Morph-physiological responses of two switchgrass (Panicum virgatum L.) cultivars to cadmium stress

Morph-physiological responses of two switchgrass (Panicum virgatum L.) cultivars to cadmium stress

Two cultivars of switchgrass, ‘Alamo’ (lowland type) and ‘Cave‐in‐Rock’ (upland type), were used to examine the morph‐physiological responses of plants to different cadmium (Cd) levels under hydroponic condition treated with 0, 10, 20 and 40 μmol L−1 CdCl2 for 2 weeks. The main results showed that b...

Zusammenfassung:Two cultivars of switchgrass, ‘Alamo’ (lowland type) and ‘Cave‐in‐Rock’ (upland type), were used to examine the morph‐physiological responses of plants to different cadmium (Cd) levels under hydroponic condition treated with 0, 10, 20 and 40 μmol L−1 CdCl2 for 2 weeks. The main results showed that both seedlings of ‘Alamo’ and ‘Cave‐in‐Rock’ can survive even in 40 μmol L−1 CdCl2 treatment. However, the growth of the two cultivars was significantly (at least P
