| 摘 要： | 采用不同浓度的KH_2PO_4处理常温贮藏12个月和18个月的榉树种子,结果表明:KH_2PO_4处理可提高榉树种子的发芽势、田间出苗率、活力指数及细胞膜系统的完整性,提高了种子的活力.在一定范围内,随着KH_2PO_4处理浓度的增加,榉树种子的活力也相应增加,KH_2PO_4处理浓度以3 g/L最佳,处理时间为24 h.

| Abstract: | The seeds of Zelova schneideriana stored in room temperature for 12 month and 18 months were treated by different concentration KH_2PO_4.The results showed that the germination potential,seedling rate in field,vigor index and integrality of cell membrane were improved which seeds treated by KH_2PO_4.From 0-4.0 g/L,the vigor of Zelova schneideriana seeds increased with KH_2PO_4 concentration increasing.3 g/L KH_2PO_4 solution treating 24 h had the best effect. |
