Embodiment 1

[0015] Take 150 seeds, rinse them with 1% sodium hypochlorite solution for disinfection, pack them into 3 transparent sealed bags with length×width=15cm×10cm, add 1.5ml of pure water, inflate the sealed bag with air, seal it, and put it flat Lie down in an incubator, set the temperature at 38°C, and wait for germination (the germination time in the incubator is 2 months). Perform the following operations 1 or 2 times a week: Take out the seeds, rinse them with 0.5% sodium hypochlorite solution, and then put them in an incubator to accelerate germination (if you find that the seeds are growing fungus or moldy, take out the seeds and discard them immediately). Once the seeds are found to germinate, they are removed and transferred to a sand bed. Germination results are shown in Table 1.

Embodiment 2

[0018] Take 150 seeds, rinse with 1% sodium hypochlorite solution for disinfection, pack them into 3 transparent sealed bags with length×width=15cm×10cm, add 1.0ml of pure water, inflate the sealed bag with air, then seal it, and put it flat Lie down in an incubator, set the temperature at 39°C, and wait for germination (the germination time in the incubator is 2 months). Perform the following operations 1 or 2 times a week: Take out the seeds, rinse them with 1% sodium hypochlorite solution, and then put them in an incubator to accelerate germination (if you find that the seeds are growing fungus or moldy, take out the seeds and discard them immediately). Once the seeds are found to germinate, they are removed and transferred to a sand bed. Germination results are shown in Table 1.

Embodiment 3

[0021] Take 150 seeds, rinse with 1% sodium hypochlorite solution for disinfection, pack them into 3 transparent sealed bags with length×width=15cm×10cm, add 2.0ml of pure water, inflate the sealed bag with air, seal it, and flatten it Lie down in an incubator, set the temperature at 40°C, and wait for germination (the germination time in the incubator is 2 months). Perform the following operations 1 or 2 times a week: Take out the seeds, rinse them with 0.8% sodium hypochlorite solution, and then put them in an incubator to accelerate germination (if you find that the seeds are growing fungus or moldy, take out the seeds and discard them immediately). Once the seeds are found to germinate, they are removed and transferred to a sand bed. Germination results are shown in Table 1.

Abstract

The invention relates to an accelerating germination method for shell-free type oil palm seeds. The accelerating germination method comprises using abluent solution to soak the shell-free type oil palm seeds, and cleaning and airing the seeds; using a disinfectant to rinse the seeds, placing the seeds into a plump transparent sealing bag filled with air, adding pure water of 2-4ml into every 10 seeds, transferring sprouting seeds to a sand bed, enabling a sand layer with the thickness of 1-2cm to be covered on the sprouting seeds, maintaining moist, transplanting the seeds into a seedling growing bag filled with nutrition soil when the seedlings grow to 9-12cm on the sand bed, and enabling the seedlings to grow into strong seedlings. The accelerating germination method is simple in process, convenient to operate, low in cost and high in efficiency, and can effectively overcome the shortcomings that the shell-free seeds are easy to dry and are subjected to germ infection easily. Germination time is short, the germination rate, the seedling emergency and the strong seedling rate are high, and the method is efficient for accelerating germination and seedling growing of the shell-free type oil palm seeds.

Description

technical field [0001] The invention belongs to the technical field of seedling breeding, and relates to a method for accelerating germination of seeds, in particular to a method for accelerating germination of shellless oil palm seeds. Background technique [0002] Oil palm is an important tropical oil crop, and its oil yield per unit area ranks first among oil crops. Oil palm is divided into three types according to fruit type: thick-shelled, thin-shelled and shellless. The characteristics of the three are thick-shelled seeds, thin-shelled seeds and shellless seeds. The oil palms currently cultivated commercially are thin-shelled oil palms, which are hybrids of thick-shelled and shellless types. Therefore, shellless oil palms play an important role in the breeding of thin-shelled oil palms. [0003] Thick-shelled and thin-shelled oil palms can avoid excessive water loss and infection by pests and diseases because their seeds are protected by the seed shell, and because of...
