The fruits of Annona squamosa L. are highly appreciated for their sweet taste and their nutritional and medicinal properties. Since the species is threatened by habitat loss, germplasm conservation is of the utmost importance. The present study aimed to characterize genetic variability among 19 accessions of A. squamosa maintained in the Active Germplasm Bank (AGB) of Embrapa Meio-Norte, Teresina, Piauí, Brazil, and to determine whether the geographical distribution of the genotypes influenced population structure. The accessions were derived from populations originally located in orchards situated some 200 km apart in three municipalities in the northeast of Brazil, namely Timon, Bom Jesus and Canto do Buriti. Leaf DNA was extracted and analyzed by inter simple sequence repeat (ISSR)-polymerase chain reaction. Nine ISSR primers generated 127 scorable bands of which 101 (79.52%) were polymorphic. The within-population diversity was high (Canto do Buriti), intermediary (Timon) and low (Bom Jesus). Unweighted pair-group method with arithmetic averages and Bayesian analysis of polymorphic bands separated the genotypes into two main clusters according to genetic distance and ancestry (vegetative- and seed-propagated groups), indicating that the geographical location of the populations did not influence the genetic diversity of the accessions. While ISSR marker-based DNA fingerprinting of the 19 studied accessions revealed a degree of genetic diversity between populations, the variability detected within each population was somewhat higher. This information will contribute to a better understanding of genetic variation and population structure of the accessions of A. squamosa in the AGB of Embrapa Meio-Norte, and provide crucial information for future conservation and genetic improvement programs of the species.

There are several banana cultivars resistant to Black Sigatoka disease and to Panama disease, but due to the lack of information regarding post-harvest characteristics, many are rejected in the market. Nitrogen and potassium fertilization may help to improve the sensory characteristics of ripe banana, but there is lack of studies on its effects on banana cultivation, especially those resistant to diseases. The aim of this study was to evaluate the post-harvest characteristics of ?Prata-Anã?, ?BRS Platina? and ?PA94-01? banana cultivars at four N and K2O fertilization levels (NK0: no fertilization, NK1: 175 and 285 kg ha-1 year-1, NK2: 350 and 570 kg ha-1 year-1, NK3: 525 and 855 kg ha-1 year-1, respectively) in three production cycles. It could be concluded that N and K doses adopted in this work did not influence the post-harvest physicochemical characteristics of ?Prata-Anã?, ?BRS Platina? and ?PA94-01? banana cultivars. Regardless of N and K doses, ?Prata-Anã?, ?BRS Platina? and PA94-01? banana cultivars presented differences regarding post-harvest physicochemical characteristics. Production cycles did not influence the physical characteristics but differed in post-harvest chemical characteristics in ?Prata-Anã?, ?BRS Platina? and ?PA94-01? banana cultivars. |
