Overview

Experiments evaluated priming methods to improve germination and seedling vigor in rice, indicating effective solutions for better crop establishment.

Key Points

  • The research aims to evaluate different seed priming methods to enhance seed germination and vigor in rice under aerobic conditions.
  • Conducted an experiment under a completely randomized design (CRD).
  • Applied treatments including osmopriming, halopriming, hormopriming, and control (no priming).
  • Measured germination percentage, speed, vigor indices, and mean germination time after 12 hours of soaking.
  • Osmopriming with –0.1 MPa PEG 6000 and hormopriming with 200-300 µg/mL GA3 improved germination percentage significantly.
  • Highest germination observed with GA3 (92.7%), followed by sodium selenate (91.3%) and KNO3 (89.3%).
  • Field emergence was notably higher with GA3 (85%), sodium selenate (84%), and KNO3 (82.7%) compared to control (73%).
