In order to evaluate the morphological characteristics of edible asparagus, individual plants within Taleghan population were studied and compared with Mary Washington cultivar. In studied plants, flowers were appeared from early May to early June and green fruits were formed about early July. The number of seeds per red mature berry fruit, which were collected around early September, was variable from 4 to 6 between evaluated plants. The amount of mineral elements include K, Ca, Mg, Fe, Cu, Zn, Mn, Na, Li and Ba in Taleghan asparagus in mg per 100 g fresh weight were 139.4, 1.865, 53.311, 0.811, 0.214, 0.706, 0.239, 2.363, 0.767 and 0.004 respectively, which were higher than that of Mary Washington cultivar. As the moisture content increased from 8.7 to 31.2% dry basis (d.b.), the sphericity, surface area and thousand seed mass increased from 0.807 to 0.822, 30.37 to 41.15 mm2 and 21.1 to 31.24 g respectively. As the moisture content increased the bulk density, true density and porosity were found to decrease from 630 to 530 kgm-3, 1360 to 1040 kgm-3 and 53.67 to 49.03%, whereas the terminal velocity was found to increase from 9.79 to 11.44 ms-1.
