Other claims from this paper (9)
- Intervention effect Microelement shortage significantly decreased photosynthetic pigment contents in both lettuce cultivars.
- Intervention effect Micronutrient deficiency decreased maximal quantum yield of PSII photochemistry and performance index in lettuce.
- Intervention effect Micronutrient deficiency increased relative variable fluorescence at J-step and minimal fluorescence yield of the dark-adapted state in both lettuce cultivars.
- Intervention effect Micronutrient deficiency enhanced osmoregulators such as proline, soluble sugar and total phenols in lettuce.
- Intervention effect Fe, Zn and Mn deficiency led to a lesser production of dry mass in lettuce.
- Intervention effect Fe deficiency was more destructive to PSII efficiency than Zn and Mn deficiency in both lettuce cultivars.
- Intervention effect Under micronutrient deficiency, leaf lettuce was more tolerant to stress conditions than crisphead lettuce.
- Intervention effect Under micronutrient deficiency, leaf lettuce had higher efficiency of PSII, electron transport and quantum yield than crisphead lettuce.
- Intervention effect Under micronutrient deficiency, leaf lettuce had higher specific energy fluxes and osmoregulators than crisphead lettuce.
