Seedling raising method of peony seeds for oil

Abstract

The invention discloses a seedling raising method of peony seeds for oil. The method comprises the following steps: (1) seed collection and treatment, (2) root promotion and cultivation of seeds, (3)germination acceleration and seedling raising of the seeds, and (4) transplantation and post management. According to the seedling raising method of peony seeds for oil provided by the invention, dormancy of the peony seeds can be effectively broken, the rooting and germinating rate is high, the germination is fast, the operation is simple and convenient, and the seedling breeding method is suitable for large-scale popularization.

Description

technical field

[0001] The invention relates to a method for raising seedlings of peony seeds, in particular to a method for raising seedlings of peony seeds for oil. Background technique

[0002] Peony (Latin scientific name: Paeonia suffruticosa Andr.), belongs to the genus Paeoniae in the family Ranunculaceae, and belongs to deciduous shrubs. Peony seed endosperm is hypertrophic, rich in oil, sugar, amino acid, protein and vitamins, etc. There are 17 kinds of fatty acid components in its seed oil, which is a good oil resource.

[0003] Peony seeds have typical double dormancy characteristics of epicotyl and hypocotyl. In the natural state, the germination process of peony seeds shows stages. The hypocotyls of mature seeds elongate and root under warm temperature conditions. After the low temperature, the epicotyl dormancy was released, and then germinated and unearthed under warm temperature conditions, and then the seedlings grew. However, during the reproduction proce...

[0081] The seedling raising method of peony seed for oil comprises the following steps:

[0082] (1) Seed collection and processing: collect the mature fruit of Fengdan peony in the middle and late August, put it in a cool and ventilated place and spread it out to dry. When the fruit cracks naturally, take out the seeds, and select the mature seeds by water selection;

[0083](2) Root-promoting cultivation of seeds: soak the seeds in an aqueous solution of sodium hypochlorite with a mass fraction of 5% at a temperature of 25°C and three times the mass of the seeds for 5 minutes, take out the seeds after soaking, rinse them with clear water, and drain the seeds surface moisture, immerse the seeds in water with a temperature of 25°C and four times the mass of the seeds for 9 hours, take out the seeds, spread them in the shade for 6 hours, and then place the seeds in a tray with matrix I, each Put a seed in the hole tray, the seed is buried in the matrix I to a depth of 1 cm, and...
