Response of Reed Canary Grass <i>(Phalaroides arundinacea </i>(L.) Rausch) to Methylphosphonic Acid, an Organic Phosphorus Xenobiotic
The effect of methylphosphonic acid (MPA) on physiological and biochemical parameters of reed canary grass was studied. The treatment of the aboveground plant organs with 0.1 M MPA caused a stable oxidative stress in leaves, disturbed their pigment complex, and decreased the intensity of photosynthesis. The respiration rate increased. In distinction from leaves, roots were not strongly affected by MPA, and the MPA treatment had no significant effect on their growth, which indicated the successful adaptation of the rhizomatous grass to the xenobiotic.
