The yield of nuts from a single cone can vary depending on several factors such as the age of the tree, growing conditions, climate, and specific genetic traits within each species.

Comparison of Nut Yields

- Korean Pine (Pinus koraiensis):
The cones are typically larger than those of the Siberian pine, with an average weight ranging between 150 - 250 grams per cone. Each cone contains approximately 80 - 120 seeds (nuts), which have shells that are relatively easy to crack. The kernel content is usually around 60% by weight, making it quite high - yielding for human consumption.
- Siberian Pine (Pinus sibirica):
In contrast, Siberian pine cones tend to be smaller, weighing about 70 - 120 grams on average. They contain fewer seeds - typically 40 - 60 per cone - and these seeds often have thicker shells, which makes them slightly harder to process. The kernel content is generally lower at around 40 - 50%.

Conclusion

In terms of nut yield per individual cone, the Korean pine tends to produce more kernels with higher extraction efficiency due to its larger size and easier - to - crack shells. Comparatively, the Siberian pine has smaller cones with thinner seed yields and less efficient processing. However, both species remain valuable for their edible nuts and ecological importance.
