The importance of cotyledons for early-stage oak seedlings under different nutrient levels: a multi-species study

X Yi, Z Wang - Journal of plant growth regulation, 2016 - Springer
Oaks produce acorns containing a large amount of reserves in their cotyledons, which are
important for the early development of seedlings. However, it remains unclear at what level …
