Variation of fruits morphometric parameters and bioactive compounds of Asimina triloba (L.) Dunal germplasm collection

Abstract

The objective of this study was to evaluate the morphological parameters and bioactive compounds (antioxidant activity, total polyphenol, flavonoid, and phenolic acid content) of 6 genotypes of dry Asimina triloba (L.) fruit from Slovak University of Agriculture in Nitra (Slovakia). Genotypes were obtained from the seeds that were sown in the year 2000. Their morphometric parameters were following: fruit weight from 59.00 to 241.19 g, fruit length from 50.14 to 140.11 mm, fruit diameter from 37.55 to 64.67 mm, number of fruits per cluster from 2 to 8, seed weight from 0.06 to 1.80 g, seed length from 16.33 to 29.11 mm, seed width from 9.56 to 18.33 mm, seed thickness from 4.98 to 9.75 mm, number of seeds in fruit from 4 to 16. The shape indexes of fruits were found ranging from 1.53 to 2.16. The variability of important is the average seeds weight from 7.40 to 35.61%, fruit weight from 14.84 to 32.95%, number of fruits per cluster from 18.21 to 32.54% and a number of seeds in fruit from 13.49 to 27.72%. The other characteristics are more or less stable. Total polyphenol content ranged from 22.13 to 37.36 mg GAE per g, total flavonoid content from 15.10 to 32.03 mg QE per g and phenolic acids content from 0.23 to 0.76 mg CAE per g. All tested samples exhibited DPPH radical scavenging activities with values from 2.84 to 7.04 mg TEAC per g. Antioxidant activity by molybdenum reducing antioxidant power method ranged from 97.25 to 275.41 mg TEAC per g of dry matter. Differences between the genotypes were significant in all observed parameters. This species is potential for propagation and practice used in the Slovak Republic.

“…Antioxidant is termed as a compound whose major function is to inhibit the oxidation of biological molecules (lipids, proteins or other molecules) and hence provides a defensive effect against ROS (Reactive oxygen species) such as hydrogen peroxide (H 2 O 2 ), superoxide (O 2 •− ), hydroxyl radical (OH • ), peroxyl radical (ROO • ), and singlet oxygen (1O 2 ) (Moyo et al, 2013;Brindza et al, 2019). These ROS are produced in the body either as a byproduct of normal cellular aerobic respiration or exposure to environmental factors such as pollution, radiation, cigarette smoke and herbicides (Thomas et al, 2010).…”

“…Evaluation and identification of genotypes based on morphological traits are important for the detection and selection of individuals that are suitable genetic material for hybridization and breeding program of new varieties, which contributes to the global conservation of biological diversity (Monka et al, 2014;Grygorieva et al, 2017aGrygorieva et al, ,b, 2018aMotyleva et al, 2017Motyleva et al, , 2018Ivanišová et al, 2017;Vinogradova et al, 2017;Brindza et al, 2018Brindza et al, , 2019Fatrcová-Šramková et al, 2019;Horčinová Sedláčková et al, 2020).…”
