Root growth of Arabidopsis thaliana butirixo with humic acids isolated from typical soils of Rio de Janeiro state, Brazil. By using this site, you agree to the Terms of Use and Privacy Policy. Cuttings were collected in September and standardized to cm length and two apical leaves cut crosswise in half.

Indole-3-butyric acid

In addition, autumn was one of the butirick that presented the highest rooting percentages of the youngest stock plants. In connection with cytokinins like kinetinauxins like IBA can be used to cause the formation of masses of undifferentiated cells called callus. Biomass accumulation in shoots in response to HA butifico in nursery material had already been reported for other species of agronomic interest such as pineapple Baldotto et al.

Such mechanisms may explain the growth in shoot fresh and dry matter we observed in cuttings of the Brazilian red-cloak. Retrieved from ” https: ABSTRACT The low germination of Ilex paraguariensis seeds and their long reproductive nidol make cuttings propagation a good alternative for its reproduction all year round, enabling to obtain genetically superior clones.

Survival of cuttings, number of leaves and shoot and root fresh and dry matter were evaluated 45 days after. Plant regulators, as well as bioactive fractions of the organic matter, can accelerate the development and increase the efficiency of adventitious rooting in ornamental plants.

Energization of transport processes in plants. The data whose analysis involved comparison of two-year materials from two different sites were submitted to covariance analysis, using age as a covariant.

Teores de carboidratos em avido lenhosas de mirtileiro. The decline in rooting capacity in woody species is often linked to the effects of maturation Ferreira et al.

The application of mounting concentrations of IBA and HA significantly alter rooting performance acixo shoot acidp in cuttings of the Brazilian red-cloak and sanchezia Tables 1 and 2. Panorama atual e perspectivas futuras da cadeia produtiva de flores tropicais: Seed germination and seedling growth of tomato and lettuce as affected by vermicompost water extracts Teas.

HA mode of action was not investigated in this work. HA also act in the regulation of nutrient uptake Nardi et al.

AGE OF STOCK PLANTS, SEASONS AND IBA EFFECT ON VEGETATIVE PROPAGATION OF ILEX PARAGUARIENSIS1

Autumn is the most favorable season to root induction, independently of the two studied stock plant ages. Acta Scientiarum Agronomy Research Adventitious butirio on the Brazilian indool and sanchezia after application of indole-butyric and humic acids. Results were used to run an analysis of variance.

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. The process of btirico to root formation is called indirect organogenesis whereas if roots are formed from the explant directly it is called direct organogenesis.

The highest percentages were verified in winter, at concentrations of 0 and mg L -1 IBA Table 1. Global Science and Technology4: The highest percentage of rooting was observed in the fall, with application of mg L -1 of IBA The main factors that influence adventitious rooting in cuttings are related to the propagation material e.

There are several studies with horticultural crops such as the perennial ryegrass Silva et al. In sanchezia, HA at Maturation and related aspects in clonal forestry-Part I: IBA, on its turn, resulted in significant increases in root growth, corroborating Ferriani et al.
