摘要
以披碱草为材料,用150W微波功率分别处理披碱草种子30s、40s、50s、55s、60s和65s,研究不同微波处理强度下内生真菌的致死情况,同时考察微波对披碱草发芽活力的影响。结果表明:150W功率处理40s可以显著降低披碱草内生真菌的带菌率(P<0.05),提高发芽率,促进根、芽的生长(P<0.05)和生物量的积累,披碱草株高提长且对发芽势、发芽指数和萌发活力指数等发芽参数无显著影响;当微波强度较大时对披碱草种子造成伤害。
The effects of microwave on mortality of endophyte of Elymus dahuricus were studied at the microwave power of 150 Wfor 30s,40 s,50s,55 s,60sand 65 s.Germination vigor of E.dahuricus was also evaluated.The results indicated that microwave was effective in killing the endophyte in the seeds.While the endophyte were treated at 150 Wfor 40s,the contamination rate significantly dropped compared with the control.At the same time,the germination rate,hypocotyls length,radical length,plant height and biomass were also promoted after microwave processing,and germination potential,germination index and vigor index of E.dahuricus had no significant effect compared with the control.But the seeds of E.dahuricus were injured when encountered the stronger microwave processing.
