| 英文摘要 | [Objective] This study was to determine the response of Ficus microcarpa L. foliage to polyethylene glycol (PEG) simulated water stress using chlorophyll fluo-rescence imaging technique. [Method] The responses of detached leaves from Ficus microcarpa, Ficus benjamina and Nerium oleander to PEG-6000 simulated waterstress were detected, and the chlorophyll fluorescence imaging technique was usedto detect and analyze the stress at different spots of a single leaf simultaneously. [Result] The responses of Ficus microcarpa, Ficus benjamina and Nerium oleander todehydration showed that: ① the maximal photochemical efficiency (Fv/Fm) and non-photo-chemical quenching (NPQ) values were small in the reaction center among different detected spots of leaves, and there were great differences between relativeelectron transport rate (ETR), photochemical quenching (qP) and quantum efficiencyof PSII photochemistry ( Φ PSII ); ② the differences of these parameters were more ob- vious among different spots of water-stressed leaves; ③ the discrete degrees of thespecies with strong resitances decreased significantly. [Conclusion] This study laysthe foundation for the further research on the response of plants to drought stress using chlorophyll fluorescence imaging technique. |
