“…This is because after evaluation at 150 days of slow growth, many plants began to lose their leaves through the natural process of leaf abscission. In addition, passion fruit plants are known to produce higher concentrations of ethylene when grown in vitro (Trevisan & Mendes, 2005;Faria et al, 2017). Ethylene is a Acta Scientiarum.…”

“…Although slow growth is considered a promising method for the conservation of germplasm in Passiflora, difficulties in maintaining seed banks and field collections relate to few available studies in the literature focused on developing protocols for passion fruit species (Faria, Costa, Junghans, Ledo, & Souza, 2006;Garcia, Pacheco, Vianna, & Mansur, 2011;Pacheco et al, 2016;Faria et al, 2017).…”

New evidence for in vitro conservation of nodal segments of the passion fruit ‘UENF Rio Dourado’ (Passiflora edulis Sims)

The germplasm of Passiflora L. is conserved through seed banks and field collections. Dormant seeds, seeds with low viability, and high-cost field collections make it difficult to maintain germplasm banks, and in vitro conservation can be a complementary alternative. The aim of this study was to investigate the survival of nodal segments of Passiflora edulis Sims ‘UENF Rio Dourado’ over 180 days of slow growth in vitro by reducing the mineral salt and sucrose concentrations and changing the incubation conditions (temperature and light intensity). The experiment was conducted in a completely randomized design with a 2 × 3 × 3 factorial arrangement consisting of two temperatures (20 ± 2°C and 27 ± 2°C), three concentrations of MSM mineral salts (100% MSM, 50% MSM, and 25% MSM), and three sucrose concentrations (10, 20, and 30 g L-1). Evaluations were performed at 60, 90, 120, 150, and 180 days for survival, number of leaves, and plant color (using a color scale where 1 = dark green, 2 = light green, and 3 = yellow). After 180 days of culture, mineral salt, sucrose concentration, and incubation temperature affected plant survival, regeneration, and acclimatization. During the 180 days, it was possible to slow the growth of nodal segments of passion fruit ‘UENF Rio Dourado’ in culture medium with 25% MSM mineral salts plus 10 g L-1 sucrose, at an average temperature of 20°C without compromising plant survival, regeneration, and acclimatization.

“…The addition of silver nitrate and cobalt chloride, known ethylene inhibitors, may have led to a lower accumulation of ethylene in the atmosphere inside the culture test tubes, which stimulated the multiplication of Andrographis paniculata (Das & Bandyopadhyay, 2020). This effect was also raised in the production of Passiflora gibertii (Faria et al, 2017) and Glycyrrhiza glabra (Tahoori et al, 2018). Sarropoulou et al (2016), observed direct effects of silver nitrate, silver sulfate and cobalt chloride on the proliferation of shoots in vitro and on the rooting of cherry.…”

The objective was to evaluate plant growth regulators and ethylene inhibitors on the development and leaf abscission of Schinopsis brasiliensis Engl. Zeatin (ZEA) was evaluated in concentrations combined with concentrations of indolacetic acid (IAA), naphthalene acetic acid (NAA) and indolbutyric acid (IBA). ZEA and 6-benzylamino purine (BAP) were evaluated in concentrations plus a control. Ethylene inhibitors, silver nitrate and cobalt chloride were evaluated in four concentrations. The addition of 0.2 μL-1 of NAA to 0.4 μL-1 of ZEA promotes a greater number of baraúna sprouts. At concentrations of 5 and 10 μM, cobalt chloride is more efficient than silver nitrate for reducing leaf abscission in baraúna. IAA is the most suitable auxin to be associated with ZEA for higher shoot length and number of buds. Silver nitrate from a concentration of 20 μM completely avoids leaf abscission while cobalt chloride has a maximum reduction in abscission at a concentration of 40 μM.

“…In this study addition of Ag + ions promoted the flowering induction in rose shoots, but high concentrations resulted in possible toxic effects to flower development. Silver ions acts causing block in ethylene receptors in plants, inhibiting ethylene effects (Santana-Buzzy et al, 2006;Faria et al, 2017). Thus, ethylene may be involved directly or indirectly in inhibiting of the flowering induction in roses.…”

Rose is one of the most important cut flower in the world. Rose micropropagation was used for production of clonal and disease-free plantlets and to breeding purposes. However, many important rose cultivars showed physiological disorders as early-leaf senescence and very low multiplication rate under in vitro conditions. Our hypothesis is that these symptoms were associated with high sensibility of these cultivars to ethylene accumulation on in vitro environment. The rose cv. Sena was in vitro cultivated under different concentrations of AgNO3 and two light sources, LED and fluorescent lamps, as a way to investigate in vitro similar symptoms to ethylene accumulation. AgNO3 at 1.0-2.0 mg L-1 solved the main in vitro physiological disorders observed in this rose cultivar. Also, AgNO3 stimulated induction of 50% of rose shoots to in vitro flowering at 2.0 mg L-1. Higher concentrations also resulted in flowering induction, but with imperfect flower development.
