“…Unlike observed in this experiment, when comparing substrates Plantmax ®, humus and sphagnum on rooting of layers of 'Bengal' lychee, conducted between October and January, Smarsi et al (2008) the worst results were obtained for sphagnum, reaching 96% of rooting only with the use of 2.000 mg L -1 IBA. Lima et al (2008), studying the effect of IBA doses on different substrates on the layering of Maytenus muelleri, did not obtain rooting for any of the tested substrates, including coconut fiber and sphagnum.…”

“…The formation of adventitious root is a complex process and dependent on factors such as the level of endogenous growth regulators, presence of carbohydrates, presence or absence of dormant buds and emergence of shoots (SMART et al, 2003). According to Hartmann et al (2011), adventitious roots in cuttings of plants with secondary growth originating from the young tissue of the phloem, vascular rays, vascular cambium or callus produced at the base of the cuttings.…”

“…In general, one can consider that the callus was more intense in the month of July, when there was 100% of layers with calluses and these exhibited higher dry mass when compared to the others, regardless of the substrate evaluated. Smarsi et al (2008) evaluating the effect of IBA and different substrates on vegetative propagation of lychee by layering, found lower callus when used sphagnum compared to Plantmax ® and humus. In that study, the highest percentage of callus for sphagnum was 93% at a dose of 2000 mg L -1 IBA.…”

-The aim of the study was to assess the influence of season and different substrates on rooting of air layers of lychee (Litchi chinensis Sonn.) for the production of seedlings to ensure the formation of uniform and productive orchards. Air layers were done in plants of the Bengal cultivar using leafy and healthy woody branches, with about 0.010 to 0.015 m in diameter, in which were performed complete girdling with 0.020 m wide at a distance of 0.30 to 0.40 m below the apex. Then the branches were wrapped in moistened substrate. The layering was made at six times of the year (January, March, May, July, September and November) and two substrates were used (coconut fiber and sphagnum) in a 6 x 2 factorial design in a randomized block with ten replicates. After 90 days, layers were separated from the matrix plant and evaluated for rooting and callus formation, root number, considering only the primary roots, length, area and volume of the roots, beyond the dry weight of roots and calluses. The months of January, March, September and November showed the best results for all analyzed variables related to rooting. With respect to the substrates, the only difference was in January and March to the root number and dry weight of roots, where the sphagnum showed the best results. The month of July was more conducive to the formation of calluses. The period between September and March was more suitable to the propagation of lychee, when there were rooting percentages above 90%, in addition to the formation of large amount of roots.

Foram feitos alporques em plantas da cultivar Bengal utilizando ramos lenhosos bem enfolhados e sadios, com cerca de 0,010 a 0,015 m de diâmetro, nos quais foram realizados anelamentos completos de 0,020 m de largura, a uma distância de 0,30 a 0,40 m abaixo do ápice dos mesmos. A seguir, os ramos foram envoltos por substrato umedecido. Foram avaliadas seis épocas de realização dos alporques (janeiro, março, maio, julho, setembro e novembro) e dois substratos (esfagno e fibra de coco), em um esquema fatorial 6 x 2, no delineamento em blocos casualizados, com dez repetições. Passados 90 dias, os alporques foram separados da planta-matriz e avaliados quanto à porcentagem de enraizamento e de calejamento; número de raízes, considerando-se apenas as raízes primárias; comprimento, área e volume das raízes; além da massa seca de raízes e calos. Os meses de janeiro, março, setembro e novembro apresentaram os melhores resultados para todas as variáveis relacionadas ao enraizamento analisadas. Com relação aos substratos, houve diferença apenas nos meses de janeiro e março para o número de raízes e massa seca de raízes, onde o esfagno apresentou os mel...

“…O efeito positivo das auxinas, quando aplicada no enraizamento de estacas, já é comprovado para muitas espécies, como marmelo (PIO et al, 2007), lichia (SMARSI et al, 2008), umezeiro (CHAGAS et al, 2008, fi g o (DANELUZ et al, 2009). Hartmann et al (1990) também citam que a ação inicial das auxinas culmina com a formação das raízes, que são resultantes das alterações morfogenéticas e da diferenciação das células das estacas.…”

