Responses of Green Leaves and Green Pseudobulbs of CAM Orchid Cattleya laeliocattleya Aloha Case to Drought Stress
Figure 2
Diurnal changes of Chl fluorescence ratio after CAM orchid Cattleya laeliocattleya Aloha Case plants were subjected to drought stress for 1, 2, 3, and 4 weeks. Means of 8 measurements from 8 different plants. Vertical bars represent standard errors. When the standard error bars cannot be seen, they are smaller than the symbols. **Above the means of GL and GPSB of well watered plants are statistically different from the drought-stressed plants ().
