Embodiment 1
[0026] experimental method
[0027] The fruits of Brucea javanica were divided into two groups, a blank control group and a group stored at 4°C for 3 days, 6 days, 10 days and 14 days, respectively. Then sterilized with 1% by weight sodium hypochlorite aqueous solution for 15 minutes, rinsed with sterile water 5 times until pH = 7, paralleled four groups for each concentration, and placed 100 grains in each group for full light cultivation in a constant temperature incubator at 30°C, and counted the germination rate every 10 days .
[0028] Table 1 Effect of low temperature storage on germination of Brucea javanica seeds
[0029]
[0030] Experimental results
[0031] As shown in Table 1, when the seeds of Brucea javanica were not stored at low temperature, they began to germinate on the 20th day, but the germination rate was low, and the germination rate was lower than 5.0%; The germination rate can be as high as 1.1%. It reached the peak at 50 days, and about 31.0% of ...
Embodiment 2
[0033] experimental method
[0034] The fruits of Brucea javanica were divided into two groups, one group was not depulped with fine sand (blank control), and the other group was immersed in warm water at 20°C to 30°C for 1 day, and rubbed with 5% by weight of fine sand to remove the pulp. Then disinfect with 1% by weight sodium hypochlorite aqueous solution for 15 minutes, rinse with sterile water 5 times until pH=7, parallel four groups for each concentration, and place 100 grains in each group for full light cultivation in a constant temperature incubator at 30°C, and count germination every 10 days Rate.
[0035] Table 2 The effect of removing the pulp or not on the germination of Brucea javanica seeds
[0036]
[0037] Experimental results
[0038] As shown in Table 2, when the fruit of Brucea javanica was not removed, it began to germinate on the 10th day, but the germination rate was low, and the germination rate was lower than 5.0%; it reached the peak at 50 days,...
Embodiment 3
[0040] experimental method
[0041] The seeds of Brucea javanica were divided into 6 groups, wherein the first group was a blank control; the second group was soaking the fruit of Brucea javanica in warm water at 20°C to 30°C for 1d, and rubbing it with 5% by weight of fine sand to remove the pulp; The first group is to immerse the fruit of Brucea javanica in warm water at 20°C to 30°C for 3 days, and rub it with 5% by weight of fine sand to remove the pulp; the fourth group is to soak the fruit of Brucea javanica in warm water at 20°C to 30°C for 3 days, and rub it with % fine sand is rubbed, to remove the pulp; the 5th group is to immerse the fruit of Brucea javanica in 20 ℃~30 ℃ of warm water for 3d, and rub with the fine sand of 20% by weight, to remove the pulp; the 6th group is to use the fruit of Brucea javanica 20 Soak in warm water at ℃~30℃ for 5 days, and rub with 20% by weight of fine sand to remove the pulp. Then sterilized with 1% by weight sodium hypochlorite aq...
