Abstract:

【Objective】 To investigate the effect of β-aminobutyric acid on the application of processed tomato under different salt stresses, and to screen the optimal concentration of β-aminobutyric acid. 【Methods】 The effects of β-aminobutyric acid on the agronomic traits and physiological indexes of two processed tomatoes 'Xinhong 49' and 'Tunhe 5501' under different salt stresses were studied by root irrigation at different concentrations of β-aminobutyric acid during the seedling stage of processed tomatoes under different salt stresses. 【Results】 The application of β-aminobutyric acid under different salt stresses could significantly increase the plant height, leaf area, relative chlorophyll content, MDA content and three protective enzyme contents of the two processed tomatoes, and there were significant differences in the index changes between the concentrations of different β-aminobutyric acids. 【Conclusion】 Applying 0.5 mmol/L β-aminobutyric acid can effectively alleviate the salt damage of NaCl to tomato and enhance the activity of its antioxidant system. 1.0mmol· L-1 BABA can effectively alleviate the salt damage of NaHCO3 to tomato, promote the growth and development of tomato, and improve its salt tolerance.

Key words: β-aminobutyric acid; salt stress; processed tomatoes

摘要:

【目的】探讨β-氨基丁酸对加工番茄种植中在不同盐胁迫下的应用效果,筛选β-氨基丁酸的最佳浓度。【方法】采用灌根方式分别对不同盐胁迫下加工番茄幼苗期施用不同浓度的β-氨基丁酸,研究β-氨基丁酸对两种加工番茄新红49号和屯河5501号在不同盐胁迫下的农艺性状和生理指标的影响。【结果】不同盐胁迫下施用β-氨基丁酸能显著增加两种加工番茄的株高、叶面积、相对叶绿素含量、MDA含量以及三种保护酶含量,不同β-氨基丁酸浓度之间的指标变化存在明显差异。【结论】施加0.5 mmol/L的β-氨基丁酸能有效缓解NaCl对番茄的盐害,增强番茄体内抗氧化系统的活性。1.0 mmol/L 的BABA能有效缓解NaHCO3对番茄的盐害,促进番茄生长发育,提高番茄耐盐性。
