‘Cerejeira da mata’ and ‘guabijuzeiro’ propagation by air layering

Abstract

‘Guabijuzeiro’ and ‘cerejeira da mata’ are plant species from the Myrtaceae family, with many difficulties in asexual multiplication. Thus, the aim of this study was to evaluate ‘cerejeira da mata’ (Eugenia involucrata DC.) tree and ‘guabijuzeiro’ [Myrcianthes pungens (Berg) Legrand] tree propagation by air layering, using different IBA concentrations (0, 1000 , 2000 and 3000 mg L-1) and materials to wrap the substrate (transparent plastic, black plastic and transparent plastic + aluminum foil). The experimental design for both experiments was a randomized blocks, in a 3 x 4 factorial (wrapping material x IBA concentration), with three repetitions of five air layering each. After 180 days, the percentage of rooting, length and number of roots were evaluated. Sixty days after rooting the percentage of survival plants were evaluated. The air layering technique was not efficient in the ‘guabijuzeiro’ propagation. This technique could be used in ‘cerejeira da mata’ plants without the IBA application and using transparent plastic, but with low performance.

Vegetative multiplication of the Atlantic Rainforest species Eugenia involucrata

“…These findings corroborate those reported by Hossel et al (2017), who did not verify rooting of E. involucrata, when using low or no IBA rates. Nevertheless, in the 2018 trial, the treatment without IBA application showed a small percentage of rooting (10%).…”

Vegetative propagation of Campomanesia phaea by the air-layering and grafting techniques

“…Regardless of the applied IBA rates, root formation was not observed in any air layer during both study years, only the healing of the annular region. The histological sections of the layered healing regions indicate the formation of groups of cells similar to a callus (Figure 1 A), originating from the xylem Other species, such as the guabiju [Myrcianthes pungens (O.Berg) D.Legrand] and gabiroba (Campomanesia xanthocarpa O.Berg) trees, also did not show root formation with the air layering technique (Hossel et al, 2017;Teleginski et al, 2018). However, positive results have been reported for some fruit species belonging to the Myrtaceae family, as the Plinia trunciflora (O.Berg) Kausel and Plinia cauliflora (Mart.)…”

“…For other species of the Myrtaceae family, grafting fixation is quite diverse, being of 40 to 60% for pitanga (Eugenia uniflora L.), 50% for camu-camu [Myrciaria dubia (Kunth) McVaugh], and 20 to 61% for jabuticaba (Plinia spp.) plants (Suguino et al, 2003;Franzon et al, 2010;Lattuada et al, 2010;Malagi et al, 2012;Sasso et al, 2010;Cassol et al, 2017).…”

“…Histological analyses aid in understanding the processes involved in these and other propagation techniques, identifying possible interfering factors to their successful adoption (Ribeiro et al, 2015). Although propagation assessments have been reported for other species belonging to the Myrtaceae family (Franzon et al, 2010;Lattuada et al, 2010;Cassol et al, 2015Cassol et al, , 2017Hossel et al, 2017), there are no known reports in the literature of histological analyses for cambuci plants obtained by vegetative propagation.…”

Teknik perbanyakan tanaman buah dan tanaman hias secara vegetatif untuk meningkatkan pendapatan masyarakat di era pandemi

“…Untuk memberikan akses udara dan air dapat masuk, maka plastik pembungkus di lubangi di beberapa bagian, dan dilakukan penyiraman setiap hari. Keberhasilan mencangkok dipengaruhi oleh banyak faktor antara lain umur dan ukuran batang, sifat media tanaman, suhu, kelembaban, air, dan ZPT (Hossel et al, 2017). Makin besar diameter batang, akar yang terbentuk juga lebih banyak, hal ini karena permukaan bidang perakaran yang lebih luas.…”
