Climate change-induced waterlogging negatively impacts citrus crops. This study examined the effects of waterlogging stress and elicitor treatments on Citrus aurantium seedlings' leaf traits. Elicitors, including γ-aminobutyric acid (GABA) (5 and 10 mM), melatonin (50 and 100 µM), and potassium phosphite (KPhi) (2 and 3 g/l), were applied to seedli...

This study compared the characteristics of hermaphrodite and male pomegranate flowers in different positions during the blooming period of the ‘Malas Saveh’ and ‘Shirin Kolbad’ cultivars. Samples were collected every five days from mid-May to late June. The findings revealed that the two cultivars did not differ significantly in most of the studied...

The study investigated the effects of water deficit on the morphophysiological and antioxidant responses of some Obscure Grape Cultivars from the Caspian Basin. As water deficit increased, shoot length, leaf fresh and dry weights decreased, with the lowest values observed under the 40% field capacity (FC) treatment. Interestingly, the MY cultivar m...

Introduction and objectives Grapes are a significant source of phenolic compounds, Genetic factors primarily determine anthocyanins, and in grapes, skin color is a critical and influential factor in the large germplasm of grapes. Since about 250 cultivars of 800-1000 grape cultivars are grown in Iran, studying anthocyanin compounds in the available...

Keywords Anthocyanin Blackberry Flavonoids Harvest Season Phenol Blackberries produce several types of phytochemicals beneficial to human health and wild blackberries are richer than cultivated ones. Climatic conditions have a great impact on plants in various ways. In this experiment, wild blackberries from two regions in the west and east of Gole...

Pomegranate (Punica granatum L.) is an unrivaled crop in Iran and is grown in large quantities in most parts of the country. In this study, three cultivars of Toosefid, Kolbad and Malas Saveh were studied for different characteristics. The fruits were randomly picked from a standard orchard in the northern fields of Gorgan, based on the commercial...

The results clearly showed diverse differences among cultivars. The highest fruit weight, length, width, aril weight, aril diameter, aril fresh/dry weights, skin fresh/dry weights were found in “Gavkoshak”. The highest calyx length and skin thickness were recorded in “Galookandeh”. The “Torsh Oud”, “Faroogh”, “Galookandeh” and “Rubab” were de...

Crop growth and yield are functions of environmental factors. One of these factors is salt stress which can have harmful effects on plants. Olive is one of the most important Mediterranean plants and is moderately salt tolerant. Various mechanisms have been proposed to regulate plant adaptation and tolerance to salinity stress. Plants are more sens...

Propagation of European hazelnut by seed is influenced by some seed treatments. In this investigation, effect of stratification period and some chemicals on seeds of four hazelnut cultivars were studied. GA 3 and four months of stratification, each individually resulted in the highest germination percentage at 82.73% and 83.75%, respectively. There...

The aim of this study was to compare the physicochemical properties and antioxidant activity of five different pomegranate cultivars. Fruit mass ranged from 109.27 to 78.07 g. Peel thickness of the fruit was recorded from 5.05 to 2.70 mm. The pH, total soluble solids content, the titratable acidity content were within the range of 4.23 to 4.36, 20....

The olive fruit consists of two main tissues: flesh or mesocarp and stone. The stone itself contain the woody endocarp and seed. This study is aimed to investigate the effect of fruit growing stages on morphological characteristics and oil accumulation in different fruit tissues of olive cultivar Koroneiki. The fruits were harvested in six ripening...

This study was conducted to find the effects of fruit ripening and extraction method on the quantity and quality of the Koroneiki olive oil. The oil samples extracted in six ripening stages were used for further quality analysis. Quality assessment of the oil was conducted according to the standard methods and the composition of fatty acids was mea...

Introduction: Green pruning or summer pruning completes winter pruning, and it is conducted during the growing season. The purpose of green pruning is to maximize yield of high quality grapes. Green pruning in fruit trees improves light penetration and increases the quality of fruits. The objectives of this research were to determine the influence...

The present study investigated the effect of different factors on cracking of pomegranate. These factors included fruit skin thickness, fruit volume, fruit shape, total arils weight and Ca ion and depolymerized pectin. 'Malas-e-Saveh' and 'Yusef-Khani' as two sensitive and resistant pomegranate cultivars, respectively, were selected for this study....

Pollen incompatibility is a major problem among hazelnut cultivars and can result in considerable crop loss in hazelnut orchards. Thus, identifying the level of self-compatibility of a cultivar and compatibility between cultivars are crucial aspects to selecting the proper pollenizers. Controlled self- and cross-pollinations were carried out in thr...

Abstract Olive is one of the most ancient fruit trees and has been cultivated for its oil for thousands of years. A mature olive tree produces about 500,000 flowers. They are borne on inflorescences termed panicles. The number of flowers and their distribution on the inflorescence are specific for each cultivar but can change from year to year. The...

To examine cracking in pomegranate, fruit characteristics (skin thickness, fruit volume, skin-to-seed ratio, calcium and de-polymerized pectin) and skin biomechanical behavior of two known cultivars (Malas-e-Saveh, Yusef-Khani) were investigated. Malas-e-Saveh a sensitive cultivar was compared to Yusef-Khani which known to be very resistant to crac...

The effects of foliar application of soybean and corn oils during full bloom and two weeks later on yield, yield components and fruit juice quality of grapevine (Vitis vinifera L.) cv. 'Keshmeshi' were studied. The results showed that the application of vegetable oils decreased the berry number and increased berry length, berry weight and soluble s...

In this study, some olive cultivars and genotypes of two collections (Ganareh and Hashemabad) located in Northern Iran were studied in terms of quantity and quality of the oil. The results showed that H2 (62.0%), Shiraz 2 (56.6%) and Shiraz 1 (53.9%) had the highest percentages of oil in dry matter. H2 also had highest percentages of oil in fresh m...

Flavonoids (FGs) are a large group of polyphenolic compounds with low molecular weight, found in free and glycozidic forms in plants. Citrus fruits can be used as a food supplement containing hesperidin and flavonoids to prevent infections and boost the immune system in human body. The aim of this study was the investigation of the effect of clove...

Little work has been done to examine the position and density of pistillate inflorescences (PIs) in hazelnut. In this study, characteristics of PIs of three Iranian cultivars (“Pashmine”, “Tabestane”, and “Shastak”) and three imported cultivars (“Barcelona”, “Merveille”, and “Prostorika”) were examined over one year and compared. Overall, results s...

Paternity analysis was used to assess the self-incompatibility of the olive (Olea europaea L.) cultivar 'Kalamata' and to identify some compatible pollenisers under a Mediterranean-type climate. Eight microsatellite markers were used for genotyping three 'Kalamata' mother trees, 120 embryos, and all potential pollen donors. The identified alleles w...

Pollen tube observation was used to assess the self- and cross-incompatibility of the olive (Olea europaea L.) cultivars ‘Frantoio’, ‘Koroneiki’ and ‘Kalamata’. The pistils were harvested 1 week after hand pollination and stained with 0.1% aniline blue. The styles and ovules were separated, mounted in 80% glycerol and observed under a fluorescence...

The influence of flower position on the inflorescence on opening day, gender, and petal persistence was studied in three olive cultivars: Manzanillo, Mission, and Frantoio. In each cultivar, 45 inflorescences were checked every morning from flower opening to petal fall. Perfect flowers opened mainly in the beginning of the flower opening period, an...
