Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the seeds of Cyclocarya paliurus can only germinate every other year under natural conditions, and the germination rate is low. The goal of collecting seeds in the same year and sowing seedlings in the next year is to solve the technical problems of Cyclocarya paliurus seedlings

Embodiment 1

[0015] 1. Seed collection: Collect mature Cyclocarya paliurus seeds for 2012.

[0016] 2. Seed treatment:

[0017] (1) After the seeds are harvested, remove the wings, grind the seeds on the rough concrete floor with coarse sandpaper and a wooden trowel, and grind off most of the outer skin.

[0018] (2) Soak the peeled seeds in clean water, add washing powder and rub the peel 6 times, soak and disinfect the seeds with 50ppm potassium permanganate solution for 0.5 hours, wash and dry in the shade.

[0019] (3) Use low-warm-low variable temperature stratification combined with plant growth regulator (gibberellin) treatment to release dormancy technology, and perform germination treatment. The specific method is: soak the Cyclocarya paliurus seeds treated in step (2) in clear water for 4 days, filter and dry, soak for 24 hours with 400ppm gibberellin solution, then mix evenly with wet sand soaked with 400ppm gibberellin, Put it into a plastic storage box, and put it in a 4°C r...

Embodiment 2

[0024] 1. Seed collection: Collect mature Cyclocarya paliurus seeds for 2013.

[0025] 2. Seed treatment:

[0026] (1) After the seeds are harvested, remove the wings, grind the seeds on the rough concrete floor with coarse sandpaper and a wooden trowel, and grind off most of the outer skin.

[0027] (2) Soak the peeled seeds in clean water, add washing powder and rub the peel 8 times, soak the seeds in 50ppm potassium permanganate solution for 0.5 hours, wash and dry in the shade.

[0028] (3) Use low-warm-low variable temperature stratification combined with plant growth regulator (gibberellin) treatment to release dormancy technology, and perform germination treatment. The specific method is: soak the Cyclocarya paliurus seeds treated in step (2) in clear water for 5 days, filter and dry, soak with 400ppm gibberellin solution for 24 hours, then mix evenly with wet sand soaked with 400ppm gibberellin, Put it into a plastic storage box, and put it in a 2°C refrigerator for ...

Abstract

The invention discloses a cyclocarya paliurus seed treatment method and belongs to the field of tree reproduction. The method includes the steps: (1) collecting seeds, removing fruiting wings and grinding thin seed coats with a mechanical method; (2) rubbing and elutriating the seeds in clear water added with alkaline synthetic detergent for six to eight times for removing part of inhibitors in the seed coats; (3) adopting the low-warm-low temperature-variable stratification and plant growth regulator (gibberellin) treatment combined dormancy release technique for accelerating germination. Inhibition of cyclocarya paliurus seed germination is eliminated or alleviated by the above taken measures, germination of the cyclocarya paliurus seeds is accelerated and increased, and high germination rate of 78.1-82.6% is obtained. By the technique, the seeds harvested in the current year can be sowed for seedling raising in the next spring.

Description

technical field [0001] The invention belongs to the field of tree propagation, in particular, it provides a treatment method for Cyclocarya paliurus seeds. Background technique [0002] Cyclocarya papaya ( Cyclocarya paliurus (Batal) Iljinskaja) is a rare and protected plant unique to my country. Cyclocarya paliurus contains polysaccharides, triterpenoids, steroids, flavonoids and other compounds, which have various functions such as lowering blood sugar and blood lipids, anti-tumor and anti-aging. It is a good natural health food and medicinal resource, and it is a precious tree species with great development prospects. The seeds of Cyclocarya paliurus have deep dormancy characteristics. After conventional sowing, they will germinate every other year or even 2 years later, and the natural germination rate is extremely low (less than 0.2%). The survey found that in the distribution area of ​​Cyclocarya paliurus, due to the low germination rate of seeds, Its natural regener...
