| Abstract/Contents: | "Field and laboratory studies with creeping bentgrass (Agrostis palustris `Penncross') grown in a sand/peat (4:1) medium recommended for putting greens showed that turf inoculated with the arbuscular mycorrhizal fungus Glomus intaradices was able to tolerate drought conditions significantly longer than non-mycorrhizal turf. Leaf water potentials remained higher in the mycorrhizal turf and declined at a slower rate than in the non-mycorrhizal turf. Mycorrhizal turf recovered more quickly from wilting than did non-mycorrhizal turf. Protection against drought was conferred by G. intraradices when turf was grown under conditions of low phosphorus fertilization (11 mg lā»Ā¹) but the benefits disappeared when the P concentration of the fertiliser was quadrupled to 44 mg lā»Ā¹. Of eighteen free amino acids and amides studied, Ī³-amino-n-butyric acid was the best indicator of water stress. The concentration of this amino acid increased significantly between days 3 and 4 of the drought in non-mycorrhizal turf and in mycorrhizal turf grown at 44 mg lā»Ā¹ P, but not in mycorrhizal turf grown at 11 mg lā»Ā¹ P. Mycorrhizal turf maintained significantly higher cholorophyll concentrations (avg. 29% more) than did non-mycorrhizal turf during the ten-day-long drought in the field." |
