Determination of medicinal plants growth under different water stresses could be well guidance for cultivation of resistant plants in dry regions. In numerous glasshouse experiments under Completely Randomized Design (CRD), 5 medicinal plants species planted separately. Plantago psyllium, Achillea millefolium, Salvia officinalis, Calendula officinalis and Matricaria chamomilla were treated by well water (FC), 75%FC, 50%FC and 25%FC. Total dry matter, root weight, root length, shoot weight and height of medicinal plants were measured and analyzed separately. All of water and water stresses treatments were significant different in 1% probability. Among the medicinal plants in this experiment, Salvia officinalis and Achillea millefolium had the best growth in all water stresses treatments and conserved their freshness under sever water stress. These species could establish as the resistant medicinal plants in dry region or water deficit. Other species also completed their life cycle under sever water stress.

Because of the importance of water stress influence on plant growth, metabolism and yield, Satureja hortensis L. was imposed towater stress treaments. Irrigation treatments were selected basis on the different percentage of field capacity (FC), including (i) a control which was irrigated to full field capacity during the growing season (FC), (ii) two moderate water stress treatments during vegetative (LS1) and flowering stages(LS2)and (iii) severe water stress treatments during flowering stages(HS). Results showed that plant water potential reduced from -0.5 to 1.5 Mpa and RWC (relative water content) decreased too. Also water stress induced high amount of proline. The amount of proline was the highest in sever treatment while it changed from 0.69 to 7.36 μ M/g FW in FC, LS2 treatments.

The majority of the crop seeds have physiological dormancy after harvesting. This phenomenon is depending to different physiological dormancy. This phenomenon can overcome by pre-treatment including prechilling, pre-heating, dry storage condition, using chemical for promoting germination and overcoming of inhibitor substances. In this study the seeds of two medicinal species (Eruca sativa Lam. and Anthemis altissima L.) under two cold room (4°C) and dry storage (room temperature) conditions were maintained over six months and tested by standard germination test. The physiological quality of the seed rocket plant had not any significance differences in two conditions. The reason might be due to non-physiological dormancy of the seed species. Whereas, percent of germination in the species of chamomile was significant in the two conditions. As it is clear the percent of germination of the chamomile from dry storage condition was higher from cold room condition and this due to physiological dormancy of plant seed which overcome by dry storage condition. The speed and vigor index of plant seed had no significant differences in two conditions.

The medicinal plant Datura stramonium (D.s) is a rich source of alkaloids which has been introduced as an analgesic herb. Regarding the possible interaction between opioid and muscarinic systems and the key role of opioid receptors in alleviation of pain, we investigated the effect of alcoholic Datura seed extract in acute and chronic pain. In the present study in order to producing acute and chronic pain, hot plate and formalin tests were used. In treatment group 20 min prior to pain scoring the extract was intraperitonealy administered to the animals and the results was compaired with the control group. In our experiments, the extract alleviated the pain dose dependently, and ED50 was equal to 25 and 50 mg/kg in hot plate and formalin tests, respectively. Analysis of the data by student t-test have shown that the acute and chronic pain producing by formalin and hot plate tests were significantly attenuated in animals which treated with DS seed extract. In order to determine the LD50, doses of 500-4000 mg/kg i.p. of the extract were applied to the animals. In this experiment the calculated LD50 was 2500 mg/kg. In addition, our results show that the DS seed extract has an analgesic effect in both acute and chronic pain which was produced by hot plate and formalin tests. It is likely that, this effect can be attributed to the D.s extract alkaloids which interacted with opioid system. Also, regarding the significant difference between ED50 and LD50, perhaps we can introduce the D.s seed extract as an analgesic medicinal plant.

Rosa damascena from eight rejions in western parts of Iran, were cultivated at the experimental field of Research Institute of Forests and Rangelands, using three replicated randomized complete blocks design. Six genotypes were compared based on different traits including flower yield in 2003 and 2004.The obtained data was performed using ANOVA, (wich mean classification and correlation analyses). Genotypes showed significant differences in terms of the measured traits. Comparison in meaning, classified the genotypes in 4, 2, 3 and 4 groups, based on flower yield, flower weight, dry matter percentage and petal weight to flower weight ratio, respectively in 2003 and in 4, 2, 2 and 5 groups in 2004. It could be concluded from the results of different analyses that although the genotypes could be grouped based on geographical origins, flower yield, flower number and dry matter percentage could be used as appropriate selection factors for classification of damask rose genotypes in western parts of Iran.

In order to effects of reduction in nitrogen fertilizer in agroecosystem, a field experiment was carried out on Mellisa officinlais in Alborz research complex in 2004 year. The treatments was 80 kgha-1 nitrogen application in soil and %2 spry application that was compared to the control treatment (no fertilizers) in complete randomize block design with three replication. In both treatments, the first application was conducted when plant high was 10 cm and second application was after 30 days. The harvest carried out before flowering. The results showed that, in comparison of other treatments, the application of nitrogen in form of spry , raised dry mater yield to 5532.8 kgha-1. The LSD test showed that, the spry method was significant (a=%5) to control. In the spry method, nitrogen fertilizer reduced 87.5% to the control. Based on the results, low input Agriculture systems could be introduced for sustainable agriculture.
