Embodiment 1

[0022] A kind of method utilizing hormone and cold stratification to break the dormancy of Rowan seed, specifically comprising the following steps:

[0023] (1) Soak the Rowan seeds harvested in the same year in warm water at 40°C for 48 hours, and change the water once after soaking for 24 hours;

[0024] (2) putting the seeds obtained in step (1) into a potassium permanganate solution with a mass fraction of 0.5% for disinfection for 2 hours, and then repeatedly washing the seeds with clear water until colorless;

[0025] (3) Put the seeds gained in step (2) into 100mg / L gibberellin solution and soak for 6h, then take out the seeds and put them into a nylon mesh bag with a mesh size of 40 mesh;

[0026] (4) Lay the nylon mesh bag containing the seeds and the sterilized wet river sand in layers, the mass ratio of the seeds in the nylon mesh bag to the wet river sand is 1:3, stratify at 3°C ​​for 60 days, Stir once every 7d, and the overall humidity of seeds and wet river san...

Abstract

The invention discloses a method for breaking dormancy of sorbus aucuparia seeds by using hormone and cold stratification treatment in the technical field of seed treatment, which comprises the following steps: (1) soaking the sorbus aucuparia seeds harvested in the current year in warm water at 35-45 DEG C for 48 h, and changing water once after soaking the seeds for 24 h; (2) disinfecting the seeds obtained in the step (1) in a potassium permanganate solution for 1-3 h, and then repeatedly washing the seeds with clear water until the seeds are colorless; (3) soaking the seeds obtained in the step (2) in a 100-200 mg / L gibberellin solution for 5-8 h, then taking out the seeds, and putting the seeds into a nylon mesh bag; and (4) placing the nylon mesh bag filled with the seeds and wet river sand in layers, performing stratification for 30-120 days at the temperature of 2-5 DEG C, and turning over once every 5-7 days. During cold stratification treatment of the seeds, the seeds are soaked in gibberellin in advance, the gibberellin gradually plays a role along with prolonging of stratification time, and compared with traditional cold stratification treatment, the germination rate of the seeds is better.

Description

technical field [0001] The invention relates to the technical field of seed treatment, in particular to a method for breaking dormancy of Sorbus argentina seeds through hormone and cold stratification treatment. Background technique [0002] European Sorbus generally refers to Eurasian Sorbus. Eurasian Sorbus is a plant of Rosaceae Sorbus, a deciduous shrub or small tree; the height of the tree is 6-18 meters, the trunk is straight, the tree shape is beautiful, the crown of the young tree is oval, and the crown of the tree is spherical when mature . Odd pinnate compound leaves, 11-15 leaflets; corymbs, large and round inflorescences. The flowering period is May. Native to Europe and western Asia. Distributed in Poland, Slovenia, Belgium, the United States, Russia, Germany, Czech Republic, Hungary, Italy, Austria and other countries; China can be found in the south of Hebei, north of Shandong, central Shanxi, central Shaanxi, central Gansu, central Qinghai, and north of so...
