“…Regarding the family Rubiaceae, the density of individuals of the genus Psychotria was notable in some sections of the areas sampled in Bananal and Itaberá, composing virtually monodominant communities in the understory, as was the case for Psychotria vellosiana in secondary vegetation in Bananal. Studies have demonstrated the intense propagation of Psychotria species, and the presence of clones might explain its aggregate distribution, given that species of this genus exhibit slow growth and a low seed germination rate (Almeida & Alves 2000;Coelho & Barros 2004;Nery 2010).…”

Structure of the understory community in four stretches of Araucaria forest in the state of São Paulo, Brazil

We analyzed the structure of the understory community in the Atlantic Forest sensu lato, for which phytosociological descriptions of the understory are lacking. We delineated 50 plots of 10 × 20 m each at four sites within an Araucaria forest (a subtype of Atlantic Forest), located in the municipalities of Bananal, Campos do Jordão, Itaberá and Barra do Chapéu, all of which are in the state of São Paulo, Brazil. To sample the resident species of the understory, we randomly selected five 1 × 1 m subplots within each plot, resulting in a total sampling area of 250 m 2 at each site. We identified differences among the locations, mostly due to proportional differences in growth forms, in terms of species richness and the importance values within the community. Factors potentially influencing the understory structure include macroclimatic and microclimatic conditions, as well as forest fragmentation, the abundance of deciduous trees in the canopy, the surrounding vegetation and geographic location.

“…This result corroborates Sutili et al (2018), who found higher survival rates and greater shoot and root production in Phyllanthus sellowianus and Salix X rubens species cuttings for the same period compared to the autumn/winter. Better rooting rates were also observed in spring for (live) cuttings of Psycotria nuda (Nery et al, 2014), Ficus adathodigifolia (Santos et al, 2011), Hibiscus rosa-sinensis (Pizzatto et al, 2011), and Tibouchina sellowiana (Bortolini et al, 2008).…”

Vegetative Propagation of Brazilian Native Species for Restoration of Degraded Areas

2019

Vegetative propagation by live cuttings is an alternative to reproduce native plants with the potential to be used in restoration of riparian forests and degraded areas. This propagation capacity is intrinsic to each species and is influenced by several factors, particularly the time of the year when cuttings are collected. The aim of this work was to investigate the influence of the season of the year on the vegetative propagation of live cuttings for the species Allamanda cathartica, Cephalanthus glabratus, Escallonia bifida, Ludwigia elegans, Sambucus australis, Sesbania virgata and Terminalia australis. The experiment was conducted at the Soil Bioengineering Laboratory of the Federal University of Santa Maria during two periods of the year (autumn/winter and late winter/spring). All species presented vegetative propagation capacity ranging from 23.3% to 100%, and the species generally showed better results in late winter/spring.

“…The coldest season was also the most suitable for the collection of cuttings of Drimysbrasiliensis, however, Zem et al [9] observed that it was not necessary to add IBA, already in Psychotrianuda [12]. The most appropriate time for picking was during the summer, but not differing from the spring collection, similar from the previous study Contrary to the result found, Pivetta et al [13] observed that rooting of Ne- Stuepp et al [14] studying IBA effect on Ilex paraguariensis demonstrated that autumn is the most enabling season for cuttings rooting, followed by spring and winter.…”

The objective of this study was to analyze the effect of the seasons and indol butyric acid (IBA), as well as the preparation of IBA solutions on rooting growth of "Fine Time" chrysanthemum cuttings. The first experiment was arranged in a 4 × 2 factorial scheme: IBA concentrations (0, 1000, 2000 and 3000 mg·L −1 ) during summer and winter with 4 replicates of two pots and six cuttings per pot. In the second experiment, the storage of IBA solution (1000 mg·L −1 ) at 15˚C was studied with four replicates of 10 cuttings per plot in a period of four weeks. In the third experiment, dilution and supply of IBA (1000 mg·L −1 or 1000 mg·kg −1 ) were studied; there were eight treatments: (1) IBA mixed with industrial talc; (2) IBA diluted in 50% alcohol and oven dried at 30˚C; (3) IBA diluted in 50% alcohol and oven dried at 70˚C; (4) IBA diluted in NaOH and supplied via aqueous solution; (5) IBA diluted in acetone and supplied via aqueous solution; (6) IBA diluted in alcohol 92.8% and supplied via alcoholic solution; (7) IBA diluted in alcohol 50% and supplied via alcoholic solution; (8) IBA mixed and supplied via lanolin; with four replicates of 10 cuttings per plot. Twenty-one days after cutting implementation, the following variables were evaluated: rooting percentage, number, average length and root dry mass. Statistical analysis and time-of-year averages were compared using the Tukey test at 5%; polynomial regression for IBA concentration and preparation data. The means of dilution and delivery were compared by the Scott-Knott test. Treatment with IBA at a concentration of 3000 mg·kg −1 resulted in 90% rooting in the winter and 100% in the summer for all treatments. Results suggest the concentration of 2000 mg·L −1 in the summer and 2000 and 3000 mg·L −1 during the winter provided better quality for the How to cite this paper: Nogueira, M.R., Ferraz, M.V.,
