Seed Technology

Natural

Seeds is in natural form without any treatment. The main process of this form should be passed grading andcleaning process in order to achieve high quality of seeds size and purity. Usually raw seeds price will be much more economy than other forms depend on customer requirement.

Coating

Some plant species produce seed that has a very flat or irregular shape and, as a result, is complicated to single-sow. Coating the seed to give it a rounder shape and smoother surface can help to solve this problem. Thicker coatings tend to be used to improve sowability. This type of coating is also called encrustation. Thinner coatings are used to make seed placement easier to identify during the sowing process, and to act as markers.

Pelleting

Some crop species have extremely small seeds which cannot be single-sown. For this reason the raw seed is
pelleted. The seed is coated to build a pellet that is approximately 5 to 20 times the size of the actual seed it
contains. Pellets allow plug growers to easily sow and control the number of seeds per cell.
Optimal storage: 3 months at 41 °F ( 5 °C )

Multipellets

Multipellets are just like standard pellets except each pellet contains several seeds. This makes producing some species e.g. like Lobelia, Begonia, Gaillardia, and Pentas easier by producing a bushy plant with just one pellet.

Priming

Seed germination is initiated up to a certain stage of physiological development, then the seed is dried back and stored at low temperatures. Primed seeds germinate more quickly and more uniformly. The increased uniformity often continues well into the advanced young plant stage. This faster seedling development allows plug growers to use greenhouse space more efficiently. At the same time, faster seedling development reduces the number of losses that can occur during the critical germination period. Optimal storage: at 41 °F ( 5 °C )

Fuseable

Seed germination is initiated up to a certain stage of physiological development, then the seed is dried back
and stored at low temperatures. Primed seeds germinate more quickly and more uniformly. The increased
uniformity often continues well into the advanced young plant stage. This faster seedling development allows
plug growers to use greenhouse space more efficiently. At the same time, faster seedling development reduces
the number of losses that can occur during the critical germination period. Optimal storage: at 41 °F ( 5 °C )

Lobelia and Lobelia seeds are very small, about 20,000 seeds per gram, and also black when cultured in the culture material will not be seen. Seed technology in multi-platelet coating makes it very convenient.
