Abstract

Drought preCONDITIONING (DP) is a method of irrigation with low frequency and longer duration to extend the root system and suppress drought damage in plants. In the present study, the effect of DP for 30 days on increasing tolerance to drought stress in two turfgrass species, creeping bent grass (Agrostis stolonifera cv. Palustris) and tall fescue (Festuca arundinacea cv. Greystone) was investigated. DP and control plants were irrigated for 50 days with different levels of soil suction (20-23, 40-43, 50-53 and 70-73 centibar), and finally plants were watered up to field capacity level for 15 days, to recover from stress. Results showed that DP significantly lead to reduction in shoot length and increase in root length in both turf grass species. DP plants showed less wshoot dry and fresh weight and also less ELECTROLYTE LEAKAGE (EL) at each levels of stress, in compare with the control. Furthermore, DP plants showed greater reduction in EL after RECOVERY. DP treatment also reduced leaf RWC at the end of 50 days of stress and after RECOVERY in tall fescue, but in creeping bent grass retained it at the control level. Overall, it appears that DP treatment can increase tolerance to drought stress in two species with increasing root length, reducing shoot length and EL and preserving leaf RWC.
