| Abstract |
ABSTRACT: Drought stress is a major factor limiting rice growth and causes changes in metabolic processes. This
research aimed to study effects of seed priming with various chemicals including distilled water (hydropriming), 10%
polyethyleneglycol, 10 μM spermine, 2 mM ascorbic acid, 100 mM glycine betaine and 10 mM CaCl2 in riceseedling
cv. Khao Dawk Mali 105 under drought condition. Rice seeds were primed for 48 hrs and grown hydroponically
in half-strength Hoagland solution for 21 days. Rice seedlings were then subjected to drought stress by adding15%
polyethyleneglygol to the nutrient solution, except the control group which was hydroprimed seedling grown in
regular nutrient solution. The results showed that all priming treatments with chemicals have a potentially improved
seedling growth, relative water content, total chlorophyll content and total soluble sugar under drought stress over
hydropriming.More physiological traits and antioxidant enzyme activities will be further investigated to determine
the most effective chemicals for seed priming in order to improve drought tolerance in rice.
