摘　　要：以马铃薯品种‘大西洋’为材料,研究外源5-氨基乙酰丙酸(ALA)对马铃薯生长和产量的影响,探讨ALA的最佳施用浓度和时期。结果表明,当ALA浓度≤200 mg/L时,对马铃薯生育期、植株性状、块茎性状及产量均无明显影响;当ALA浓度增加到300 mg/L时,产量大幅度提高,其中以浓度600 mg/L在现蕾期喷施产量最高,达到46 384 kg/hm2。5-aminolevulinic acid(ALA)was studied for its effects on potato growth and yield in order to understand optimal concentration and application time using the variety'Atlantic'as plant material.No obvious impacts were found for growth period,plant traits,tuber traits and yields of potatoes when ALA was applied at a concentration of≤200mg/L.However,when ALA was applied at300mg/L or more,yield was increased dramatically.Yield reached up to46384kg/ha when applied at the concentration600mg/L and bud flower stage.
