Embodiment 1, sprouting quality control assays
1, test method
The inventive method (is dried in the shade hereinafter referred to as band strain): when Radix Bupleuri poppyhead sequence fruit color is yellow, its seed is gone up plant part jointly cut off in the lump, stay a 7.5cm, then alignd in the lower end of ground plant part and be bundled into wisp, diameter is 5cm, vertically place in shady and cool ventilation place (temperature 10 DEG C, humidity 55%) and dry in the shade for 14 days, seed is collected after drying in the shade, in shady and cool ventilation place (temperature 10 DEG C, humidity 55%) airing 15 days, airing thickness is 0.75cm, and after airing, shady and cool ventilation place (temperature 10 DEG C, humidity 55%) is deposited in pack.
Existing method (hereinafter referred to as direct threshing): when yellow black occurs in seed, blade whole withered and yellow time cane can be sliced off in the lump together with seed, do not stay stake, carry out threshing, the dry in the sun respectively of cane, seed is done, properly preserves.
2, seed single plant yield, empty flat rate and mature ratio are relatively
Taking Radix Bupleuri plant 3 strain of 2 kinds of picking methods respectively, effective fruit ear number, green grain, Huang Li, brown grain, black grain seed number, flat grain number and full grain number are added up in plant division, calculate empty flat rate.Seed single plant yield and full situation result thereof are in Table 1.
The Radix Bupleuri seed single plant yield of table 1 different picking methods, empty flat rate and mature ratio are relatively
As shown in Table 1, the seed amount difference of two kinds of picking methods acquisitions is big, dry in the shade in the seed of percentage recovery gained with strain, the seed ratio that Maturity is high is high, and Maturity difference is less between seed, single plant yield is high, and empty flat rate is little, and the single plant yield of direct threshing method, empty flat rate and Maturity are all not as the present invention.It can thus be appreciated that, experienced by the process staying strain to preserve after adopting, drying in the shade with strain gathers not only can promote that the seed that Maturity is low changes to the seed that Maturity is high, and the flat rate of sky that seed can be reduced, promote the formation of full seed, the Maturity and yield that can increase kind of subpopulation of gathering of namely drying in the shade with strain.
3, thousand grain weigth and sprouting state compare
Analyzing after tested, the mass of 1000 kernel of the Radix Bupleuri seed of 2 kinds of picking methods and sprouting index are as all different in sprouted startup day, average daily germination rate and total germination rate etc..Table 2 lists the Radix Bupleuri thousand grain weigth of different picking methods, germination rate, sprouting startup day, Seedling length and average daily germination rate etc. and sprouts parameter.
The sprouting parameter of the Qing Chuan Radix Bupleuri seed of table 2 different picking methods compares
