| Relative growth rate (RGR) of plants is a key component of fitness. Theoretically, the RGR of plants would be closely related with biomass allocation. Our mechanistic understanding of the relationship between RGR and biomass allocation under global change scenarios is still limited. We examined the responses of RGR and biomass allocation of Leymus chinensis, a dominant grass in the temperate steppe of northern China, to a wide range of N addition. We found that N addition increased RGR of L. chinensis up to a threshold of 10 g N/m². While leaf and stem weight ratios were positively correlated with N addition rates, root weight ratio showed a negative correlation. The RGR of total biomass was positively correlated with both leaf and stem weight ratios, but... |
