UV-B and PAR in single and mixed canopies grown under different UV-B exclusions in the field, single versus mixed canopies) or to UV-B effects on plant morphology, lead to differences in UV-B and UV-B/PAR doses within canopies..The development of a very small (10 mm diameter) UV-B and PAR sensor on a long 5 mm wide stick allowed us to measure the penetration of UV-B and PAR in single and m织布机 发表于 2025-4-1 06:30:18
The response of , to enhanced UV-B radiation under low and near ambient PAR levelsason, we studied effects of enhanced UV-B (12 kJ m. d.) at low and near ambient PAR levels on young vegetative plants of ., in the greenhouse. It was hypothesized that near ambient PAR levels could reduce the negative UV-B effects on growth, due to higher amounts of UV-B absorbing compounds in the l投射 发表于 2025-4-1 13:23:56
