Belowground bud bank and its relationship with aboveground vegetation under watering and nitrogen addition in temperate semiarid steppe

In temperate perennial grasslands, the recruitment/regeneration of aboveground vegetation predominantly relies on belowground bud bank. Thus, understanding how belowground bud bank density and composition respond to global changes is essential to explain and predict plant community dynamics and ecos...
