review text: The authors analyze the monotonicity of period function of the planar generalized quadratic Lotka-Volterra systems. By taking two invariant lines as new coordinate axes and making a constant time scale change to transform the systems and simplify the first integrals, it is proved for the case without complex invariant lines that the period function is monotone increasing.
