Abstract:
OBJECTIVETo investigate the influences of temperature, lightness, storage method, storage time, and gibberellin on seed germination of Gentiana rigescens.
METHODThe germination rates of G. rigescens in different treatments were observed.
RESULT AND CONCLUSIONThe most suitable temperature for the seed germination was 25 degrees C, at which the germination rate was 76.33%. The effect of lightness on the seeds was significantly; the germination rate of the seed was very low. Under the natural condition, the best storage method was dry storage (within 6 months), which could promote the after-ripening of the seed. 100-1 000 mg x L(-1) gibberellic acid could significantly reduce the seed germination time, and 500 mg x L(-1) gibberellic acid increased the germination rate of the seed to 95.00%.
