Research Article Morphological characterization and genetic divergence of a cashew population in Floriano, Piauí, Brazil

Abstract

Anacardium occidentale (cashew) is a tropical tree species that occurs mainly in northeastern Brazil. The species has great socioeconomic importance for rural populations. We investigated the genetic diversity of a natural cashew population in a rural area of Floriano, State of Piauí, Brazil. We quantitatively evaluated 12 natural variables related to the inflorescence, the cashew nut (fruit), and the peduncle (pseudofruit) in 35 trees (numbered sequentially G1-35). The characteristics of the peduncle (pseudofruit) appeared as the variables that most contributed to genetic divergence, while characteristics related to the inflorescence contributed less to the morphological differentiation. Multivariate statistics, employing principal component analysis evidenced that the first three principal components explained 81.72% of the total variance. Cashews G-3 ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 18 (3): gmr18348 L.A. Carneiro et al. 2 and G-8 were identified as the most divergent, with G-3 demonstrating the greatest peduncle lengths and weights.

Biometria De Sementes De Enterolobium Schomburgkii (Benth.) Benth. C

“…A biometria de sementes e frutos é uma ferramenta importante na identificação de espécies, uma vez que condições ambientais e genéticas podem estabelecer padrões morfométricos distintos em populações espacialmente disseminadas (GOMES et al, 2021). A biometria de sementes também possui grande importância para o entendimento da morfologia da espécie estudada (RAMOS E FERRAZ, 2008), direcionar tomada de decisão ao estabelecer seleção de sementes grandes e pequenas (MORAES et al, 2018), fornecer informações para o uso racional dos frutos e sementes (CARNEIRO et al, 2019) e distinguir espécies pioneiras e não pioneiras (BASKIN; BASKIN, 2014).…”

Phenotypic diversity of rosemary (Salvia rosmarinus Schleid.) accessions for qualitative characters

“…Diversity in crops has been assessed using molecular markers, morphological, agronomical, chemical and nutritional traits ( Suresh et al., 2014 ; Animasaun et al., 2015 ; Temesgen et al., 2015 ; Shimeles et al., 2016 ; Satyal et al., 2017 ; Solomon et al., 2019 ; Lee et al., 2020 ; Prasad et al., 2020 ; Zewdinesh et al., 2021 ). However, the use of morphological traits stands out as the first and the main instrument for the quantification of genetic diversity and identification of plant populations ( Gerrano et al., 2017 ; Lazaridi et al., 2017 ; Carneiro et al., 2019 ).…”
