Problems solved by technology

[0004] Jatropha curcas is an oil plant, and its seeds have high oil content, so there are many factors that affect the germination rate of the seeds. However, the optimal treatment time and concentration proposed after the seeds are soaked and treated by EMS mutagenesis are not accurate.
However, after removing the seed shell and seed coat and then performing EMS treatment, the workload of the pre-processing is too large
Therefore, the relevant technology is not mature, and there is still room for further improvement in actual production.

Abstract

The invention discloses a method for mutagenizing barbadosnut seeds by ethylmethane sulfonate. The method disclosed by the invention comprises the following steps of: first, performing pre-bud forcing treatment at 30 DEG C on the barbadosnut seeds, selecting the seeds which are broken and exposed with unexpanded radicles after 3-7 days and soaking the seeds in a 0.9% EMS (Ethylmethane Sulfonate) liquor and soaking for 7 hours; forcing buds of the treated seeds at 28 DEG C and culturing for 3-4 days; and sowing mutagenized survival seeds in a soft peat soil substrate with radicles facing downward, and earthing by 1cm to breed. According to the method, the defects in the prior art are overcome, the mutagenizing concentration and time of EMS are reduced and the mutagenizing efficiency of the barbadosnut seeds by ethylmethane sulfonate is improved so as to facilitate selection by mutation of barbadosnut and promote industrialized development of the barbadosnut.

Description

technical field [0001] The invention relates to the technical field of phytochemical mutation breeding, in particular to a method for mutagenic treatment of Jatropha curcas seeds with ethyl methanesulfonate (EMS). Background technique [0002] The energy plant Jatropha curcas (Jatrophacurcas L.), also known as Jatropha curcas, Jatropha curcas, etc., is a deciduous small tree or shrub of the Euphorbiaceae Jatropha genus. It is drought-tolerant and thin-barren, and is mainly distributed in tropical and subtropical regions. . Jatropha curcas is one of the plants with high seed oil content, and is internationally recognized as an ideal raw material for biodiesel preparation, and has high comprehensive utilization value. Jatropha curcas has been listed as a key development target of biodiesel because of its advantages of "not competing with food for land and people for food". Although the Jatropha curcas biodiesel industry has shown a trend of rapid development, it will take a ...
