Title

INVESTIGATION OF THE MORPHOLOGIC - PHYSIOLOGIC CHANGES OF PUCCINELIA DISTANCE AND AELUROPUS LITTORALIS TO SALINITY AND DROUGHT RESISTANCE

Pages

  1-10

Abstract

 Determination of plant RESISTANCE TO DROUGHT and SALINITY is very important for selecting the favorable plant species in rangelands. The aim of this study was to compare the SALINITY and drought tolerance of the two rangeland species namely puccinelia distance and Aeluropus Littoralis. In this study biomass production of these two species was also compared. The Experimental design of split-split plot in randomized block was excuted for the study. The main plots were allocated to the TREATMENTs of 7 and 14 days irrigation periods. The subplot were 4 level of SALINITY including 100, 150, 200 mmolar Cl.Na and normal irrigation water as control respectively. The morphological criterias such as WATER POTENTIAL, wilting percentage of the plants and also dry biomass were evaluated in this study. In the context of plant anatomy, The density of stomata per unit area of leaves, vesicular structure, mesophyt tissues and epidermis were also investigated. The results showed that wilting percentage increased with increasing SALINITY and water deficit (drought). With increasing the time of drought and SALINITY stress, the weight of dry stem and total dry mass were decreased. The wilting percentage and reduction of total dry biomass in Aeluropus Littoralis was more than puccinelia distance. It was concluded that puccinelia distance is more resistante compare to Aeluropus Littoralis while Aeluropus Littoralis is more tolerate to SALINITY stress.
