The experiments were carried out in a completely randomized design, with 2x5x4 factorial arrangement 2 ages of stock plants, 5 IBA concentrations and 4 seasons of the yearwith 4 replications of 20 cuttings per experimental unit.

Other names 1 H -indolebutanoic acid indolebutyric acid 3-indolebutyric acid indolebutyric acid IBA. It presents acute toxicity when ingested and cause irritation of skin, eyes and the respiratory tract if inhaled Sigma-Aldrich, 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.

Aquifoliaceaealso known as yerba mate, is a tree species that can reach 20 meters in height. ABSTRACT Plant regulators, as well as bioactive fractions of the organic matter, can accelerate the development and increase indo, efficiency of adventitious rooting in ornamental plants.

Indole-3-butyric acid

Vegetative propagation of mature dragon trees through epicormic shoots. The solution should be kept in a cool, dark place for best results. Plantas ornamentais no Brasil: The high mortality seems to be related mainly to the harvesting season, since in the autumn the mortality was low for the two plants ages, as well as for all the concentrations of IBA used. Ilex paraguariensis; Resgate vegetativo; Silvicultura clonal.

Aido of auxin treatments, cuttings collection date and initial characteristics on Paeonia ‘Yang Fei Chu Yu’ cutting propagation. We concluded that IBA, in the abovementioned concentrations, increased adventitious rooting in cuttings of both the Brazilian red-cloak and sanchezia, while optimal doses of HA solutions are very likely to improve adventitious rooting in sanchezia, but not in the Brazilian red-cloak.

HA alter growth and development of various plants of agronomic interest, accelerating root growth and boosting plant biomass Zandonadi et al.

Ácido indol-3-acético

Physiol Mol Biol Plants. Gladiolus development in response to bulb treatment with different concentrations of humic acids. Carboxylic acids Indoles Auxins. Cuttings from years-old stock plants have higher ability to form adventitious roots and the use of IBA did not increase rooting potential.

In this study we established the concentrations of indole-butyric acid IBA and humic acids HA that promoted growth and adventitious rooting of cuttings of the Brazilian red-cloak and sanchezia, aiming at speeding up and improving the efficiency of vegetative propagation in these species. However, plant ondol to HA application is not uniform and varies with the raw material which these compounds where extracted from and butirick concentration, and plant genotype Baldotto et al.

Acta Scientiarum Agronomy Summer showed the highest percentage of live cuttings, regardless of IBA concentrations, reaching The slopes of the regression equations were tested when presented coefficient of determination greater than 0. Promotion of adventitious root formation of difficult-to-root hardwood tree species. This page was last edited on 29 Octoberat HA also act in the regulation of nutrient uptake Nardi et al.

This compound had been thought to be strictly synthetic ; however, it was reported that the compound was isolated from leaves and seeds of maize and other species. Panorama atual e perspectivas futuras da cadeia produtiva de flores tropicais: It is possible to observe in this study the viability to rescue genetic material of high chronological age, representing adido advance in the propagation of yerba mate adult plants.

In addition, acldo metabolic and physiological activities in plants have their regulation, among other factors, through the temperature variation in the environment Floss,and can act acdo on the adventitious root emission Brondani et al. Maturation and related aspects in clonal forestry-Part I: International Journal of Botany. In plant tissue culture IBA and other auxins are used to initiate root formation in vitro in a procedure called micropropagation.

It occurs insol in South America Carvalho, where it has great economic importance, since its leaves are used in medicine and consumed in the form of tea Dartora et al. Autumn proved to be the most favorable season for rooting, followed by spring and winter.

This alcohol solution is then diluted with distilled water to the desired concentration. Yerba mate; Vegetative rescue; Clonal forestry. There are several studies with horticultural crops such as the perennial ryegrass Silva 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
