摘要:
钟花樱 Cerasus campanulata 株型优美、花色艳丽，是早春著名观赏花木，开发前景广阔。以钟花樱种子为材料，研究储藏时间、浸种时间和水的 pH 值、温度对发芽的影响。结果表明：（1）钟花樱种子冷藏寿命约 2 年，期间发芽率随储藏时间延长呈先平稳后下降的趋势，种子冷藏至第二年春季发芽率均 >90%；（2）钟花樱种子浸种 36 h 后达到饱和状态（吸水率 36.9%），浸种时间对发芽进程无影响，却对发芽率和发芽势影响显著，浸种 24 h 时发芽效果最好，发芽率和发芽势分别为 83.3% 和 77.3%；（3）酸或碱处理都不利于钟花樱种子萌发，水的 pH 值为 7.0 时发芽率和发芽势均最高，分别为 68.0% 和60.7%；（4）钟花樱种子以 25℃水浸种处理发芽效果最好。

Abstract:
Cerasus campanulata, booming brightly and colorful, is a kind of deciduous arbor and early spring flowering tree, which has a great prospect for development and application. The effects of storage time, soaking time, pH value, and temperature of water on the germination of C.campanulata seeds were researched in this study. The results showed that the C. campanulata seeds"" life was about 2 years under refrigerated conditions, its germination rate was stable at first and then decreased with the prolongation of storage time, which could keep above 90% germination percentage until the next spring. The seeds reached the saturation state after soaking seeds for 36 hours, with a water absorption rate of 36.9%. Seed soaking time did not affect the germination process, but had a significant effect on germination rate and germination potential. The germination effect was the best when the seed soaking for 24 hours, the germination rate and germination potential were 83.3% and 77.3% respectively. Both acid and alkali treatments were unfavorable to seed germination. The germination rate and germinationpotential were the highest when the pH value of water was 7.0, which was 68.0% and 60.7% respectively. The germination effect of seeds soaked in 25 ° C water was the best.
