Adventitious rooting on the Brazilian red-cloak and sanchezia after application of indole-butyric and humic acids. The use of plant regulators, specifically IBA, has been recommended for stimulating and accelerating the process of adventitious root formation Guo et al.

Global Science and Technology4: ABSTRACT The low germination of Ilex paraguariensis seeds and their long reproductive cycle make cuttings propagation a good alternative for its reproduction all year round, enabling to obtain genetically superior clones.

Seed germination and seedling growth of tomato and lettuce as affected by vermicompost water extracts Teas. We observed the average contrasts, calculated the regression equations and estimated the concentrations that provided the best efficiency in terms of root dry matter. IBA, on its turn, resulted in significant increases in root growth, corroborating Ferriani et al. Plantas ornamentais no Brasil: Cuttings were collected in September and standardized to cm length and two apical leaves cut crosswise in half.

Our results indicate that the application of IBA and HA in apical cuttings of the Brazilian red-cloak and sanchezia, in the concentrations evaluated, accelerates plantlet production. Cuttings from younger stock plants are more responsive for adventitious roots formation, as well as result in the formation of a more vigorous root system. Research Adventitious rooting on the Brazilian red-cloak and sanchezia after application of indole-butyric and humic acids.

Indole-3-butyric acid

For the concentrations of 0 and mg L -1winter was the best collection period 9. In sanchezia, HA acodo Panorama atual e perspectivas futuras da cadeia produtiva de flores tropicais: Humic acids HAthe bioactive fraction of the organic matter after humification, also promotes adventitious rooting in cuttings of ornamental plants Baldotto et al.

It should be emphasized that the high survival observed in the younger stock plants, could reflect in a higher percentage of rooting, if exposed to a longer period of permanence in greenhouse. From 12 and over years-old trees shoots cuttings were made in four seasons, treated with IBA hydroalcoholic solution at concentrations of 0, and mg L These results support the hypothesis that callus formation is detrimental to the rooting of yerba mate cuttings, indicating that the rhizogenesis is direct, without the dependence of the butiirco formation of callus.

The slopes of the regression equations were tested when presented coefficient of determination greater than 0. IBA promoted increments in bhtirico traits in sanchezia Table 2.

Acta Scientiarum Agronomy IBA is a plant regulator with typical auxin hormonal action. In connection with cytokinins like kinetinauxins afido IBA can be used to cause the formation of masses of undifferentiated cells called callus. For stock plants older than 80 years, the concentrations of 0,and mg L -1 applied in spring presented the best results for this variable Table 1.


HA also act in the regulation of nutrient uptake Nardi et al. Results were used to run an analysis of variance. The highest percentages were verified in winter, at concentrations of 0 and mg L -1 IBA Table 1.

We also adjusted regression equations using the means of the characteristics studied and IBA and HA concentrations. Cuttings from years-old stock plants have higher ability to form adventitious roots and the use of IBA did not increase rooting potential.

In general, the rooting percentage, number and length of roots had higher values in years-old stock plants, a fact probably related to the greater vigor presented by these plants.

It presents acute toxicity when ingested and cause irritation of skin, eyes and the respiratory tract if inhaled Sigma-Aldrich, Maturation and related aspects in clonal forestry-part II: How to cite this article.


The highest percentage of rooting was observed in the fall, with application of mg L -1 inndol IBA IBA efficiency in promoting adventitious rooting in cuttings of ornamental plants have been reported to allamanda Loss et al. This alcohol solution is then diluted with distilled water to the desired concentration. The propagation by cuttings favors the quick and massive production of plantlets with complete fidelity to the mother plant.

Aquifoliaceaealso known as yerba mate, is a tree species that can reach 20 meters in height. Substratos e auxinas no enraizamento de estacas caulinares de espinheira-santa. The cuttings were disinfested with 0. IBA is also available as a saltwhich is soluble in water.

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. The high percentage of callus formation is another indicative of the high maturation of the used material Wendling et al.
