“…High percentage of bamboo explants emitting shoots (up to 97%) had already been observed by other researchers (GARCÍA-RAMÍREZ et al, 2007;SINGH et al, 2012b;PANDEY;SINGH, 2012;SINGH et al, 2012a;HOULLOU;DE SOUZA, 2016a). In these cases, the better results may be associated with inherent characteristics of the matrix plant (SANDHU; WANI; JIMÉNEZ, 2018;ARAÚJO et al, 2019).…”

Bamboo species are an alternative for the composition of forest plantations. However, their potential has not been explored due to the hard time in producing large-scale clonal plants. Thus, the aim this work was to evaluate the in vitro establishment, bud multiplication and ex vitro rooting of Bambusa vulgaris. The first experiment tested different systemic and contact fungicide solutions, based on exposure time, during the establishment phase. Established explants were subjected to evaluation of residual fungicide effect on subcultures during the multiplication and elongation phases. The second experiment evaluated the influence of activated carbon on ex vitro survival and on adventitious rooting. Explant immersion in liquid culture medium added with 1.0 mL of fungicide for 120 hours has favored the in vitro establishment and reduced fungal contamination. On the other hand, it favored the shoot emission of shoots per explant during the multiplication phase. Both rooting induction culture medium and mini-incubator system use were effective in enabling adventitious root formation. The presence of activated carbon in the rooting induction culture medium resulted in a higher clonal plant survival rate.

“…However, Rodrigues (2018) used mini-cuttings of P. reticulata with 15 cm in length and observed lower percentages of propagule survival (13.33% for apical mini-cuttings, 18.33% for intermediate, and 16.67% for basal, N = 60). Araújo et al (2019), working with Paratecoma peroba mini-cuttings, found that 10 cm apical mini-cuttings showed the greatest survival (90%) and rooting (80%) rates, compared to shorter mini-cuttings, 90 days after staking. However, in the seedling production of Azadirachta indica by mini-cutting, Fernandes et al (2017), using three sizes of mini-cuttings (5, 8, and 11 cm), observed that the size of the propagules did not affect rooting, although seedlings produced from mini-cuttings of greater length showed higher Dickson Quality Index (DQI) values.…”

Background: Despite the importance of Plathymenia reticulata for forestry and ecological purposes, a protocol for the vegetative propagation of the species remains unclear mainly due to the low adventitious rooting of the propagules of the species. In this sense, this work aimed to evaluate the rooting of minicuttings of juvenile materials of P. reticulata and our hypothesis: (1) maintaining propagules under mist chamber for different periods affects the rooting process; (2) the mini-stump management system due to the restriction of the root system affects the production of mini-cuttings and the quality of clonal seedlings.Results: It was not necessary for more than 30 days in a mist chamber to induce rooting. The highest percentage of rooting was obtained 50 days after staking. Mini-gardens set up in suspended seedbed and tubes (280 cm 3 ) had the average mini-cuttings productivity of 4.32 and 2.06, respectively, over 270 days of exploration (monthly collections). At 120 days after staking, there was no difference in the survival and in the final quality of clonal seedlings produced. However, clonal seedlings from minigarden in tubes had higher height, leaf area, and number of first-order roots. Regardless of the minigarden management, the clonal seedling production index was 50%. Conclusion:We can conclude that P. reticulata seedling production via mini-cutting technique is possible.

“…The mini-cuttings were made with a size of 10 cm, in which the apical yolk and 100% of the leaf area were maintained (Araújo et al, 2019). After preparation, the minicuttings were disinfected by immersing, for 1 minute, in 0.5% sodium hypochlorite, then rinsing in running water, and then immersed in 0.2% fungicide.…”

“…Through DRIS indexes, it was possible to calculate the Nutritional balance index medium (NBIm), which is the sum of the DRIS indices in module, divided by the number of nutrients involved. The closer to zero the value of the NBIm, the lower the nutritional imbalance of the plants and, potentially, the higher production (Araújo et al, 2019;Malavolta et al, 1997).…”
