The responses of photosynthetic gas exchange, chlorophyll fluorescence, content of pigments, main osmolytes, and malondialdehyde (MDA) to water-withholding for 15 days and re-hydration in seedlings of two mango cultivars (Mangifera indica L. var. ‘‘Choke Anand’ and var. ‘‘Khieo Sawoei’’) under 50% sunlight and full sunlight were investigated. For both cultivars, the waterwitholding resulted in progressively decreases in leaf relative water content, net photosynthesis (Pn), stomatal conductance (gs), and increases in the conversion of xanthophyll cycle pigments estimated by an index of leaf spectral reflectance (DPRI), carotenoid to chlorophyll ratio, non-photochemical quenching (NPQ), the contents of malondialdehyde (MDA) and compatible solutes (total soluble sugar and proline). The effect of the water stress was more pronounced in full sunlight than 50% sunlight. The maximum photochemistry efficiency measured at dawn was fairly constant during the period of the treatment for both cultivars under both light regimes. The water stress caused less pronounced inhibition of photosynthesis in ‘‘Choke Anand’’ than in ‘‘Khieo Sawoei’’ cultivar under both light regimes. After re-hydration, the recovery was relatively quicker in ‘‘Choke Anand’’ than in ‘‘Khieo Sawoei’’ cultivar. Both cultivars in both 50% and full sunlight showed complete recovery in photochemistry after 5 days of re-watering but photosynthesis did not show a complete recovery as indicated by gas exchange rates. As the results of lower NPQ, DPRI and osmotic adjustment in the cultivar ‘‘Khieo Sawoei’’ compared to the cultivar ‘‘Choke Anand’’, the former cultivar was less tolerant to drought than the latter. Our study further showed that partial shading (e.g., 50% of sunlight) significantly alleviated the harmful effect of drought stress on mango cultivars but in fact stomata of seedlings grown in partial shade was more responsive to water deficit than in full light.
