Relationships of Fruit Characteristics of Rosehips (Rosa canina L.) Grown in Bolu City Center

Abstract

Rosehip (Rosa spp.) is one of the most used non-wood forest products. It is an essential source of antioxidants and vitamin C besides having a wide range of uses in folk medicine and the marmalade industry. Therefore, for many years, researchers have made efforts to find the superior genotypes of this fruit. In previous studies, classical breeding methods were used in the evaluation of the data and more modernist approaches were given little attention. In this study, fruit characteristics and their relationships of rosehip genotypes growing in Bolu city center were determined by using more modernist analysis methods (Clustering, PCA) and correlation analysis. As a result of the study, while fruit weight was positively correlated with fruit size, it had a negative correlation with the fruit flesh ratio. In cluster analysis, genotypes were collected in two different groups, and PCA analysis supported this result. Results of the study proved that multivariate analysis has come to the fore as a highly effective method for evaluating genetic resources. Furthermore, the G-5 genotype stood out with its fruit weight and size.

Morphological and Biochemical Diversity in Fruits of Unsprayed Rosa canina and Rosa dumalis Ecotypes Found in Different Agroecological Conditions

“…TPC showed strong relationships with TFC (r = 0.74 **) and DPPH (r = 0.84 **) (Table 4). Previously, Guler et al [9] used a number of rose hips and reported negative relationships between fruit SSC content and flesh weight, and positive correlation with FW and FFR. Cosmulescu et al [75] reported that there was strong relationship between antioxidant activity and total phenolic content in Rosa fruits.…”

“…Apart from edible fruit, seeds, flowers etc. valued and used as food, medicine, fodder, fuel, agriculture, tools, fencing and ritualistic aspects, [7][8][9]. Over 30 Rosa species are found within Turkey's flora, Rosa canina and Rosa dumalis are the most common and recognized for their better fruit characteristics providing a rich source of Rosa products.…”

“…Native to cold and highland areas in Turkey, Rosa canina and Rosa dumalis are widely cultivated in Turkey [10]. In the country, it is widespread from east Anatolia to the Aegean region and from the Mediterranean to the Black sea region, revealing high environmental adaptability [7,9]. Previous studies on rose hips in Turkey aimed to describe a certain degree of heterogeneity which is normally present in cross-pollinating plants in any natural population [7][8][9][10].…”

Investigations of Some Morphological, Pomological, and Physiological Parameters with Mineral Content of Different Rosa L. Taxa Grown under Greenhouse Condition

“…Pomological analyzes were carried out according to the mentioned literature (Ercisli, 1996;Gunes, 2010;Kazankaya et al, 2005;Najda and Buczwoska, 2013;Encu, 2015;Hatipoglu and Ak, 2021;Guler et al, 2021). After the harvest of rosehip/rose fruits that reached harvest maturity, the yields of the samples brought to the laboratory were determined, and the fruits of each taxon were counted and recorded.…”

Morphometric Properties Comparison of Some Turkish and Foreign Apricot Variety Grown at High Altitude

“…PCA was used to determine critical characters and to minimize the number of effective factors. Therefore, PCA has been used intensely by researchers to define critical characteristics of fruit species for the last decade (Mratinic, et al, 2011;Güler et al, 2021;Muradoğlu et al, 2021). In this study, PCA was conducted to characterize morphological characters of Turkish and foreign varieties.…”
