  Variations of critical temperature $T_c$ and in-plane critical field $H_{c2}$
of $\text{Sr}_2\text{Ru}\text{O}_4$ under uniaxial stress have recently been
reported. We compare the strain dependence of $T_c$ and $H_{c2}$ in various
pairing channels ($d$-wave, extended s-wave and $p$-wave) with the experimental
observations, by studying a three-band tight-binding model that includes
effects of spin-orbit and Zeeman couplings and a separable pairing interaction.
Our study helps narrow down the possibility of pairing channels. The importance
of the multi-band nature of $\text{Sr}_2\text{Ru}\text{O}_4$ is also
highlighted.
