Effects of altitude gradient on the values of Total respiration rate (a), Alt respiration rate (b), Cyt respiration rate (c) and Residual respiration rate (d) in leaves of Herpetospermum pedunculosum (Ser.) Baill. The plant samples were selected from different altitude (2800 m, 3000 m, 3100 m and 3300 m), respectively. Different letters above bars indicate statistically significant differences between different altitudes at P < 0.05 according to Duncan’s multiple range Test
