摘要:

研究不同贮藏条件(20 ℃室温、4 ℃冷藏、-20 ℃冷冻和野外土壤埋藏)和时间(3,6,12个月)对西鄂尔多斯地区5种荒漠植物(沙冬青、四合木、长叶红砂、蒙古扁桃及霸王)种子萌发的影响。结果表明:贮藏时间和条件对长叶红砂和蒙古扁桃的种子生活力没有显著影响,12个月后的生活力仍达90%以上; 霸王、沙冬青和四合木种子的生活力随着贮藏时间的增加而逐渐下降; 贮藏条件和时间对长叶红砂和蒙古扁桃种子萌发率的影响也不显著; 贮藏条件对四合木和霸王的种子萌发率影响不显著,而贮藏时间对其萌发率影响极显著; 贮藏条件和贮存时间对沙冬青种子萌发率的影响均极显著。种子贮藏和萌发的特点可为植被恢复提供理论依据。

Abstract:

We studied the effect of different storage conditions and durations on seed viability and germination of five desert rare species, Ammopiptanthus mongolicus , Tetraena mongolica , Reaumuria trigyna, Amygdalus mongolica and Zygophyllum xanthoxylum . The results showed that storage conditions and durations did not significantly affect seed viability of R . trigyna and A. mongolica , which were above 90% after 12 months’ storage. Seed viability of A . mongolicus , T . mongolica and Z . xanthoxylum became lower when storage duration prolonged. Storage conditions and durations also did not significantly affect seed germination of R . trigyna and A. mongolica . Storage conditions had no significant effect on seed germination of T . mongolica and Z . xanthoxylum , while storage duration had significant effect on them. Germination of A . mongolicus was significantly affected by storage conditions and durations. Characteristics of seed storage and germination could provide theory basis for vegetation restoration.
