The Cerrado represents the largest savanna of the Neotropics. Nowadays, this ecosystem is threatened by the afforestation by monocultures, such as Pinus spp., leading to serious damage to native herbaceous species. Afforestation of savanna ecosystems can affect their ability to regenerate naturally, which relies on different strategies, such as resprouting from below‐ground bud‐bearing organs. Therefore, we investigated the impact of ca. 50 years of Pinus elliottii plantations, compared to undisturbed areas of Cerrado savanna, estimating the bud bank size by counting buds on bud‐bearing organs. We hypothesized that long‐term P. elliottii plantations negatively affected the bud‐bearing organs, leading to decreases in the bud bank.

长期的松树人工林减少了塞拉多地区的芽库

塞拉多（Cerrado）代表着新热带地区最大的稀树草原。如今，这种生态系统受到诸如松树属（Pinus spp。）等单一文化造林的威胁，严重破坏了天然草种。稀树草原生态系统的造林会影响其自然再生的能力，这取决于不同的策略，例如从地下有芽的器官中繁殖。因此，我们调查了ca的影响。与Cerrado savanna的未受干扰区域相比，ellius樟子松人工林已有50年的历史，可通过对有芽器官的芽数进行估算来估算芽库的大小。我们假设长期的P. elliottii人工林会对带芽器官产生负面影响，从而导致芽库减少。
