Phytotoxicity and Benzoxazinone Concentration in Field Grown Cereal Rye (Secale cereale L.)

Figure 6

Variation of total benzoxazinone content (sum of DIBOA-glucoside, DIBOA, and BOA) in shoot tissue of three rye cultivars between dates 61 and 90 (Julian dates) of the second year of experiments. Values associated with the same letter are not significantly different according to the Tukey-Kramer method (). Vertical bars represent standard errors at each sampling date.
