This is the simplest way to collect seed. It does not require skilled labour. Collection from natural seed fall is suitable for trees with large fruits, pods, and seeds e.g. Tectona, Gmelina and some Dipterocarps.

4.1 Collecting from natural seed fall

The following tools will be helpful:

4.2 Shaking the tree

Light, rigid bamboo, aluminium or plastic poles 4–6 metres in length can also be used. A hooked branch can substitute if the other tools are unavailable (Figures 10 and 11).

The EU regulates the marketing of plant reproductive material of agricultural, vegetable, forest, fruit and ornamental species and vines, ensuring that EU criteria for health and quality are met. EU legislation applies to genera and species important for the internal market and is based on:

Registration of varieties or material;

Under certain conditions, EU countries may temporarily market seed which does not meet these standards e.g. when a supply shortage occurs mostly caused by reduced germination of seed.

When it comes to seed germination, many people don’t realize that some seeds require cold treatment in order for them to sprout properly. Continue reading to learn more about this cold treatment for seeds and which seeds require cold treatment or stratification.

What is Stratification?

In nature, seeds require certain conditions in order to germinate. Seed stratification is the process whereby seed dormancy is broken in order to promote this germination. In order for the stratification of seeds to be successful, it is necessary to mimic the exact conditions that they require when breaking dormancy in nature.

Is Cold Stratification of Seeds Necessary?

If you are starting cold treatment in the late summer or fall, you can put the seeds in a pot of soil and dig the pot into the ground. The seeds will sprout in the spring. However, if you are starting treatment in the early season, you will want to soak seeds for 12 to 24 hours and put them in a plastic bag or sealable container with equal amounts of sand and peat.
