Other claims from this paper (18)
- Intervention effect UV-B radiation reduced leaf, stem and root fresh weights of Cynoglossum officinale seedlings.
- Intervention effect UV-B radiation reduced leaf area and the leaf:shoot ratio of C. officinale seedlings.
- Intervention effect UV-B radiation increased shoot dry matter content, specific leaf weight and leaf greenness of C. officinale seedlings.
- Intervention effect UV-B radiation decreased leaf, stem and root fresh weight of Centaurea diffusa seedlings.
- Intervention effect UV-B radiation decreased leaf area of C. diffusa seedlings.
- Intervention effect Shoot dry matter content, specific leaf weight and leaf:shoot ratio of C. diffusa seedlings were unaffected by UV-B radiation.
- Intervention effect Leaf greenness of C. diffusa seedlings was unaffected by UV-B radiation.
- Intervention effect UV-B exposure caused no change in leaf or stem fresh weight of T. pratensis seedlings.
- Intervention effect UV-B exposure caused no change in leaf area or leaf:shoot ratio of T. pratensis seedlings.
- Intervention effect Uniseriate trichome abundance in C. officinale seedlings increased in response to UV-B exposure.
- Intervention effect Trichome orientation in C. officinale seedlings changed in response to UV-B exposure.
- Intervention effect UV-B treatments decreased uniseriate trichome abundance in C. diffusa.
- Intervention effect Glandular trichome abundance and the ratio of glandular to uniseriate trichomes in C. diffusa were not affected by UV-B treatments.
- Intervention effect T. pratensis seedlings showed no change in the amount of epicuticular wax on the adaxial leaf surface in response to UV-B irradiation.
- Intervention effect Shoot dry weight of T. pratensis seedlings was not influenced by removal of epicuticular wax before UV-B exposure.
- Mechanism The authors suggest that epicuticular wax is not an important factor in acclimation of T. pratensis seedlings to UV-B radiation.
- Observation Susceptibility to UV-B-induced damage was greatest for C. officinale seedlings.
- Observation Susceptibility to UV-B-induced damage was least for T. pratensis seedlings.
