| Abstract:
A series of investigations of the influence of gibbellic acid on the germination of some vegetables and medical plants seeds were carried out at the Medical Plants Department of the Warsaw Agricultural University. The seed soaking, preceding the sowing, in solutions 500, 1000,1500 and 2000 ppm of GA3 improved germination ability of seven species of seeds, Particularly good effects were achieved with Lavandula vera and Atropa belladonna where not only germination ability was increased but also accelerated and even shooting was obtained. An additional positive effect was the acceleration of seedlings growth. A full stimulation effect of GA3 was observed in Lavandula vera after 21 days from the date of soaking. | |
