Agronomic evaluation of a Hancornia speciosa Gomes germplasm collection from the Brazilian Cerrado

Abstract

Hancornia speciosa Gomes is a fruit tree native to Brazil with potential for use in cropping systems. The objective of this study was to characterize accessions of a germplasm collection by evaluating agronomic traits. The collection was planted in 2005, in an experiment with 57 progenies and four replications, totaling 192 individual accessions from 29 natural subpopulations of four botanical varieties, from the Brazilian Cerrado. The components of variance were estimated using the restricted maximum likelihood (REML) procedure. Heritability coefficients show the potential of the collection as base population for selection programs. The trait number of fruits per plant presented the highest estimated selection gain. The accessions of H. speciosa var. cuyabensis are the ones with the greatest potential for selection based on plant size and productivity. Progenies with greater development in the juvenile phase are potentially more productive in the adult phase, allowing the early selection of superior genotypes.

Clonal Fidelity and Genetic Diversity of Micropropagated Hancornia speciosa Gomes (Apocynaceae) as Evaluated by Molecular Markers

“…Despite its economic potential, H. speciosa fruits are mostly collected from nature (extractivism) since there are few orchards, which are impaired by the presence of recalcitrant seeds with a high loss of viability when stored [11,12]. The extractive harvesting of fruits (and seeds); recalcitrant seeds, which make it difficult to propagate the tree [13]; and fragmentation of habitats due to increased environmental degradation and anthropogenic action [14][15][16] are resulting in a decrease in natural occurrence areas of H. speciosa and contributing to the loss of genetic variability [13,15,17,18]. Thus, conservation strategies should be developed for this species [6,19].…”

“…Plant tissue culture has been widely used for asexual multiplication, leading to the conservation of selected or threatened genotypes to produce seedlings on a large scale [12,20,21]. Among many techniques, micropropagation is noteworthy since it can be Forests 2022, 13, 1645 2 of 17 used commercially, allowing a plant with desirable characteristics to be clonally multiplied in a short time with a reduced space and in adequate phytosanitary conditions [22][23][24].…”

Genetic control of wood quality of Myracrodruon urundeuva populations under anthropogenic disturbance

“…The coefficient of genetic variation (CV g ) expresses the extent of genetic variation in relation to the environmental characteristics (Resende et al 1991). Almeida et al (2019) mention that CV g show good selection potential when the evaluated traits are significant, in the case of BWD and H/S ratio (Tables 1 and 2). The coefficient of experimental variation (CV e ) was considered medium, except for the H/S ratio that exceeded 20%, indicating a high variation among trees for this trait.…”

THERAPEUTICS PERSPECTIVES OF THE Hancornia speciosa GOMES

“…HS is frequently cited in ethnopharmacological inventories against gastrointestinal disorders such as diarrhea, ulcers, gastritis, and stomach pain (ALMEIDA et al, 2019a). The hydroalcoholic extract and HS bark infusion were investigated for their ability to prevent and cure gastric ulcer in rodents.…”