Resumo -O camu-camu (Myrciaria dubia) é uma espécie amazônica com frutos que apresentam elevado teor de ácido ascórbico, entre 1.380 a 6.112 mg/100g de polpa seca de fruto, característica que desperta interesse para a indústria de alimentos. Para ser cultivado, há necessidade de estudos sobre sua propagação. Por isso, as respostas ao uso de ácido indolbutírico (AIB), ácido naftalenoacético (ANA) e ácido indolacético (AIA) nas concentrações de 1.000 mg L -1 , 2.000 mg L -1 , 3.000 mg L -1 , 4.000 mg L -1 e 5.000 mg L -1 , aplicados por imersão rápida, bem como ao uso de vermiculita, areia, casca de arroz carbonizada e plantmax, empregados na forma simples ou combinada, sobre o enraizamento de estacas de camu-camu, foram estudadas em experimentos conduzidos em condições de casa de vegetação, de abril a setembro de 2008, em Boa Vista-RR. Foram utilizadas estacas semi-lenhosas obtidas de ramos retirados de plantas nativas de camu-camu, coletados às margens do rio Cauamé. As estacas foram padronizadas no tamanho de 20 cm de comprimento e 0,8 cm de diâmetro, deixando-se um par de folhas no ápice. O delineamento experimental utilizado foi inteiramente casualizado. No primeiro experimento, o esquema fatorial adotado foi 3x5, constituído pelos fi toreguladores AIB, ANA e AIA com cinco concentrações, quatro repetições e 12 estacas por parcela. Para o segundo experimento, os tratamentos constituíram-se de dez substratos, utilizados na forma simples ou combinada. A utilização dos fi torreguladores aumentou o número de estacas enraizadas, sendo que a maior porcentagem (12%) foi obtida quando utilizou-se a concentração de 3.000 mg L -1 de ANA. Os fi torreguladores AIB e AIA apresentaram maior porcentagem de enraizamento nas concentrações mais elevadas. O melhor substrato para o enraizamento de estacas de camu-camu foi obtido em areia combinada com casca de arroz carbonizada ou vermiculita. Palavras-chaves -Myrciaria dubia. Reguladores vegetais. Auxinas. Raízes adventícias. CaçariAbstract -The camu-camu (Myrciaria dubia) is a species of Amazonian fruits that has elevated levels of ascorbic acid, from 1,380 to 6,112 mg/100g of dry pulp, feature that arouses the interest of food industry. To be cultivated, there is a need to study its propagation. Therefore, the responses to the addition of indole butyric acid (IBA), naphthalene acetic acid (NAA) and indole acetic acid (IAA) at concentrations of 0, 1000 mg L , 4000 mg L -1 and 5000 mg L -1 , applied by rapid dipping was evaluated. Further, the utilization of vermiculite, sand, carbonized rice hulls and commercial substrate, used individually or in combination, on the cuttings rooting of camu-camu, were studied in experiments done in a greenhouse, AprilSeptember 2008, in Boa Vista-RR. Semi-woody cuttings obtained from the branches of native plants of camu-camu, collected from the river Cauamé were used during this study. The size of the cuttings were standardized at 20 cm in length and 0.8 cm in diameter, leaving a pair of leaves at the apex. The experimental design was completel...

“…In contrast, for cuttings collected in summer, IBA application did not promote calogenesis; however, the cuttings kept in vermiculite showed a higher percentage of callus in relation to other substrates. Smarsi et al (2008), assessing 'Bengal' lychee tree by layering verified that Plantmax® substrate provided a linear increase in layerings with callus when IBA concentrations increasing too. IBA application (4000 mg L -1 ) promoted 100% of callus in layering propagation.…”

Lychee (Litchi chinensis Sonn.) propagation by cuttings is a promising alternative in commercial production of seedlings, since it is an easy procedure, in addition to enabling the standardization in the field and the reduction in production costs. Therefore the objective of this work was to evaluate 'Bengal' lychee cuttings rooting, collected in spring and summer, using different concentrations of indolebutyric acid (IBA) and substrates. The experimental design was completely randomized, in a 3 × 3 factorial arrangement, with 5 replications and 10 cuttings per plot, and the following factors were adopted: IBA concentrations (0; 1,000 and 2,000 mg L -1 ) and types of substrates (carbonized rice husk, vermiculite medium granules and coconut fiber). At 140 days, the following variables were evaluated: cuttings survival; leaf maintenance; cuttings unrooted with calli; cuttings rooted; roots number per cutting; root length and root dry mass. In addition, the pH, electrical conductivity, density and water retention capacity of the substrates were evaluated. There was no difference in IBA concentrations applied in both evaluated periods. However, in the spring, the carbonized rice husk provided highest mean for the measured variables. On the other hand, in the summer, the rooting percentage presented a lower average in all substrates (< 1%), independent of the IBA concentrations. It was concluded that the 'Bengal' lychee propagation by cutting can be carried out in the spring, using carbonized rice husk as substrate, without IBA.
