Passiflora suberosa L. (Passifloraceae) can be found throughout the Americas, and has several medicinal properties, including antioxidant, antibacterial, anti-hemolytic, hypolipidemic, and hypoglycemic activities. Germination rates of P. suberosa are low, even with dormancy breaking treatments, posing an obstacle for its multiplication. Vegetative propagation is a valuable approach to produce clones of elite individuals with important pharmacological characteristics, affording fast genetic improvement of biomass source for both phytomedicine manufacturing and bioactive compound isolation. Understanding the rooting process of this species is an important step to exploit its full potential in a sustainable way. We investigated adventitious rooting (AR) in absence or presence of exogenous auxin in P. suberosa cuttings, using a non-aerated hydroponic system. Changes in concentration of flavonoids, phenolics, hexoses, starch, and auxin, as well as peroxidase activity, were monitored along AR. Cuttings showed spontaneous rooting, although the application of exogenous indole-3-butyric acid (IBA) yielded higher number of shorter roots. Biochemical parameters, mainly concentration of carbohydrates and total phenolics, as well as peroxidase activity, varied along the course of the experiments. Based on these results, attempts were made to up- or down-modulate rooting responses by applying putative regulators to the growth solution at different time points. It was possible to block the positive effect of auxin on root development, with only minor positive impacts on the modulated control devoid of auxin. Overall analyses suggested that the rooting system proved effective and specific peroxidase activity showed partial correlation with AR, being able to suffer modulation by culture solution factors.

Cavendishia bracteata and Thibaudia floribunda (Ericaceae) are wild fruit shrubs native to the Andes region. This study aimed to characterize the rooting potential of basal and apical cuttings using naphthalene acetic acid (NAA) in different concentrations (0, 200, 500, or 1,000 mg L-1). In C. bracteata, the cutting position on the branch affected its sprouting and rooting, with apical cuttings presenting the best performance with auxin application. The rooting of cuttings was more successful in C. bracteata than in T. floribunda. NAA applications between 200 to 500 mg L-1 were more suitable for the propagation of C. bracteata due to the higher percentages of rooting and shoot production. For propagation of T. floribunda, the use of apical cuttings without the application of auxins is recommended. Adventitious roots in cuttings of both species were originated from parenchyma cells of the stem.

Native Piper species present significant repellent, antimicrobial, inseticidal, anti-tumor and anti-protozoal biological activities. Studies on new species can discover unpublished potentialities and vegetative propagation for the development of cultivation protocols and reduce the natural extraction. The objective of this study was to evaluate the rooting of P. arboreum, P. cernuum and P. diospyrifolium stem cuttings with different treatments containing doses of indole butyric acid (0, 500; 1,000; 1,500; 2,000 and 3,000 mg L-1). Branches were collected in the “Bom Jesus Biological Reserve”, Parana state, Brazil. The cuttings, with a length of 12 cm and average diameter of 6 mm, were placed in 53 cm3 plastic tubes with the commercial substrate Tropstrato HP® and intermittent misting. After 90 days, the survival, mortality, cuttings with new shoots, number and length of the three main roots were evaluated. The percentages of rooting reached an average of 67.5% for P. arboreum, 51.6% for P. cernuum and 50.4% for P. diospyrifolium. A positive effect in the treatments containing the plant regulator was observed for rooting development, percentage of cuttings with shoots and number of roots per propagule, but there were variations in the responses of each species. Leaf retention was an important factor for the adventitious rooting formation in all evaluated species.

