The mechanisms of a plant to resist water stress can be divided into 2 components: avoidance and tolerance. However, reliable methods for measuring these components have not been established. We qualitatively evaluated the avoidance and tolerance abilities of shoots in diploid and tetraploid populations of perennial ryegrass (Lolium perenne L.) by continuously measuring their water contents and mortality rates under severe dehydration stress. Plant age greatly influenced dehydration resistance… CONTINUE READING
