Abstract |
Drought stress usually affects northeast region of Thailand resulting in lower rice yield. This research aimed
to study the effects of seed priming in different agents including distilled water (hydropriming), 10% polyethylene
glycol, 10 μl spermine, 2 mM ascorbic acid, 100 mM glycine betaine and 10 mM CaCl2 in rice seedling cv. Khao
Dawk Mali 105 under drought stress. Rice seeds were primed with the chemicals for 48 hours in ambient
temperature. Rice seedlings were grown hydroponically in half-strength Hoagland’s solution pH 5.0 for 21 days.
Seedlings were then subjected to drought stress by adding 15% polyethyleneglycol to the nutrient solution, except the
control group which was grown in the typical nutrient solution. Under drought stress, the results showed that seed
priming agents improved relative water content, proline accumulation and activity of antioxidant enzymes compared
to hydropriming. Therefore, it can be concluded that seed priming with the chemicals can enhance drought tolerance
in plants. |
