EFFECT OF PP333 AND GGR6 On Seed Germination OF Astragalus Adsurgens AND Melilotus Suaveolens
In order to investigate the impact of seed germination of two plant growth regulators PP333 and GGR6 for Astragalus adsurgens and Melilotus suaveolens,this study used a single factor method and selected Astragalus adsurgens and Melilotussuaveolens for the study,and used a concentration of 0,50,100,150,200 mg/L.PP333 and GGR6 solution soaking the seeds for 2h,with no soaking as control,in light incubator for seed germination test.The results showed that:① With the PP333 concentration increases,Astragalus adsurgens seed germination rate increased at first then decreased;and GGR6 play no obvious effect for seed germination of Astragalus adsurgens.② Melilotus suaveolens seed germination rate increased with PP333 concentration;and with concentration of the solution GGR6 increased as well.Conclusion was that:100mg/L PP333 solution can significantly promote seed germination ofAstragalus adsurgens,germination rate was:81.33％;Melilotus suaveolens seed germination of the most favorable treatment is a concentration of 200mg/L PP333 solution,which,germination rate was:84.33％,19.33％ higher than the control.
