To be inoculated in different callus inducing mediums after multiple Annual Ryegrass mature seed washing and sterilizing, the MS medium that its different callus tissue culture base contains is identical, its contain 2, the mass concentration of 4-D and 6-BA is as shown in table 1 below, then dark culturing 20d in the culturing room of 25 ± 2 DEG C, observe the quality of callus and add up callus number calculating callus induction rate, its result is as shown in table 1:
Table 1
Note: the different lowercase of same column represents the result of LSD method Multiple range test: difference 2 when capitalization represents that 6-BA concentration is identical, significant difference between 4-D concentration, significant difference (P<0.05) when lowercase represents that 2,4-D concentration is identical between different 6-BA concentration.
From table 1, different 2, comparatively significantly (P<0.05), the Annual Ryegrass callus induction rate difference of different 6-BA concentration induction also comparatively significantly (P<0.05) for the Annual Ryegrass callus induction rate difference of 4-D concentration induction.When contain in described induction of callus 2, the frequency of embryonic callus induction when 6-BA that 4-D is 2mg/L, contain is 1mg/L is the highest, reach 60.42%, and callus growth speed is fast, quality is best, in faint yellow, fine and close, comparatively large (diameter >1cm) particle.
Proceed in different callus subculture mediums by cultivating the callus obtained through callus inducing medium, the MS medium that its different callus subculture medium contains is identical, its contain 2, the mass concentration of 4-D and 6-BA is as shown in table 2 below, then dark culturing 20d in culturing room, observe the quality of callus and add up callus final weight, then calculate value-added coefficient, its result is as shown in table 2:
Table 2
Squamous subculture Main Function is that callus is increased, and is more conducive to turning out more regeneration plant.As shown in Table 2, contain in described callus subculture medium 2, the 4-D averages of value-added coefficient when be 2mg/L, 6-BA being 0.2mg/L are maximum, and callus is flaxen dense granule.Therefore, in stepb, contain in described first callus subculture medium 2,4-D is 2mg/L, and the 6-BA contained is 0.2mg/L.Same, in step C, contain in described second callus subculture medium 2,4-D is 2mg/L, and the 6-BA contained is 0.2mg/L.
On the second callus subculture medium callus being inoculated into variable concentrations glyphosate after 5d, some callus start to occur brownization, there is yellow liquid in some callus bottoms, particle becomes loose, moistening gradually, in water soaking mode, along with the passing of incubation time, some callus gradually brownization are even dead, some callus gradually become milky or white, add up survival rate and the melting brown rate of callus after 20d, as shown in table 3:
Table 3
Note: often the different lowercase alphabet in row end is shown in the significant difference in 0.05 level.
As shown in Table 3, the screening of variable concentrations glyphosate has remarkable impact to the growth of Annual Ryegrass callus, and along with the increase of glyphosate concentration, Annual Ryegrass callus survival rate constantly reduces, and melting brown rate constantly increases.When glyphosate concentration is lower than 500mg/L, Annual Ryegrass callus survival rate is higher than 50%; When concentration is 1000mg/L, survival rate only 6.67%; Concentration be 5000mg/L and above time, survival rate is 0.Therefore, the glyphosate Cmax that Annual Ryegrass callus can bear is 1000mg/L.
By in the Calli Differentiation medium of survival after the second callus subculture medium containing variable concentrations glyphosate is cultivated, cultivation temperature 25 ± 2 DEG C, intensity of illumination 1000lx, the callus of 5d rear section survival starts the bud point occurring peak green, after 10d, Calli Differentiation reaches maximum, differentiation resistance seedling is out light yellow green, and color is shallow compared with the Seedling Color without screening; Part seedling is withered and yellow shape, and through verification experimental verification, when the 6-BA contained in described Calli Differentiation medium is 0.5mg/L, differentiation rate reaches the highest, adds up the differentiation rate of callus after 20d, as shown in table 4:
Table 4
Note: often the different lowercase alphabet in row end is shown in the significant difference in 0.05 level.
As shown in Table 4, after glyphosate screening, Annual Ryegrass phenylacetic acid significantly reduces; Glyphosate concentration is higher, and differentiation rate is lower; Differentiation seedling qualitatively with the seedling breaking up out under normal circumstances difference to some extent.When glyphosate concentration reaches 500mg/L, differentiation rate is 15.38%.When glyphosate concentration reaches 1000mg/L, differentiation rate is 0, and callus is continued growth, but does not occur differentiation.
When seedling grows to 2 ~ 3cm, by the seedling of survival access root media, described root media is only made up of 1/2MS medium, comprises KNO
