The Rana arvalis tadpoles at 27-40 stages responded to solution of some L-amino acids in concentration 10(-2) mol/l with feeding reactions. The range of perceptible amino acids increased during development from 10 to 16. The best feeding stimuli were aspartic and glutamic acids; amino-acids (proline and oxyproline), methionine, leucine and isoleucine did not evoke the significant reactions. The sensitivity to some amino acids (alanine, glutamine, lysine, ornithine, proline and valine) was 10(-5)-10(-4) mol/l at earlier stages and increased to 10(-6)-10(-5) mol/l during larval ontogenesis.
处于27 - 40阶段的林蛙蝌蚪对浓度为10⁻²摩尔/升的某些L - 氨基酸溶液会产生摄食反应。在发育过程中,可感知氨基酸的范围从10种增加到16种。最佳摄食刺激物是天冬氨酸和谷氨酸;氨基酸(脯氨酸和羟脯氨酸)、蛋氨酸、亮氨酸和异亮氨酸不会引发显著反应。在早期阶段,对某些氨基酸(丙氨酸、谷氨酰胺、赖氨酸、鸟氨酸、脯氨酸和缬氨酸)的敏感性为10⁻⁵ - 10⁻⁴摩尔/升,在幼体个体发育过程中增加到10⁻⁶ - 10⁻⁵摩尔/升。
