摘要：本研究设置干燥、布袋与保鲜袋包装以及系列温度处理 ,开展了 3 a西南桦种子贮藏试验。结果表明 :布袋与保鲜袋处理对西南桦种子贮藏影响极不显著 ;在常温常规条件下 ,西南桦种子贮藏 3个月即失去生活力 ,而在常温干燥条件下 ,西南桦种子贮藏 10个月种子发芽率尚未显著下降 ;在 15°C条件下贮藏 10个月几乎丧失发芽能力。非常有趣的是 ,西南桦种子在 10、5、0°C和 -5°C各温度条件下贮藏 3 a,效果十分理想。 10°C似乎是西南桦种子低温贮藏的临界温度。
Betula alnoides is a valuable fast growing timber species with good perspectives in tropical and warm subtropical areas.A three year s trial was conducted on its seed storage under dry condition,in package sealed or not and under a serial temperature treatment respectively.It is concluded that (1) different package has no remarkable effect on its seed storage;(2) seeds lose their vigor after three month under controlled treatment (no treatment) in Guangzhou, P.R. China while when stored under dry condition,their germination rate do not decline obviously in ten months;(3) seeds nearly lose their germination capacity in 10 months when stored under the temperature of 15 °C,and (4) seeds have been kept well under the temperature of 10 °C,5 °C,0 °C and -5 °C for three years,thus 10 °C seems to be the critical temperature for low temperature method to store the seeds.The results will provide a reference for seed storage of Betula alnoides,and probability to save genetic resource of the species vs.seed in the long term,and will prompt the extension and genetic resource conservation of this species.
