Problems solved by technology

Because the seeds are small, hard and waxy on the surface, the seeds are in a deep dormant state, and the natural germination rate is usually only about 20%, and the germination is irregular, which limits the basic research, development and utilization of Jatropha to a large extent.
The methods that have been studied so far to break dormancy and promote germination of Jatropha seeds are mainly concentrated on the variant of Jatropha jatropha (Jiazia tome

Embodiment 1

[0015] Embodiment 1: Soak 10g jacaranda seed with 40ml10% hydrogen peroxide solution 15min, during non-stop rocking, to more fully destroy the wax layer on seed surface, after washing away the residual hydrogen peroxide on seed surface, it is planted in the soil, The seeds began to germinate on the 12th day, and after 20 days, the seedling rate was 78%.

Embodiment 2

[0016] Embodiment 2: with 40ml20% hydrogen peroxide solution soak 10g jacaranda seeds 10min, during non-stop rocking, to more fully destroy the wax layer on seed surface, after washing away the residual hydrogen peroxide on seed surface, it is planted in the soil, The seeds began to germinate on the 12th day, and after 20 days, the seedling rate was 90%. (See figure 1 )

Embodiment 3

[0017] Embodiment 3: with 40ml10% hydrogen peroxide solution soaking 10g jacarnia seeds 20min, during non-stop rocking, to more fully destroy the wax layer on the seed surface, after washing away the residual hydrogen peroxide on the seed surface, it is inoculated in 1 In / 2MS seed germination medium, the seeds began to germinate on the 12th day, and the seedling rate was 82% after 20 days. The cultivated sterile vaccine can be used in researches such as tissue culture and genetic transformation.

Abstract

The invention discloses an efficient quick sprouting method for idesia seeds. The idesia seeds are soaked in a hydrogen peroxide solution of which the mass percentage is 10% to 30% for 5 to 20 minutes, then are washed with purified water to remove residual hydrogen peroxide on the surfaces of the idesia seeds, and are cultivated. The efficient quick sprouting method has the advantage that due to the treatment of the hydrogen peroxide solution, the germination percentage and planting percent of healthy seeds are as high as 98.5%; the method is cheap, convenient, and suitable for large-scale application.

Description

technical field [0001] The invention relates to a high-efficiency and rapid germination method of Jacaranda seeds, which belongs to the technical field of pretreatment before sowing seeds. Background technique [0002] Idesia polycarpa Maxim., a deciduous tree of the genus Idesia polycarpa Maxim. Because of its straight trunk, rapid growth, non-perishable, and light and soft material, it is a material for making furniture and construction, and is also a good pulp Material; its pulp and seeds can be used to extract oil, the oil is dark yellow, semi-dry, edible, can replace tung oil, and can also be used as a raw material for extracting linoleic acid preparations, paints, coatings and soap making. In addition, after autumn, the red fruit clusters in clusters, which are gorgeous and eye-catching. It is an important tree species for landscape greening. Therefore, as a three-purpose tree species for oil, timber and ornamental, Jatropha has high economic value and important devel...
