Abstract EN
Seed germination of loquat (Eriobotrya japonica L.) using concentration and soaking duration of Gibberellin acid (GA3) treatments was studied at the lathhouse of Agriculture Research Centre / Ainkawa / Erbil.
Seed treated with GA3 (200, 250 and 300) mg.L-1 in addition to control at three different soaking time (20, 25 and 30) hr to production strong seedling within a short period.
The study relied on Complete Randomized Design (C.R.D) as a factorial experiment.
GA3 at 250mg.L-1 gave best response (71.19, 86.80 and 98.75) % at 1st, 2nd and 3rd weeks, but as the concentration increased above 250 mg.L-1 the germination rate decreased rapidly but shoots and root length of seedling and vigor index increased during 300 mg.L-1.
Soaking period did not affect significantly on loquat seed germination ratio at 1st and 3rd weeks while in 2nd week after germination the ratio increased significantly with increasing soaking period.
Different effects of combined GA3 concentration and soaking period on the loquat seed germination rate and seedling growth parameters.
More significant effect interactions were obtained in 250 mg.L-1 GA3 with different period times.
