“…The Brazilian cultivar Yoshimatsu is derived from multiple crosses involving breeding lines from Hawaii (USA) and French Guiana. This genetic material was released in 1988 after selection to adaptation to the Amazonas Basin region, tolerance to high temperatures, and bacterial wilt (Ralstonia solanacearum) resistance (Souza & Gentil, 2013).…”

Meloidogyne enterolobii (=M. mayaguensis) is an emerging plant pathogen capable of inducing root galls and yield reduction in a wide range of host species. This pathogen has also been reported as a global threat for tomato (Solanum lycopersicum) crop production mainly due to its ability to overcome the resistance meditated by the Mi-1 gene. Despite the potential importance of this nematode, sources of resistance to M. enterolobii are not yet available for breeding purposes. The main objective of the present work was to evaluate a large Solanum (section Lycopersicon) germplasm (comprising nine species and one botanic variety) aiming to identify useful sources of resistance to M. enterolobii. In the first screening assay, 101 accessions and the susceptible standard S. lycopersicum 'Santa Cruz' were inoculated and evaluated under controlled conditions. The phenotypic criteria used for evaluation were the number of root galls, gall index, number of eggs, and the reproduction factor. Plants of the 20 selected accessions were cultivated in 0.4 L pots filled with sterile soil. Inoculation procedures were identical to the first assay, but with higher inoculum pressure (3,300 eggs per plant). Three accessions with superior tolerance levels to M. enterolobii were identified viz. S. lycopersicum 'Yoshimatsu', S. lycopersicum 'CNPH 1246' and S. Pimpinellifolium CGO 7650 (= CNPH 1195). These accessions were re-evaluated against a distinct M. enterolobii population as well as against two other root-knot nematode species (M. javanica and one M. incognita race 1). Under higher inoculum pressure, 'Yoshimatsu' was found to be resistant to M. javanica and M. incognita race 1, but susceptible to M. enterolobii from guava. The other two sources displayed susceptibility to all three nematodes. Additional germplasm screening is needed since no source of stable genetic resistance to M. enterolobii was found so far.

“…With these variables is possible to obtain the real value of the cutting vigor (Souza & Gentil, 2013). For the average root length, better results were observed in cutting from basal and medium positions.…”

The objective of this study was to evaluate the asexual propagation of Dovyalis, through the use of substrates and cuttings. Three experiments were conducted in Marechal Cândido Rondon, Paraná State, Brazil, and the first experiment consisted of three removal positions of the cuttings (apical, middle and basal) x 4 Indole butyric acid (IBA) concentrations (0 mg L-1, 1000 mg L-1, 2000 mg L-1 and 3000 mg L-1); the second experiment evaluated the number of leaves in the cuttings (2, 4 and 6) x 3 cutting sizes (10, 15 and 20 cm); and the third experiment evaluated four substrates for rooting. The experiment was carried out in a randomized blocks design, with the first in a 3x4 and the second in a 3x3 factorial, respectively, containing 4 repetitions of 15 cuttings. The third experiment consisted of 5 repetitions of 15 cuttings. After the IBA treatment, the cuttings were taken to rooting in sandy beds during 70 days. The agronomical variables were evaluated. Basal and middle cuttings resulted in root systems with better development. The use of 1666 mg L-1 of IBA favors the Dovyalis cuttings rooting. Cuttings with 15 and 20 cm with four leaves favors the Dovyalis vegetative propagation. Dovyalis cuttings develop better on substrates containing latosol and vermiculite.

“…This crop can be propagated sexually by seeds (nongrafted) and asexually by cuttings and grafting. Vegetative propagation is mainly performed by the cutting method, which is more feasible to establish clonal plantations, because it makes possible to multiply selected genotypes in short time and at low cost, especially considering that this crop's lifetime has been reduced in the last years due to biotic and abiotic problems (Souza and Gentil, 2013;Morgado et al 2015).…”

Salinity is one of the most limiting abiotic stresses in the global agricultural sector. The objective of this study was to evaluate the effect of irrigation water salinity on the initial development of P. edulis Sims. seedlings propagated by seeds, grafting and cuttings. Treatments were distributed in a completely randomized design, in a 5 x 3 factorial arrangement, corresponding to 5 levels of irrigation water electrical conductivity (0.3 - control, 1.8, 3.3, 4.8, and 6.3 dS m-1) and 3 propagation methods (seeds, cuttings and grafting), with four replicates and one plant per plot. Fifty days after the imposition of treatments with saline water, plant height, number of leaves, stem diameter, total chlorophyll, stomatal conductance, relative leaf water content, total water consumption, dry matter of root, shoot and total, root length and root volume were evaluated. The increase in water salinity affected with greater intensity the growth and development variables (height, total dry matter and root volume of the plant) and the physiological characteristics (stomatal conductance) of the species Passiflora edulis, regardless of the method of propagation. Seedlings propagated by grafting showed better development compared to the other propagation methods (seeds and cuttings). The interaction between the propagation methods and water salinity affected seedlings propagated by seeds and cuttings with greater intensity.
