| 摘 要： | 研究赤霉素(GA3),冷湿和温度 对五个种源的印度冷杉(Abies pindrow)和长叶云杉(Picea smithiana)种子萌发的影响.种子被浸泡在GA3 (10 mg(L-1)中24小时,然后在3(5(C温度的条件下冷藏15天.设计4个温度(10(C, 15(C, 20(C 和 25(C)条件来促进种子的萌发.结果表明,浸泡和冷湿处理明显增加种子的萌发率.在10 (C时种子的萌发率最高.总体结果表明,种子被浸泡在GA3 (10 mg(L-1)中24小时,冷湿藏15天,可以有效地促进印度冷杉和长叶云杉的种子萌发.统计数据表明,浸泡处理、温度和种源以及与温度的相互作用都对种子的萌发有明显的影响.

| Abstract: | A study was conducted to evaluate the effect of GA3, moist-chilling and temperature on seed germination of Abies pindrow and Picea smithiana from five different provenances. Seeds were soaked in GA3 (10 mg·L−1) for 24 h, then chilled at 3–5°C for 15 days. Four temperature regimes viz. 10°C, 15°C, 20°C and 25°C were used for stimulating
seed germination. Results showed that soaking and chilling significantly increased germination percentage. The germination
percentage was highest at 10°C. Overall results showed that soaking seeds in GA3 (10 mg·L−1) for 24 h, moist chilling for 15 days, and germinating at 10°C produced an effective germination in both the species studied.
The statistical analysis of the data proclaimed significant effect of treatment, temperature, provenance and treatment with
temperature interactions on seed germination. |
