摘    要:利用自制新型大气压等离子体装置对生菜种子进行处理,研究了不同电压的大气压等离子体处理对生菜种子萌发、幼苗生长及产量品质的影响。试验结果表明:不同电压的等离子体处理对生菜种子萌发的影响效果不同。其中,5610和5950 V处理对种子的萌发有促进作用,种子的发芽势、发芽率、发芽指数、活力指数与对照相比均有所提高,而6290~7310 V处理则抑制了种子的萌发,且电压越高抑制效果越明显。同时,等离子体处理种子α-淀粉酶活性提高,电导率降低,幼苗地上部鲜干质量、地下部鲜干质量、根体积、根活力及过氧化物酶活性也有不同程度的增加。不同电压的等离子体处理促进了生菜定植后的生长发育,产量最高比CK提高12.52%;生菜的维生素C、叶绿素、硝酸盐、亚硝酸盐含量等品质也有所改善。综合来看,5610和5950 V的等离子体处理效果较优。

关 键 词:大气压等离子体  生菜  种子萌发  产量  品质

Abstract:To understand better the effect of atmospheric pressure plasma on lettuce seed germination,seedling growth,yield and quality,we designed a novel atmospheric pressure plasma equipment.The lettuce seeds were treated by the equipment with different voltage from 5 610 to 7 310 V.The results showed that the effects of different voltage plasma treatments on seed germination were not the same.The germination energy,germination percentage,germination index and vigor index of 5 610 and 5 950 V treatments were increased than the control.But the seed germination was restrained by plasma treatment from 6 290 to 7 310 V and the higher voltage,the more restrained.In addition,the activities of alpha amylase were higher,and the conductivities of seeds were lower compared with the control.The fresh weight,dry weight,root volume,as well as root activity,and peroxidase activity were heightened obviously.The lettuce yield of six different voltage plasma treatments were increased,they were 7.53%,12.52%,6.78%,6.09%,6.28% and 8.29% more than the control.The vitamin C,chlorophyll,nitrate and nitrite content of plasma treatments were also improved.In our experiment the effects of 5 610 and 5 950 voltage plasma treatments were better than other voltages.
Keywords:Atmospheric pressure plasma  Lettuce  Seed germination  Yield  Quality
