After the sieve net seed (sugar beet bulbs and broken bulbs) of impurities such as small stones, clods, mouse bird droppings, beet plant stems and leaves and small off
Flowers, debris and other non-beet seeds and other plant seeds picked, separated; but also other plant seeds under the sieve pick from impurities separated.
Finally, the impurities on the screen and the screen, all other plant seeds are combined, so separates the sample into pure seeds, other plant species
Child three components and impurities. Then three components were weighed (accurate to 0.001g), in grams (g) that the conversion percentage becomes.

There are carried out in the light conditions, light intensity 1000lx ~ 1500lx, illumination time of 8h.
B.2.9 Test duration
Test duration 10d. Initial counting time 4d, the last time the count was 10d. The number of normal seedlings are calculated.
B.2.10 Seedling Identification
Each plant seedlings must be prescribed standards (B.2.10.1 ~ B.2.10.2) were identified. To identify the main structure of seedling development has
Proceeds to a certain period. In the counting process, well-developed seedlings should sprout normal folds in the paper are detected, the suspected or damage, abnormal
Shaped or uneven seedling, usually column to the last count. Or moldy seeds should germinate seedlings badly decomposed paper wrinkles removed, and at any time
count.
B.2.10.1 normal seedlings
Complete seedlings, seedlings with minor defects or secondary infections are normal seedlings. Identification of normal seedlings specific criteria are as follows.
B.2.10.1.1 complete Seedlings
The main structure seedlings grew well, a complete, uniform and healthy.
a) an elongated primary roots, usually covered with hairs, the end of the fine tip;
b) has an upright, slender and a hypocotyl elongation capacity;
c) having two expansion was leafy green cotyledons.
B.2.10.1.2 seedlings with minor defects
The main structure of the seedlings appear some minor flaws, but in other aspects of a balanced growth, and the same test in quite the full seedlings.
B.2.10.1.3 secondary infection seedlings
Caused by a fungal or bacterial infection, so that the main structure of morbidity and seedling rot, but there is evidence that the source of the disease does not come from the seeds themselves.
B.2.10.2 abnormal seedlings
The entire seedling deformity; fracture; cotyledons than root to grow; two seedlings together; yellowing or whitening; thin; edema-like; the primary root sense
Dye caused by decay.
B.3 retests
When the test in the following cases should be re-tested.
B.3.1 When they find the test conditions, when the seedlings have identification or counting errors, the same method should be used to re-test.
B.3.2 When germination test gap between repeated four times exceeds the maximum allowable gap Table B.1, the same method should be used to re-test
Experience. If the re-test results consistent with the first, the gap does not exceed the maximum allowable gap Table B.2, two tests will be flat
Mean reporting on the results of a single; if re-test and the first results are not consistent, the gap exceeds the maximum allowable gap B.2 table shown,
The same method is used for the third test, the results of two tests until a consistent date and the average of the two tests to fill in
Results list.
B.3.3 In case of power failure, germination boxes (chamber) can not maintain the conditions necessary for seed germination requirements, the batch of samples should be re-measured.
