ABSTRACT
Desiccation tolerance (DT) withstands extreme dehydration (90-95% water loss). Post-gemination DT is one of three types of DT known to be present in angiosperms. Wheat possesses post-germination DT. Present study found post-germination DT superior in drought tolerant cultivar than drought susceptible cultivar. Further investigation demonstrated that grades of phenolics, lignin, anthocyanins, gamma-amino butyric acid (GABA), proline, sugars and starch and activities of guaiacol peroxidase, glutathione peroxidase, sucrose phosphate synthase, sucrose synthase, and amylases were linked to the post-germination-DT of drought tolerant compared to drought susceptible cultivar. Results concluded that post-germination DT can be the marker of drought tolerance in wheat. Antioxidants, proline, sugars, and GABA may be the chief players involved in post-germination DT in wheat.
