Abstract
The most crucial element in the area where
abiotic stress is prevalent is irrigation. To assess the effects of various
levels of stress on the development and bioactive components of A.
paniculata, a pot experiment with five stress treatments and three
replications was carried out. Results demonstrated the statistical significance
of water stress on plant growth metrics. Finding showed that reducing
irrigation supply to 50% (T3), deficit irrigation has significant effect on
A. paniculata's fresh weight, dry weight, leaf to stem ratio, leaf length
and width all increased by 28.29%, 45.3%, 28.45 %, 27.59% and 19.54 %,
respectively when compared to those of the control (T1) experiment. With just a
slight drop in growth metrics (plant height, fresh and dry weight, etc.),
chlorophyll content, and relative water content of leaves, rainfed irrigation
had a substantial impact on plant survival. The plant in treatment T5 underwent
extreme drought stress conditions, and the highest decrease was seen there. In
contrast to the chlorophyll content and RWC, which have fallen as the shortage
of water has become worse, root length and root to shoot ratio has grown
massively as stress levels go up with the highest increase in rainfed
irrigation (41.97 %). Maximum accumulation of active component andrographolide
(2.46%) was found in treatment T2 (Daily irrigation) with minor
decrease in Neo-andrographolide (0.19%) and
14-deoxy-11,12-didehydroandrographolide (0.16%) as compared to control.
According to the findings, A. paniculata may be grown in arid and semiarid
regions as an alternative crop resistant to stress. In regions where water
supply is very limited and irrigation management is subpar, deficit irrigation
(T3) may be a viable water saving strategy. This approach can help cut the
overall cost of irrigation.
