“…Indeed, apart from the substrate 50% Black soil + 50% Wood sawdust all the other substrates favoured root production, notably the substrates 50% Black coco + 50% Wood sawdust, 100% Wood sawdust, 50% Black soil + 50% Black-coco, 100% Black-coco and 100% Black soil. These substrates are porous and well drained, which is a beneficial characteristic for rooting cuttings (Koyama et al, 2014). The substrates 100% Black soil, 50% Black coconut + 50% Wood sawdust, and 100% Wood sawdust gave the best results on growth parameters especially the substrates 100% Black soil and 100% Wood sawdust according to the dendrogram.…”

The kola tree (Cola nitida) belongs to family Malvaceae grown mainly for its seed. It is highly prized for its socio-cultural and industrial uses. However, there is a significant high variability due to a high proportion of allogamy in the reproduction mode. The influence of substrate and genotype on kola tree cuttings has been studied in order to propagate it vegetatively. Six growing substrates: 100% Black soil, 50% Black soil + 50% Wood sawdust, 100% Wood sawdust, 50% Soil + 50% Black-Coco, 100% Black-Coco, 50% Wood sawdust + 50% Black-Coco were tested on genotypes 305 and D9L7A1 using a split-plot experimental design with genotype as main factor and substrate as subplot treatment replicated three times. The experimental unit constituted 20 cuttings. Six months after transplanting, the average success rate of tunnel cutting from the kola tree to the nursery was 76.2±7.6%. The best success rates were obtained with 100% Wood sawdust, 100% Black soil and 50% Black coco + 50% Wood sawdust substrates with 85±4.5, 80.8±6.6 and 79.7±5.8%, respectively, regardless of the plant material used. The substrates 100% Black soil and 100% Wood sawdust gave the best results on growth parameters such as aerial dry biomass, height growth, roots number and new formed leaves. It also showed that genotype D9L7A1 had a higher vegetative leaves and roots development than genotype 305. These genotypes were well suited for cutting.

“…According to Wendling & Dutra (2010), vermiculite substrate is very porous, which is a beneficial feature to the rooting of cuttings. KOYAMA et al (2014), in evaluations of the physical characteristics of different substrates, obtained greater liquid retention capacity, higher density and greater conductivity in coconut fiber in relation to vermiculite. However, these authors did not observe interaction between IBA concentrations and substrates regarding the survival and percentage of Litchi chinensis Soon rooting.…”

-Mini-cutting is a technique with large applications in various crops, mainly due to the increase in the percentage and quality of adventitious roots, reducing time for the formation of clonal seedlings. The aim of this study was to evaluate IBA levels and substrates on the rooting of UENF/CALIMAN 02 hybrid papaya mini-cuttings. To perform the experiment, papaya mini-cuttings were taken from mother plants grown in pots in greenhouse, induced to produce shoots through pruning and growth regulator applications. Mini-cuttings were fixed in vermiculite or coconut fiver substrates placed in alveolate trays with 4.5x4.5x5.0 cm cells, and styrofoam trays were placed in plastic trays where different IBA levels were added in a modified Hoagland solution. After 45 days, rooted buds were transplanted to plastic pots of 600 mL of volume with soil, sand, well-cured bovine fertilizer, in the proportion of 3:1:1, remaining for 45 days. When they were taken from pots, roots were carefully washed, and the length of shoots, length of the largest root, dried mass of shoots and radicular system and root percentage were measured. The experiment was set up in a randomized complete block 5 x 2 factorial design, with 5 IBA levels: 0; 2.5; 5.0; 7.5 and 10 mg L -1 , two substrates: vermiculite and coconut fiber, three replicates, with six plants per replicate. IBA levels of 5.0 mg L -1 and substrate vermiculite are the most adequate for the rooting of 'UENF/CALIMAN 02' papaya mini-cuttings in semi-hydroponic system in alveolate styrofoam trays with 4.5x4.5x5.0 cm cells.

Níveis de AIB e substratos no enraizamento de miniestacas de mamoeiro híbrido UENF/CALIMAN 02 em sistema semi-hidropônicoResumo -A miniestaquia é uma técnica com grandes aplicações em várias culturas, devido, principalmente, ao aumento dos porcentuais e qualidade de enraizamento adventício, reduzindo o tempo para a formação da muda clonal. O objetivo deste trabalho foi avaliar níveis de ácido indolbutírico (AIB) e substrato no enraizamento de miniestacas de mamoeiro híbrido UENF/CALIMAN 02. Para a realização do experimento, as miniestacas de mamoeiro foram retiradas de plantas matrizes cultivadas em vasos, em casa de vegetação, induzidas a produzir brotos por meio de podas e aplicações de reguladores vegetais. As miniestacas foram afixadas em substrato vermiculita ou fibra de coco em bandejas alveoladas de isopor com células de 4,5x4.5x5,0 cm. As bandejas de isopor foram então colocadas em bandejas plásticas contendo solução de Hoagland modificada onde foram adicionados diferentes níveis de AIB. Após 45 dias, os brotos enraizados foram avaliados e transplantados para vasos plásticos, de 600 mL de volume, com terra, areia e esterco bovino bem curtido, na proporção 3:1:1, nos quais permaneceram por mais 45 dias, quando foram retirados dos vasos e realizada a avaliação final, quando suas raízes foram lavadas cuidadosamente e foram coletados os dados de comprimento da parte aérea, comprimento da maior ...

“…Diversos trabalhos demonstram a eficiência da vermiculita pura ou em mistura com outros produtos como meio adequado à emissão e crescimento de raízes em estacas de diversas espécies, tais como, estacas de Litchi chinensis descritor da espécie (KOYAMA, et al 2014); pessegueiro do gênero Okinawa (CARDOSO et al 2011). Nestas espécies, os autores observaram que as estacas plantadas em vermiculita tiveram redução no tempo de permanência em casa de vegetação, pois a sobrevivência e enraizamento foram superiores.…”

RESUMO Objetivou-se avaliar a influência do substrato e tempo de avaliação no enraizamento de estacas provenientes de mudas de Schizolobium parahyba var. amazonicum. Foram produzidas mudas e obtidas estacas que foram imersas em solução de ácido indol-3-butírico (AIB) na concentração 3.000 mg L-1 durante 10 segundos e logo após, plantadas em bandejas plásticas contendo os substratos e colocadas em caixa de enraizamento. O delineamento experimental foi inteiramente casualizado, em parcela subdividida no tempo, com seis repetições e 10 estacas por parcela, com sorteio de três estacas por parcela para avaliação no tempo. Parcelas-vermiculita+fibra de coco+areia lavada (2:1:2); vermiculita+fibra de coco (1:1) e vermiculita+areia (1:1); subparcelas: 10, 15, 20, 25 e 30 dias. As variáveis analisadas foram: Percentagem de estacas enraizadas, estacas brotadas, estacas com calos, número médio de raiz, comprimento da maior raiz e comprimento do broto. A vermiculita+fibra de coco e vermiculita+fibra de coco+areia apresentaram os melhores resultados e o ponto máximo de enraizamento (80 e 85%, respectivamente) ocorreu aos 20 dias, sem incremento significativo a partir desse período. Para percentual de estacas com calos, estacas com brotos e comprimento de broto, houve diferença significativa para o tempo apenas na primeira avaliação (10 dias), não apresentando, a partir desse período, respostas significativas.
