Ilex paraguariensis St. Hil. (erva-mate), the mate tea, is a forest tree whose natural distribution in the Brazilian territory embraces the States of Mato Grosso do Sul, Paraná, Santa Catarina and Rio Grande do Sul. Its economical importance is moreover related to tea production. The purpose of this study is to characterize the leaf chemical composition in relation to different plantation and management conditions. Chemical analysis were performed on plants of different ages,in naturally occurring areas, planted stands, and seedbeds. The most remarkable elements observed in the study were P with average values ranging from 0,5 - 3,2 g kg-1 D.W., Mn values from 346 - 3.330 mg kg-1 D.W., and Al values from 167 - 1.235 mg kg-1 D.W. |

ABSTRACT: Drimys brasiliensis Miers is an Angiosperm native to the Atlantic Rainforest, commonly known as cataia. Because of dormancy of its seeds, due to embryonic immaturity, production of cataia seedlings presents challenges regarding propagation of the species. Thus, cuttings emerged as a possible technique to be applied, diminishing plants production time and ensuring uniformity of rooting. Stem cuttings from current year shoots were collected in autumn/2012, prepared with 10-12cm in length, a bevel cut on base and straight on top, keeping two leaves, one leaf or no leaves in the apical portion. After disinfestation, bases of cuttings were submitted to the following treatments with indole-3-butyric acid (IBA) in 50% hydro-alcoholic solution: 100%... |

Drymis brasiliensis Miers is a specie of the Winteraceae family, commonly known as cataia or pepper bark. This research was carried out with the aim to study the rooting of semihardwood cuttings, subjected to different concentrations of indolebutyric acid (IBA), collected in four seasons of the year (autumn, winter, spring and summer). Cuttings were prepared with 10-12cm length, keeping two halved leaves. Bases of cuttings were treated as follows: control (100% water), 0; 500; 1500; 3000; 4500 and 6000mg L-1 IBA.One hundred and twenty after the planting the following variables were assessed: rooting percentage, number of roots per cutting, length of roots per cutting, cutting callus percentage, cuttings with new shoots and number of cuttings that... |

Drimys brasiliensis conhecida como cataia, é uma espécie arbórea nativa da Mata Atlântica. Tem importância fitoquímica, fitoterapêutica, aromática e econômica, utilizada na fabricação de licores, condimentos, dentre outros. É considerada uma espécie de difícil multiplicação via sementes, apresentando dormência por imaturidade embrionária. Assim, objetivou-se estudar a propagação vegetativa por meio da indução do enraizamento de estacas herbáceas e semilenhosas submetidas a diferentes concentrações de ácido indolbutírico (IBA), coletadas em duas épocas do ano (junho/2011 e dezembro/2011). Foram utilizados os tratamentos: testemunha (100% água), 0 (50% água e 50% álcool); 1.500; 3.000 e 6.000 mg L-1IBA (em solução hidroalcoólica 50%) para o inverno e, no... |
