“…No entanto, têm-se poucos trabalhos considerando o efeito positivo do boro quando adicionado sozinho à base das estacas de diferentes espécies vegetais. O seu maior uso em pesquisas com propagação vegetativa e com efeito positivo é conjugado com os reguladores NAA e/ou IBA (ácido indolbutírico) (Middleton et al, 1978;Jarvis et al, 1984;Ono et al, 1992a;1992b;Leonel & Rodrigues, 1993;Herrera et al, 2004).…”

Substrates and boron on the rooting of red pitaya cuttingsPitaya, a climbing fruit species belonging to the cactus family, has been largely commercialized in the Brazilian exotic fruit market. This study aimed to evaluate the effect of different substrates on the rooting of cladodes with the base immersed or not in boric acid solution. There was also evaluated the formation and initial development of roots, resulting in more vigorous, high-quality seedlings with higher survival rates. The experiment was carried out in a lath house of the Department of Plant Production, Horticulture Sector, College of Agronomical Sciences, Botucatu Campus, São Paulo State University (UNESP). The experiment was arranged in a complete randomized design, in a 4x2 (substrates x boron) factorial arrangement, with four replicates. Sixty days after the experiment establishment, shoot fresh and dry matter, root fresh and dry matter, and the highest root length were evaluated. The initial root growth and development of cuttings were affected by the substrates and boron. Sand+manure provided higher phytomass accumulation in the shoot and root system of red pitaya. Among the substrates, the treatment sand + cattle manure was the most suitable to produce more vigorous and high-quality seedlings.

“…Esse efeito também foi verificado por outros autores em trabalhos com porta-enxertos de videira (SILVA; FACHINELLO. MACHADO, 1986;LEONEL;RODRIGUES, 1993;POMMER;PINO, 1997;BOSZCZOWSKI, 2005). Outros fatores que também podem influenciar na sobrevivência das estacas é a permanência prolongada na câmara de nebulização e o excesso de umidade (HARTMANN et al, 1997 Médias seguidas da mesma letra na coluna não diferem estatisticamente pelo teste de Tukey a 5% de probabilidade.…”

Efeito do AIB no enraizamento de estacas herbáceas do porta-enxerto de videira VR 43-43 em diferentes substratos

ResumoO presente trabalho teve por objetivo avaliar o enraizamento de estacas herbáceas do porta-enxerto de videira VR 43-43 em três concentrações de AIB (0, 1000 e 2000 mg.L -1 ) e dois substratos (vermiculita e casca de arroz carbonizada). O delineamento foi o inteiramente casualizado, em arranjo fatorial 2 x 3 com cinco repetições e 10 estacas por parcela. As variáveis avaliadas foram: porcentagem de retenção foliar, porcentagem de estacas enraizadas; número de raízes por estaca; comprimento de raízes (cm); porcentagem brotação, porcentagem de estacas vivas; massa de matéria seca e fresca das raízes por estaca (g). Houve influência do substrato apenas na massa fresca e seca das raízes, com as maiores médias observadas para a casca de arroz carbonizada. Para as doses aplicadas de AIB, foi verificada maior porcentagem de sobrevivência e porcentagem de estacas enraizadas no grupo controle (sem aplicação de AIB) e com aplicação de 1.000 mg.L -1 . Não houve diferença significativa na interação entre substrato e aplicação de AIB. Conclui-se que a casca de arroz carbonizada é indicada para o enraizamento de estacas herbáceas do porta-enxerto VR 43-43, não sendo necessária a aplicação de AIB.

A randomized design was used in a 2 x 3 factorial arrangement with five replications and 10 cuttings per plot. The appraised variables were: percentage of leaf retention, percentage

“…Leonel and Rodrigues [27], in a study with grapevine rootstocks, found that the use of plant regulators provided favorable effects on rooting induction, with IBA at 2,000 ppm providing a higher percentage of rooted cuttings (88.87%) and greater root average length (84.33 mm). They also stated that cuttings treated with 1,000 mg/mL and 5,000 mg/mL of IBA + 150 mg/mL of boric acid increased rooting percentage, root length and root number, when compared with the isolated IBA treatment.…”

Abstract:The current study aimed to evaluate the effect of indole butyric acid (IBA) and boric acid to induce rooting on atemoya "Thompson" cuttings. A randomized block design with 10 treatments and four blocks was laid out. The treatments consisted in the use of different levels of IBA (i.e., 0, 500, 1,000, 2,000 and 4,000 mg/L) with or without boric acid at 150 mg/L. The cuttings were placed to root in expanded polystyrene (EPS) trays with 72 cells and kept in a greenhouse under misting. At 120 d after planting, leaf dry and fresh masses (g), root dry and fresh masses (g), percentage of rooting, live cuttings (LC), live cuttings with callus (LCC), number of roots per cuttings and number of emitted leaves (NEL) were evaluated. Data were submitted to analysis of variance and comparison of means by Tukey test at 5% probability. Results indicated no statistically significant differences in both application methods (separate or associated with boric acid) for all evaluated variables, except for LC, in which boric acid provided higher survival rates. It could be concluded that the propagation method using either separate IBA application or associated with boric acid is unsuitable to induce rooting on atemoya "Thompson" cuttings.
