A pot experiment was
conducted on Plumbago zeylanica
L. (Chitrak) under controlled water stress environment in greenhouse
during the kharif season. The experiment was laid out in completely
randomized design with five treatments of different water stress levels
i.e. control, 20%, 40%, 60% and 80% and four replications. Out of five
stress levels, 80% water stress has influenced root length, dry
herbage, plumbagin, potassium and proline content. In control
conditions the plant height, number of leaf, total leaf area, stomatal
conductance, transpiration rate, photosynthesis, CO2
utilization, H2O utilization and chlorophyll were found to
be maximum. The impact of water stress on plumbagin content has shown
increase trend with respect to different water stress levels that is
maximum at 80 % and minimum at control.
Key words: Plumbago zeylanica, water stress, plumbagin
