cross pollination in some of apples cultivar exists; also iran is near the origin of apple trees so, large genetic diversity can be seen between iranian cultivar. also very famous apple cultivar is known in iran for special flavor and taste. the name of this cultivar is golab. this research was studied in the years 2010 and 2011 in khorasan razavi province on golab apple ecotypes to evaluate ch...

Avocado (Persea americana) fruit experience a rapid and extensive loss of firmness during ripening. In this study, we examined whether the chelator solubility and molecular weight of avocado polyuronides paralleled the accumulation of polygalacturonase (PC) activity and loss in fruit firmness. Polyuronides were derived from ethanolic precipitates of avocado mesocarp prepared using a procedure t...

pomegranate (punica granatum) is an important fruit crop cultivated for fruit and processing in the iran. delaying fruit harvest of pomegranate may increase fruit losses due to fruit cracking; however, early harvest may influence physical and biochemical indices of fruit. an experiment was carried out in 2011 at ‘baghmalek’ (north west of ahwaz, khuzestan province, iran) to determine the effect...

abstract 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 qualitative characteristics such as: fruit le...

Regulated deficit irrigation (RDI) is commonly used during different phenological stages of fruit growth and development in almond trees to reduce the amount of irrigation water applied without or with only very small reductions in yield. Therefore, to study the effects of deficit and cutoff irrigation during different phenological stages of fruit growth and development in almond cv. “Mamaei” p...

such aabiotic stresses like water stress are some of the most important threats to the production of agricultural crops. it is almost very rare to find a place with no stress where plants can reach their potential yield. a water stress of 17 percent decrease yield, due to its effect upon fruit setting is notable. therefore, a study was conducted in bushehr agricultural research center (located ...

in order to investigate the effect of pruning and potassium nutrition on pumpkin grain yield and quality, a factorial experiment based on complete block design with four replications was carried out in nooshar village of ardabil province, ardabil, iran, in 2007. experimental factors include potassium nutrition in three level (0, 75 and 150 kg/ha from potassium sulfate) and stem pruning (without...

Throughout tomato domestication, a large increase in fruit size was associated with a loss of dry matter and sugar contents. This study aims to dissect the contributions of genetic variation and the physiological processes underlying the relationships between fruit growth and the accumulation of dry matter and sugars. Fruit quality traits and physiological parameters were measured on 20 introgr...

fruit productivity and quality of eight years peach and nectarine cultivars (rich lady, ryan sun, ruby diamond and venus) grafted onto cadaman-avimag, viking, atlas, gxn 15, gf 677, mrs 2/5 and nemaguard (control) rootstocks were evaluated. a split plot experimental design was used, with each rootstock/scion combination as an experimental unit. total yield, fruit size distribution, number of fr...
