“…shows that olive cultivars behaved differently with in relation to the number of roots/cutting when treated with different calcium concentrations. In this case, Arbequina cultivar detached and its rhizogenic potential was higher than the other cultivars, a fact also highlighted in other research works performed bySilva et al (2012).Whether considered the plant nutrition aspects on adventitious roots formation, Cunha et al (2009) reported that innumerable nutrients are involved in the metabolic processes associated with root formation in cuttings. In addition, calcium and iron, copper, boron, manganese and zinc are linked to the growth and development of the root system, since they participate in cell wall formation, lignification and plant cell elongation.…”

Article AbstractNowadays the semihardwood cuttings of olive is the most used method to produce seedlings of this specie; however, it is necessary to improve the efficiency of this method to enable the intensive exploitation of this fruit crop and reduce the seedling production costs. Thus, two experiments were conducted concurrently in sand bed, under a canvased shelter of the State University of Western Paraná (Brazil) to evaluate the number and average length of roots per cuttings, the percentage of rooted cuttings, cuttings with callus and dead cuttings. In the first experiment cuttings of olive cultivars Arbequina, Maria da Fé and clone 2 were treated with IBA (3.0 g L -1 ) associated with calcium concentration at 0.0; 0.25; 0.50 and 1.0 mmol L -1 , implanted in a completely randomized design in a split plot design, with four replications containing ten cutting each, under intermittent mist. For this experiment the Arbequina cultivar presented the highest average number of roots per cutting and the highest percentage of rooted cuttings, but Maria da Fé cultivar promoted the highest average of cuttings with callus. In the second experiment Clone 2 cuttings were submitted to calcium (0.5 mmol L -1 ) and IBA (3.0 g L -1 ), and substrate inoculation with Azospirillum brasilense bacterium, implanted in a completely randomized design containing three replications of ten cuttings each. In this experiment, the highest percentage of rooted cuttings was obtained for IBA (3.0 g L -1 ) + A. brasilense.

“…Silva et al (2012) observaram, em seu trabalho, utilizando como indutor do enraizamento o hormônio AIB, variação entre 9,2 e 11 para NR em estacas da cultivar Grappolo 541 de acordo com os meses de abril e agosto respectivamente, não apresentando diferenças estatísticas entre eles, e com um CR de 0,6 cm. Tais resultados podem ser considerados próximos aos encontrados no presente trabalho, quando comparados ao tratamento AIB, com um comprimento médio de 0,52 cm (Tabela 2).…”

“…Koroneiki and Arbequina, for all treatments with IBA, presented low formation of roots (from 0.0 to 5.9 roots per cutting), where there was no difference from Frantoio in treatments of 2 h and 8 h (9.3 roots). Silva et al (2012), when evaluating the cuttings rooting of 35 olive tree cultivars, obtained as best results 9.6 to 1.0 roots per cutting, since for Arbequina there was an average formation of 2.4 to 6.0 roots, according to the period.…”

“…Several researches developed towards olive trees rooting have used concentrated hydroalcohol solutions of IBA (SEBASTIANI et al, 2002;OLIVEIRA et al, 2003;OLIVEIRA et al, 2009;PEIXES et al, 2011;DENAXA et al, 2012;SILVA et al, 2012), therefore, the results found vary a lot according to the dosage, the cultivar, the period of rooting, the substrate and the type of cutting, among other factors.…”

Abstract-Phytoregulators such as indole butyric acid (IBA), have been used in the process of olive tree rooting in the form of concetrated hydroalcoholic solutions. The objective of this present study was to evaluate the efficiency of a low concentration of IBA (300 mg L -1 ), diluted in a solution of only 10% of alcohol 70 o GL, in the rooting of four olive tree cultivars (Arbequina, Arbosana, Frantoio and Koroneiki), treated in different times of base immersion (0, 1, 2, 4 and 8 hours). The rooting was carried out in november 2015, in greenhouse with an irrigation system type intermittent mist chamber. The cuttings standard were 12 cm length and two pairs of leaves, planted in plastic tubings, containing carbonized rice husk as substrate. The experimental design was achieved in randomized blocks, in factorial arrangement of 4 x 5, with four replications and 12 cuttings per plot. After 70 days of rooting it was verified that the increase of treatment time affected the leaf retention, survival and rooting negativelly. Leaf retention presented positive relationship with survival and rooting. The treatment for one hour in a solution of IBA was effective in the cuttings rooting stimulus of cultivar Arbosana (66,7%). Cultivars Koroneiki and Arbequina presented low or null rooting whether or not the IBA was used. Index terms: Olea europaea L., vegetative propagation, cuttings, indolbutyric acid. Tempo de tratamento com AIB no enraizamento de estacas de cultivares de OliveiraResumo-Fitorreguladores, como o ácido indolbutírico (AIB), têm sido empregados no processo de estaquia da oliveira geralmente na forma de soluções hidroalcoólicas concentradas. O objetivo do presente estudo foi avaliar a eficiência de uma baixa concentração de AIB (300 mg L -1 ), diluído em solução com apenas 10% de álcool a 70 o GL, no enraizamento de estacas de quatro cultivares de oliveira (Arbequina, Arbosana, Frantoio e Koroneiki), tratadas por diferentes tempos de imersão da base (0; 1; 2; 4 e 8 horas). A estaquia foi realizada em novembro de 2015, em estufa com sistema de irrigação do tipo nebulização intermitente. As estacas foram padronizadas com tamanho de 12 cm de comprimento e dois pares de folhas, plantadas em tubetes plásticos contendo casca de arroz carbonizada como substrato. O delineamento experimental foi em blocos casualizados, no esquema fatorial 4 x 5, com quatro repetições e 12 estacas por parcela. Após 70 dias de estaquia, foi verificado que o aumento do tempo de tratamento afetou negativamente a retenção foliar, a sobrevivência e o enraizamento. A retenção foliar apresentou relação positiva com a sobrevivência e o enraizamento. O tratamento por 1 hora em solução de AIB foi eficiente no estímulo do enraizamento das estacas da cultivar Arbosana (66,7%). As cultivares Koroneiki e Arbequina apresentaram baixo ou nulo enraizamento, independentemente do uso ou não de AIB. Termos para indexação: Olea europaea L., propagação vegetativa, estaquia, ácido indolbutírico.
