Dark Clean Stevia Seeds with high
seedling emergence & germination rates:
Whether you want to grow stevia commercially or for your own garden, clean stevia seeds is always the best choice.
Clean stevia seeds means the debris and feathery
attachments have been removed and rubbed. They are more expensive than the
raw seeds, not only because of
the labour and equipment costs involved, but also because of
the ratio of raw stevia seeds to clean stevia seeds which is 1:4. Every 4 kilos
of raw stevia seeds make 1 kilo of clean dark viable stevia seeds. One gram is approximately 3400 seeds. Germination rate is
65% - 70% if properly planted. Emergence rate is 80%.
Seedling Emergence vs. Seeds Germination:
It is more rewarding when focusing on healthy
seedling you will get by the time of transplanting than focusing on germination rates. Not all sprouted seeds emerge. For example out of 60% germination you could get 80% that emerge. With good emergence one kg of seeds can usually cover 5-7 acres with stevia plantlets but all depends on the experience with stevia seed nurseries, some nurseries gave no seedlings at all, others would yield up to 85% seedlings.
It is also important to consider the critical period between germination and emergence (which lasts several days) during which seedlings must start collecting water from the soil with their new root systems in order to (1) remain alive, and (2) give them the resources to push through the soil and finally emerge. Sub-surface survival (or mortality) of seedlings is a major determinant of the success or failure of the crops.
Tissue culture, cuttings or seeds?
Any stevia project should start with seeds. Some companies sell tissue culture products or cuttings. This method is very costly and risky in terms of surviving transportation plus it’s about 10 times the cost of seeds. Seeds are still the cheapest method of propagation.
Stevioside content:
In terms of stevioside content, early flowering tend to have higher stevioside content. The concentration of stevioside in the leaves increases when the plants are grown under long days. It is better be harvested just prior to flowering when steviol glycoside content in the leaves is maximum. Later when you have 20 or 30 acres covered with stevia, you can use 4 or 5 different methods of propagation to speed up propagation and increase the content of Rebuadioside-A. A good modern seed variety can reach up to 55 - 70% of Reb-A content in the growing leaves.
Seeds Savings:
Stevia seed should remain viable for more than 3 years if stored under dry weather, darkness and low temperature at 0 �C.
