Comparison of Old and Local Apple Varieties and Seedlings (Malus domestica Borkh.) in the Variability of Some Morphological Characters of Fruits and Seeds

Abstract

Old and local varieties of cultivated plant species selected from natural populations adapted to long-term cultivation, which represent a rich genetic potential for the development of agroecosystems and agriculture under specific conditions, resources for an environment aestheticization, landscaping and development of cultural traditions. The research focused on determining the economic value of a selected collection of old and local varieties of apple tree (Malus domestica Borkh.), widespread in Slovakia for their practical use in organic farming or as genetic resources for breeding new varieties for organic food production. For experimental evaluation, we used two collections: 1) 73 old and local varieties of apple trees concentrated and preserved ex situ in a clone repository in the village Bacúch; 2) 77 self-sown seedlings, that spontaneously emerged as a result of free pollination and are growing in situ around Nitra,

Identification of Vitamin C in Flowers and Leaves Malus Spp.

“…Just as ascorbic acid has many functions in humans, ascorbate plays many roles in plant biochemistry [7]. Almost all plants have mechanisms for ascorbic acid production, and the concentration of this metabolite varies widely [8,9].…”

Influence of Variety on Total Polyphenols Content and Antioxidant Activity in Apple Fruits (Malus domestica Borkh.)

“…Apples (Malus domestica Borkh.) are widely cultivated throughout the world for their well-known nutrition and refreshing taste (Moscetti et al, 2018), and they are a highly researched crop within the scientific community (Havryliuk and Kondratenko, 2019;Horčinová Sedláčková et al, 2020;Horčinová Sedláčková et al, 2021). These fruits are not consumed just fresh; approximately one-third of them are processed into various goods, from which beverages belong to the most popular (Candrawinata et al, 2012).…”
