EFFECT OF ABSCISIC ACID ON DROUGHT TOLERANCE OFSELECTED PLANT SPECIESA. Suvarna Latha, K.S. Shanthi Sree and P. SujathammaAbstract Abscisic acid is a phytohormone produced by plants and has various roles in plants growth and development.ABA function in plants is still not well understood, despite of its involvement in abscission. However, ABAhas a critical role in reducing a variety of stress reactions. Drought stress is one of the abiotic stress and isdefined as a prolonged period of reduced water supply. ABA controls plants response to various conditionssuch as salinity, low temperature, and drought. It plays a vital role in regulating a variety of processesinvolved in plant growth, such as floral induction, seed dormancy, embryo maturation, seed germinationand root growth. The present research work is S carried out to analyse the drought tolerance and leaf Chlorosis by the application of ABA on selected three medicinal plant species Talinum paniculatum, Bryophyllumpinnatum and Sauropusandrogynus. |
