| Abstract/Contents: | "Several modified gibberellins which inhibit shoot elongation have been assessed as turfgrass growth retardants. Dichloro-methano 16,17-dihydro GA₅ (DMDGA₅) effectively inhibited growth of the cool season grasses, Festuca arundinacea Schreb., Poa pratensis L., and Lolium perenne L. Turf growth (weekly cutting dry weight) was reduced by up to 70% in three separate field trials over three seasons. This inhibition lasted up to 5 wk before recovery to control growth rates and, often, there was then a transient enhancement of growth. DMDGA₅ inhibited turf growth to the same extent as did the commercial turfgrass retardant, Trinexapac-ethyl (commercially formulated as Primo, Novartis, Inc., Basel, Switzerland). Daily water use was also 25 to 30% less over at least 4 wk in studies with mini-swards growing in controlled environment conditions. With isolated plants of two cultivars of P. pratensis (cvs Holt and Bronco) grown in controlled conditions leaf elongation rates were more than three-fold greater in long than short daylengths. Both Trinexapac-ethyl and DMDGA₅ blocked most of this growth increase as did a related derivative, 16,17-dihydro GA₅. Since these compounds inhibit gibberellin biosynthesis it appears that the extra growth in long days arises from an increase in gibberellin context." |
