Internal Seed Structure of Alpine Plants and Extreme Cold Exposure

摘要: Cold tolerance in seeds is not well understood compared to mechanisms aboveground plant tissue but crucial understanding how populations persist extreme cold conditions. Counter-intuitively, the ability of survive may become more important future due climate change projections. This loss insulating snow bed resulting actual temperatures experienced at soil surface level being much colder than without cover. Seed survival extremely low conferred by that can be divided into freezing avoidance and depending on location ice crystal formation within seed. We present a dataset alpine angiosperm species with seed mass structure defined as endospermic non-endospermic. presented alongside locations temperature minima per which used examine extent different structures are associated hope others demonstrate if certain sizes cover, so, would they negatively impacted from change.
