Abstract
The invention discloses a method for increasing the germination rate of Korla fragrant pear parental hybrid seeds. The method comprises the following steps: picking full ripe hybrid fruits, placing the fruits in a cold storage at a temperature ranging from -1.5 to 0 DEG C for carrying out after-ripening, taking out the fruits from the cold storage, taking seeds, cleaning the seeds taken out, drying in the shade, soaking the seeds in warm water at 55 DEG C, then soaking for 12 hours when the temperature of water is naturally lowered to room temperature, then fishing out the seeds, cleaning by clear water, carrying out seed soaking disinfection on the hybrid seeds for 5-10 minutes by 0.5% potassium permanganate, and depositing the seeds by disinfected clean river sand, uniformly mixing and stirring the treated seeds with the river sand in a ratio of 1:5, tightly wrapping by cotton gauze with good breathability, then covering with the treated river sand, and refrigerating in a refrigerator at a temperature of 4 DEG C. According to the method disclosed by the invention, the germination condition is checked when the seeds are deposited for about 50 days, and the germination rate of the seeds can be up to 85% and above when the seeds are deposited for 55-60 days.
Description
Technical field
The invention belongs to field of plant variety breeding technology, be specifically related to a kind of method improving Kuerle delicious pear hybrid seed germination rate.
Background technology
Kuerle delicious pear originates in Xinjiang, China Kuerle.The thin meat of this bergamot pear skin is thin, and juice multi-flavor is sweet, crisp tasty and refreshing; Pole storage tolerance and the advantage such as region is extremely strong.Ripe fruit in season face is yellowish green, and sunny side has blush, becomes cadmium yellow after storage, and the micro-band of pulp white is green, and meat is tenderly white, and quality is crisp, and juice is how dense sweet, aromatic flavour.According to science assay, Kuerle delicious pear is of high nutritive value, sugar content 10%, acid 0.03%, ash content 0.12%, and every 100 grams of bergamot pears are containing vitamin C about 4.3 milligrams, and edible part reaches 83.6%.
Applicant is that breeding parent material has done a large amount of crossbreeding work, for the sustainable development of Kuerle delicious pear breed improvement and bergamot pear industry provides support with Kuerle delicious pear.Applicant obtains a kind of method improving Kuerle delicious pear hybrid seed germination rate by hybrid seeding, yet there are no the report of related fields.
Summary of the invention
The present invention aims to provide and a kind ofly improves the method that Kuerle delicious pear is the hybrid seed germination rate of parent.
The present invention is achieved through the following technical solutions:
Improve a method for Kuerle delicious pear hybrid seed germination rate, it mainly comprises the following steps:
1) pluck: pluck after hybridization fruit maturation, for obtaining ripe seed;
2) after-ripening: be placed in time in freezer by the fruit after harvesting and carry out after-ripening, the temperature of freezer controls between-1.5 DEG C ~ 0 DEG C;
3) clean: fruit is got kind after freezer takes out, getting in the process of planting the seed needing to remove flat grain and breakage, and the seed taken out is cleaned, dried in the shade;
4) hot water treatment of seeds: warm water seed being put into 50-55 DEG C soaks, naturally cool to after room temperature until water temperature and soak 12 hours again, then pull seed out and clean with clear water;
5) seed treatment: with 0.5% potassium permanganate, the hybrid seed after soaking is carried out disinfection 5-10 minute, pull seed out and rinse with clear water clean;
6) lamination: the seed processed and river sand are mixed in the ratio of 1:5 and mixes thoroughly, tight with the cotton gauze parcel of good permeability, then the river sand after Mulching treatment, put into refrigerator cold-storage, temperature controls at 4 DEG C.
The standard of described seed maturity is that seed coat is sent out brown, and seed is full.
Described ripening time is 110 ~ 130 days.
Described river sand clean water 2-3 time, washes away alkali, soil, then carries out disinfection to it with boiling water, has controlled moisture content and again river sand has been spread out the moon and dry in the air, and grabbing agglomerating, loose the opening of hand when river sand hand can carry out lamination.
The inventive method earthing of seeds started to check germination by about 50 days, and as lamination 55-60 days, percentage of seedgermination can reach more than 85%.
Beneficial effect of the present invention is: prior art is after fruit maturation, place at room temperature, Deng fruit completely rot after take out seed, and then carry out sand Tibetan, the hybrid seed germination rate that this method obtains is generally between 10% ~ 20%, the innovation of technology of the present invention is, ripening fruits after harvesting is first placed in freezer and carries out low temperature treatment, get after planting seed disinfection, again seed is placed on constant low temperature and carries out lamination, the germination rate of hybrid seed can be made to bring up to more than 85%.
