“…A formação da raiz adventícia é um processo complexo e dependente de fatores como o nível de fitorreguladores endógenos, presença de carboidratos, presença ou ausência de gemas dormentes e emergência de brotações (Smart et al, 2003). Segundo Hartmann et al (2011), raízes adventícias em estacas de plantas com crescimento secundário se originam a partir do tecido jovem do floema secundário, dos raios vasculares, do câmbio ou dos calos produzidos na base das estacas.…”

RESUMO -Uma das ameaças ao cerrado é a exploração de certas espécies nativas, que tem sido feita de forma extrativista e muitas vezes predatória, tornando-se imprescindíveis ações no sentido de se fazer o cultivo e domesticação destas espécies. Dentre as inúmeras frutíferas nativas que possuem alto potencial para exploração comercial, destaca-se a gabirobeira, que se encontra sob forte pressão devido ao impacto causado pela fragmentação das suas populações, seja pelo extrativismo inadequado, ou pela expansão das fronteiras agrícolas. O objetivo deste trabalho foi avaliar o uso de ácido indolbutírico na sobrevivência, brotação e enraizamento de estacas de gabirobeira. Foram coletadas estacas lenhosas de gabirobeiras da coleção do banco de germoplasma de Campomanesia spp. da UFG-Regional Jataí. Utilizaram-se estacas das espécies Campomanesia adamantium e Campomanesia pubescens segmentadas em ramos de 15 cm de comprimento contendo um par de folhas na parte apical e selecionadas as estacas que apresentavam diâmetro médio de 2,8 6 ± 1,29 cm. O experimento foi conduzido em delineamento inteiramente casualizado para cada espécie em estudo com 5 tratamentos e 4 repetições com 8 estacas/parcela. Os tratamentos foram compostos por 0, 800, 1600, 2400 e 3200 mg/L de Ácido indolbutírico (AIB). As estacas foram tratadas nas doses de Ácido indolbutírico (AIB), com 15 segundos de imersão. Após tratamento com AIB as estacas foram plantadas em bandejas de isopor com as bases perfuradas contendo como substrato areia lavada. Durante todo o período experimental foi utilizado o sistema de nebulização intermitente. Sessenta dias após a instalação do experimento as estacas foram avaliadas, quanto a Brotação, sobrevivência das estacas, porcentagem de enraizamento e porcentagem de calejamento. O uso de AIB em estacas de gabirobeiras proporcionou maior percentagem de brotação bem como maior sobrevivência das estacas, porém não proveu enraizamento.Palavras-chave: Campomanesia adamantium, Campomanesia pubescens, cerrado, fruteira nativa, propagação.

“…According to Smart et al (2003), vegetative propagation is the most appropriate method to disseminate vine cultivars around the world. However, for the introduction and establishment of vine plants in a specific area, it is very important to determine the influence of the treatments used on the rooting of cuttings from different rootstocks because each can respond differently in specific climate and soil conditions.…”

2,4-dichlorophenoxyacetic acid as an alternative auxin for rooting of vine rootstock cuttings

2014

-Viticulture is an important agricultural activity in semiarid northeastern Brazil, and the quality and ease of vine propagation are very important in this context. This study evaluated the use of 2,4-dichlorophenoxyacetic acid (2,4-D) as an alternative to indolebutyric acid (IBA) in the rooting of vine rootstock cuttings. The trial was conducted at the Universidade Federal de Sergipe (São Cristóvão-SE) between January and March 2010 with cuttings of the rootstocks of 'IAC-766', 'IAC-572', and 'Paulsen 1103' treated with 2,4-D or IBA applied at concentrations of 0, 1000, 2000, or 3000 mg•L -1 for 5 s and planted in a field on washed sand. At 56 days after planting, the percentages of rooted, sprouted, callused, and dead cuttings were evaluated, and also the average number and length of the rooted cuttings. The results showed that 2,4-D was not superior to IBA in the characteristics wanted for the rooting process of the vine rootstock cuttings. The vine rootstocks showed potential for propagation by cutting without auxin application. It was observed that the high concentrations were the worst for the rooting of the cuttings.

“…Use of appropriate auxin hormone in the production of cutting plays a key role in the rooting of many species as it can increase the amount of carbohydrate carried to the bottom of the cutting and adventitious root formation (Pal, 1995;Gunes, 2000;Smart et al, 2003;Rout, 2006). The most widely used growth regulatory substances in the rooting of ornamental plants are Indol Butyric Acid (IBA), Indol Acetic Acid (IAA) and NAA hormones from auxin group (Hartman et al, 1997;Kaynak and Ersoy, 1997).…”

Aim: To evaluate the effect of different rooting media and naphthalene acetic acid on rooting abilities and shoot growth of Nerium oleander .Methodology: Petite Red and Petite Salmon (Dwarf Nerium), the experiment was designed randomly to obtain data from three replicates (ten cuttings per replicate). The cuttings taken during mid February were -1 rooted at different concentrations of NAA (500 and 1000 mg l ) and in growth media (peat, per lite and municipal sewage sludge) for 45 days. The shoot length and number, fresh and dry weight of shoots, rooting ratios, root number and length, fresh and dry weight of roots were measured.-1 Results:The results showed that the best rooting medium was peat and 500 mg l of NAA increased rooting ratio by 60%, no difference was found between other two NAA concentrations. Moreover, in both -1 varieties, peat growth media plus 500 mg l NAA yielded the best results and addition of NAA positively affected shoot fresh and dry weight. Interpretation:On the basis of this study, it can be concluded that peat was found to be the best rooting media and NAA addition in rooting media positively affected plant growth. Moreover, recycled municipal sewage sludge can be used in ornamental plant cultivation.cuttings
