“…The results found in this study are divergent from those presented by some authors (PENSO et al 2016, OLIVEIRA et al 2012. (2012) verified rooting percentage ranging from 1 to 77% in different substrates and cultivars considered promising for the Brazilian region of Serra da Mantiqueira, PENSO et al (2016) further reports that the percentage of rooting can vary widely within the same cultivar in response to environmental and intrinsic conditions of the plant matrix, such as in rooting of Koroneiki cultivar.…”

“…In olive trees, auxin is a limiting factor in rooting (KURD et al 2010), with indolebutyric acid (IBA) being the most commonly used. Treatment is normally performed for five seconds at the base of the cutting with a hydroalcoholic solution at the concentration of 2000 to 4000 mg L -1 (PENSO et al 2016), as OLIVEIRA et al (2012, which used 3000 mg L -1 for the rooting of promising semi-woody cuttings of olive tree for the Serra da Mantiqueira region, Brazil. A hormonal balance between synthetic growth promoters and inducers that may raise the auxin level in the tissue is necessary (KHAJEHPOUR et al 2014).…”

Plant cutting is a widely used propagation method for olive trees. Its viability depends on the capacity for the adventitious root formation of each species. Nevertheless, it is necessary to study the different characteristics of this process. The purpose of this study was to evaluate the influence of substrates on the rooting of semi hardwood stem cuttings of ten olive tree cultivars. Middle sized branches were collected from mother plants located in the Germplasm Bank of EPAMIG in Maria da Fé, MG, Brazil, and cuttings were prepared of approximately 12 cm in length, with 4-6 internodes, maintaining four leaves in the apical region. A completely randomized experimental design was used, with tree replications and 20 cuttings per plot. The experiment was conducted in greenhouses, in rooting plant beds containing a perlite and sand substrate with controlled intermittent water mist. After installation of the experiment, treatment was carried out with copper oxychloride solution at 3% to prevent possible fungus attacks. Evaluations were performed 70 days after cutting of the varieties. There was variation in rooting of olive tree cultivar cuttings. Better performance of sand was observed in the production of cuttings of olive tree cultivars Alto D'Ouro, JB1 and Galega which were also the cultivars that stood out among the genotypes studied.

“…Combining the need to increase production and consumption, while reducing imports, researchers have conducted a number of important olive studies in Brazil, on subjects such as cutting propagation (PENSO et al, 2016), indication of more favorable areas for cultivation (WREGE et al, 2015a;WREGE et al, 2015b), identification of pests (RICALDE et al, 2015) and olive and oil quality (OLIVEIRA et al, 2012 Sachet et al olive plant pathology under Brazilian climate conditions have not yet received sufficient attention. This is an important study area as increased olive cultivation in Brazil could result in increased spending and reduced production due to diseases occurrence.…”

Standard area diagram set for olive leaf spot assessment

The establishment of olive (Olea europaea) orchards in Brazil is increasing due to their economic potential and benefits to human health. However, a number of limiting factors need to be overcome, such as Olive Leaf Spot (OLS) occurrence, for olives to reach their full potential. OLS, which is caused by Fusicladium oleaginum, results in defoliation and a reduction in fruit production. This study aimed to develop a standard area diagram set (SAD) for the assessment of OLS severity under humid subtropical climate conditions. The SAD was developed with six levels of severity (1, 3, 6, 9, 12 and 15%) and OLS severity was validated by eight inexperienced raters. Using the SAD provided an increase in accuracy, precision and concordance, while also reducing the smallest difference detectable. The proposed SAD was adequate at estimating the OLS and could be a useful tool for use in epidemiological and phytopathometry studies, evaluation of control strategies and selection of resistant genotypes.

“…In woody species, the root primordia may be the origin of cells close to the vascular system of callus tissue (Hartmann et al, 2011). Thus, the formation of callus at the base of the minicuttings may be essential for the rooting process, since this capacity is indicative of the processing efficiency and tissue differentiation (Penso, Sachet, Maro, Patto, & Citadin, 2016). However, the high percentage of rooting and low percentage of callus demonstrate that there was no relationship between these parameters.…”

The objective of this study was to investigate the production of jacaranda (Jacaranda mimosifolia D. Don) plantlets by minicutting. For this, a mini-clonal hedge was established to supply sprouts for minicuttings. For adventitious rooting, the minicuttings were treated with hydroalcoholic solution of indolebutyric acid at concentrations of 0, 1000, and 2000 mg L-1 and grown in a greenhouse. The survival of minicuttings was evaluated at 30, 60, and 90 days, and rooting, callus, sprouting, leaf area, root area, aerial dry mass, root dry mass, total dry mass, and aerial/root dry mass ratio were assessed at 90 days. The rooted minicuttings were treated with different volumes of nutrient solution (0, 25, and 50 mL) and were evaluated for survival, height, diameter, leaf area, root area, aerial dry mass, root dry mass, and aerial/root dry mass ratio of the plantlets after 30 days of cultivation in a shade house and full sunlight. Jacaranda can be established in a mini-clonal hedge for the production of shoots necessary for the preparation of minicuttings. The minicuttings are rooted in a greenhouse without use of indolebutyric acid. The plantlets produced can be acclimatized in a shade house and rustified in full sun. Jacaranda plantlets can be produced by minicuttings.
