Other claims from this paper (17)
- Observation Antioxidative enzyme activities were greater in Cattleya than Cymbidium.
- Observation In Cattleya, enzyme activities rose slightly during daytime.
- Observation In Cymbidium, enzyme activities rose at the start of night.
- Intervention effect Full sunlight reduced SOD activity in Cattleya leaves.
- Intervention effect Full sunlight greatly enhanced CAT activity in Cattleya leaves.
- Intervention effect Full sunlight slightly promoted APX activity in Cattleya leaves.
- Intervention effect Full sunlight decreased SOD and CAT activities in Cymbidium leaves.
- Intervention effect Full sunlight slightly decreased APX activity in Cymbidium leaves.
- Intervention effect High radiant flux significantly decreased SOD and CAT activities in Cattleya leaves relative to control after one month.
- Observation Cattleya CAT activity recovered slightly during further cultivation.
- Intervention effect Low radiant flux increased and sustained APX and CAT activities in Cattleya and Cymbidium leaves.
- Association Foliar chlorophyll contents declined as radiant flux increased in both orchid hybrids.
- Association Foliar chlorophyll contents were positively correlated with the three enzyme activities.
- Intervention effect High radiant flux initially lowered the chlorophyll a to b ratio and beta-carotene content in Cattleya, which recovered by three months.
- Intervention effect High radiant flux slightly decreased chlorophyll a to b ratio and beta-carotene content in Cymbidium leaves.
- Intervention effect Low radiant flux greatly increased chlorophyll and beta-carotene contents in Cymbidium.
- Observation Cattleya was interpreted as better adapted to high radiant flux than Cymbidium.
