Read More Satureja rechingeri, belonging to the family Lamiaceae, has been recently used Abstract Background and Objectives Satureja rechingeri, belonging to the Lamiaceae family, has been recently used in the pharmaceutical industry due to its high level of carvacrol in the essential oil. In order to select suitable clones for commercial cultivation in Dezful climatic conditions, in this study morphological and biological production traits of 58 clones of Satureja rechingeri were evaluated. Materials and Methods After initial screening of plant populations, 58 genotypes were selected based on their adaptation into field conditions. To evaluate the morphological and biological production traits of these clones in Dezful climatic conditions, an experiment was conducted based on randomized complete block design with three replications. Morphological and biological production traits of 58 clones were evaluated in the second year of cultivation at the flowering stage. Results Analysis of variance showed significant differences for all studied traits (p< 0.01) among 58 clones. The most important traits varied in terms of plant height (27.83-71.50 cm), fresh weight (20.26-289.71 g/p), flower and leaf weight (4.05 to 83.62 g/p), and plant oil yields (0.07 to 1.54 g/p). Flowers and leaf dry weight had a significant and positive correlation with plant height, number of the main branches and lateral branches, leaf width, plant diameter, fresh weight, dry weight and essential oil yield. Cluster analysis grouped the 58 clones within two main groups. Factor analysis showed that three main factors justified 70.62 percent of the whole variation. Clones of Z28, Z19, K48, E7, H82, F14 and G48 were superior with regard to weight of dry leaves, flowers and essential oil yield. Discussion Superior S. rechingeri clones could be used for commercial cultivation in Dezful climate conditions. The most important biological production traits, yield of leaf and flower fraction, essential oil content and yield showed significant variation between clones. These variations could be used to breed high-quality and desirable cultivars for use in food and pharmaceutical industries.

Read More Background and Objectives Satureja khuzestanica and satureja rechingeri are two valuable and endemic medicinal species that grow widely in southwest parts of Iran. These species are rich in phenolic compound caracole; therefore, they have considerable biological activities. In order to evaluate the quantitative and qualitative yields of two savory species (Satureja khuzestanica and S. rechingeri) in different irrigation intervals, an experiment was carried out in the west of Lorestan (Kashkan) during the growing season of 2012-2013. Materials and methods The Experiment was conducted on the basis of split-plot design in completely randomized block design with three replicates. Irrigation treatments (15 and 30 days interval and rainfed) as the main-plot and species in two levels (Satureja khuzestanica and satureja rechingeri)as the sub-plot were carried out. The characteristics measured were leaf and flower yield, essential oil content, essential oil yield, essential oil compositions, leaf area index and plant height. Results Results showed that the effect of irrigation treatments on all traits except for essential oil compositions was significant. The effect of species on essential oil content and essential oil yield was significant. Mean comparison of traits showed that by increasing in irrigation intervals, leaf and flower yield, essential oil content, essential oil yield, leaf area index and plant height of both summer savory species were decreased amount of by 73, 23, 78, 80 and 33%, respectively compared to control (Irrigation interval of 15 days). Between species, essential oil content (3/7%) and essential oil yield (100/2 kg.ha-1) of rechingeri species were more than essential oil content (2/03%) and essential oil yield (62/2 kg.ha-1) of khuzestanica species. Discussion The leaf and flower yield, essential oil content, essential oil yield, leaf area index of both summer savory species were decreased by increasing irrigation intervals and rainfed cultivation. Trend of changes in essential oil yield was similar to leaf and flower yield, In other words, the essential oil yield was further affected by the herb yield (leaf and flower yield).
