摘要:
加拿大红叶紫荆是早春重要的观花树种,其种子的休眠特性,严重阻碍了该物种的开发利用。通过对新成熟加拿大红叶紫荆种子形态结构、种子发芽率、种子吸水率以及打破休眠的不同方式(损伤种皮、冷层积、浓硫酸和湿热处理)的试验,研究加拿大红叶紫荆种子的休眠类型及打破方式。结果表明,新成熟的加拿大红叶紫荆种子不能吸水;划破种皮后可将萌发率提高到12%,说明种子具有物理和生理休眠的双重属性;通过划破种皮、30 min的浓硫酸处理或5 min 80 ℃温水处理均可以有效打破物理休眠,而通过3个月的4 ℃冷层积或500 mg/L赤霉素处理可以有效打破生理休眠。综上所述,损伤种皮+低温层积或赤霉素处理的方式可有效打破加拿大红叶紫荆种子的休眠。
