干旱

0Using experimental materials of one-year old steckling from six hybrid tulip clones (NE04, NE22, NE23, NE25, NE38, NE78), the relative water content, permeability of plasma membrane, soluble protein and proline contents, activity of superoxide dismutase, and ascorbate peroxidase were analyzed under drought stress.
