Abstract
Cymbidium sinense was able to withstand severe drought. Drought resistance was managed through a variety of morphological and physiological adaptations. The plant possesses a fleshy root with velamen, a water-storing pseudobulb and special stomatal morphology. Even after 42 days of drought, when the soil water content had been reduced to 15% of maximum holding capacity, the water content in leaf, roots and pseudobulbs was 63-70%. Stomatal closure was observed when the leaf water potential was around — 1.05 M Pa. The plants were able to recover following watering after being subjected to drought for 42 days.
