“…A wide variety of biological activities is assigned for these compounds, such as antimicrobial, antiviral, anti-inflammatory, antispasmodic, antitumoral, anticoagulant, bronchodilator and antioxidant (Pereira et al, 1992;Hoult & Payá, 1996). The coumarin (1,2-benzopyran) (1), dihydrocoumarin and o-coumaric acid were identified in extracts of M. glomerata (Vidal et al, 2006) and M. laevigata (Oliveira et al, 1984). discovered in M. congesta aerial parts, growing in the state of Pará-Brazil, some similar compounds such as scopoletin (2), O-geranylscopoletin.…”

Abstract:The genus Mikania ranks high in the list of best-selling natural products in the world. Its main distribution is in South America, but some species are found in Asia, North America and Africa. It is used for treating fever, rheumatism, colds and respiratory diseases, as well as snake bites and scorpion stings, due to its broad spectrum of action. There are approximately 430 species of this genus and only 12% have been studied, highlighting their chemical and pharmacological diversity. The main chemical groups are: coumarins and derivatives, sesquiterpenes, sesquiterpenes lactones, diterpenes, phytosterols/terpenoids and flavonoids. This review aims to supply useful references for scientists interested in natural products and the search for new compounds, from over the 300 already described for the genus.

“…(Tabela 1). Na espécie Mikania glomerata Spreng., nota-se a formação de raízes independente da adição de matéria orgânica (vermicomposto) (Vidal et al, 2006). Verifica-se a necessidade de fazer a mistura de componentes e selecionar a melhor combinação para encontrar o substrato que atenda as características físicas e nutricionais exigidas pelas mudas (Paulus et al 2011).…”

RESUMO:O presente trabalho teve como objetivo avaliar a propagação vegetativa do assapeixe Vernonia polyanthes Less utilizando estacas apicais e diferentes substratos. O experimento foi conduzido em condições de casa de vegetação com irrigação controlada na Faculdade de Ciências Agronômicas da UNESP campus Botucatu-SP. O delineamento experimental utilizado foi o inteiramente casualizado, com sete tratamentos (Solo de textura argilosa; 50% Solo de textura argilosa + 50% Húmus; Solo de textura média; 50% Solo de textura média + 50% Húmus; Solo de textura arenosa; 50% Solo de textura arenosa + 50% Húmus; Húmus) e quatro repetições, sendo 10 estacas por repetição. As características avaliadas foram: comprimento da maior raiz, comprimento da parte aérea, número de brotações, porcentagem de enraizamento, volume radicular, nota para qualidade das estacas e massa seca da parte aérea e das raízes. Os dados foram submetidos à análise de variância pelo teste F e as médias comparadas pelo teste de Scott & Knott a 5% de probabilidade. Para a análise estatística, utilizou-se o programa SISVAR ®. A partir da análise, observou-se efeito altamente significativo dos tratamentos utilizados para todas as variáveis analisadas, com exceção da massa seca da parte aérea, que não apresentou diferença significativa. Para obtenção de melhor enraizamento da espécie em questão, o recomendado é a utilização do substrato: solo de textura argilosa ou média, acrescido de húmus na proporção de 1:1.

The current study aimed to evaluate the vegetative propagation of assa-peixe using apical cuttings and different substrates. The trial was conducted under greenhouse conditions with controlled irrigation, in the Faculdade de Ciências Agronômicas of UNESP in Botucatu-SP campus. The experimental design was completely randomized, with seven treatments and four replications, with 10 cuttings per replicate. The characteristics were: longest root length, shoot length, number of shoots, rooting percentage, root volume, score of quality of cuttings and dry mass of shoots and roots. The data were subjected to analysis of variance by F test and the averages were compared by the Scott Knott test at 5% probability. For statistical analysis, we used the SISVAR ®. From the analysis, we observed highly relevant effect of the treatments used for all variables, with the exception of the dry weight of shoots, which did not present significant difference. In order to obtain a better rooting of the species concerned, the recommended method would be to use substrates such as clayey soil or medium plus humus in the ratio 1:1.

“…Plant height was also not influenced by the different substrates, either for S1 (40% commercial substrate) or S3 (60% commercial substrate), and the development of the seedlings related to the height was very similar. According to Vidal et al [11] , the Mikania glomerata cuttings developed on substrates with different concentrations of vermiculite did not show significant differences among the parameters evaluated, indicating that for some species the variation in the substrate does not influence the development of the plant.…”

Biodegradable bags for the production of plant seedlings

et al. 2014

Abstract:The production of plant seedlings has traditionally used polyethylene bags, which are thrown out in the soil or burned after transplant because the large amount of organic material attached to the bags makes recycling difficult. Additionally, when a seedling is taken from the bag for transplant, there is the risk of root damage, which compromises the plant's development. In this study, we developed biodegradable bags to be used in seedling production, and we verify their influence on the development of Brazilian ginseng (Pfaffia glomerata (Spreng) Pedersen), when the plant is planted without being removed from the bag. Both black and white biodegradable bags remained intact throughout the seedling production period (60 days). After being transplanted into containers (240 days), they were completely biodegraded, and there was no significant difference between the dry mass of these plants and that of plants that were transplanted without the bags. The plants that were cultivated without being removed from the polyethylene bags had root development difficulties, and the wrapping showed no signs of degradation. The use of biodegradable films is an alternative for the production of bags for seedlings, as these can then be transplanted directly into the soil without removing the bag, reducing the risk of damage to the roots during the moment of transplant.
