Abstract: 

In order to study the effects of Glomus hoi fungi, different levels of phosphorus and drought stress on some physiological characteristics of coriander (Coriandrum sativum L.), was conducted at Karaj Research Institute of Forest and Rangelands in 2006. Field experiment was carried out by a split factorial design with 4 replications. The factors were two level drought stress with irrigation after 30 mm water evaporation from evaporation pan (without stress conditions) and irrigation after 60 mm water evaporation (drought stress conditions) and also application and non-application of mycorrhiza, 0, 35 and 70 kgha-1 phosphorus fertilizer. The results showed drought stress has significant effect on water use efficiency, relative water content and proline accumulation rate (a=1%). Highest water use efficiency with 0.449 kgm-3 and proline accumulation rate with 6.767 mmol/ml were achieved under stress conditions and highest relative water content with %90.6 was achieved without stress conditions. Also, the results showed mycorrhiza and phosphorus had significant effects on water use efficiency (a=5%). Comparison of means showed that highest water use efficiency with 0.395 kgm-3 and 0.4 kgm-3 was achieved under application of mycorrhiza and application of 70 kgha-1 phosphorus, respectively. Relative water content and proline accumulation rate were not significantly affected due to phosphorus and mycorrhiza. The results showed that water use efficiency and proline accumulation rate were increased under drought stress conditions but relative water content decreased.
