Fig. 5.

The effect of BSO on the accumulation of GSH and fresh weight of metallicolous (M) and nonmetallicolous (NM) plants of D. carthusianorum cultivated for 14 days in the control conditions (0 μM Cd). Data represent relative values calculated from the means of absolute values. The absolute values for GSH accumulation and for FW were analyzed statistically, and p values of Kruskal-Wallis analyses are given. The values followed by the same letters (upper case letters for M ecotype and lower case letters for NM ecotype) are not significantly different at p < 0.05
