Embodiment

[0013] The test variety of the present embodiment adopts small seed type watermelon 'wmx05' (thousand grain weight 8g):

[0014] Step 1, spreading the seeds in the sun for 2 days;

[0015] Step 2: Immerse the seeds in water at 55°C, stir for about 30 minutes while soaking the seeds, then soak the seeds in 30°C water for 2 hours after cooling; rinse with saturated lime water after taking out, until the skin of the watermelon seeds is free of mucus, then rinse with water until The skin of watermelon seeds has no peculiar smell.

[0016] Step 3: Spread wet gauze on a shallow plate, spread the seeds evenly on the cloth, cover with 1-3 layers of gauze, and incubate in an incubator at 28±2°C for 6 hours. Then take out the seeds from the incubator, wash them with water several times, store them at a low temperature of 4±2°C for 6 hours, then thaw them with cold water, and then culture them at 28±2°C for several days until they germinate.

[0017] Test proves: the germination rate o...

Abstract

The invention relates to a treatment method for watermelon seeds, in particular to a method for germinating small-seed-type (thousand seed weight being less than or equal to 10g) watermelon seeds uniformly, belonging to the technical field of plant breeding. According to the technical scheme, the method comprises the following steps: tedding seeds in the sun for 2d; soaking the seeds in water with temperature of 55 DEG C for 30min, cooling down, and soaking the seeds in water with temperature of 30 DEG C for 2h; washing the seeds with saturated limewater until the skin of the watermelon seeds does not have mucilage or peculiar smell; wrapping the seeds with wet gauze, cultivating in an incubator under the condition of 28+ / -2 DEG C for 6h, then cultivating the seeds under the condition of 4+ / -2 DEG C for 6h, and carrying out temperature-changing treatment repeatedly for a few days until germinating. The method provided by the invention is simple and feasible, can ensure uniform seed germination, has the advantages of low cost and no solvent residue and is suitable for massive treatment of seeds.

Description

technical field [0001] The invention relates to a treatment method for watermelon seeds, in particular to a method for making small-seeded watermelons germinate neatly and uniformly, and belongs to the technical field of plant breeding. Background technique [0002] Watermelon [Citrullus lanatus (Thunb.) Matsum et Nakai] is one of people's favorite raw fruits. Seed size is an important indicator of seed quality (Tang Renhua, Fu Qingzhi. The influence of melon seed size on germination potential, germination rate and seedling quality [J]. Seeds, 1997, 6: 57-58, 60.), seed size Affects seed germination and emergence, and is significantly positively correlated with seedling vigor, with larger seeds having faster germination rates and higher germination rates. Studies have shown that seed size can affect the germination ability of seeds and directly affect the establishment of seedlings (Wu Gaolin, Du Guozhen. Research progress on plant seed size and seedling growth strategies [...
