RESUMO
Tomato is an important crop due to its nutritional contributions and organoleptic properties, which make it an appetizing vegetable around the world. In its sowing, the use of seed is the most accessible propagation mechanism for farmers. However, the induction to germination and emergence is often limited in the absence of stimulants that promote the development and growth of the seedling, added to the interference of infectious agents that notoriously reduce the vitality and viability of the seed. Given this, it was proposed as a research objective to determine the effect of zinc oxide nanoparticles (ZnO NPs) mediated by a green route on the germinative characteristics of Lycopersicon esculentum Mill. 1768 "tomato". The experimental phase consisted of the synthesis of ZnO NPs and its subsequent characterization. After its synthesis, its inoculation was conducted during the germination of seeds of L. esculentum, considering six sample groups for the treatment with zinc nanoparticles (T1: Control; T2: 21.31 ppm; T3: 33.58 ppm; T4: 49.15 ppm; T5: 63.59 and T6: 99.076 ppm). The results indicate that concentrations close to 100 ppm of ZnO NPs are ideal in the treatment of L. esculentum seeds, due to the promotion of enzymatic and metabolic activity to achieve cell elongation; likewise, the biosynthesized nanoparticles showed no phytotoxicity, due to the fact that, in all the treatments, there were processes of germination and emergence. This was linked to the generation of a Zn0-phenolate complex through a chelating effect, which generates compatibility with the seed and, compared to classic inorganic synthesis, usually shows phytotoxicity. In this sense, green synthesis is presented as a great alternative in this type of application.

Se sabe que las comunidades Andino-Amazónicas a través de la historia han hecho un correcto y eficaz uso de sus recursos florísticos, que al domesticarlas inteligentemente se han constituido en verdaderos aportes del Perú para la humanidad. Por ello esta investigación se avocó a determinar los aspectos etnobotánicos de las especies empleadas por la Comunidad Campesina de Cuspón. Se aplicaron 150 entrevistas semi-estructuradas, para recabar información referente a: taxonomía, nombres vulgares, hábito o porte, hábitat, forma de propagación, parte utilizada y uso etnobotánico, para luego determinar el Índice Cultural (IC). La comunidad de Cuspón utiliza en sus más diversas necesidades 57 especies de plantas distribuidas en 48 géneros y 30 familias; siendo las más representativas las Asteraceaes (11), solanaceae (4), Euphorbiaceae (3), Malvaceae (3), Onagraceae (3) y Urticaceae (3); y las especies más importantes: Solanum tuberosum L. "papa" (IC = 1,33), Zea mays L. "maíz" (IC = 1,31), Chenopodium quinoa Willd. "quinua" (IC = 1,06), Caesalpinia spinosa (Molina) Kuntze "talla" (IC = 0,97), Capsicum pubescens Ruiz & Pav. "rocoto" (IC = 0,95), Juglans neotropica Diels "nogal" (IC = 0,92), Alnus acuminata Kunth "aliso" (IC = 0,86), Cestrum auriculatum L'Hér. "hierba santa", Minthostachys mollis (Benth.) Griseb. "muña" (IC = 0,85).

La presente investigación se avocó a determinar el valor de uso etnomedicinal dado a la flora del Cerro "La Botica", por la Comunidad Andina de Cachicadán, Santiago de Chuco, Perú. Se aplicaron 96 entrevistas semiestructuradas, siguiendo la técnica "bola de nieve". Se realizaron colectas mediante exploraciones botánicas. Para cada una de las especies se detallaron los datos de familia, nombre científico y común, parte utilizada, enfermedad o dolencia tratada, ubicación en UTM e índice de valor de uso (IVU). Se reportan 48 especies empleadas etnomedicinalmente por la Comunidad Andina de Cachicadán, distribuidas en 46 géneros y 26 familias, de las que destacan por su número de especies: Asteraceae (10), Rosaceae (5) y Lamiaceae (3). De estas, el 72 % (35 especies) resultan muy importantes para la cura o tratamiento de sus enfermedades, según su valor de uso (IVU). Además los pobladores de la Comunidad Andina de Cachicadán, refieren padecer de 38 enfermedades o dolencias; agrupadas en 10 categorías, donde prevalecen, las de los sistemas: respiratorio (FCI=0.88), digestivo y gastrointestinal (FCI=0.85), reproductivo (FCI=0.84), urinario (FCI= 0.84), nervioso (FCI=0.83), Músculo-esquelético (FCI=0.82), cardiovascular (FCI=0.82) y rituales (FCI=0.81).
The present investigation was aimed at determining the value of ethnomedicinal use that is given to the flora of the Hill "La Botica", by the Andean Community of Cachicadán, Santiago de Chuco, Perú. 96 semi-structured interviews were applied, following the "snowball" technique. Collections were made by botanical explorations.For each of the species, family data, scientific and common name, part used, disease or disease treated, location in UTM and use value index (IVU) were detailed. 48 species of flora are used ethnobotanically by the Andean Community of Cachicadán, distributed in 46 genera and 26 families, of which they stand out for their number of species: Asteraceae (10), Rosaceae (5) and Lamiaceae (3). Of these, 72% (35 species) are very important for the cure or treatment of their diseases, according to their use value (IVU). In addition the inhabitants of the Andean Community of Cachicadán, report suffering from 38 diseases or ailments; grouped into 10 categories, where they prevail, those of the systems: respiratory (FCI = 0.88), digestive and gastrointestinal (FCI = 0.85), reproductive (FCI = 0.84), urinary (FCI = 0.84), nervous (FCI = 0.83), Musculoskeletal (FCI = 0.82), cardiovascular (FCI = 0.82) and rituals (FCI = 0.81).

Peru is not only megadiverse in flora and fauna, but also in "native varieties of potatoes" that have been used by pre-Inca civilizations. In this context, "native potatoes" not only have a high nutritional value in antioxidants, but also a high capacity to cure and/or alleviate diseases; providing quality of life that is reflected in the longevity of the Andean population. However, in the absence of documentation and dissemination, many varieties and their ethnobotanical knowledge is being lost. To preserve and disseminate this valuable ancestral knowledge, a taxonomic, phytogeographic and ethnobotanical inventory was carried out, based on periodic botanical explorations during the period 1997-2017. The information obtained was complemented with other researches and reports by other authors. 317 "varieties of native potato" are reported for the North of Peru, of which 86, are "native varieties of colored pulp".
