Drought stress is one of the foremost abiotic
stresses which causes damage to verbena plant production by affecting its growth
and development. There is less information available regarding utilization of
perennial verbena under drought conditions. To check the ability of perennial
verbena plant under water deficit conditions a pot research trial was planned.
Perennial verbena¡¯s seeds were sown in plastic trays and applied water daily.
When seedlings attained two to three leaves stage then transplanted them into
pots and exposed to different intervals of drought. Five drought intervals were
applied such as after one day (T0), 4
days (T1), 6 days (T2), 8 days (T3) and 10 days (T4) irrigation intervals. Pots
were arranged by adopting completely randomized design with four replications.
Many morphological i.e. plant height
(cm), root length (cm), number of leaves and flowers/plant, fresh weight of shoot and root (g), dry
weight of shoot and root (g) and chemical attributes i.e. chlorophyll ¡°a¡±, ¡°b¡± and total contents of chlorophyll were examined
during this study. The findings exhibited that perennial verbena plant
performed best under control conditions while when we increased drought
interval gradually from 4 days¡¯ interval till 10 days¡¯ interval it affected all
growth and chemical attributes badly and caused severe damage at 10 days¡¯
interval.
