Summary: In the last five decades, the use of rootstocks and scions has changed, along with their systems of cultivation. Associated with climate change, fruit trees face new ecological and phytopathological challenges. Rootstocks affect various traits of scions and their frost tolerance, making it important to select suitable rootstocks for successful apricot production.

Summary: Turkey's geographical location and climate conditions are suitable for growing various fruit species, with apricots being the most famous. Local and foreign varieties differ significantly in terms of soluble solids and acid content. The low taste values in foreign varieties are mainly due to their genotypic structure and early harvest. There are also differences in the main sugars and acid content among different apricot varieties.

Summary: Peach and apricot, two economically important species in the Prunus genus, exhibit distinct carotenoid profiles. The β-carotene content is higher in mature apricot fruits, giving them an orange color, while peach fruits accumulate xanthophylls with a yellow color. Transcriptional analysis revealed that BCH1 gene expression is higher in peach, correlating with the carotenoid profiles. However, the enzymatic activity of BCH1 is similar in both species. Comparative analysis of the BCH1 gene promoters between peach and apricot provided insights into their promoter activity differences.

Summary: The objective of this two-year field study was to assess the effects of controlled-nitrogen (N) fertilizers releasing speed and rates on tree morphology, physiology, yield and fruit quality of apricot. The study found that a 6-month controlled-release fertilizer had comparable or better effects than conventional fertilizer on the physiology and fruit quality of apricot trees. Higher N rates increased yield but reduced fruit redness coordinate, which is important for consumer selection of ripe fruits.

Summary: This study monitored the ripening progression of apricot fruit in nine cultivars with different fruit color and ripening date through gene expression analysis. Certain genes were identified as key predictors for fruit color, anthocyanins content, and carotenoids content, providing potential RNA markers for monitoring the ripening stage and estimating pigment compounds in apricot fruit.

Summary: Japanese plum is an important temperate tree fruit that lacks self-compatible varieties and resistance to sharka disease. Interspecific crosses between Japanese plums and sharka-resistant apricot have been conducted to obtain plumcots with resistance and self-compatibility. The study obtained and characterized new interspecific plumcots, screening over 600 seedlings for hybrid verification and evaluating floral compatibility and PPV resistance. The results showed desirable characteristics in some hybrids, including self-compatibility alleles, sharka tolerance, attractive color, and different organoleptic characteristics.

Summary: The study identified three AAT loci in apricot fruit, with PaAAT1 exhibiting fruit-specific expression patterns and playing a crucial role in the production of C6 esters during ripening. Phylogenetic analysis revealed that PaAAT1 belongs to clade 3, while PaAAT2 and PaAAT3 belong to clade 1 and clade 2, respectively. Overexpressing PaAAT1 in apricot fruit resulted in decreased levels of hexenols and increased acetate production.

Summary: The excessive use of chemical fertilizers in fruit orchards has caused various problems and negative impacts on the environment, produce quality, and food safety. In order to mitigate these issues, the application of biostimulants has been reintroduced as an eco-friendly approach to improve the growth, yield, and fruit quality of tree fruits. This study investigated the effects of different concentrations of humic acid, brassinosteroids, and seaweed extract on the performance of apricot trees, and the results showed that these substances significantly improved various growth and yield parameters, as well as the physical and chemical characteristics of the fruit.

Summary: This study explores the usage of apricot kernel in Turkish coffee, aiming to increase its nutritional and functional properties. The addition of apricot kernel powder increased the phenolic content and antioxidant activity of Turkish coffee, while decreasing the acrylamide content. Panelists gave higher scores to Turkish coffee with apricot kernel. The storage stability of Turkish coffee was also improved by adding apricot kernel powder.

Summary: The study on apricot clones revealed that factors such as fruit firmness, cell wall composition, and enzyme activity contribute to the texture and softening process of apricots. Some clones showed less susceptibility to softening, making them suitable for technological valorisation in the processing industry.

Summary: Apricot fruit qualities are affected by harvest date and rapid off-tree ripening progression. The sensory quality of the fruit sold on large-scale retail channels is generally dissatisfactory. The study analyzed two different apricot genotypes to understand the changes in sensory quality during postharvest and determine the parameters that drive consumer choice. Results showed that the selected cultivars differed in sensory quality and shelf-life, with 'Portici' performing better in aroma, sweetness, and juiciness, and 'Lady Cot' standing out in terms of firmness.

Summary: Long-term examinations are crucial for understanding the genotypic and environmental factors influencing frost tolerance in apricot flowers. The study found that both genotype and year significantly impact frost tolerance, with RK being more frost tolerant and stable across years compared to CBK. The timing of flowering and frost tolerance were positively correlated, with various meteorological parameters during flowering influencing frost tolerance. Climate change also had significant impacts on local weather conditions, affecting phenological processes, flowering time, and frost tolerance in apricot flowers.