Positive Effect

 Donkeys (Equus asinus) face a global crisis. The health, welfare, and even survival of donkeys are being compromised as the demand for their skins increases. It is driven by the production of ejiao, a traditional Chinese remedy believed by some to have medicinal properties. It is estimated that the ejiao industry currently requires approximately 4.8 million donkey skins per year. Since there is no productive chain for donkey skin production outside of China, the activity is extractive and has resulted in the decimation of donkeys. Gestation is 12 months in donkeys, increasing the risk of extinction if such practices are not controlled. In this scenario, the donkeys are collected (purchased for low prices, stolen, and collected from the side of the roads) and are then often transported for long distances, usually without water, food, or rest. The trade, in Brazil, poses significant biosecurity risks, particularly because examinations are rarely conducted and therefore infectious diseases, such as glanders and infectious anemia, remain undetected. Furthermore, in chronic stress situations, the immune system is suppressed, increasing the biosecurity risk, especially because donkeys are a silent carrier of diseases. Rarely there is traceability with animals from different origins being put together in “fake farms”, before being delivered to slaughterhouses. The opportunistic strategy of collecting animals, or buying for low prices, keeping them without access to food and veterinary assistance, is what makes this trade profitable. Our experience in donkey welfare and the global skin trade suggest that it will be enormously challenging and cost-prohibitive to run a trade at the standards required to be considered humane, sustainable, and safe. Although donkeys are being blamed for the involvement in road accidents, it is not an ethical solution to maintain this trade as an alternative. Moreover, the ecological role of donkeys in native ecosystems has not been elucidated, and some studies indicate they could even have a positive effect. Regardless of the future the donkeys will have; we must guarantee a life with the least dignity to the animals under our responsibility.

The soil in the production of clonal seedlings of black pepper (Piper nigrum L.) contributes to fusarium and nematodes infestation in commercial crops, and thus the usage of alternative substrates might be a preventive control measure against these pathogens. The aim of this study was to investigate the rhizogenic behavior of the cultivars Bragantina, Iaçará and Guajarina of black pepper in different substrates. The experimental design was in randomized blocks in a 3x4 factorial design (cultivars: Bragantina, Iaçará and Guajarina x substrates: soil + organic compound (18%), vermiculite, carbonized rice hulls and commercial substrate), with four replications of 16 cuttings each. The evaluated characteristics were: survival (%); rooting (basal or nodal) (%); nodal rooting (%); basal rooting (%); number of nodal roots; number of basal roots; total number of roots; length of the largest nodal root (cm); basal root length (cm); nodal root volume (cm3); basal root volume (cm3); Total root volume (cm3); nodal root dry mass (mg); basal root dry mass (mg) and the total root dry mass (mg). There are differences within black pepper cultivars as to the characteristics related to the root system. The vermiculite substrate was the most suitable, and carbonized rice hull is not recommended for the adventitious rooting of cuttings of cultivars Bragantina, Iaçará and Guajarina.

ABSTRACT The competence of adult plants of mate (Ilex paraguariensis St. Hil.) to undergo adventitious rooting is essential to their vegetative rescue by cuttings. This study aimed to evaluate the adventitious rooting competence of adult mate plants, and then rescue these plants by making cuttings from epicormic shoots induced in different trunk positions. The percent survival and rooting of cuttings from epicormic shoots induced by girdling in seven adult plants were evaluated. The two stock plants whose cuttings had the highest rooting competence were further pruned and girdled to evaluate the effect of the position of epicormic shoots on their adventitious rooting competence. The potential success of rescuing of the same adult plants was also studied with cuttings of epicormic shoots induced by coppicing. The shoots were sectioned in single-bud cuttings, either treated with 3,000 mg L-1 indolebutyric acid or untreated, and then cultivated in a humid chamber for 60 days, and then the percent survival and rooting of cuttings was evaluated. In conclusion, we found that it is possible to rescue adult mate plants by cuttings from epicormic shoots induced by pruning, girdling, or coppicing. The adventitious rooting competence of cuttings differs among adult mate plants, and depends on the position of the epicormic shoots on the trunk from which epicormic shoots are collected.

Peroxidases seem to play an important role in the regulation of auxin levels during the rooting of cuttings. In avocado, leaf peroxidase activity remained constant throughout the rooting process in the three fractions analyzed (soluble, ionically, and covalently bound to cell wall). Soluble peroxidase activity in stem basal parts increased twofold after 3 days and then remained constant until the end of the process. Cationic and anionic electrophoresis revealed a lower number of isoenzymes in the stems than in the leaves. Histological stainings at stem basal parts were also carried out to localize the enzyme activity. Peroxidase was active in all tissues at the time the cutting was taken, with vascular bundles and epidermis giving the strongest reactions. During the process of root formation peroxidase activity was closely associated with growth and differentiation processes, e.g., cambial cell division and xylogenesis; a strong reaction was also found in the developing root primordia. The possible role of peroxidases in the regulation of auxin levels during the rooting process in avocado is discussed. Key words: auxin, avocado, peroxidase, rooting.
