摘要

Germination tests were conducted by soaking native, wild Helianthus annuus and H. petiolarisseeds in various concentrations of gibberellic acid (GAS) for 1 week, 4°C. For H. annuus, the mosteffective concentrations of GA3 were 1000 ppm (61.7%) and 500 ppm (58.3%). Lower concentrations ofGA3 were less effective. For H. petiolaris, the most effective concentrations of GAS were 1000 ppm(56.1%), 500 ppm (65.0%), and 250 ppm (62.2%) and, again, lower concentrations of GAS were lesseffective. Transplanting the germinated seeds of H. annuus to soil in pots, resulted in nearly 100%success, indicating no apparent long-term effects from the GAS treatment.
