The aim of this work was to evaluate the effect of different cutting lengths, the use of biostimulants and diameter of cuttings on hops vegetative propagation. The work was conducted in a greenhouse at the Center for Agricultural Sciences (CCA) at the Federal University of Santa Catarina (UFSC), in Florianópolis/SC, Brazil, between October 2019 and January 2021. In experiment 1, cuttings with one, two and three buds were tested, with and without application of biostimulant SprintAlga TS® (Biolchim) in Brewer's Gold and Cascade cultivars. In experiment 2, cuttings with diameter of 1.5 cm, 2.5 cm and 3.5 cm were tested for Northern Brewer cultivar. In both experiments, survival, rooting, root length, root quality, number of shoots and shoot length were evaluated. In experiment 1, Cascade had lower survival, rooting and development compared to Brewer's Gold. The use of biostimulant increased survival and rooting rates of both cultivars. For Brewer's Gold the use of biostimulant improved root quality and increased shoot number, root and shoot length. For Brewer's Gold, 3-bud cuttings improved root quality and increased number of shoots. For Cascade, 1-bud cuttings showed the highest survival, rooting and development rates. In experiment 2, the highest rates of survival, rooting and the longest root length were obtained with 1.5 cm diameter cuttings. Larger diameter cuttings (2.5 and 3.5 cm) produced fewer shoots, but longer shoots.

“…The results of this study indicated that perlite:peat (total porosity 70%, waterholding capacity 30%) and perlite (total porosity 75%, waterholding capacity 20%) are optimal for 'Gisela 5' hardwood cuttings. Tofanelli et al (2003) tested six rooting substrates (sand, carbonized rice husk, vermiculite, sand + carbonized rice husk, sand + vermiculite, and carbonized rice husk + vermiculite) for rooting of peach hardwood cuttings and found that the highest rooting frequency was obtained with vermiculite, independent of thickness. Denny and Arnold (2001) found the perlite substrate the best for the rooting of cuttings of american smoketree (Cotinus obovatus), whereas Ercisli et al (2002) found the highest rooting percentage for kiwifruit (Actinidia chinensis) hardwood cuttings was obtained in peat + perlite and peat + sawdust substrates.…”

“…Many external factors such as cutting length and diameter, applied indole-3-butyric acid (IBA) concentration, date of cutting collection, and preheating can affect and increase rooting of hardwood cuttings of many species (Gill and Chitkara, 1990;Loach, 1988;Tofanelli et al, 2003) by influencing the endogenous auxin and carbohydrate contents of the tissues (Hartmann et al, 2002). Some bacteria such as those belonging to the genus Agrobacterium release auxin, can also have a positive effect on the rooting of cuttings (Sezai et al, 2003a(Sezai et al, , 2003b.…”

The effect of external factors on the rooting of hardwood cuttings of the ‘Gisela 5’ cherry rootstock (Prunus cerasus × Prunus canescens) was studied. Experiments were conducted with cuttings of different lengths (15, 20, 25, and 30 cm) and diameters (6 to 8, 9 to 11, and 12 to 14 mm) and with different indole-3-butyric acid (IBA) concentrations (0, 1, 2, 3, 4, and 6 g·L−1). Significantly improved rooting was achieved using cuttings 20 cm long and 9 to 11 mm in diameter collected in November or March from the upper part of the parent shoot and subsequently quick-dipped in 1 g·L−1 IBA solution. Cuttings placed vertically in perlite:peat (1:1) or perlite with bottom heat gave the best rooting percentage. No effect on callusing or rooting of cuttings was found after incubation of cutting in suspensions of Agrobacterium rubi. If the optimal combination of factors is selected, ‘Gisela 5’ can be propagated from hardwood cuttings with a rooting efficiency of ≈50%.

“…Dutra e Kersten (1996) mencionam que quantidades equilibradas de água e ar, conferidos por drenagem adequada e maior espaço poroso favorecem o desenvolvimento de estacas. Tofanelli et al, (2003), verificaram em sua pesquisa que o equilíbrio na relação água/ar promovido pela vermiculita e areia foram favoráveis à brotação de estacas de pessegueiro 'Okinawa'. Timm et al (2015) constataram em seus estudos que a vermiculita média e a vermiculita média + areia demonstraram ser substratos adequados para a formação de mudas, por miniestaquia, de porta-enxertos de pessegueiro 'Okinawa', 'Flordaguard' e 'Nemared'.…”

Presente em todas as regiões, a mandioca, tem importância fundamental na alimentação humana e animal, seja como matéria-prima para a obtenção de produtos industriais e/ou na geração de emprego e renda no campo. Em meio à relevância desta cultura para o atual cenário econômico nacional, objetivou-se com este estudo avaliar os efeitos de diferentes composições de substratos sobre o desenvolvimento de estruturas vegetativas de mandioca do tipo mesa mediante a adaptação da técnica de propagação rápida, como alternativa à oferta de mudas de melhor qualidade para comunidades tradicionais inseridas no semiárido piauiense. O experimento foi desenvolvido em ambiente protegido no Instituto Federal do Piauí, Campus Oeiras. Obedecendo ao delineamento em blocos casualizados, sendo testadas 12 composições de substratos formulados a partir da mistura de areia lavada, solo e esterco bovino. A mistura de substratos Solo + Areia lavada + Esterco bovino (1:1:2) e Areia lavada + Esterco bovino (1:2) são eficientes para o desenvolvimento vegetativo das brotações de mandioca do tipo mesa, permitem a obtenção de mudas de melhor qualidade para estabelecimento em campo e, portanto, são recomendados para produção de mudas da cultura no processo de propagação rápida.
