Easy and fast seedling method for hybrid pear seeds

The invention discloses an easy and fast seedling method for hybrid pear seeds, which comprises the steps of fruit management, seed management and seedling management, wherein the fruit management is as follows: hybrid fruits can be collected in 5-10 days before morphological maturity and are aired and pre-arranged for 3-4h, and then are instantly arranged in a miniature mechanical refrigeratory for refrigeration under the temperature of 3-5 DEG C and a humidity of 85-95 percent; and the hybrid fruits can be stored until the first ten-day period of January in next year in the refrigeratory; the seed management is as follows: the hybrid fruits are delivered from the refrigeratory and are immediately cleaned and then are aired for 48h under a room temperature (0-10 DEG C); then the hybrid fruits are dipped for 0.5-1.0h by formaldehyde (formalin) 100 times liquid with a concentration of 40 percent; and then the hybrid fruits are directly sown without sand storage and lamination; and the seedling management is as follows: when the cotyledons of the seedlings are developed to two cotyledons and one core, the cotyledons are directly transplanted to a selective nursery in the current year with a permanent planting density of 2.0m*1.0m; and only the central trunks of the seedlings are maintained for extended growing so as to increase the height of crowns and try to enter the 'childhood length' of the adult stage as early as possible and shorten the childhood period.

High output and good quality aubergine graft and transplantation technique in different seasons

The invention relates to a technology for grafting and transplanting of a high-yield and high-quality anti-seasonal eggplant, which comprises the following steps: (1) a common eggplant is taken as a graft and Solanum torvum is taken as a rootstock; (2) the seeds of the Solanum torvum are used for raising seedlings in July, and the seeds of the eggplant are used for raising seedlings in August; when the seedlings of the Solanum torvum grow 7-9 true leaves and the seedlings of the eggplant grow 4-5 true leaves, the seedlings are taken out; (3) a growing point which is 60-80mm from the root of Solanum torvum is cut off, and the end of the rootstock is cut into a wedge shape; the eggplant seedling is cut into a bevel opening at the eggplant seedling 60-80mm above a cotyledon from bottom to top, and the wedge-shaped end of the rootstock is inserted into the bevel opening of the graft with cortex aligned, and then the graft opening is bound up and fixed to form a two-root seedling; (4) the two-root seedling is transplanted into a field while grafting; after 10-15 days upon transplanting, when the wounds of the rootstock and the graft heal, the graft root is cut from the bottom of the graft opening with only the root of the rootstock left. The technology can cause the anti-seasonal eggplants planted in autumn and winter to have more strong vitality and the ability against diseases and insect pests; in addition, the eggplant planted by the technology has high yield and high quality, the seedling raising method is simple, the grafting seedling rate is high, thus the technology can realize transplanting seedlings into the field while grafting, which reduces the land, labor labor and production cost required by seed bed management.

Convenient and rapid DNA extracting method of peanut health tissues and diseased tissues

The invention relates to a convenient and rapid DNA extracting method of peanut health tissues and diseased tissues. The method comprises two steps of: sample materials preparation: testing the leaf and stem tissues, shell tissues or peanut cotyledons, the weight of which is 3-10 mg, adding the sample materials into a 1.5ml centrifugal tube preset with an alkaline lysate or enzymolysis liquid, and grinding by a grinding rod till the visible particles do not exist; DNA extracting liquid preparation: treating the ground sample materials by an alkaline decoction method or a enzymolysis method to obtain the DNA extracting liquid. The method is also suitable for peanut health tissues and diseased tissues. Compared with the DNA extracting method, the invention has short required time, the required time of single sample by the alkaline decoction method does not exceed 20min, and the required time of single sample by the enzymolysis method does not exceed 0.5h; the dosage of the sample is little, and each sample only needs 3-10mg; the method has no need of liquid nitrogen to grind, therefore the cost is low, and the requirements of peanut molecule marker auxiliary breeding and transgene breeding are satisfied. The invention has no influence on the plant growth or seed germination, and has significant meaning on the practicality of peanut molecule breeding technology.

Micropropagation method of fraxinus rhynchophylla

The invention discloses a micropropagation method of fraxinus rhynchophylla and relates to the micropropagation method. The problems of long reproductive cycle, low reproduction efficiency and poor offspring genetic stability in nursery stock propagation of fraxinus rhynchophylla are solved. The method comprises the following steps of: 1, sterilizing fraxinus rhynchophylla seeds, and culturing single cotyledons of zygotic embryos to obtain cotyledonal cell embryos; 2, performing maturation cultivation on the cotyledonal cell embryos; 3, performing sprouting cultivation on the cotyledonal cellembryos subjected to maturation cultivation to obtain regenerated plants; and 4, transplanting the regenerated plants into a culture medium to culture until new leaves are completely unfolded, and removing a covered plastic thin film. The micropropagation method has the advantages of short nursery stock reproductive cycle, high reproductive rate (culturing for 60 to 70 days) and high reproductionefficiency (each explant can generate 15 to 20 somatic embryos); the germination rate of the somatic embryos is up to 87 to 89.55 percent; the transplanting survival rate of the regenerated plants isup to 75 to 80 percent; and the regeneration plants with the same good characteristics as female parents can be generated in mass.
