Abstract :
The improvement of vegetation due to full or partial protection was depicted by most of rangeland scientists. This study investigated the effect of livestock grazing on percentage of germination ( PG ), mean growth time (MG) and germination rate ( GR) of the even-aged Atriplex canescens , by comparing two sites across zarand, shahreiar rangelands located in the southwest of Tehran, Iran. For this purpose, the seeds of 30 A. canescens within each of the two study sites were collected and a quantitative analysis of the seeds was carried out by laboratory analysis. The results indicated that, grazing had no significant influence on PG, MGT and GR
