- 摘要:
- 以一串红陈种子为试材，用不同浓度的赤霉素、脱落酸处理后进行标准发芽试验，研究外源激素对一串红种子发芽与休眠的影响。结果表明：适宜浓度（80 mg/L）的赤霉素处理可促进一串红种子的萌发，加快发芽速度，提高发芽活力;适宜浓度（0.1 mg/L）的脱落酸处理可抑制种子萌发，降低发芽速度，促进种子休眠，有利于种子保存。
- Abstract:
- Taking Salvia splendens seeds as test materials,treated with different concentrations of GA or ABA,the effects of plant hormones，GA and ABA on the germination and dormancy of the seeds were studied.The results showed that GA or ABA treatments had obvious effects on germination of Salvia splendens seeds.Both,the germination of the seeds and the vigor of the seedlings were markedly improved by GA treatments.The appropriate concentration (80 mg/L) of GA treatments promoted the germination of Salvia splendens seeds，accelerate speed and vigor of the seeds germination.ABA treatment (0.1 mg/L) restricted the germination，promoted the dormancy of the seeds.
