“…Favorable response was reported in rooting when quick dip in indole acetic acid (IAA) was used in the propagation of tea clones (Kathiravetpillai et al 1983). Some landscape ornamental plants respond as well to foliar application of auxin as a basal quick dip (Blythe et al 2004). It is reported that application of IAA and indole butyric acid (IBA) in Gravillea showed significant difference in the formation of adventitious roots compared to control (Krisanthini et al 2006).…”

Propagation by softwood canes and cuttings is preferred as a practical system for vegetative reproduction of many ornamental plant species, despite the advances in tissue culture techniques. Dracaena purplecompacta L. is a species that has a high demand for exports. Conversely, coconut water (CW) is a rich supplement that naturally contains plant growth regulators such as indole acetic acid (IAA). The objective of this work was to evaluate the potential of CW extracts containing natural IAA, on adventitious root development in vegetative propagation of ornamental plant canes of D. purplecompacta L. Five different concentrations (28, 57, 143, 286, 571 lM of natural IAA) of CW extracts were tested. Another set of treatment was carried out with the same concentrations of authentic IAA hormone for comparison purpose. The 143-lM IAA CW extract recorded the best root induction and development. It was found that the root expression was faster (5 weeks) with the use of the novel method. In the conventional method, the canes are propagated by quick dip application of commercial product containing artificial hormone IAA and placing them on coir fiber dust beds. It takes up to 6 weeks for the canes to develop adventitious roots to the desired level. Steeping canes in 143-lM IAA CW extract improved rooting in D. purplecompacta L., and it was comparable to the application of 143-lM authentic IAA. The study indicates that adventitious root development, shoot development, and leaf emergence of D. purplecompacta L. is promoted by IAA CW extracts.

“…Soto et al (2006) também obtiveram maior número médio de raízes por estaca de F. benjamina L. à medida que a concentração de AIB aumentou de 1000 para 1500 mg L -1 , de 13,7 para 16 respectivamente; sendo que em concentrações maiores (3000 e 10000 mg L -1 ) o número de raízes por estaca diminuiu; 10,3 e 7,1, respectivamente. Blythe et al (2004) também obtiveram maior número de raízes por estaca nas plantas de Ficus tratadas (7,7) com Dip_N Grow® (4920 µmol dm -3 AIB + 2685 µmol dm -3 ANA) do que nas não tratadas (6,3).…”

Ficus benjamina L. é uma espécie ornamental amplamente utilizada no paisagismo e arborização urbana no Brasil. Este trabalho teve como objetivo avaliar o enraizamento de estacas de F. benjamina utilizando diferentes concentrações de ácido indolbutírico (AIB). As estacas foram coletadas de ramos semilenhosos e confeccionadas com 6 a 8 cm de comprimento, contendo uma folha reduzida a metade e tratadas com AIB nas concentrações de 0, 500, 1000 e 2000 mg L-1, acondicionadas em tubetes contendo vermiculita e mantidas em casa de vegetação por 53 dias. As variáveis estimadas foram porcentagem de estacas enraizadas, com calos, vivas não enraizadas, mortas, número de raízes por estaca, comprimento médio de raízes por estacas e estacas brotadas. Não houve diferença significativa entre os tratamentos para as variáveis estacas enraizadas, vivas, mortas e número de raízes por estaca. O tratamento com 2000 mg L-1 de AIB proporcionou maior comprimento médio de raízes (2,3 cm) e o tratamento com 500 mg L-1 de AIB proporcionou maior porcentagem de brotações (30%). ABSTRACT Ficus benjamina L. is a species widely used in ornamental landscaping and urban landscaping, but few studies have been developed on the efficiency of propagation of this species. This study aimed to evaluate the rooting of F. benjamina using indolebutyric acid (IBA). Cuttings were collected from semi-hardwood branches and made with 6 to 8 cm of length, containing a half leaf. The cuttings were treated with IBA at concentrations of 0, 500, 1000 and 2000 mg L-1, planted in tubes containing vermiculite and maintained in a greenhouse for 53 days. The parameters evaluated were percentage of cuttings rooted, with callus, alive and dead, number of roots per cutting, mean length of roots per cutting and sprouting. There was no significant difference between treatments for the rooted, alive and dead cuttings and number of roots per cutting. The treatment with 2000 mg L-1 IBA promoted greater root length (2.34 cm) and the treatment with 500 mg L-1 IBA showed higher percentage of sprouting (30%).

“…17 compared the rooting and initial shoot growth of stem cuttings of four tropical ornamentals using different auxin treatments. For Gardenia augusta ‘Radicans’, the best rooting was obtained using a spray containing 123.0 mg · L −1 IBA + 67.1 mg · L −1 NAA after insertion into the rooting substrate; but for Ficus benjamina , a basal quick-dip in auxin or spay applications of auxin did not provide any improvement in rooting 17 . In our study, the basal leaves were immersed in the Plant Growth Regulators at different auxin combinations for 20 min prior to leaf cutting, which greatly improved the rooting and root growth of Chinese fir leaf cuttings.…”

In order to ascertain the optimal hormone combination for Chinese fir (Cunninghamia lanceolata) leaf cuttings, an L16(4)4 orthogonal test of 6-benzylaminopurine (6-BA), 1-naphthaleneacetic acid (NAA), and indole-3-butyric acid (IBA) (0, 10, 30, or 50 mg · L−1 of each exogenous hormone) immersion for 5, 10, 15, or 20 min was conducted. Callus initiation rate and rooting promotion rate were mainly affected by treatment time, root length increase by 6-BA concentration, and bud germination rate and plantlet formation rate by NAA concentration. The expected optimal combination for callus initiation rate was 50 mg · L−1 6-BA + 0 mg · L−1 NAA + 30 mg · L−1 IBA + 10 min; for rooting promotion rate, it was 0–10 mg · L−1 6-BA + 10 mg · L−1 NAA + 30 mg · L−1 IBA + 20 min; for bud germination rate, it was 50 mg · L−1 6-BA + 0–10 mg · L−1 NAA + 0–30 mg · L−1 IBA + 20 min; and for seedling formation rate for No. 4, it was 10 mg · L−1 6-BA + 10 mg · L−1 NAA + 0 mg · L−1 IBA + 20 min. Light microscopy image analysis revealed that a cluster of primordial cells was produced 40 days after cutting, and mastoid cells developed into peninsula cells in calli that were cultured for 50 days.
