“…There are several studies about this technique (Silva et al, 2006(Silva et al, , 2007Schuch et al, 2008); however, the in vitro propagation requires a complex installation and qualified professionals, increasing the seedlings production costs. As an alternative, the minicuttings propagation could be applied, since it requires less investiment and make a better use of propagation materials Pelizza et al, 2010;Fischer et al, 2013). Nevertheless, few studies are available concerning blueberries minicuttings propagation.…”

The nursery plants supply is one of the most important factors that limites blueberries production in some areas, due to some propagation difficulties observed on this species. In this way, this study aimed to evaluate substrates and IBA application methods on 'Powderblue' blueberries (Vaccinium ashei) minicuttings rooting, as well as to verify the rooting development in different periods. The study was divided in two experiments. The first one aimed to evaluate 'Powderblue' blueberry minicuttings rooting in three substrates (pine bark, carbonized rice husk and vermiculite) in response to two indolebutyric acid (IBA) application methods: 50% alcohol solution and talc. The second experiment aimed to evaluate 'Powderblue' blueberry minicuttings rooting using the best substrate recorded in the first trial (pine bark) and two IBA application methods associated to three periods of rooting access, in order to obtain the ideal rooting period and root development. In the first experiment the rooting percentage presented significant difference among the substrates; the higher percentage of rooted minicuttings occurred in pine bark substrate (68%). Regarding the methods used to IBA application, the talc method was more efficient to promote minicuttings rooting. In the second experiment, it was observed an increase in cutting rooting percentage from 55 to 84%, according to the evaluated seasons; however, the IBA application method did not influence the rooting percentage. Therefore, to produce 'Powderblue' blueberry plants from minicuttings it is recommended to use pine bark as substrate and talc as method to IBA application, transplanting the nurseries at 110 days after planting.

“…Mini-cutting is considered a specialization of conventional cutting. It consists of the use of plant shoots propagated via cuttings, or seedlings produced by seeds between 3 and 5 cm, with leaves and buds (Pelizza et al, 2010). In fruiting species, such as yellow passion and plum, the use of mini-cuttings has been shown to be viable (Tonietto et al, 2001;Carvalho et al, 2007;Ferriani et al, 2010).…”

The objective of this study was to evaluate the influence of length of herbaceous cuttings and substrates on the multiplication of ‘Woodard’ and ‘Briteblue’ blueberry cuttings. The experimental design was entirely randomized. Four replicates of 10 cuttings per plot in a 3x2 factorial arrangement, three cutting lengths (5, 8, and 12 cm) and two types of substrate (rice hull ash and coconut fiber) were evaluated. The cuttings were collected in two seasons: summer and fall. After the cuttings were prepared, they were placed in perforated plastic boxes containing each substrate for rooting, which were placed in a mist chamber under intermittent mist. After 158 days, the following variables were evaluated: proportion of rooted cuttings, cutting survival, leaf retention, number of roots per cutting, root mean length, root dry mass, unrooted cuttings with callus, and the proportion of sprouting cuttings. The use of 5-cm herbaceous cuttings collected in the summer and grown in rice hull optimizes the multiplication of ‘Woodard’ and ‘Briteblue’ blueberry cuttings.

“…It has also been observed that BAP at 8.9 μM improves the proliferation of shoots of Vaccinium uliginosum, with the addition of 5.8 μM of gibberellic acid (GA 3 ). Unlike the TDZ that induced a hyperhydricity of 20 -30% (Gu et al 2009), results similar to Pelizza et al (2010).…”

The disinfected axillary shoots of mortino - a wild plant species were cultured in MS with different concentrations (0.002, 0.05 and 0.1%) of methyl N-(1H-benzimidazol-2-yl) carbamate to develop an in vitro protocol for micropropagation through organogenesis. They were then placed in a concentration matrix (0.1, 1.0 and 10.0 μM) whose factorial design involved BAP and IAA in WPM. Results showed a 100% disinfection at 0.05% concentrations of carbendazim and the combination of IAA and BAP at 10 μM yielded a multiplication factor of 3.35, with rooting after seven weeks. This system showed efficient disinfection, multiplication and yielding an acceptable root system. Plant Tissue Cult. & Biotech. 30(2): 167-177, 2020 (December)
