Fig. 7. Effect of October defoliation on (A) sucrose, (B) raffinose, and (C) stachyose concentrations in alfalfa taproots sampled in December. One half of plants in each plot were defoliated in October. 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.
