几种外源激素对番茄种子萌发及幼苗生长的影响

摘要

试验以红果王番茄为试材,采用浸种催芽的方法,研究了赤霉素(GA3)、萘乙酸(NAA)及6-苄氨基嘌呤(6-BA)等外源激素对番茄种子萌发及其幼苗生长的影响.结果表明,外源激素GA3,NAA和6-BA都可促进番茄种子萌发和幼苗生长;与CK相比,GA3的质量浓度为90 mg/L时,效果最好;而NAA与6-BA的理想浓度则分别为2,12 mg/L.%Tomato varieties red king with seed soaking was used to investigate the effects of gibberellin (GA3),naphthalene acetic acid (NAA) and 6-Benzylaminopurine (6-BA) on tomato seeds germination and seeding growth.The results showed that exogenous hormones GA3,NAA and 6-BA could promote the seed germination and seedling growth of tomato.Compared with CK,the treatment GA3 with 90 mg/L could obviously enhance the seeds germination and seedling growth.However,the ideal mass concentrations NAA and 6-BA were 2,12 rmg/L,respectively.
