摘要
【目的】研究外源5-氨基乙酰丙酸(ALA)对加工番茄的影响,为其在加工番茄上推广应用提供基础理论依据。【方法】以加工番茄品种H1015和H3402为材料,分析叶面喷施ALA对功能叶的光合色素含量动态变化及果实产量品质相关指标的影响。【结果】随着叶面喷施ALA浓度增加,加工番茄功能叶的光合色素含量增加。50. 0 mg/L的ALA处理下,H1015的平均产量比对照增加15. 12%,而H3402的平均产量比对照增加12. 01%; H1015的可溶性固形物增加10. 43%; H3402的番茄红素和a/b色差值分别增加14. 06%和13. 86%。【结论】在加工番茄幼果期叶面喷施ALA后,外源ALA参与了加工番茄叶光合色素的合成过程,促进了叶光合色素的合成,提高了加工番茄叶的光合色素含量,不仅促进叶光合作用效率,促进叶光合物质积累,促进加工番茄果实的生长发育,提高产量,影响了各组织器官中光合物质的分配,不同程度地改善了加工番茄部分品质。
【Objective】To study the effect of the foliar application exogenous 5-aminolevulinic acid(ALA)on the fruit yield and quality of processed tomatoes in the field in the hope of providing the basic theoretical basis for its popularization and application in processing tomatoes.【Method】Two processing tomato varieties,H1015 and H3402,were used as experimental materials.Different concentrations of ALA were sprayed regularly on the leaves of young fruits.The relationship between relative indexes of yield and quality of mature fruit and ALA was analyzed.【Result】The content of photosynthetic pigments in functional leaves of processing tomato increased with the increase of ALA concentration in foliar spraying.The average yield of H1015 under ALA treatment(50.0 mg/L)was 15.12%higher than that of the control,while that of H3402 increased by 12.01%.The soluble solids of H1015 increased by 10.43%.【Conclusion】Foliar application of ALA on processing tomato leaves during the fruit development,exogenous ALA is involved in the synthesis of photosynthetic pigments in processing tomato leaves,and improves the photosynthetic pigment content of processed tomato leaves.The efficiency of leaf photosynthesis promotes the accumulation of leaf photosynthetic materials,promotes the growth and development of processing tomato fruits,thus increasing the yield,and also changing the distribution ratio of photosynthetic substances in various tissues and organs,and improves the quality of processed tomatoes to some degrees.
