“…P. edulis, although showing the lowest NL, has higher TLA, with superiority of 163.71 and 58.38% in relation to P. cincinnata and P. gibertii, respectively ( Figure 2B). This result differs from that obtained by Sousa et al (2013) in the Passiflora species P. edulis, P. alata and P. ligularis. These authors observed significant difference for NL between the species at 70 days after transplanting.…”

ABSTRACT:The genus Passiflora of the passion fruit crop is the most important from economic point of view. However, its cultivation in the semi-arid region is at risk due to salinity problems, requiring the identification of tolerant species, which develop better in environments with salinity problems. The objective of this study was to evaluate the effects of water salinity on growth and formation of seedlings of three species from the genus Passiflora. The treatments were distributed in a completely randomized design, adopting a 5 x 3 factorial arrangement, with five levels of irrigation water salinity (ECw) of 0.3; 1.4; 2.5; 3.6 and 4.7 dS m -1 and three species of Passiflora: gibertii; cincinnata and edulis 'BRS Gigante Amarelo', with four replicates. P. edulis surpassed the others in leaf area, shoot, root and total dry matter and Dickson index of seedling quality. Irrigation water salinity inhibits the formation of seedlings evaluated by growth in height, stem diameter and shoot, root and total dry matter of the studied species of Passiflora. The interaction between ECw and the Passiflora species interfered significantly in height, root, shoot and total dry matter and Dickson quality index. ECw above 0.3 dS m -1 affects the Dickson quality index of P. gibertii more,compared with P. edulis and P. cincinnata.

“…Among these, vermicompost and coconut powder stand out as efficient, low‐cost, and easily purchasable organic inputs . The use of organic fertilizers is a common practice in the cultivation of yellow passion fruit ( Passiflora edulis f. flavicarpa ), reducing the application of chemical inputs, promoting the development of microorganisms, such as arbuscular mycorrhizal fungi (AMF), and affording an increase in the synthesis of bioactive agents, such as phenolic compounds …”

Use of mycorrhizal fungi releases the application of organic fertilizers to increase the production of leaf vitexin in yellow passion fruit

BACKGROUND: Low-cost organic fertilizers, such as coconut powder and vermicompost, and arbuscular mycorrhizal fungi (AMF) may benefit the Passiflora edulis f. flavicarpa plant. However, it has not been established whether the joint application of these inputs may increase the production of vitexin and other molecules associated with the phytotherapeutic properties of this plant. Here, we tested the hypothesis that the application of AMF and organic fertilizers maximizes the production of bioactive compounds in leaves of P. edulis. RESULTS: The inoculation of Acaulospora longula into P. edulis grown in fertilization-free soil promoted an increase of 86% in the concentration of leaf vitexin, 10.29% in the concentration of total phenols, and 13.78% in the concentration of total tannins in relation to the AMF-free control, rendering soil fertilization superfluous.CONCLUSION: The application of A. longula increases the production of foliar biomolecules, such as vitexin, in yellow passion fruit plants. Thus, the addition of coconut powder and vermicompost to the substrate composition is not necessary, leading to the commercialized production of phytomass in the herbal medicines industry.

“…Among the treatments applied, the growth characteristics showed significant difference by the F test in at least one evaluation period (34, 41, 49, and 58 days after planting), except for the number of leaves (Figure 1 a), which did not differ in any of the evaluations. Other authors found no differences in the production of leaves in passion fruit seedlings in response to fertilization, such as Prates et al (2010) and Sousa et al (2013), at 70 days after sowing, since it is a genetic trait and, hence, more difficult to be changed. ) clearly showed no difference between treatments at 34 days after sowing.…”

Today, industries are increasingly concerned about the disposal of their waste. One of the proposed solutions to deal with certain wastes is through agriculture in the form of fertilizers. Thus, the objective of this study was to evaluate the effect of liquid tannery sludge as foliar fertilizer on the growth and physiology of passion fruit seedlings. The experiment was conducted in a greenhouse, in a randomized block design with six replications. Six treatments were applied to leaves: tannery sludge diluted in water (132, 263, 395 and 527 mL L-1); only water (control); and the conventional treatment. The following growth characteristics were evaluated: leaf production, plant height, crown diameter, stem diameter, total fresh matter and dry matter of the plants. The physiological characteristics evaluated were the indices chlorophyll, nitrogen balance, flavonoids, anthocyanins, and plant color. The flavonoid index increased in plants that received foliar application of 527 mL L-1 without compromising the other characteristics evaluated. The doses 263, 395 and 527 mL L-1 showed the best results for the growth characteristics, equaling those of the conventional treatments. Foliar application of tannery sludge can be recommended for yellow passion fruit seedlings.
