted in March had the highest survival rate in both seasons, with improved root number, root length, and shoot and leaf numbers.
