Problems solved by technology

During the sand storage period, the seeds often rot due to poor control of water or ventilation conditions, or poor control of the length of low-temperature stratification time, which affects the normal release of dormancy of the seeds, resulting in the inability of the seeds to germinate or the low germination rate after sowing. For the hybrid seeds recovered through hybridization, if the seed layering is not handled well and cannot germinate, it will affect the breeding work plan

Embodiment Construction

[0022] Seed germination is one of the necessary prerequisites for the study of morphological and material changes, germination mechanism and germination conditions during seed germination. The application of the method of the invention promotes the germination of the pear pear seeds, and lays the foundation for in-depth research on the dormancy of the pear pear seeds. Low-temperature stratification treatment is one of the commonly used methods for relieving dormancy of fruit tree seeds. After low-temperature stratification treatment, it takes about 30 to 60 days for the seeds of Duli pears with seed coats to relieve their dormancy. The seeds often rot or grasp during sand storage. The length of the low-temperature stratification time is not good, which will affect the normal release of dormancy of the seeds, resulting in the inability of the seeds to germinate or the low germination rate after sowing, resulting in delays in the production season and economic losses. The seeds ...

Abstract

The invention relates to a method for promoting germination through release of pyrus betulaefolia seed dormancy by sodium malonate and belongs to the technical field of plant production. The method for promoting the germination of pyrus betulaefolia seeds comprises the following main steps: 1) collection and cleaning of seeds; 2) seed soaking in clean water and seed disinfection; 3) treatment by a chemical agent and seed cleaning; and 4) sowing. The pyrus betulaefolia seed treated by the sodium malonate is applied, begins to germinate in three days after the sowing and can totally germinate in one week around; and the germination rate is high and can reach more than 85 percent. The method initially finds that the pyrus betulaefolia seed can release the seed dormancy through the treatment of the sodium malonate without low-temperature lamination treatment. The application of the research can effectively shorten the germinating time and cross-breeding cycle of pyrus betulaefolia and simplify the embryo culturing procedure.

Description

technical field [0001] The invention relates to a method for releasing dormancy of pear seeds and promoting germination by using sodium malonate, which is a method for breaking dormancy of pear seeds and promoting seed germination, and belongs to the technical field of plant production. Background technique [0002] Pear is a worldwide fruit tree and the third largest fruit tree in my country. There are many kinds of pear trees, with strong adaptability and wide distribution. They are cultivated in all provinces except Hainan. It is one of the key fruits for the structural adjustment of rural planting industry. Pear fruit has high nutritional value and contains protein, fat, calcium, iron, phosphorus and various vitamins needed by the human body. The pear pulp is crisp, tender and juicy, sweet and sour, some have a strong aroma, and the flavor is extremely beautiful, which is very popular among consumers. The development of pear industry has become an important way to incr...
