“…Since it is a native species, this results are promissing and demonstrate the eficiency of the technique of mini-cutting to the species, demonstrated by the inferior percentage of rooting obtained on researchs with convencional cuttings from adult trees of the D. brasiliensis, on which Machado et al (2011), evaluating the different effects of plant regulators on rooting of stem cuttings of the species, obtained a higher percentage of rooting (52.53%) when the auxin was used with the caffeic acid conveyed on talcum. To Zem et al (2016), the use of the IBA plant regulator (indole butyric acid) had no nfluence of the rooting of the stem cuttings of the D. brasiliensis, even so the better percentage of rooting were only 51.1%. Radomski et al (2013) also observed that the application of the IBA plant regulator had no influence on the rooting of the stem cuttings of the, having the higher percentages of rooting obtained on the study of 46.75%.…”

“…Thus, studies related to the plant spread by cutting of D. brasiliensis were accomplished in order to obtain a larger production of seedlings, cultivation uniformity and low cost of manufacture. Although, the percentage are still low, approximately 50%, obstructing the manufacture in comercial scale (MACHADO et al, 2011;ZEM et al, 2015;ZEM et al, 2016).…”

Drimys brasiliensis, popularly known as cataia or casca-d'anta, is a tree species native to the Atlantic Forest and belonging to the family Winteraceae. Due to its seeds have dormancy due to embryonic immaturity, the present work aimed to evaluate the viability of the mini-cutting technique in D. brasiliensis in different seasons of collection of the propagules. Mini-cuttings from seedlings sprouts previously produced by conventional cutting were collected at six different times (December/2015, February/2016, April/2016, June/2016, August/2016 and October/2016), made 6-8 cm long, with bevel cut at the base and rectum at the apex, keeping two leaves with their area halved. The experiment was carried out in a completely randomized design with 4 replicates and 14 mini-cuttings per experimental unit. The mini-cuttings were planted in tubes with substrate containing vermiculite and carbonized rice husk (1:1) and kept in a heated greenhouse. After 120 days, the percentage of rooted mini-cuttings, number of roots per mini-cuttings, length of the three largest roots by mini-cuttings, percentage of mini-cuttings with callus, live, dead, with shoots and leaves that maintained their original leaves were evaluated. Rooting percentages of mini-cuttings were greater than 75% regardless of the season of the year in which the propagules were collected. The adventitious root formation of D. brasiliensis occurs indirectly, from the callus tissue formed at the base of the mini-cuttings. The mini-cuttings technique is recommended for the production of seedlings of the species, at any seasons of the year.

“…For an improved dissolution, the IBA solutions were made with hydroalcoholic solutions with indole-3-butyric acid with 99% purity (Vetec Química Fina, Duque de Caxias, RJ, Brazil); 50% ethyl alcohol was used as a solvent and distilled water, to complete the remainder of the solution, as adapted from Fachinello et al (2005). For a better penetration, the base of each collected cutting was kept in contact with the IBA solution for 10 s (Zem et al, 2016).…”

The objective of this work was to evaluate the effect of the collection period and of the exogenous application of indolebutyric acid (IBA) on the rooting of cuttings from adult pecan (Carya illinoinensis) plants. The experiment was carried out in a greenhouse with intermittent mist irrigation, from December 2017 to October 2018. The experimental design was completely randomized, in a 4x5 factorial arrangement, with four collection periods (spring, summer, autumn, and winter) and five concentrations of IBA (0, 2,000, 4,000, 6,000, and 8,000 mg L-1). For the cuttings collected during summer and autumn, there was a linear relationship between rooting and the increase of the IBA concentration. The best results for rooting, callus formation, mean number of roots, mean root length, and root dry and fresh mass are obtained for the cuttings collected during summer, with the application of 8,000 mg L-1 IBA on the base of each cutting, under a mist irrigation system. The rooting of cuttings from adult pecan plants with the application of IBA is possible, being an alternative propagation method for the species.

In order to improve penetration, the bases of the collected mini-cuttings were immersed for a period of 10 seconds in the hydroalcoholic solutions of IBA (ZEM et al, 2016). Subsequently, the mini-cuttings were packed in expanded polyethylene trays with 50 cells (58 x 30 x 9 cm) and a volume of 100 cm³/cell, filled with the respective substrate treatments.…”

Mini-cutting technique of tree species is an effective method of maintaining desirable features of plant matrices and uniformity. The objective of the present research was to determine substrate and concentration of indolebutyric acid (IBA) more suitable for mini-cuttings of Carya illinoinensis rooting. The experiment was carried out in a greenhouse with mist, from February to May 2018. The used experimental design was in blocks with a factorial arrangement of 3 x 5, in which three substrates were tested: carbonized rice husk, vermiculite and perlit; and five IBA concentration : 0, 2,000, 4,000, 6,000 and 8,000 mg L-1. The mini-cuttings were apical, produced from seedlings, with eight months of age. Mini-cuttings were made with two leaves cut in half and 8 to 10 cm in length. The use of IBA influenced results obtained with all substrates, except for the variable number of roots, in which only IBA effect was observed. However, higher results were obtained with IBA uses together with substrate carbonized rice husk, obtaining estimated maximum point of 91% of rooted mini-cuttings with 3,957 mg L-1 IBA concentration. For other evaluated variables, except root numbers, it was also observed superior results close to 4,000 mg L-1 IBA concentration with substrate carbonized rice husk. Results indicate the possibility of Carya illinoinensis propagation by mini-cutting technique and as an alternative for this specie plantlets production.
