Abstract

Abstract Norflurazon (0, 0.2, 0.4, 0.83, 1.65, or 3.3 μ M incorporated into sand inhibited carotenogenesis in wheat ( Triticum aestivum L. cv Holley). EPTC (0, 0.16, 0.33, 0.66, or 1.32 μ M) was applied concomitantly. EPTC (0.66 and 1.33 μ M) induced a partial reverse of the norflurazon inhibition of carotenogenesis. This reversal was postulated as due to an increased concentration of available geranylgeranyl pyrophosphate for phytoene synthesis and to an increased synthesis of carotene, chlorophyll a (Chl a), and chlorophyll b (Chl b) in EPTC-treated wheat. The increased pigment content partially offset photooxidation of carotenoids, Chl a, and Chl b at high light intensities. Utilization of these factors may result in protection of crops grown in soils bearing norflurazon residues.
