Thymuskotschyanus Boiss. & Hohen. is a perennial medicinal shrub growing wild in some regions of Iran including Yazd province. This research was carried out in order to analyze oil quantity and quality of cultivated Thymuskotschyanus in the Medicinal Plants Farm, Yazd, Iran. The seeds of 19 accessions collected from natural habitats were sown in a greenhouse and the seedlings were planted in the farm. Shoots were harvested at 50% flowering stage in the second year and dried under shadow. Essential oil was extracted with water distillation method and oil components were identified after determining oil content. The highest amounts of oil content respectively were related to accessions TK7 (3.42%), TK12 (3.22%), TK17 (2.66%) and the lowest amount was observed in accession TK6 (0.79%). The highest amounts of oil production respectively were recorded in accessions TK5 (38.3kg/ha), TK7 (36.4kg/ha) and TK12 (36.1 kg/ha) and the lowest amount was related to TK1 (1.3 kg/ha). Cluster analysis based on eleven oil components classified the accessions into three groups. The first group, (TK2, TK6, TK13, TK18, TK16, TK19), was rich for thymol-p-cymene, the scond group (TK1, TK3, TK4, TK5, TK7, TK11, TK14, TK15, TK17) for carvacrol-thymol and the 3rd group (TK8, TK9, TK10, TK12) was rich for Geraniol-linalool. In general, accessions TK7, with 3.42% oil content, 36.4 kg/ha oil production and 63.8% carvacrol; TK14, with 2.2% oil content 35.5 kg/ha oil production and 47.2% carvacrol and thymol, TK5 with 2.4% oil content, 38.3 kg/ha oil production and 57% thymol and carvacrol are proposed as superior accessions.

Satureja belongs to lamiaceae with different species throughout the world. Annual and perennial species of this medicinal plant grow naturally in Iran, of which nine species are endemic. In this research, perennial species of Iranian savory were evaluated during 2009-2013, Yazd, Iran. Accessions of different species were cultivated at Research Station of Medicinal Plants using a randomized complete block design. Different traits including percentage of plant establishment, plant height, plant canopy diameter, shoot fresh yield, shoot dry yield and oil content were measured. Variance analysis showed significant differences (p<0.01) among accessions for plant establishment, plant canopy diameter, plant height, essential oil percentage, shoot dry yield and leaf dry yield . Based on mean comparisons, SKM (Satureja bachtiarica) from Yazd, 107 (S. spicigera) from Gilan, 15 (S. rechingeri) from Ilam, 123-1 and 123-2 (S. mutica) from Khorasan province were superior accessions for valuable agronomic traits such as percentage of establishment, shoot yield and oil content.

The Thymus genus, belonging to Lamiaceae family, consists of over 215 different species in the world. Eighteen species are growing naturally in Iran, among which four species are endemic. Different species of thyme are used in the food, pharmaceutical and cosmetics industries. This research, conducted in Yazd province during 2008-2011, was aimed to investigate the phenology and compatibility of different thyme species. The seeds of 69 accessions of unknown thyme species, provided by the natural resources gene bank of Iran, were planted to study the phenology and establishment rate. According to the obtained results, among 69 accessions studied, eight accessions were compatible with the climate conditions of the study station, 28 accessions were fairly compatible, and 33 accessions were less compatible. The average of establishment rate was calculated to be 75%, 68% and 58% in 2009, 2010 and 2011, respectively. The highest establishment rate (100%) was related to accession BHUXD )T. fedchenkoi×T. pubescens(, selected as superior accession, and the lowest establishment rate (7%) was related to accession XDRNJI (T. lancifolius×T. pubescens).

For assigning of drought stress and glycine betaine effects on yield, yield components and essential oil in German chamomile (Matricaria chamomilla L.) genotypes,a field experiment was conducted in the Field of the Agricultural Educational Center of Yazd in 2008-2009 Cropping season. The experiment was established as a randomized complete blocks design using a split plot factorial with 4 replication arrangement and three factors including drought stress at three levels (irrigation at 60, 120, 180 mm evaporation pan class A) in main plots and factorial combination of Glycine betaine (no foliar application, 2, 4 kg/ha foliar application) and cultivars (Isfahan mass and Hungary breed seed) in subplot. Plant height, plant flower number, dry flower yield and relative water content were measured. Results showed there are indirect relations between drought stresses and plant height, plant flower number, dry flower yield and relative water content. Also results showed that 2 kg/ha foliar application of Glycine betaine was better than others and there are no significant different between cultivars.
