Embodiment 1

[0025] (1) When the skin of the fruit is orange-red and the pedicel turns yellow and dry, harvest the mature rose fruit;

[0026] (2) Pack the rose fruit harvested in step (1) in a gauze bag, store at 25°C for 30 days, ripen after completion, cut the fruit with a knife, take out the seeds, and put them in the gauze bag ;

[0027] (3) Soak the gauze bag containing the seeds in step (2) in water for 30 hours, and change the water every 8 hours until the seed embryo absorbs water enough to be full; then rub the seeds to remove impurities on the surface of the seeds, and screen out plump seeds that sink to the bottom;

[0028] (4) Using moss as the substrate, soak the substrate and the plump seeds selected in step (3) for 30 minutes with a potassium permanganate solution with a mass concentration of 0.15%; put the sterilized seeds and the substrate at a volume ratio of 1:1 After mixing, put it in a plastic sealed bag. The total volume of the mixed material should not exceed 1 / 2 ...

Embodiment 2

[0031] (1) When the skin of the fruit is orange-red and the pedicel turns yellow and dry, harvest the mature rose fruit;

[0032] (2) Pack the Chinese rose harvested in step (1) with a gauze bag, store at 24°C for 32 days to complete post-ripening, then cut with a knife to take out the seeds, and put them into the gauze bag;

[0033] (3) Soak the gauze bag with seeds in step (2) in water for 24 hours, and change the water every 6 hours until the seed embryo absorbs water enough to be full; then rub the seeds to remove impurities on the surface of the seeds, and screen out plump seeds that sink to the bottom;

[0034] (4) Using moss as the substrate, use potassium permanganate solution with a mass concentration of 0.2% to soak the substrate and the plump seeds selected in step (3) for 25 minutes respectively; put the sterilized seeds and the substrate at a volume ratio of 1:1 After mixing, put it in a plastic sealed bag. The total volume of the mixed material is one-third of t...

Embodiment 3

[0037] (1) When the skin of the fruit is orange-red and the pedicel turns yellow and dry, harvest the mature rose fruit;

[0038] (2) Pack the Chinese rose harvested in step (1) with a gauze bag and store at 23°C for 35 days to complete post-ripening, then cut the fruit with a knife to take out the seeds and put them in a gauze bag middle;

[0039] (3) Soak the gauze bag containing the seeds in step (2) in water for 36 hours, and change the water every 5 hours until the seed embryo absorbs water enough to be full; then rub the seeds to remove impurities on the surface of the seeds, and screen out plump seeds that sink to the bottom;

[0040] (4) Using moss as the substrate, use potassium permanganate solution with a mass concentration of 0.25% to soak the substrate and the plump seeds selected in step (3) for 20 minutes respectively; put the sterilized seeds and the substrate at a volume ratio of 1:1 After mixing, put it in a plastic sealed bag. The total volume of the mixed...

Abstract

The invention provides a method for promoting rosa chinensis seed to sprout rapidly. The method comprises the steps of storing rosa chinensis fruits for 30-35 days at 23-25 DEG C, taking seeds after postripeness, and placing the seeds in water for soaking till the seeds suck water fully; screening full seeds, sterilizing the seeds and a matrix respectively, then blending, putting the mixture into a plastic bag with the opened upper part, carrying out vernalization on the mixture for 10-14 weeks at 2-4 DEG C, controlling the moisture content of the matrix regularly during vernalization till seeds sprout so as to finish rapid germination of the rosa chinensis seeds. The method has the advantages of being high in seed germination and large in seed treatment quantity, being capable of observing the germination condition of the seeds, occupying small space in freezing and preserving process, and the like. According to the method, the difficulty of germination of rosa chinensis hybrid seeds is overcome thoroughly, a method for getting rid of seed dormancy is found, and the method has important theoretical and practical significance.

Description

technical field [0001] The invention relates to a method for promoting rapid germination of rose seeds, belonging to the technical field of plant seed germination. Background technique [0002] Rose ( Rosa hybrid ) is a plant of the genus Rosa in the family Rosaceae, which is the largest ornamental plant in the world. According to the growth type, it can be divided into miniature, dwarf, low bush, shrub, vine, and vine. Application types include potted plants, cut flowers, dried flowers, gardens (ground covers, shrubs, trees, hedges, etc.). There are more than 35,000 rose varieties in the world, and new varieties are obtained through breeding methods such as hybridization, mutagenesis, and natural budding. Hybrid breeding is the most important means of cultivating new rose varieties. Cultivating seedlings is an important part of rose breeding work, and seed germination is limited by genetic factors, endogenous inhibitory hormones, and external environmental conditions. Th...
