“…Lesions favor water absorption and plant growth regulator when treated, although the use of this technique may also lead to unsatisfactory results (Trevisan & Boldrini, 2008). Planting depth is another factor that may cause variation in rooting rates of cuttings and subsequent development in different species, as reported by Ojima & Regitano (1969) Considering numerous benefits, possibilities of use, and influence on platanus cuttings, studies on their adaptation to tropical and subtropical conditions, as well as the rhizogenic potential of this species are required for the development of simple and easy techniques to propagate this plant. Results of these studies may be beneficial for cultivation of this species, especially for small Brazilian farmers.…”

Platanus, an arboreal and deciduous plant, is widely adapted and can be used for several purposes. Despite producing viable seeds, production of platanus seedlings usually occurs through vegetative propagation; cuttings are the best and most efficient source for obtaining seedlings. Although cuttings offer a practical and easy method to obtain seedlings in different vegetable species, they are influenced by several factors, both external and internal. The present study aimed to analyze the behavior of plantain cuttings planted in sand subjected to damage or no damage at the cuttings base, and planted at depths of 20 and 40 cm. Experiment was carried out at the experimental station of horticulture and protected cultivation of UNIOESTE-Brazil, in a randomized 2×2 factorial design, which comprises both, planted at 20 cm and 40 cm depths, with 5 replicates and 5 cuttings per replicate. After 170 days of incubation, injured and non-injured cuttings, were evaluated for rooting percentage and cuttings sprouted, length of roots and medium length of stems, stem diameter, number of leaves per stem, and dry mass of roots and shoots. No significant differences were observed in cutting injury. All variables analyzed presented higher values when cuttings were planted at 20 cm depth. Results indicate that planting of platanus cuttings at 20 cm depth leads to better rooting rates and vegetative development.Key words: Plant propagation, propagation by cuttings, propagation materials, rooting potential, rhizogenesis, vegetative development. ResumoO plátano, planta arbórea e caducifólia, possui ampla adaptabilidade, podendo ser utilizada para diversas finalidades. Apesar de produzir sementes viáveis, a produção de mudas geralmente se dá através da propagação vegetativa, sendo a estaquia o melhor e mais eficiente método para obtenção de mudas da espécie. A estaquia, apesar de ser um método prático e fácil para obtenção de mudas de diferentes espécies vegetais, sofre influencia de inúmeros fatores, tanto externos quanto internos ao vegetal. Com isso, o presente trabalho buscou analisar o comportamento de estacas de plátano plantadas em leito de areia, submetidas a lesão da base da estaca ou não e profundidades de plantio de 20 e 40 cm. Para isso, montou-se um experimento na Estação Experimental de Horticultura e Cultivo Protegido da UNIOESTE, em delineamento de blocos inteiramente casualizado e esquema fatorial 2x2, constituído de estacas lesionadas e não lesionadas, estaqueadas a 20cm e 40cm de profundidade, contendo 5 repetições com 5 estacas por repetição. Passados 170 dias do plantio, avaliou-se o percentual de estacas enraizadas e brotadas; comprimento da maior raiz e comprimento médio de haste; diâmetro de haste; número de folhas por haste e massa seca de raiz e de parte aérea. Quanto à lesão nas estacas, não observou-se diferenças significativas. No entanto, para as profundidades de plantio, todas as variáveis analisadas apresentaram maiores valores quando as estacas foram plantadas a 20 cm de profundidade, concluindo...

RESUMOVisando aumentar o rendimento de mudas de figueira objetivou-se neste trabalho estudar o enraizamento de segmentos nodais caulinares, utilizando-se diferentes concentrações de AIB (ácido indolbutírico) e ferimentos entre os nós da estaca. Estacas caulinares da porção mediana de figueira 'Roxo de Valinhos' foram coletadas por ocasião da poda hibernal (julho), padronizadas com 20 cm de comprimento, diâmetro de 12 mm e cinco nós. Em metade das estacas, realizou-se um ferimento entre os nós [cortes quadrados com dimensões de 1 (um) cm]. As estacas foram tratadas com diferentes concentrações de AIB (0, 1.000, 2.000 e 3.000 mg L -1 ), e enterradas na posição horizontal, a 5 cm de profundidade, permanecendo totalmente imersas, em leito de areia umedecido, sob telado (sombrite com 50% de luminosidade). Passados 90 dias, mensurou-se a porcentagem de estacas enraizadas e brotadas, o comprimento médio das brotações, a porcentagem de nós enraizados, número médio de raízes e brotações por estaca e por nó e o rendimento de mudas (número médio de nós enraizados e simultaneamente brotados, por estaca). O enraizamento dos segmentos nodais caulinares é uma alternativa para o aumento no rendimento de mudas de figueira, devendo-se causar ferimento entre os nós e aplicação de 2000 mg L -1 de AIB. Palavras-chave: Ficus carica L.; propagação vegetativa; ácido indolbutírico. ABSTRACT ROOTING OF NODAL SEGMENTS OF FIG TREEThe aim of this work was to increase the rooting of stem nodal segments of tree seedling using different concentrations of IBA and injuries between the knots. Stem cuttings of fig tree 'Roxo de Valinhos' were collected at the moment of the hibernal pruning (July), standardized with 20 cm in length, diameter of 12 mm and five knots. In half of the stakes, an injury was done between the knots [square cuts with dimensions of 1 (one) cm]. The stakes were treated with different concentrations of IBA (0, 1.000, 2.000 and 3.000 mg L -1 ) and fully buried in the horizontal position at 5 cm of depth in moist sand under nursery (50% of brightness) condition. After 90 days, the rooting and sprouting of stakes, the length of shoots, the rooted nodes, number of roots and shoots per cutting and knot and yield of seedlings (average number of nodes rooted in sprouted cuttings) were evaluated. The rooting of nodal segments is an alternative for increasing the rooting of fig tree seedlings, being indicated an injury between knots associated to the application of 2000 mg L -1 of IBA.

Fig is a perennial fruit tree with high economic importance among horticultural crops in some countries. The fruit has a good market value, both at national and international level. The objective of this work was to evaluate the potential of vegetative propagation of fig cvs. ‘Sawari’ and ‘Tarnab Inzar’ through stem cuttings with different lengths, aiming to improve the production of nursery plants. The experiment was carried out from January to April 2017 and it was laid out in randomized complete block design with different sizes of cuttings (10, 15 and 20 cm) examined for two cultivars ‘Sawari’ and ‘Tarnab Inzar’, with three replications keeping 20 cuttings per treatment. The variables studied were number of leaves, number of roots, root length, shoot length, sprouting percentage and survival percentage. Cuttings size of fig cultivars had a significant temporal variation in the percentage of successful rooting and survival of cuttings. Based on data regarding number of leaves, number of roots, root length, sprouting percentage, it was concluded that 20 cm long cuttings collected for both cultivars are the best option for commercial production of fig nursery plants.
