壳寡糖对番茄幼苗生长·果实产量和品质的影响

Effects of Chitooligosaccharide on Seeding Growth,Yield and Quality of Tomato

[目的]研究壳寡糖对番茄幼苗生长、果实产量和品质的影响。[方法]以“齐达利”番茄为试验材料,采用盆栽和大田种植的方法,设置不同壳寡糖处理浓度和配施方式,通过测定番茄种子发芽率、脱帽率、株高、茎粗、叶片数、干鲜重和果实中可溶性固形物、游离氨基酸、可溶性糖、番茄红素等指标,比较不同壳寡糖处理浓度和配施方式对番茄种子萌发、植株生长、果实产量及品质的影响。[结果]50 mg/L壳寡糖对番茄种子发芽率提高效果最好;与对照相比,在番茄全生育期配施壳寡糖,可使果实中可溶性固形物、游离氨基酸、可溶性糖、番茄红素含量分别提升17.5%、41.2%、73.3%和178.3%。[结论]适宜浓度壳寡糖可促进番茄种子的萌发,利于番茄幼苗的生长,添加壳寡糖可一定程度上提高番茄果实的产量和品质。

[Objective]To study the effects of chitooligosaccharide on seeding growth,yield and quality of tomato.[Method]The tomato‘Qidali’was used as a test material,the pot and field experiments was adopted,different chitooligosaccharide concentrations and fertilizer application methods were applied.By measuring the seed germination rate,unbonnet rate,plant growth of tomato seedlings and soluble solid conce,free amino acid content,soluble sugar concent,lycopene content in tomato fruit,the effects of different chitooligosaccharide concentrations and fertilizer application methods on seed germination,plant growth,fruit yield and quality of tomato were analyzed.[Result]The concentration of chitooligosaccharide on seed germination of tomato was 50 mg/L.Compared with the control,the soluble solid,free amino acid,soluble sugar and lycopene content in tomato fruit increased 17.5%,41.2%,73.3% and 178.3% in the whole growth period of tomato treated with chitosan oligosaccharide.[Conclusion]Appropriate concentration of chitooligosaccharide can promote the germination and plant growth of tomato,improve the yield and quality of tomato fruit.
