Embodiment 1

[0027] The propagation method of the new variety Pistacia chinensis of the embodiment of the present invention comprises the following steps:

[0028] Step 1, fruit collection and cold storage: collect ripe fruits of Pistacia chinensis, dry and refrigerate at a temperature of 0-5°C until February to April of the next year; seeds of plants, especially woody plants, have a dormancy period. Refrigeration is to pass the dormant period for them. Seeds picked in autumn will not germinate if seedlings are grown that year because they are dormant. Even if you insist on sowing seeds, when winter comes and the temperature drops, the seedlings will not emerge, and even if the stalks emerge, they will freeze to death. Therefore, it is usually sown in the spring of the second year.

[0029] In early autumn, select fully mature fruit ears on strong, firm and plump female plants, without separating the seeds and pulp in the ears, and directly dry the fruit ears containing seeds until the w...

Embodiment 2

[0039] A kind of breeding method of new variety Pistacia chinensis comprises the following steps:

[0040] Step 1, fruit collection and cold storage: In September of the same year, the mature fruit of Pistacia chinensis on the female plant is selected, which is strong and plump, and dried and refrigerated at a temperature of 4°C until March of the next year;

[0041]Step 2, germination of seeds: the refrigerated fruit is rolled to remove the pulp, and then the seeds are screened out, and then the seeds are soaked in an auxin solution composed of naphthaleneacetic acid with a concentration of 100ppm and gibberellin with a concentration of 100ppm at a temperature of 20°C 5 days;

[0042] Step 3, disinfection of the germinated seeds: soak the germinated seeds in 500 times liquid of 50% carbendazim wettable powder or 500 times liquid of 50% thiophanate for 24 hours;

[0043] Step 4, sowing: Spray the seedbed with 50% carbendazim wettable powder 500 times liquid or 50% thiophanate...

Abstract

The invention discloses a breeding method of a new variety red leaf Pistacia chinensis Bunge. The method includes: drying and refrigerating collected seeds, and soaking the seeds in an auxin solution to germinate the seeds; employing a bactericide to perform sterilization and disinfection on the germinated seeds and seedbed, and at the same time conducting sterilization and disinfection on seedlings. According to the invention, optimal seed sources and collected seeds are dried and then preserved at low temperature, the auxin solution is employed to soak and germinate the seeds, so that the seed germination rate is increased from 1-3% to 10-15%. The bactericide is adopted for sterilization and disinfection of the germinated seeds and seedbed, and sterilization and disinfection are simultaneously carried out on seedlings, so that the seedling emergency rate of the seedlings is enhanced from 20-30% to 80-90%. Both the naphthylacetic acid and gibberellin used by the method provided by the invention have the functions of breaking plant seed dormancy and promoting seed germination. The method is simple and is convenient to operate, and improves the germination rate.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a propagation method of a new variety of Pistacia chinensis. Background technique [0002] The landscaping plants in Sichuan are mostly green. Although they are evergreen in four seasons, they lack variety, especially the colorful-leaved plants. The garden department has always hoped to introduce and cultivate colorful-leaved plants to enrich the diversity of the landscape. Attempts to introduce existing color-leaved plants from other regions at home and abroad are tried in areas such as Chengdu, but all fail. Red-leaved Pistacia chinensis is a new variety of garden plants selected from the wild variation of Pistacia chinensis in the Anacardaceae family, named "Huaxiahong". It grows well in the Chengdu Plain and the surrounding areas of the western Sichuan Basin, and has strong adaptability. Especially in the environment and climate conditions of low altit...
