Medlar has acquired increasing popularity in recent years for its edible fruits and some healing properties in modern medicine. Medlar fruits are often stored under non-cold conditions in straw. This study was conducted to determine morphological and biochemical characteristics of medlar fruits and changes in fruit quality occurring under ordinary storage conditions. For this purpose, eight types of medlar trees were evaluated. The trees were at a mature stage and productive. Morphological properties such as the fruit and seed weight (g), length, and width (mm) were measured after the harvest. Fruit soluble solid content (%) and pH values were determined at physiological maturity after harvesting, and the fruit soluble solid content was measured again at ripening (edible stage), after 25 days of storage under ordinary storage conditions (mean temperature of 10 °C and mean humidity of 65-70%). Leaf characteristics were also determined. The tree productivity was very different between the types, and it was determined to range from 5.9 and 17.8 kg. The fruit weight varied from 9.69 to 24.45 g, while the water content decreased nearly to the half of the harvest values in some genotypes. The soluble solid content changed depending on the water losses and increased during the ripening period. The seed numbers ranged from 1.7 to 4.7 among the types, and the seed weight varied from 0.12 to 0.45 g. The fruits were able to reach ripening maturity in three weeks under the ordinary storage conditions depending on the type. Thus, this method of storage is practical for the medlar producer, but the results clearly showed that the storage period was too short and that the fruit quality was negatively affected. Cold storage conditions are needed to ensure quality and a long selling time.

The strawberry tree is an evergreen shrub tree that grows on sea-facing slopes under a Mediterranean climate. It has a key role in the lives of the rural inhabitants of forested areas and is one of the most promising species for developing new approaches in cultivation for improved fruit. As a result of the growing interest of farmers, selection studies have focused on the selection of highly productive varieties of Arbutus unedo, whereby there is a requirement for the selected varieties to be propagated at a large scale. In this study, the in vitro propagation potential of the selected A. unedo genotypes, YV2 and YV4, was investigated. The best results in terms of decreasing browning with a high level of sterilization were achieved with 50% ethanol (1 min) and 20% NaCIO (12 min) for both shoot tip and nodium explants. In terms of growth performance, both genotypes displayed the highest proliferation rate in WPM medium-supplemented with BAP (2.0 mg/L) and with added IBA and GA3 (0.1 mg/L each), in which the shoot number and elongation were also the highest. YV2 microcuttings showed higher rooting rates when cultured in WPM medium, with an added 2.0 mg/L IBA, whereas the addition of 4.0 mg/L NAA was optimal for YV4. The resulting root quality was sufficient for surviving the acclimatization stage. The genotype effect was clear in all stages during the in vitro propagation for all growth parameters.

During the pandemic period, the interest in not well-known, colourful wild small fruits has increased due to their positive health effects. Within the context of the current study, eleven genotypes of the rosehip, one of these fruits, grown in nature from seeds were characterized in terms of their horticultural characteristics. As a result; fruit width, fruit length and fruit weight were found to vary between 12.96–17.25 mm; 20.74–25.49 mm and 1.39–2.72 g, respectively. While citric acid was determined as the main organic acid in all the genotypes investigated, the mean values of the examined organic acids obtained from all the genotypes were found to be as follows; citric acid (7177 mg L− 1)>, malic acid (3669 mg L− 1) > tartaric acid (1834 mg L− 1) > oxalic acid (1258 mg L− 1) > carboxilic acid (631.9 mg L− 1) > shikimic acid (157.8 mg L− 1) > ascorbic acid (155 mg L− 1) > acetic acid (20.9 mg L− 1). Ellagic acid is the dominant phenolic, measured at high levels (90.1–96.24 mg L− 1) in all the genotypes. Genotypes are categorized according to different purposes such as suitable for wine, vinegar making etc. While the pomological characteristics were determined in a high level of positive correlation among themselves, they were generally found to be negatively correlated with the phytochemical characteristics. It is thought that genotypes categorized according to different usage purposes can contribute to rosehip agriculture, industry and breeding.
