JIMENEZ-ZURITA, José Orlando et al. Characterization of soursop fruit (Annona muricata L.) in Tepic, Nayarit, Mexico. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.6, pp.1261-1270. ISSN 2007-0934.

Nayarit is the main producer of soursop (Annona muricata L.) worldwide; however, varieties or ecotypes present in the state are not recognized most production is done on trees rootstock. Thus, the results of a preliminary investigation on the characterization of soursop fruits (Annona muricata L.) in Tepic, Nayarit are presented. The 13 trees eight years old, which were harvested from four to seven fruits between June and July 2014. The mass of fruit in the population varied between 837.8 and 2513 g, the average pulp, peel and seed ratio was 71, 20.5 and 8.5%, respectively, in the population. The fruits were on average elliptical, with seed content between 19 and 311. Skin color of the fruit was green and slightly bright (h= 151.7 - 164.9, C*= 9.4-21.4; L*= 30.2 -45.8 ), average firmness 7.3 N, total soluble solids between 7.1 and 14 °Brix, titratable acidity average was 0.7% and pH 3.6. The cluster analysis formed 4 groups. Group four had the lowest number of seeds (41) and higher amount of SST SST (13.2 °Brix). The variables mass, size and color of the peel helped to split the groups. Soursop variability was determined with potential to obtain fruits for fresh market and industrial; thus to propagate the species.
