“…Ming (1994) tested organic fertilizer treatments in L. alba and managed to increase plant biomass but, at the same time, there was a decrease in essential oil contents. Stefanini et al (2002) did not report differences in leaf production when different combinations of plant regulators were used, but variations were significant in relation to harvest season. For other species, leaf dry matter changed with the use of hormones, as in Cymbopogon spp.…”

Lippia alba (Verbenaceae) is a shrub whose essential oil has important biological, pharmacological, and aromatizing properties. To reach the sustained cultivation of new species with economic potential, the present study aimed to evaluate L. alba performance for fresh leaf matter (FM), leaf dry matter (DM), virus symptoms (VS -Cucumber mosaic virus, CMV), oil yield (OY), and oil chemical composition (OC), and to evaluate DM stability and adaptability. Ten genotypes of four chemical groups (chemotypes) were evaluated in six experiments designed as randomized blocks with two plants per plot, over the whole State of São Paulo, Brazil. A 2.0 × 0.4 × 1.6 m spacing was used in Monte Alegre do Sul and Pindorama, while a 1.0 × 0.4 × 0.6 m spacing was used in Campinas, where four experiments were established under different irrigation and fertilization conditions. The genotype effect was significant (p < 0.05) for all traits evaluated, with high leaf productivity of IAC-16 (citral chemotype), best OY means in the linalool and limonene/carvone chemotypes, and susceptibility of the latter chemotype to CMV. The genotype performance oscillations in the six environments were significant for FM and DM, and despite their significance for phytochemical traits (OY and OC), they were of low magnitude. No qualitative variation was detected for OC. The IAC-2 (linalool) and IAC-13 (limonene/carvone) genotypes showed high stability and wide adaptability, and are recommended to establish initial cultivations of this species. This research also indicated genetic sources to start Lippia alba genetic breeding programs. IAC-1 to IAC-4 (linalool), IAC-9 to IAC-11 (myrcene/ camphor), IAC-13 and IAC-14 (limonene/carvone), and IAC-16 (citral). Plants were selected based on differences in plant morphology, oil yield, and the relative proportions of substances in the oil. Six experiments were carried out in three regions of the State of São Paulo (SP), Brazil, in a randomized block design, with four replicates and two plants (clones) per plot. Four experiments were installed in Campinas (22°31' S, 47°02' W, 680 m), representing four environments (E1 -with both fertilization and irrigation; E2 -with fertilization but no irrigation; E3 -no fertilization but with irrigation; E4 -no fertilization nor irrigation). As to fertilization, two sidedressing applications of the 04-14-08 (N, P 2 O 5 , K 2 O) fertilizer were made, and a drip irrigation system was used. A row spacing of 1.0 m was adopted in these four experiments (environments), with 0.4 m between clones and 0.6 m between plots. The other two experiments were carried out in Monte Alegre do Sul (22°24' S, 46°24' W, 760 m) (E5) and Pindorama (21°06' S, 48°32' W, 534 m) (E6), with a row spacing of 2 m, 0.4 m between clones, and 1.6 m between plots, under a sprinkler irrigation system.

ABSTRACT:The purpose of this work is to know more about medicinal plants, forms of usage and therapeutic indications determined by the communities of Pau-Arrastado, Salinas and Resolvido. We used semi-structured interviews, guided tours and followed the usual botanical methodology. The study sample included 93 individuals (51.9% of the total). Species were grouped into 18 categories of disease, according to the World Health Organization (WHO). We calculated the Factor of Informant Consensus (FIC) and the Index of Relative Importance (IRI). They included eighty-one (81) species, belonging to 40 botanical families and 69 genera were referred, of which 75.3% were native ones. The most prominent family was Fabaceae (18.5%), and the leaves were the most used parts (32%). The preparation method most used was dye (38.2%). The highlights were the body systems: agents of bacterial and viral infections (27.2%), digestive system diseases (22.4%) and genitourinary diseases (19.5%). Croton campestris A. St. Hil. and Ximenia americana L. were the most versatile with an IRI of 2.00. There was a greater consensus for the plants indicated for the treatment of liver diseases.

ResumoO uso de bioestimulantes na cultura da cana-de-açúcar (Saccharum officinarum L.) é uma prática de manejo que potencialmente pode incrementar sua produtividade e o seu rendimento industrial, favorecendo o bom desempenho dos processos vitais da planta, permitindo obter melhores e maiores colheitas, mesmo sob condições ambientais adversas. Para o efeito desejado com o uso de bioestimulantes específicos é importante conhecer o processo regulado pelo hormônio ou grupo de hormônios, a dose necessária para manipular o processo, bem como o órgão da planta onde ocorrerão as reações biológicas. Por sua composição de múltiplos hormônios em baixas concentrações, bem como pelas pequenas doses recomendadas, a aplicação isolada de um bioestimulante dificilmente poderá regular ou manipular
