Problems solved by technology

[0008] Adopting the above-mentioned method cannot meet the needs of industrialized production, and other researchers have carried out research on rapid propagation of axillary buds, for example: "Promoting Axillary Bud Branching Rapid Propagation and Rooting Induction of Jatropha Curcas" published by Li Hua, Zeng Ni, Jia Yongjiong, etc. ("Journal of Sichuan University: Natural Science Edition", 2006, 43 (5): 1116~1120.), the explants used are the embryos germinated from seeds to induce proliferation
However, there has not been a publicized breeding technique that uses regenerated buds to induce proliferation

Embodiment 1

[0049] In this example, wild jatropha seeds in Yuanmou, Yunnan were used as materials. Please refer to Table 1 for the total number of samples and the number of survivors after each treatment step. The main process steps are as follows:

[0050] Proliferation induction step S2: Cut off the differentiated regenerated shoots and insert them into the proliferation medium MP8, namely MS+1.0 mg / L 6-benzylpurine+0.01 mg / L indolebutyric acid+0.025 mg / L silver nitrate , and added 3% sucrose and 0.7% agar, pH 5.8, the temperature was controlled at 24°C, and the light time was 12 h / d for 30 days, and the light intensity was 1800 lx.

[0051] Elongation culture step S3: Excise the proliferated cluster buds and inoculate them into elongation medium SEB3, namely MS+0.3 mg / L 6-benzylpurine and 0.25 mg / L gibberellin, and add 3% sucrose and 0.7% agar, pH 5.8, to induce elongation of stems and leaves. The culture temperature was controlled at 24-26°C, the light time was 12 h / d and cultured fo...

Embodiment 2

[0055] In this example, wild jatropha seeds in Yuanmou, Yunnan were used as materials. Please refer to Table 1 for the total number of samples and the number of survivors after each treatment step. The main process steps are as follows:

[0056] Proliferation induction step: cut the differentiated regenerated shoots and insert them into the proliferation medium MP16, that is, MS+2.0 mg / L 6-benzylpurine+0.1 mg / L indolebutyric acid+1 mg / L silver nitrate, Add 3% sucrose and 0.7% agar, pH 5.8, culture temperature is controlled at 26°C, light time is 12 h / d and culture is 35 days, light intensity is 2000 lx.

[0057] Elongation culture step: excise the proliferated cluster buds and inoculate them into elongation medium SEB10, namely MS +2 mg / L 6-benzylpurine and 1 mg / L gibberellin, and add 3% sucrose and 0.7% agar, pH 5.8, induced stem and leaf elongation, the culture temperature was controlled at 26°C, the light time was 12 h / d and the light intensity was 1800 lx for 20 days.

Embodiment 3

[0061] In this example, wild jatropha seeds in Yuanmou, Yunnan were used as materials. Please refer to Table 1 for the total number of samples and the number of survivors after each treatment step. The main process steps are as follows:

[0062] Proliferation induction step: cut the differentiated regenerated shoots and insert them into the proliferation medium MP0, that is, MS+0.1 mg / L 6-benzylpurine+0.01 mg / L indolebutyric acid+5 mg / L silver nitrate, Add 3% sucrose and 0.7% agar, pH 5.8, culture temperature is controlled at 26°C, light time is 12 h / d and culture is 40 days, light intensity is 2000 lx.

[0063] Elongation culture step: excise the proliferated cluster buds and inoculate them into elongation medium SEB1, namely MS +0.1 mg / L 6-benzylpurine and 0.5 mg / L gibberellin, and add 3% sucrose and 0.7% agar, pH 5.8, induced stem and leaf elongation, the culture temperature was controlled at 24-26 °C, the light time was 12 h / d and the light intensity was 2000 lx for 30 da...

Abstract

The invention relates to a method for rapid propagation of Jatropha curcas. The method comprises the following steps: preparing regenerated buds, that is, with mature seeds of Jatropha curca as a material, culturing the mature seeds to obtain aseptic regenerated buds; propagating and inducing the regenerated buds, that is, cutting off the regenerated buds and inoculating the regenerated buds into an enrichment medium for multiplication culture so as to obtain propagated clumpy buds; carrying out elongation culture, that is, cutting off the propagated clumpy buds and inoculating the propagated clumpy buds into an elongation medium so as to obtain uniform buds with their stems and leaves elongated; culturing strong seedlings, that is, inoculating the elongated buds into a strong seedling medium to culture the strong seedlings; carrying out rooting and transplanting, that is, cutting off buds with uniformly grown stems and leaves after strong seedling culture, inoculating the buds into a rooting medium for rooting culture, and carrying out acclimatization and transplanting after roots which accord with requirements for transplanting are generated. According to the invention, regenerated buds are utilized to induce propagation, which enables high proliferation times to be obtained; the method provided in the invention can be used for propagation of superior lines of Jatropha curcas after genetic transformation and opens up a high efficiency approach for artificial propagation of Jatropha curcas, production of de-virus seedlings and mass propagation of superior lines of Jatropha curcas.

Description

technical field [0001] The invention relates to the technical field of biological group seedling cultivation, in particular to a rapid propagation method of Jatropha jatropha. Background technique [0002] Jatropha ( Jatropha curcas L . ), also known as jatropha curcas, jatropha, tung tree, black soap tree, wood peanut, oil reed seed, bright tung tree, stinky sycamore, etc., belonging to Euphorbiaceae ( Euphorbiacea e) Jatropha ( Jatropha L . ), a deciduous shrub or small tree, is a perennial woody oil plant. Jatropha is native to America and widely distributed in tropical and subtropical regions. [0003] Jatropha Jatropha can be developed as a whole plant, and its fruit, branches and leaves can all be utilized. Jatropha seeds have a high oil content and can be processed to make biodiesel. Jatropha seeds, bark, leaves, roots and latex contain biological drug sources with multiple components, which can be extracted to make biomedicine and biopesticides. The process...
