Abstract:: The effects of gibberellin (GA₃) and germination temperature on Pharbitis purpurea (Linn.) Voigt seeds germination were studied. The results showed that the germination index and germination percentage of Pharbitis purpurea (Linn.) Voigt seeds were higher under 28℃ than 23℃, but the difference wasn’t significant. The germination percentage and germination index of Pharbitis purpurea (Linn.) Voigt seeds were improved observably, and starting time and the final time of the seeds germination were ahead of time with 200 mg/L GA₃ soaking seed.
