ABSTRACT Rapid propagation technologies have been used to increase the supply of basic cassava (Manihot esculenta Crantz) planting material, with emphasis on the production of etiolated seedlings, use of mini-cuttings, and reduction in the size of conventional stem cuttings. This study aimed to propose an accelerated multiplication protocol based on uninodal segments (single bud), as well as to evaluate whether the physiological age of the source material affects seedling establishment and development. The experiment was conducted using a completely randomized design, in a 3 × 3 factorial arrangement, with the cultivars BRS Prata, BRS Poti Branca, and Eucalipto and three physiological ages (top, middle, and base). The basal and middle segments provided a higher survival, whereas apical segments promoted a greater vegetative performance, with plant height reaching up to 57.41 cm, in addition to greater induction of tuberization in the Eucalipto cultivar. The protocol proved to be technically feasible and allowed the estimation of a production of 343 seedlings per year from a single mother plant, exceeding the multiplication rate attributed to mini-cuttings and the conventional method.
Traditionally, peach rootstock propagation occurs sexually, resulting in genetic variability, non-uniformity among seedlings produced, longer seedling formation times and a delay in the onset of production. Vegetative propagation is an alternative technique for obtaining uniform seedlings and, consequently, more homoge...

The success of jackfruit (Artocarpus heterophyllus Lam.) grafting is strongly influenced by the physiological quality of the rootstock prior to grafting. This study aimed to evaluate the effects of 75% shading and the individual application of 50 ppm α-naphthaleneacetic acid (NAA) and 15 ppm abscisic acid (ABA) on the...

Polyploidy induction is widely used in ornamental breeding to generate novel phenotypes such as larger flowers, thicker stems, and increased vegetative biomass. Therefore, this study aimed to evaluate oryzalin-mediated chromosome doubling in in vitro Culture of Dahlia pinnata using a completely randomized 2×6 factorial...

An efficient in vitro propagation system is essential for the rapid multiplication and conservation of peony germplasm resources. In this study, young stem segments, shoot tips, and scale buds of three Paeonia suffruticosa cultivars, ‘Yu Louzi’, ‘Peng Zhouzi’, and ‘Yin Zhihong’, were used as explants to evaluate the ef...

Some clonal apple rootstocks are traditionally propagated using the layering technique. However, traditional propagation methods are seasonal and require a lot of space and labor. In addition, the multiplication rate is low with these methods, resulting in low-profit sapling production for growers. In vitro propagatio...
