Effect of GA_3 and Others on Seed Germination and Seeding Vigor of Cucumis sativus L

Seeds of Cucumis sativus were treated with different concentrations of GA3,IAA,NAA and 6-BA.The results indicated not only the time of germination was reduced but also the germination rate,germination vigor and vigor index were improved with the treatment of 200 mg/L GA3,5 mg/L IAA,0.5 mg/L NAA or 0.5 mg/L 6-BA respectively.Among these the treatment of 200 mg/L GA3 can obviously enhance the germination rate,germination vigor and vigor index.They can enhance the seeding previous growth of Cucumis sativus better.
