摘要
对金银忍冬种子采用室内干藏、室外冷藏、混沙层积和雪藏层积4种贮藏方法,测定最早发芽天数以及实验室发芽势与发芽率,场圃发芽势与发芽率;对室内干藏的种子进行不同浓度GA3处理,测定其发芽势与发芽率。结果表明:混沙层积与雪藏层积能明显打破金银忍冬种子休眠和提高发芽率,提高发芽率近4倍,提前发芽1个月;赤霉素对金银忍冬种子发芽有促进作用,以100 mg/L发芽效果最佳,提高发芽率近3倍,提前发芽1个月。
Storing the seed of Lonicera maackii by the indoor dry storage, outdoor refrigeration, laminated sand mixed and frozen laminated four storage methods, measuring the earliest days of germination, as well as the laboratory germination rate and the nursery germination rate and the germination energy; for indoor dry storage of seeds of different concentrations of GA3 treatment, with the determination of germination rate and germination energy. The results showed that the sand mixed and the laminated frozen to break the Lonicera maackii pregermination significantly and improve seed germination rate of dormant,improved the germination rate nearly 4 times and 1 month ahead of schedule; GA3 on Lonicera maackii seed to promote the role of seed germination ,and 100 mg/L to deal with seeds the highest germination rate, improved the germination rate nearly 3 times and 1 month ahead of schedule.
