Sunflower is an important crop that its oil has nutritional and high economic value. Sclerotinia is important fungal disease of sunflower that reduces its growth and yield. In this study, the reaction of 100 oily sunflower lines was studied to 6 fungal isolate of sclerotinia disease. Identification of gene loci related to resistance for disease was...

Chilling injury (CI) and decay are primary postharvest problems for horticulture crops such as grape fruits during storage. In the present study brassinosteroid (BR) was used in concentration of 0, 0.75 and 1.5 ppm on fruit quality of grape cv. Rish Baba during cold storage and then the quality parameters such as CI and decay, ion leakage, lipid pe...

Basal stem rot (BSR), caused by Sclerotinia sclerotiorum and S. minor, is one of the most important fungal diseases of sunflower (Helianthus annuus L.) causing significant yield losses worldwide. Using resistant cultivars is the most effective method to manage BSR in the field. Therefore, identification of resistant genotypes and genomic regions re...

Grape as one of the important horticultural crops plays significant role in health maintenance. In this study, the effect of nitric oxide (NO) was investigated on some physio-biochemical attributes and antioxidant enzymes activities of grape fruits (cv. Rish Baba) during chilling damage. Grape fruits were treated by 0 (control), 0.25 and 0.5 mM of...

Study and evaluation of genetic diversity in European pear (Pyrus communis L.) is an important task in the pear breeding programs. This research was carried out in order to evaluate morphological, physiological and pomological variations within the some of the pre-selected European pear seedling genotypes in comparison with`Shahmivehwith`Shahmiveh'...

The aim of this study was to identify the group of highly polymorphic microsatellite markers for identification of promising sour cherries. From among 30 tested microsatellite (SSR) markers, 19 were selected to profile genetic variation in sour cherries due to high polymorphisms. Results indicated a high level of polymorphism of the accessions base...

SDS-PAGE has been proved as one of the most important parameters for studying total protein as well as storage proteins in plants. In this study, seed storage proteins (SSPs) of promising sour cherries were analysed by SDS-PAGE with the aim of evaluating the variation among them. The results showed that total SSPs varied from 9.85-27.44 mg L-1, the...

Selection of superior chance seedling genotypes is an important task in pear breeding programs. This research was carried out in order to explore and evaluate some of European pear (Pyrus communis L.) chance seedling genotypes that are primarily used as rootstock for the Asian pear (Pyrus serotina Rehd.) in Tarbiat Modares University (TMU) Asian Pe...

Currently, much of the water resources in Iran are used in agriculture. As a result, most of the water losses are related to this section. Iran is a developing country and it is located in the arid and semiarid regions of the world. In these conditions, drought and shortage of water is one of the main challenges in agricultural production. Therefor...

(This article is in Persian with English abstract): Iran has rich cherry germplasm resources and increasing the fruit quality of these trees is the goal of their breeding programs. In this study, fruit physicochemical and qualitative characteristics of 8 selected sour cherry genotypes which were collected from different regions of Iran, were invest...

Sour cherries (Prunus cerasus L.) are rich in anthocyanins and have a correspondingly high antioxidant activity and potential health benefits with respect to the prevention of many diseases, including cancers and diabetes. As one of the centres of origin of the subgenus Cerasus, Iran is rich in cherry germplasm resources. The aim of this research w...

(This article is in Persian with English abstract): Iran is a rich source of high diversity in sour cherry trees. In the direction of breeding programs of sour cherry, this study was carried out with the aim of evaluating and comparing the genetic variability of some selected Iranian sour cherry genotypes with foreign commercial cultivars and bette...

Iran is one of the chief origins of subgenus Cerasus germplasm. In this study, the genetic variation of new Iranian sour cherries (which had such superior growth characteristics and fruit quality as to be considered for the introduction of new cultivars) was investigated and identified using 23 intersimple sequence repeat (ISSR) markers. Results in...

Currently, much of the water resources in Iran are used in agriculture. As a result, most of the water losses are related to this section. Iran as a developing country is located in the arid and semi-arid regions in the world. In these conditions, drought and water deficit is one of the main challenges in agricultural production. Therefore, develop...

Considering to importance and high genetic diversity of Pear (Pyrus communis L.) in Iran, a study was conducted on the effect of genotype on fruit physicochemical properties and qualitative characteristics of six mature European Pear genotypes in Teheran, Iran environmental conditions. In this study some physicochemical fruit properties and qualita...
