Seed germination characteristics of Gentiana rigescens / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the influences of temperature, lightness, storage method, storage time, and gibberellin on seed germination of Gentiana rigescens.</p><p><b>METHOD</b>The germination rates of G. rigescens in different treatments were observed.</p><p><b>RESULT AND CONCLUSION</b>The 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%.</p>
