经过低温贮藏的火炬松种子,由于处在休眠状态,播种前如不进行催芽处理往往不易发芽。一般采用层积法解除休眠,但层积催芽必须将种子与砂混合或层积,置于0°—5℃的条件下一个月左右,种子才能萌动。现介绍一种较迅速而简易的处理方法:先用清水将火炬松种子浸泡2—3小时,捞起种子倒入盛有浓度为30%的双氧水中,以浸过种子为限,浸20—30分钟,然 After the low-temperature storage of loblolly pine seeds, due to being dormant, it is not easy to germinate unless germinated before sowing. Generally stratification method to lift dormancy, but the stratified germination must be mixed with seeds or sand layering, placed under the conditions of 0 ° -5 ℃ for about a month, seeds germinate. Is now introduced a more rapid and easy treatment: first with water to soak the seeds of loblolly pine 2-3 hours, picked up the seeds into a concentration of 30% hydrogen peroxide, to dip the seeds is limited to dip 20- 30 minutes, of course
