Aril Browning (AB) is a physiological disorder in pomegranate fruit that critically decreases fruit quality and market acceptability. This experiment was carried out in order to explore the effective pomegranate fruit quality traits associated with the AB disorder and select the suitable resistant cultivar and genotypes. Pomegranate physicochemical fruit quality attributes were assessed on 238 mature pomegranate genotypes and their correlations with the AB disorder were monitored. About 14.7% of the studied genotypes showed resistance to the AB disorder, but 68.14% showed moderate to severely susceptibility to the incidence. The intensity of the AB disorder symptoms in pomegranate genotypes was strongly correlated with physico-chemical frui
The present research was conducted in order to evaluate the effects of different amounts of cadmium (Cd) and lead (Pb) on the morpho- physiological and biochemical aspects of sweet basil. Pre-treatments of the soil with different concentrations of Cd and Pb was applied two months before starting the experiment in the greenhouse, and then seeds were sown in pots containing contaminated soil, under greenhouse conditions. The results showed that application of cadmium and lead have led to significant changes in morphological traits and reduction in physiological and quality traits including number of lateral shoots, flowering intensities and stem diameter. By increasing concentrations of Cd from 0 to 20 mg. kg-1 soils, the amount of basil cadm
The current research was conducted to evaluate the phenological, morphological and pomological diversity of some selected walnut genotypes in the north of Hamadan province during 2016-2017 growing seasons. For this purpose, 84 mature walnut genotypes were selected and evaluated based on the IPGRI and UPOV descriptors. After two years of evaluation, 12 genotypes were selected as the superior genotype. The results showed that HaRaToMa23 genotype is a late-leafing genotype with 23 days delay in compare with the reference standard genotype. In addition, three genotypes including HaRaSuSh1, HaRaToMa24 and HaRaVaAh17 were homogeneous.In term of pomological studies, nut and kernel weights and kernel percentages of superior genotypes varied from 12

The negative impact of contaminated soil with heavy metals on plant and human health is an important global concern. The aim of this study was to explore the influence of cadmium (Cd) and lead (Pb) on seed germination, morphological traits, and essential oil (EO) composition of sweet basil (Ocimum basilicum L.). Two months prior to the experiment, soils pre-treated using Cd (0, 5, 10, 20) and Pb (0, 100, 200, 400) in mg kg soil−1. Seeds were sown in the pots containing the contaminated soil under greenhouse conditions at 26 ? 6 ?C and 60–70 %RH. The amount and composition of EO were determined using Gas chromatography–mass spectrometry (GC-MS). The contaminated soil had a negative impact on seed germination, leaf area, and flowe

In pistachio flower buds is formed on the lateral and terminal branches of current growth and bearing happens on one-year-old branches. To achieve higher yield, the production and selection of the best bearing shoots is important in the orchard management. The aim of this research was to explore and determine the relationship between size and type of shoot with fruit bearing in some pistachio (Pistacia vera L.) cultivars under Khorasan Razavi climatic conditions. This research was carried out using randomized complete block design with three replications in 2012 and 2014 in pistachio collection orchard at the pistachio research station of Feizabad, Khorasan Resavi province, Iran. Three pistachio cultivars including: Abbasali, Akbari and Bad
Walnut kernel due to the chemical composition of fatty acids can be nutritionally and economically very important and has positive effect on human health. In this study, which was carried out during 2014 growing season, Eighteen walnuts genotypes in terms of fruit and kernel characteristics which were higher than “Chandler”, were selected to evaluate their oil and fatty acids. The oil was measured with Soxhlet and its variation range was between 57. 32-75 percent dry weight in walnut kernel. The type and amount of fatty acids were analyzed by Gas Chromatography (GC). Results of this study showed that kernel oil contains more than 88 percent unsaturated fatty acids. Among the identified fatty acids in walnut oil, linoleic acid (39.38-57.
The effects of different pollen sources including five cultivated almond cultivars (Genco, Tuono, 15–5, Filip Ceo, and Supernova) on quantity and quality of chemical composition of two Iranian self-incompatible cultivars (Shahrood 12 and Shahrood 21) as well as self-pollination of these cultivars were investigated. Results showed a variation in oil content and fatty acid composition between two studied cultivars. The oil content was not affected by pollination treatments but the fatty acid composition of almond oil significantly was influenced by type of the pollen source. The most common unsaturated fatty acids found in the kernels of all treatments were oleic acid (68.72–88.26%) and linoleic acid (10.57–22.36%). The type of pollen s
Plant genetic diversity is the fundamental of plant-breeding programs to improve desirable characteristics. Hence, evaluation of genetic diversity is the first step in fruit-breeding programs. Accordingly, the current study was carried out to evaluate 25 superior walnut genotypes in respect of phenotypic and cytological characteristics. For this purpose, 560 walnut genotypes in southwest of Iran were evaluated based on UPOV and International Plant Genetic Resources Institute (IPGRI) descriptor. After a 2-year primary evaluation, 25 superior genotypes were selected for future phenotypic and genome size assessment. Flow cytometry was used to estimate genome size of the selected superior genotypes. A high genetic diversity was found in walnut

In the modern commercial orchards management, the effective pollination and use of suitable pollinizer is an important task for producing the optimum crop yield. In spite of the long history of fruit culture and the rich of fruit tree germplasm in Iran, the onset of hybridization, pollination studies and the history of pollinizer application in the commercial fruit tree orchards is short, came back to 1987. The first proposal for effective pollination studies project had been submitted to University of Tehran, in the framework of MSc thesis in pomology and fruit tree breeding. The title of the project was' Selection of the best pollinizer for sweet cherry (Prunus avium L.) cultivar'Siah Mashad', had been conducted in the commercial sweet ch
