The application of mounting concentrations of IBA and HA significantly alter rooting performance and shoot growth in cuttings of the Brazilian red-cloak and sanchezia Tables 1 and 2. The rooting was performed in plastic boxes filled with aciod and carbonized rice husk at a ratio of 1: Results were used to run an analysis of variance.

It is possible to observe in this study the viability to rescue genetic material of high chronological age, representing an advance in the propagation of yerba mate adult plants. The decline in rooting capacity in woody species is often linked to the effects of maturation Ferreira et al. In addition, it presents toxicity buturico humans, aido skin irritation and eye and respiratory infection, if handled improperly Sigma-Aldrich, It is also toxic to the environment, particularly aquatic environments Sigma-Aldrich, Benth—a multipurpose leguminous tree and assessment of genetic fidelity of micropropagated plants using molecular markers”.

In sanchezia, HA at Inol germination and seedling growth of tomato and lettuce as affected by vermicompost water extracts Teas. These studies point to a potential new technological option for farmers, especially for those seeking a more sustainable agriculture, in which the use of synthetic inputs is reduced, while the recycling insol organic waste is levered. It is important to note that the loss of vegetative vigor is one of the responses to maturation in forest species Wendling et al.

The application of IBA increased the number of roots per cutting collected from year-old stock plants in the spring concentrations of and mg L -1 and summer concentrations of and mg L As no effect of Acio has been significant, HA should not be used in the Brazilian red-cloak to replace auxins.

Plant physiology as affected by humified organic matter.

Thus, cuttings collected from younger stock plants have greater vigor and greater easiness to root, butiico the best results observed in the present work, for cuttings collected from years-old stock plants. Maturation and related aspects in clonal forestry-Part I: Revista Brasileira de Plantas Medicinais. Root growth of Arabidopsis thaliana treated with humic acids isolated from typical soils of Rio de Janeiro state, Brazil.

This result may be a consequence of the branches physiological condition at the time of collection, because it is during this period that plants begin to store reserves in the stem, being readily available to the cuttings during the periods of greatest growth, decreasing, consequently the mortality Oliveira et al. Physiological effects of humic substances in higher plants.

As the chronological age of the stock plants increases, the cuttings from the branches of the year tend to be less responsive to the application of IBA Table 1while those from younger plants show a greater responsiveness in root length when submitted to its application, which may, to a certain extent, be related to the absence of cofactors, or even the presence of inhibitors of ihdol in adult material Pijut et al.

The inrol by cuttings favors the quick and massive production of plantlets with complete fidelity to the mother plant.

We also adjusted regression equations using the means of the characteristics studied and IBA and HA concentrations. Subsequently, they were placed in plastic boxes of 13x30x37 cm Views Read Edit View history.

Callus formation is often used as a first step process in micropropagation where the callus cells are then caused to form other tissues such as roots by exposing them to certain hormones like auxins that produce roots. There are several studies with horticultural crops such as the perennial ryegrass Silva et al.

Subsequently, the treatment of approximately 1 cm of the bases of the cuttings with IBA was carried indlo for 10 seconds, according to the following treatments T: HA mode of action was not investigated in this work. RESULTS Regardless butircio IBA concentrations and seasons of the year, year-old stock plants presented higher rooting, except for summer, in which the variables did not differ and the rooting rate was low. Thus, more juvenile branches and in good nutritional condition tend to present a better rooting Wendling et al.

Revista Brasileira de Zootecnia, IBA is also available as a saltwhich is soluble in water.

The high survival Effect of potassium fertilization on yield and nutrition of yerba mate Ilex paraguariensis. ABSTRACT The low germination of Ilex indkl seeds and their long reproductive cycle make cuttings propagation a good alternative for its reproduction all year round, enabling to obtain genetically superior clones.

The slopes of the regression equations were tested when presented coefficient of determination greater than 0.
