| Abstract/Contents: | "Bromacil (5-bromo-3-sec-butyl-6-methyluracil) had no effect on germination but reduced growth of emerging shoots of orchardgrass (Dactylis glomerata L. 'Virginia Common') more than Kentucky bluegrass (Poa pratensis L. 'Merion'). Fresh weight gain and transpiration were reduced in orchardgrass seedlings at 0.125 ppmw of bromacil whereas 1.0 ppmw were required for reductions in bluegrass. Photosynthesis was inhibited in both plants; however, bluegrass recovered in 6 days. Water soluble carbohydrate content was greater and was not reduced as much by bromacil in bluegrass compared with orchardgrass. Absorption of 2-14C-bromacil from solution and translocation to shoots was directly related to transpiration rate. Bromacil was translocated acropetally from sheath and foliar treatments. Higher metabolic conversion of 2-14C-bromacil occurred in bluegrass compared to orchardgrass. Metabolites detected in plant extracts were 5-bromo-3-(2-hydroxy-1-methylpropyl)-6-methyluracil and an unknown. Traces of 3-sec-butyl-6-methyluracil and 5-bromo-3-sec-butyl-6-hydroxymethyluracil were also detected. Bluegrass tolerance involved high carbohydrate levels in tissues, hydroxylation of bromacil, and recovery of photosynthesis." |
