Mullein (Verbascum phlomoides L.) is a valuable medicinal plant belonging to the Scrophulariacea. In this study, the yield and active substances of flowers in Shahrekord and Sepidan regions were investigated. The experiment was based on a completely randomized design with four replications. Seeds were sown in autumn. Flowers were collected at full flowering stage for evaluation of yield and active substances. Total phenols, total anthocyanin, mucilage, total flavonoids and antioxidant activity were measured using Folin-ciocalteau, different pH, hot extraction, colorimetric aluminum, and DPPH methods, respectively. Shahrekord region had the highest flower yield (652.5 kg/h), total flavonoid (3.53 mg rutin/g dw), total anthocyanin (1.35 mg/ml) and antioxidant activity (117.42), showing significant difference with Sepidan region (P<0.05). The highest mucilage content (2.34%) was observed from Sepidan region. The results of the present study showed that climatic factors affected the yield and quality of active substances of Mullein.

In order to study the effects of zeolite, bio and organic fertilizers on the growth, yield and yield components of German Chamomile (Matricaria chamomilla L.) in organic cultivation, an experiment was conducted at the research field of Tarbiat Modares University in 2005. The factors were PGPR inoculums (inoculated and no inoculated), zeolite (0 and 9 ton/ha) and vermicompost (0, 5, 10 ton/ha). The experimental design was factorial in a randomized complete blocks design with twelve treatments and three replications. Mean comparison was carried out using Duncan’s multiple range test (at 5% level). Results showed that the highest value of flower yield (358.13), biological yield (1572.09), number of flower per plant (61.09), flower diameter (21.84) and height (45.51) were obtained with PGPR inoculums. Zeolite also showed significant effects on mentioned traits except flower diameter and harvest index. With increasing of vermicompost levels, all traits were increased as the highest value of flower yield (434.22), biological yield (1814.30), number of flower per plant (72.71), flower diameter (22.35) and height (47.91) were obtained with application of 10 ton/ha vermicompost. In addition, there were positive and synergistic interactions between vermicompost combined with PGPR and vermicompost combined with zeolite on dry flower yield, as the highest flower yield was obtained in v3b2 and v3z2 treatments with 448.73 and 448.7kg/ha, respectively.

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.

Dog-rose fruit has valuable secondary metabolites such as carotenoids. This research was aimed to determine the carotenoids and lycopene content of dog-rose (Rosa canina L.) fruit in different habitats and awareness of the diversity of these compounds. For this purpose, the fruits were collected from 60 regions of the country during 2010-2012. Carotenoids and lycopene content were measured by spectrophotometer at wavelengths of 450 and 503 nm. Total carotenoids varied from 0.195 to 1.097 ma/g Fw. The highest and lowest total carotenoids were obtained from IR34 and IR9 accessions, respectively. Lycopene ranged between 0.029-0.32 mg/g FW and the highest and lowest lycopene was obtained from IR45 and IR9 accessions, respectively. Carotenoids and lycopene content showed significant differences in the studied regions (p < 0.05). According to the results of correlation, a significant positive correlation was found between total carotenoids and lycopene (r=0.726). In our study, the studied accessions were classified into three different clusters (C1-C3). Results from this study could be used in the future breeding program of dog-rose.
