Effects of the length of plant growth and phenological phases on
plant biomass
The length of the rapid growth phase was significantly (p< 0.05) negatively correlated with the intrinsic growth rate
in four species (Fig. S7). The length of the vegetative growth period
was significantly negatively correlated with the length of the
generative growth period in four plant species (Fig. S7).
The plant biomass of Kobresia humilis was significantly
negatively correlated with the length of the vegetative growth period
but positively correlated with the length of the generative growth
period. The plant biomass of Astragalus laxmannii was
significantly negatively correlated with the length of the rapid growth
period and positively correlated with the intrinsic growth rate. The
plant biomass of Stipa purpurea and Artemisia scoparia was
only significantly correlated with the length of the vegetative growth
period (Table S2).
