| 摘 要： | 扁蓿豆品系90-36硬实率高达41%.采用打磨、KNO<,3>、KMnO<,4>、HCI、NaOH、H<,2>O<,2>、H<,2>SO<,4>、赤霉素、高温干燥、热水浸种、低温放置和液氮处理12种方法,探讨破除其种子硬实的适宜方法.结果表明:98%H<,2>SO<,4>处理25～60 min,发芽率可达90%左右,硬实率可下降到8%以下;砂纸打磨能使发芽率达84%,硬实完全破除;30%H<,2>O<,2>处理40 min、400 mg/LGA处理24 h、70℃干燥处理0.5 h、0.3%KMnO<,4>处理2 h可破除部分硬实. |

| Abstract: | Hard seed percentage of Melilotoides ruthenica strain 90-36 is 41%.Treated the seeds with sand paper,KNO3,KMnO4,HCl,NaOH,H2O2,H2SO4,GA,high temperature,hot water,low temperature and liquid nitrogen.The results showed that 98% H2SO4 treated 25 to 60min,the germination percentage could increase to 90% or so,the hard seeds percentage decreased under 8%.Treated with sand paper could increase the germination percentage to 84%,and decreased the hard seeds percentage to zero.Besides,treated with 30% H2O2 40min,400... |
