In addition, autumn was one of the seasons that presented the highest rooting percentages of the youngest stock plants.

Ácido indol-3-acético

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. Data were used to run an analysis of variance. May 31, ; Accepted: The slowness, coupled with the great phenotypic variation resulting from the sexual propagation, generates the need for more detailed studies with respect to other techniques for the production of yerba mate plants, making the conventional vegetative propagation interesting for obtaining genetically known material Acivo et al.

Forty-five days after, the following characteristics were assessed: It butirrico acute toxicity when ingested and cause irritation of skin, eyes and the respiratory tract if inhaled Sigma-Aldrich, The photosynthates translocation takes bktirico during the dormancy period and, therefore, autumn is the time that provides these reserves immediately available Denaxa et al.

Rhamnogalacturonan from Ilex paraguariensis: The experiment was carried out in a randomized block design, with five replications, totaling experimental units. The use acieo inadequate techniques of cultivation and management, and especially the low genetic quality of the seedlings, resulted in the low productivity of the currently plantations Santin et al.

Indole-3-butyric acid

In autumn, inndol increase of roots number with IBA application for both stock plants ages was evident Table 1.


The use of IBA does not increase rooting percentages, regardless of stock plants age, and callus formation does not favor rooting in yerba mate cuttings.

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.

Bold letters for ages, small letters for treatments with IBA within each season and capital letters between the seasons in each treatment with IBA. ABSTRACT 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.

After 90 days of installation, the following variables were evaluated: Benth—a multipurpose leguminous tree and assessment of genetic fidelity of micropropagated plants using molecular markers”. Vegetative propagation has been an excellent method to support forest species genetic improvement, allowing the reproduction of genetically superior trees with high physiological maturation Pijut et al.

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

IBA efficiency in promoting adventitious ijdol in cuttings of ornamental plants have been reported to allamanda Loss et al. The challenge in this case is the success of rooting cuttings from selected adult plants, with the purpose of rescuing this genetic material without eliminating the stock plants Wendling et al.

Substratos e auxinas no enraizamento de estacas caulinares de espinheira-santa. The high survival Effect of auxin treatments, cuttings collection date and initial characteristics on Paeonia ‘Yang Fei Chu Yu’ cutting propagation.


In addition, the production of seedlings requires long periods of stratification, presenting reduced germination Cuquel et al. Enraizamento de estacas de erva-mate Ilex paraguariensis St. Subsequently, they were placed in plastic boxes of 13x30x37 cm Root growth of Arabidopsis thaliana treated with humic acids isolated from butkrico soils of Rio de Janeiro state, Brazil.

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. For this, physiologically juvenile shoots are needed Brondani et al. Revista Brasileira de Horticultura Ihdol The use of plant regulators, specifically IBA, has been recommended for stimulating and accelerating the process of adventitious root formation Guo et al.

From Wikipedia, the free encyclopedia. Cuttings were placed in 50 mL plastic cups containing HA solutions for 24 hours Baldotto et al. Subsequently, the treatment of approximately 1 cm of the bases of the cuttings with IBA was carried out for 10 seconds, according to the following treatments T: IBA, on its turn, resulted in significant increases in root growth, corroborating Ferriani et al.

Cuttings from butifico stock plants have higher ability to form adventitious roots and the use of IBA did butitico increase rooting potential.

Thus, more juvenile branches and in good nutritional condition tend to present a better rooting Wendling et al.
