Embodiment 7～8
Repeat embodiment 1～2, following difference is arranged: adopt 10% NaCl solution.
Application Example 1
Get the naked kind of the MSK326 kind of 100g, measure the initial moisture content of tobacco seed with moisture teller.Seed is put in the beaker that fills clear water, constantly stirred, behind seed soaking 4～5h, pull the seed (water surface seed) of bubbling through the water column out, standby.In beaker, add NaCl, make concentration and be 2.0%, 3.5%, 4%, 5%, 7% and 10% NaCl solution, fully stir, after leaving standstill 5min, pull the seed (liquid level seed) that swims in solution surface out, leach residue seed (seed at the bottom of the liquid) then, after washing repeatedly with clear water respectively, standby.Seed at the bottom of water surface seed, liquid level seed, the liquid is put into baking oven respectively in 40 ℃ of following freeze-day with constant temperature, when seed moisture content is reduced to initial moisture content, take out weighing respectively after, the computes convergence ratio.Sinking ratio (%)=(seed weight at the bottom of the liquid/sample gross weight) * 100% is tested 3 repetitions.
The result shows, in adopting NaCl solution elite seed process, and the solution sedimentation coefficient difference of variable concentrations, sinking ratio difference.By the sinking proportion grading between different disposal, seed is put into the NaCl solution of same concentrations again behind clear water seed soaking 4h, and the shared ratio of seed all is higher than the processing (table 1) of the 5h that soaks seed at the bottom of its liquid.Identical seed soaking time, the shared ratio of seed reduces along with the increase of solution concentration at the bottom of the liquid.In this test, take clear water seed soaking 4h, the seed rate that sinks to 3.5%NaCl solution bottom is higher, reaches 82.6%.
Sink to the shared ratio of NaCl solution bottom seed after the different selected processing of table 1
Germinating energy and germination percentage according to seed at the bottom of YC/T20-1994 (tobacco seed inspection procedure) mensuration water surface seed, liquid level seed, the liquid.
The result shows, same clear water seed soaking time, adopt the NaCl solution elite seed of same concentrations, the germinating energy of selected back seed shows as: seed at the bottom of the liquid＞liquid level seed＞contrast seed＞water surface seed, and each germinating energy that sinks to the seed bottom the solution in handling all is significantly higher than the seed (table 2) of keeping afloat.Each clear water seed soaking time, germinating energy difference is not remarkable between the seed of variable concentrations NaCl solution bottom, wherein with handle T413 be behind the clear water seed soaking 4h with the screening of 3.5%NaCl solution, potentiality of seed the highest (93.3%) at the bottom of the liquid is significantly higher than CK (81.0%).
For germination percentage, same clear water seed soaking time adopts the NaCl solution of same concentrations to separate seed, and the percentage of seedgermination performance of diverse location is similar to germinating energy.As can be seen from Table 2, handle the percentage of seedgermination the highest (93.7%) of T533, be significantly higher than contrast (85.0%), but its germinating energy only is 86.3%, does not have significant difference with contrast.And the percentage of seedgermination of T413 is 93.3%, a little less than T533, and do not have significant difference with it, but this processing seed germination rate is significantly higher than CK.
Table 2 clear water is in conjunction with the selected influence to MSK326 potentiality of seed and germination percentage of NaCl solution
Annotate: the tee representative is handled, and first digit is represented clear water seed soaking time (4 and 5 represent clear water seed soaking 4h and 5h respectively) behind the T; Second digit is represented variable concentrations NaCl solution (0,1,2,3,4,5 represent 2.0%, 3.5%, 4%, 5%, 7% and 10% NaCl solution respectively); Third digit is represented the seed (1 representative floats over the seed on clear water surface, and 2 representatives float over the seed of solution surface, and 3 representatives sink to the seed of solution bottom) that is in diverse location in the solution refining process.
