Other claims from this paper (11)
- Intervention effect UV-B increased phenylalanine ammonialyase activity by 27 to 78%.
- Intervention effect UV-B increased total polyamines.
- Intervention effect Catalase and superoxide dismutase activities varied greatly in response to UV-B.
- Association There were no interactive effects of UV-B and PAR source on PAL or catalase activity or total polyamines.
- Association UV × PAR source interaction affected superoxide dismutase activity.
- Intervention effect UV-B increased chlorosis of cucumber seedlings.
- Intervention effect Stem elongation, biomass production and leaf enlargement were greater under HPS/DX lamps than under MH lamps.
- Intervention effect Chlorosis was greater under HPS/DX lamps than under MH lamps.
- Association Chlorosis was greater in Poinsett than in Ashley.
- Association Chlorosis was greater in lower leaves than in upper leaves.
- Association Apart from chlorosis, UV-B, PAR source and cultivar had no interactive effects on the growth parameters measured.
