Germination of Acacia cincinnata Seeds Promoted by Applied Electric Field
摘要
Abstract
[Objective]Effect of electric field and treatment time applied to Acacia cincinnata seeds on germination was investigated.[Method]A.cincinnata seeds were treated by electric voltages ranging from 0(CK)to 1.0 kV·cm-1 for 15,30,45,or 60m prior to germination under normal conditions.Indicators of germination displayed by the seeds were analyzed.[Result]The seeds exposed to an increasing electric field for up to 60 m germinated at a rate that showed a down-up-down pattern with a peak at 45m.The germination potential and index were at the highest under 0.6-0.8 kV·cm-1 for 45 m and significantly different from CK(P＜0.05).A best fit regression function between the applied electric field and time was found to be Y = 7.73 + 135.23 X1+ 1.24 X2-86.16 X12-0.00911 X22-0.75 X1 X2at R2 = 0.81(P＜0.05).A cluster analysis indicated an extremely significant effect of the electric field/time interaction exerted on the seed germination index.[Conclusion]The of an electric field and treatment time applied on A.cincinnata seeds significantly affected the germination with a rate peaked under 0.6 kV·cm-1 for 45 m.关键词
