“…Inhibition of leaf CER has been observed in small grains (Birecka and Dakic-Wlodkowska, 1963;King et al, 1967), vegetables (Claussen and Biller, 1977;Hall and Milthorpe, 1978), root crops, (Burt, 1964;Nosberger and Humphries, 1965), legumes (Crookston et al, 1974;Mondai et al, 1978), and maize (Kiesselbach, 1948;Moss, 1962). The observed decline in CER may occur from 24 hours to 40 days after sink removal, depending upon the species and method of treatment.…”
