Evaluation of some phytochemical, morphological characteristics and minerals content in different populations of Jujube (Ziziphus jujaba Mill.)

Jujube (Ziziphus jujube Mill.) is a valuable medicinal tree, distributed in Iran. The fruit of this plant is used in food and pharmaceutical industries. In this study, some pytochemical, morphological and minerals of 23 Jujube (J1-J23), located in the Gazeroon research station in Qom province, were analyzed. Total soluble carbohydrate (TSC) of samples varied from 5.54 to 23.36%. The highest and lowest content of TSS was obtained from J1 (36.13%) and J22 (16.1%) ecotypes, respectively. J7 ecotype had the highest amount of total acidity (TA) (3.31%). The protein amount of samples was between 5.6 (J19) and 13.5% (J7). The highest amount of N, P, K, Fe, Zn, Cu and Mn was obtained from J8 (2.16%), J8 (0.153%), J17 (1.25%), J3 (28.91 ppm), J4 (41.12 ppm), J3 (50.27 ppm), J1 (80.23 ppm) and J8 (0.35 ppm) ecotypes, respectively. Based on dendrogram from cluster analysis, the samples were divided into eight groups. The lack of consistency in cluster analysis could be due to the differences in genetic factors. Pearson’s coefficients showed total soluble carbohydrate had significant correlation with TSS. In addition, correlation between fruit diameter with fruit length and length/diameter of fruit were significantly positive. Other chemical compositions do not show correlation with fruit morphological traits.
