石刁柏种子发芽特性的研究

Study on the Sprouting Character of Asparagus officinalis Seeds

研究了石刁柏种子发芽特性。结果表明:石刁柏种子发芽最适温度为25℃,有无光照对石刁柏种子发芽无明显影响,没有生理休眠期,浸种24h时发芽率、发芽势最高,用不同浓度的GA3浸种16～24h时,200mg/L的GA3提高发芽率效果最好、100～200mg/L的GA3提高发芽势效果最好。

By the study on the sprouting character of Asparagus officinalis seeds, indicated that the most suitable sprouting temperature is 25℃ ,having illumination or not is not obvious influencing on sprouting, the seeds had not physiology dormancy, the sprouting rate and the sprouting power were both the highest when seed soaking time was 24 hours, when using different density GA3 soak seeds 16-24 hours, the effect of using 200 mg/L GA3 was the best and the effect of using 100-200 mg/L GA3 to improve the sprouting power was the best.
