Morphological and antiradical characteristics of Rugosa rose (Rosa rugosa Thunb.) fruits canned in different kind of honeys and in beverages prepared from honey

Abstract

The aim of the work was to determined the basic morphological and morphometric traits of rugosa rose (Rosa rugosa Thunb.) and antiradical activity of fruit pulp canned in different kind of honeys and in beverages prepared from honey. In experiments there were used 4 genotypes of roses originated from arboretum Mlyňany (Slovakia). The evaluation of 11 morphometric traits of fruit showed that the average weight of the fresh fruit without pedicle reached up 5.14 – 5.46 g, the weight of pedicle was 0.05 – 0.08 g, weight of pulp and seeds 4.80 – 5.13 g, weight of calyx 0.25 – 0.31 g, length and width of fruit (16.10 – 18.13 mm, 21.38 – 22.46 mm), the number of seeds in fruit 48.45 – 71.05, thickness of pulp 2.63 – 2.97 mm. Separated fruit pulp was canned at 40 °C and 80 °C and premixed in robinia honey and honeydew honey. Beverages were prepared by mixture of fruit pulp in honey (15 g) with cold water (150 mL). Antiradical activity was determined by DPPH method in fruit pulp (in methyl alcohol and water extracts), in honeys (black locust honey and honeydew honey) and beverages. There had been confirmed statistically significant differences in morphological traits, especially in colour and shape of fruit. Antiradical activity of fresh fruit pulp in methyl alcohol extract was determined 94.59%, in water extract 89.71%. Antiradical activity of black locust honey was 7.63%, honeydew honey 6.54%. Antiradical activity was determined also adding honeydew honey and black locust honey to fresh pulp of fruit prepared at 80 °C (33.55% and 77.58%). In beverages prepared from fresh pulp, honey and water it was investigated the higher values of antiradical activity in samples with addition of honeydew honey (81.81 – 83.86%) in comparison with robinia honey (75.57 – 79.96%).

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

“…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).…”

“…(Bolvanský and Užík, 2012;Paprstein et al, 2013;Benediková et al, 2016). It is necessary to identify and evaluate genotypes based on the morphometrical and biochemical traits in various conditions, as evidenced by the many authors (Ivanišová et al, 2017;Vinogradova et al, 2017;Grygorieva et al, 2017aGrygorieva et al, ,b, 2018aFatrcová Šramková et al, 2019;Levon and Golubkova, 2019;Vergun et al, 2020).…”

“…The evaluation of plant genetic resources has been considered of prime importance, especially in those species having economic importance (Dibuz et al, 1998;Grygorieva et al, 2014Grygorieva et al, , 2017Grygorieva et al, , 2018aMonka et al, 2014;Lima et al, 2017;Ivanišová et al, 2017;Vinogradova et al, 2017;Fatrcová-Šramková et al, 2019;Brindza et al, 2019).…”

Effect of Petal Color, Water Status, and Extraction Method on Qualitative Characteristics of Rosa rugosa Liqueur

“…Rosa rugosa Thunb. (also known as rugose rose, wrinkled rose, or Japanese rose) is a 1.5–2 m tall shrub native to eastern Asia, China, Korea, and Japan, cultivated for ornamental purposes and appreciated for fragrant colorful flowers in many parts of world [ 6 , 7 ]. This species is very adaptable, showing heat and drought tolerance as well as cold hardiness and can be grown in full sun and partial shade [ 8 ].…”

“…In addition, it shows a high resistance to main pests and diseases. R. rugosa is widely cultivated for the production of flowers, fruits, and leaves, which represent a source of bioactive compounds with antioxidant potential [ 6 , 9 ]. Indeed, this species has been used in Chinese folk medicine and the food industry for centuries.…”
