“…The inhibitory effect caused by excessive application of IBA has been observed in other species of the genus Prunus (MINDÊLLO NETO et al, 2005;MINDÊLLO NETO et al, 2006), in some cases with concentration limits close to the obtained in the present study (2700mg L -1 ). However, this concentration is variable depending on the content of endogenous auxin in each species (ABU-ZAHRA et al, 2013), which varies depending on the age (OSTERC & STAMPAR, 2011), physiological conditions (PERROT-RECHENMANN, 2010WENDLING et al, 2014), genetic of mother plant (POP et al, 2011) and time of year (OLIVEIRA & RIBEIRO, 2013).…”

Prunus serrulata is a species widely used in the ornamentation and its economic importance is mainly due to the time of its flowering. The objective was to assess the feasibility of cutting technique for propagating P. serrulata , using stem cuttings from current-year shoots, and to estimate the maximum efficiency concentration of auxin indole butyric acid (IBA), in the promotion of rooting. Collection of plant material took place in late spring. Cuttings were made with about 8±1cm length and two leaves reduced to 50% of its original surface. Twenty one IBA concentrations have been assessed (0, 250, 500, 750, 1000, 1250, 1500, 1750, 2000, 2250, 2500, 2750, 3000, 3250, 3500, 3750, 4000, 4250, 4500, 4750 e 5000mg L-1), applied in base of cuttings, which were placed in acclimatized greenhouse. After 60 days, there was a gradual increase in the rooting percentage compared to the increment of IBA to the approximate concentration of 2700mg L-1, with results higher than 80%. In addition, low efficiency concentrations of growth regulators have resulted in fewer roots per cutting, which could compromise the survivability of the seedlings under ambient conditions. Conversely, the decrease in the percentage of callus may be an indication that root formation in P. serrulata occurs directly, without requiring callus formation and its further de-differentiation and re-differentiation in roots.

“…cuttings is influenced by genetic factors, management of the mother tree and of the rooting environment, collection season and degree of lignification of the cuttings. Due to all these factors, the results have been quite variable; however, it is possible to obtain rooting percentages higher than 70% with herbaceous, semi-hardwood or woody cuttings of scion peach tree cultivars (DUTRA et al, 2002;MINDÊLLO NETO et al, 2008), scion plum trees (MINDÊLLO NETO et al, 2006), of P. persica rootstocks (NACHTIGAL, 1999;TOFANELLI et al, 2005) and rootstocks of other species or interspecific hybrids of Prunus spp. (MAYER et al, 2001;MAYER et al, 2013;RADMANN et al, 2014a;MAYER et al, 2015).…”

Nursery trees of stone fruits (Prunus spp.) are traditionally produced by union of two distinct genotypes - the rootstock and the scion - which, by grafting, form a composite plant that will be maintained throughout of all plant life. In Brazil, the rootstocks are predominantly seed propagated and therefore usually results in heterogeneous trees for vigor and edaphic adaptation. However, with advances in rootstock breeding programs that released cultivars and certification in several countries (notably in Europe), the system will come gradually evolving for vegetative propagation (cuttings and tissue culture) and use of seeds of selected rootstocks with specific characteristics and potted nursery trees production. For scion cultivar propagation, the budding system (with its many variations) has predominantly been adopted in major producing countries. This review had as objective to comment main propagation methods adopted for rootstocks and scion in peach, nectarine and plum, and recent technical progress obtained as well as the needs of improvement for nursery tree production.

“…Em ameixeira, a estaquia é uma alternativa viável para obtenção de mudas mas a sua eficiência varia em função da cultivar e do tratamento com AIB (MINDÊLLO NETO et al, 2006) e da época de coleta das estacas (ROSSAl et al, 1997). Em pessegueiro, a eficiência da estaquia varia de acordo com a concentração de AIB utilizada, com melhores resultados obtidos nas concentrações de 2.000 a 3.000 mg L Dentro da morfogênese, a calogênese é um prenúncio importante para a formação de raízes adventícias em estacas.…”

RESUMOObjetivou-se avaliar a influência da época de coleta, tratamento com frio e doses de ácido indolbutírico (AIB) na calogênese em estacas de caquizeiro 'Fuyu'. Formulou-se a hipótese que sendo o caquizeiro uma espécie que apresenta dormência em intensidades variadas durante o outono e inverno, então o crescimento celular necessário à calogênese é influenciado pela época do ano e pelo efeito do frio, que juntos podem tornar as células responsivas à ação das auxinas. Os ramos foram coletados em 29/08 (estacas lenhosas) e 21/02 (estacas semi-lenhosas) e em cada época, metade dos ramos foi tratada com 504 horas de frio (4 a 7° C) e metade foi submetida à estaquia após tratamento com AIB (0, 1.000, 2.000 e 3.000 mg L -1 ). Determinou-se a velocidade de brotação das gemas e após 60 dias foram avaliadas a porcentagem de estacas com calo, brotadas, dormentes e mortas. A calogênese foi maior (20,83 %) nas estacas semi-lenhosas não tratadas com frio. Nas estacas lenhosas não houve formação de calos. Nas estacas semi-lenhosas a velocidade de brotação foi menor que nas estacas lenhosas mas nestas últimas houve maior mortalidade (90,04 %). O tratamento com AIB não influenciou a calogênese. Concluiu-se que a calogênese foi favorecida nas estacas semi-lenhosas não tratadas com frio. A velocidade de brotação foi mais intensa nas estacas lenhosas e tratadas com frio. As estacas semi-lenhosas apresentaram-se mais dormentes, principalmente as submetidas ao tratamento com frio. Houve um maior percentual de estacas mortas entre as estacas lenhosas tratadas com frio.Palavras-chave: Diospyros kaki L., estaquia, auxinas, brotação. ABSTRACTThe objective of this work was to evaluate the influence of collection date, chill treatment and doses of indolbutiric acid (IBA) in the calogenesis in cuttings of 'Fuyu' japanese persimmon. The japanese persimmon tree presents different intensity of bud dormancy during the autumn and winter, then the cellular growth needed to the calogenesis is influenced by the season and the chill occurence, and both can determine the cell hability to respond the auxins action. The branches were collected in August, 8 th (hardwood cuttings) and February, 2 nd (semi-hardwood cuttings) and, in each date, 50 % of branches were treated with 504 hours of chill (4 to 7° C) and the remaining branches were used to prepare the witch were then submitted to differents dosis of IBA (0, 1,000, 2,000 and 3,000 mg L -1). The velocity of budburst was determined and after 60 days the percentage of cuttings with callus, sprouted, dorment and dead were evaluated. The calogenesis occured in 20.83 % of the semi-hardwood cuttings without the chill treatment. There was not calogenesis in the hardwood cuttings. In the semi-hardwood cuttings, the velocity of budburst was smaller than the hardwood cuttings, however the last one presented 90.04 % of mortality. The IBA treatment do not influenced the calogenesis. The calogenesis was stimulated in the semi-hardwood cuttings without chill treatment. The budburst velocity was more intense in...
