Abstract

Studying the INTERACTION between range plants increase our knowledge on the ecosystem functions. The balance between competition and facilitation was studied between a semi-shrub (Artemisia Khorassanica Podl.) and a perennial grass (Bromus kopetdaghensis Drobov.) in BAHARKISH RANGELANDs, Quchan, Iran. Sampling was carried out where both species were growing alone, or the perennial grass was growing under canopy of the perennial shrub. Measurements were conducted at the early growth, full vegetative or flowering stages of A. khorassanica. In the early growth season, higher SOIL MOISTURE, and lower MDA and H2O2 were found for the understory than open space, indicating facilitative effects of shrub on the grass. The reverse results were found during summer times, which were interpreted as competitive INTERACTION. The grass individuals also could affect SOIL MOISTURE and physiological performances of the nurse shrub, with their effect being negative during both early and late growth season. In conclusion, results of this experiment suggest a tradeoff in the positive (facilitation) and negative (competition) INTERACTIONs between A. khorassanica and B. kopetdaghensis. The type of relationship between the nurse shrub and its understory grass depends on the SOIL MOISTURE availability during different times of a growth season.
