چکیده

The pear orchards in Iran, are predominantly established on the seedling rootstocks, but recently, the dwarfing pear rootstocks such as Quince A, has been received more consideration for this purpose. Further to Quince A rootstock, red hawthorn (Crataegus atrosanguinea) is compatible with some pear cultivars and meanwhile causes dwarfing effects in the cultivars when using as rootstock and demonstrates high tolerance to the drought stress. In this research, the growth and bearing of five commercial pear cultivars (Shah Miveh, Dargazi, Harrow Sweet, Spadona and Bartlett) were evaluated on Quince A, red hawthorn and seedling rootstock (as control) during 2013-15. The results demonstrated the highest dwarfing for Dargazi (64.7%) and Bartlett (24.4%) on hawthorn rootstock, compared with the seedling rootstocks. Among tested cultivars, Spadona had the highest tree heights with 296.3, 220.9 and 189.9 cm on seedling, Quince A and hawthorn rootstocks, respectively. The type of rootstock had no considerable effect on fruit size, titratable acidity (TA) and total soluble solids (TSS) in different cultivars. Regarding the highest dwarfing of cultivars on hawthorn rootstock, the lowest yield per tree was observed on this rootstock. According to the index of yield per unit trunk cross-sectional area (TCA), the highest yield efficiency was obtained in Dargazi/Quince A combination and then Dargazi/hawthorn rootstock. In fire blight free regions, Spadona/hawthorn rootstock could be considered as the most appropriate combination, due to its high efficiency and low alternate bearing.

چکیده [English]

To evaluate the effect of sodium nitroprusside on antioxidant activity and qualitative characteristics of pomegranate, an experiment was conducted based on a randomized complete block design (RCBD), with three replications in 2015 at the Agricultural and Natural Resources Research Center of Yazd, Iran. In this study, the effects of sodium nitroprusside foliar application in different concentrations (0, 10-3 and 10-4 M) were investigated and the amount of anthocyanin, vitamin C, flavonoid, phenol, titratable acidity (TA), total soluble solids (TSS), and antioxidant activity were measured after two months of storage at 5° C. The results of this experiment showed that the effect of sodium nitroprusside on the qualitative characteristics was significant. The highest amount of anthocyanin, vitamin C, flavonoid, phenol, TA, TSS, and antioxidant activity was observed in the concentration of 10-3 M sodium nitroprusside, while the least amount of these traits was obtained in the control treatment. According to the results, sodium nitroprusside can be used to maintain the quality of pomegranate fruit during the storage period.
