Fig. 6. Effect of October defoliation on starch (A) and soluble sugar (B) concentrations in alfalfa taproots. One half of plants in each plot were defoliated in October. Roots were sampled in October at the time of defoliation, and in December. Included in the study were the dormant cultivars ‘53Q60’ (Q60) and ‘54H69’ (H69), the nondormant cultivar ‘5939’, and three semidormant germplasms: 96P51PSI (P51), Z57NO2 (NO2), and 96P55PSI (P55). Error bars represent one standard error of the mean (n = 7). Exp. 2.
