MORPHOMETRIC DESCRIPTORS AND PHYSIOLOGICAL SEED QUALITY FOR SELECTING Aspidosperma pyrifolium Mart. MATRIX TREES

Abstract: Aspidosperma pyrifolium Mart. (Apocynaceae) is a tree species with high ecological and economic potential. Therefore, the need to select trees for producing high-quality seeds is evident. In this sense, the objective of this study was to select A. pyrifolium matrices based on the morphometric descriptors of fruits and seeds and the physiological quality of seeds from a natural population. For this, 11 A. pyrifolium trees were selected, and their fruits and seeds were submitted to biometric analysis; in additio… Show more

“…Biometric variations in seeds are influenced by fruit, which are affected by environmental factors such as differences in pollination among inflorescences, strategy in nutrient use, and available water resources. As well as the genotypic diversity of populations, which can result in different phenotypic characteristics, the effect of the environment on seed development is mainly expressed by variations in size, in weight, and in physiological and health potential (BARROS et al, 2020;CORREIA et al, 2019).…”

“…o déficit hídrico e as altas temperaturas são ainda mais importantes para a perpetuação das espécies, sendo necessário que a germinação ocorra rapidamente devido à limitação de recursos no ambiente. Desta forma, vários estudos têm sido direcionados para essa temática, apontando altas velocidades de germinação em sementes de espécies nativas da Caatinga et al 2015,Correia et al 2019, Araújo et al 2020). Além dos fatores fisiológicos, a análise dos órgãos estruturais de sementes e plântulas e suas relações com o ambiente de ocorrência da espécie desempenha papel relevante em estudos sobre germinação e crescimento das plântulas (Oliveira e Paoli 2016).…”

“…Por seu turno, a biometria de sementes fornece informações importantes para a conservação e a reintrodução de espécies florestais nativas (FELIX et al, 2020). De outro modo, o potencial germinativo das sementes está relacionado diretamente com a sua qualidade fisiológica, fator importante para garantir o desenvolvimento da planta em condições de campo e conservar seu potencial fisiológico durante o armazenamento (CORREIA et al, 2019).…”
