From: Bio-refining of perennial ryegrass (Lolium perenne): evaluation of aqueous extracts for plant defence elicitor activity using French bean cell suspension cultures

Fig. 1

Elicitation of bean cell suspension cultures with aqueous extracts from four L. perenne varieties, assessed 24 h after treatment, showing tissue browning score (a), fresh weight of cells (b) and culture medium absorbance at 280 nm (c). Suspensions were treated with either 3.3 ml/l supernatant (open columns) or re-suspended pellet (shaded columns) or 33 ml/l supernatant (filled columns) or re-suspended pellet (hatched columns). Control cells treated with water gave a score of zero on the tissue browning scale. Bars indicate ± the LSD at P ≤ 0.05 (residual d.f. = 60)
