“…Mini Prill, respectively (Figure 1). The number of sprouts within the genus Piper is variable according to the species: for P. arboreum it is 2.23 sprouts, whereas, for P. amplum and Piper sp., it does not reach 0.27 sprouts (Magevski et al, 2011). In addition, this variation between species may occur due to the nutritional and hormonal status of the plant that donated the stake, the genotype, the planting season and climatic conditions, and cultural management, and variation may even occur within the species itself.…”

Commercial substrates and their fertilization are essential for the morphophysiological, nutritional, and sanitary quality of seedlings. In this perspective, this study aimed to evaluate the quality of clonal seedlings of the black pepper cultivar Bragantina under doses of controlled-release fertilizers (CLF) in a commercial substrate. The treatments were constituted by five doses of the CLF Osmocote® 19-06-10 Mini Prill (3-4 months) (0, 2, 4, 6, and 8 kg m-3), with four replications of 16 cuttings. The CLF Osmocote®, especially in doses close to 4.16 kg m-3, showed to be promising for the production of clonal seedlings of the black pepper cultivar Bragantina.

“…1C). The fact that the maximum efficiency of sprouting was lower than that observed for rooting may be associated with the fact that the synthetic auxin mobilized nutrients for root formation, inhibiting sprouting when applied at the base of the cutting (Magevski et al, 2011), so, when the better conditions to rooting were provided, some reduction in sprouting was observed.…”

Stevia rebaudiana Bertoni es una especie de alta importancia económica debido a la producción de edulcorantes naturales con bajo valor calórico. La producción de semillas de esta especie es irregular y las técnicas de micropropagación aumentan el costo de la producción de plántulas. Por lo tanto, este trabajo tuvo como objetivo optimizar la propagación vegetativa de un genotipo brasileño de esta especie a través de estacas de tallo. El material vegetal se recogió de plantas maduras con 1 año de edad. Se realizaron dos experimentos para determinar la mejor concentración de ácido indolbutírico (IBA) para mejorar el enraizamiento y evaluar la interacción entre la posición de corte del tallo (apical, mediana y basal) y sustratos (Tropstrato HT®, vermiculita y mezcla de vermiculita y Tropstrato HT®). Las estacas de tallos se vieron afectadas por las concentraciones de IBA. Se recomienda la aplicación de 710 mg L-1 de IBA para mayores porcentajes de enraizamiento. Las estacas de tallos de la región apical de las plantas mostraron mayor porcentaje de enraizamiento que las medianas y basales (medias de 70, 45,8 y 7,5%, respectivamente). Se observaron resultados similares para el número, longitud y masa de raíz fresca y seca. El sustrato Tropstrato HT® promovió mayores porcentajes de enraizamiento de las estacas de tallo y menor mortalidad en comparación con la vermiculita.

“…Like Capsicum and Zingiber, species of this genus are also popularly used by the pharmaceutical and food industries. [67][68][69][70] Species such as Piper gaudichaudianum and Piper aduncum are known by their antitumoral, antimicrobial, antifungal, insecticidal and anti-inflammatory activities. 71 The main metabolite responsible for Piper species pungency is piperine ( Figure 5).…”

Civilian defense devices are physical and chemical artefacts used to incapacitate an aggressor without causing death or injury. As city violence increases, safety feelings became worst and a growing commercial demand for these materials supply faces technologically challenges not only to riot control but also to self-protection. Controversies on the use of these devices have been discussed, especially on their toxicity when synthetic chemical agents are used. Natural metabolites are a less explored alternative to meet this demand. They have the capacity to generate a temporary disabling effect due to their pungency. Those metabolites, which include capsaicinoids, gingerols and piperine, can be used as deterrent agents in civilian defense devices due to their low toxicity to humans. Although they are a viable alternative, there are few studies focused on their quality control, efficiency and toxicity. This review aimed to present relevant aspects about the development and use of natural products as deterrent agents in self-defense devices against aggressors and animals, and as non-lethal weapons for riot control in order to help the scientific development of this type of bioproduct. was a member of the CAPES and Brazilian pharmacopoeia committees and has published 143 articles in specialized magazines, 13 patents and 38 book chapters, with 50 thesis and dissertations supervised.
