Other claims from this paper (6)
- Mechanism Up to 80% of the UV-induced specific leaf weight change in cucumber leaf 1 was attributed to carbohydrate accumulation.
- Observation Starch rose from 13 to 23% of cucumber leaf 1 dry weight under UV.
- Observation Cucumber leaf 3 had less than 8% nonstructural carbohydrates.
- Observation The UV effect on specific leaf weight was smaller in cucumber leaf 3.
- Mechanism The authors interpret the data as photosynthate accumulating in leaf 1 after UV-B inhibited leaf 3 growth.
- Recommendation Increased specific leaf weight need not indicate increased leaf thickness.
