plots showed smaller decreases with the exception Qf Atrazine, which gave ,an early decrease of 95 per cent with 'no cultivation. While the difference. 'between the cultivated and uncultivated t.ttazine treatments were never significant. the' undisturbed .od treated with Atrazine consi.tently Jave carbohydrate yield. equal to or greater than when Atrazine w~. supplemented by tillage. The effect of Atrazine alone increased from a .evere fructo.e yield reduction of 95 per cent by the fir.t .ampling date to Virtually 100 per cent by late fall. This continued to the follow1ng spring. "ibdicating that no live rhizomes remained. Simazine. without cUltivati~(.~resulted in an e.arly reduction of 76.~er cent in the fructose yield. WhlCh iacre.sed to 97 per ce~t by late fall. By ~he following .pring, however. the affect of Simazine decreased to a 73 per ce~t reduction in fructose yield. Whllespring plowingt'ended to slightly augment the effectof Simazine ontht(ltotal food reserves throliShout the experiment, it, also decreased from a 99 per" cElnt,depletionln late SU1lllll8t' to 87 per cent by the following spring. indicating,thatat least some live rhizomes survived. Similar trends. but wi~h les. striking reductions, were generally oD.erved for the other three herbiCides. 'In all cases, Amitrol-T. Fenac and Dalapon on uncultivated plots induced a, reduct,ion in underground carbohydrates which increased to a high of 83 per cent, SOper cent and ,75 per cent. respectively. by fall. The effecta of these herbicides ceased or d~lnished during the following winter and spring, however. show1ng a reductio~ of 7lper cent for Amitro17T, but increases.of 1 .per cent for FeMcand 42 per cent fot: Dalapon. While the .ingle spring plOWing after application of Amitrol-T,Fenae'or Dalapon was yery effective in stimulating or prolonging the rhizome and carbOhydrate yield reductions. their effects ware,nevertheless, diminished between latef.ll and spring. There was generally a clos. relationship ~e~e.nthe appearance of the quackgrass rhizomes and the level of food reserves they contained. Vlgoroua white rhizomes with many fibrous roots were always relatively high in carbohydrates. As the prevalence of roots decreased. the, rhizomes Fadually appeared more diacolored, and their carbohydrate level generally dtminished accordingly. When no fibrous roots remained on the IIh.izomejoints. the rhizomes appeared 1n ,various shades of brown corresponding to the degree of deccDposition and carbohydrate depletion. 297 There was a general relationship between the elfects of cultural and chemical treatments on tlle Eurv~val ar-d regrowth of rhizomes and their effects on the carbohydrate content, of rhizollles' ... presented in a pi'evioull paper (2). Of the cultural tr2atments. spring plClwingresulted'ln the most rapid decrease in yield cf t'oth rhizomes and carbohyl1I8tes; As soon as new topgrowtb developed. however. c&rbohydrates were gradually restored and the growth of new rhizomes was stimulated. Repeated cultivations during the growing seasou'resulted in a continuous depletion of rhizomes and carbohydrates. Although more than 25 per cent of the total dry weight of rhizomes still remained in the fall and the following spring. they Were greatly weakened due to a allllUltaneous reduction in food reserves,.
