Embodiment 1

[0034] The present embodiment provides a method for cultivating a new triploid variety of Eucommia ulmoides, comprising the following steps:

[0035] a: Induction of 2n female gametes: 0.05wt% colchicine solution and 40°C high temperature treatment were applied to the female flower buds of Eucommia ulmoides female plants.

[0036] Specifically, the female flower buds are induced on the first day after the male plants of the same age start to loosen the powder. The colchicine treatment method is: drop the colchicine solution on the female flower buds until the flower buds are completely soaked, and add dropwise every half an hour. The time from the first drop to the last drop is 24 hours.

[0037] Begin to carry out high-temperature treatment while colchicine is processed, adopt tree non-isolated branch bud heating treatment device (authorization announcement number CN101057555B) to carry out, and high-temperature treatment time is 9 hours.

[0038] b: Artificial pollination: ...

Embodiment 2

[0044] The present embodiment provides a method for cultivating a new triploid variety of Eucommia ulmoides, comprising the following steps:

[0045] a: Induction of 2n female gametes: 0.25wt% colchicine solution and 46°C high temperature treatment were applied to female flower buds of Eucommia ulmoides female plants.

[0046] Specifically, the female flower buds are induced on the first day after the male plants of the same age start to loosen the powder. The colchicine treatment method is: drop the colchicine solution on the female flower buds until the flower buds are completely soaked, and add dropwise every half an hour. The time from the first drop to the last drop is 24 hours.

[0047] Begin to carry out high-temperature treatment while colchicine is processed, adopt tree non-isolated branch bud heating treatment device (authorization announcement number CN101057555B) to carry out, and high-temperature treatment time is 9 hours.

Embodiment 3

[0054] The present embodiment provides a method for cultivating a new triploid variety of Eucommia ulmoides, comprising the following steps:

[0055] a: Induction of 2n female gametes: 0.5wt% colchicine solution and 50°C high temperature treatment were applied to female flower buds of Eucommia ulmoides female plants.

[0056] Specifically, the female flower buds are induced on the first day after the male plants of the same age start to loosen the powder. The colchicine treatment method is: drop the colchicine solution on the female flower buds until the flower buds are completely soaked, and add dropwise every half an hour. The time from the first drop to the last drop is 24 hours.

[0057] Begin to carry out high-temperature treatment while colchicine is processed, adopt tree non-isolated branch bud heating treatment device (authorization announcement number CN101057555B) to carry out, and high-temperature treatment time is 9 hours.

Abstract

The invention relates to a cultivation method and development and application of a new variety of eucommia ulmoides triploid. The cultivation method comprises the following steps: a, inducing 2n female gametes: treating female flower buds on eucommia ulmoides female plant bodies by adopting 0.05-0.5 wt% colchicine solution and treating at the high temperature of 40-50 DEG C; b, artificial pollination; c, collecting seeds; d, sowing and seedling raising; e, ploidy detection; f, grafting, wherein buds with the diameter of 0.8-1 cm on the triploid plants are grafted to the diploid plants. The method has the advantage of improving the yield of the eucommia triploid.

Description

technical field [0001] The application relates to the field of polyploid breeding technology, in particular to a method for cultivating new triploid varieties of Eucommia ulmoides and its development and application. Background technique [0002] Eucommia ulmoides, also known as Bakelite, is a deciduous tree in the Eucommia family. Since ancient times, Eucommia ulmoides has been known for its dry bark as medicine. Medicinal eucommia is a precious and nourishing medicinal material in China. It is sweet in taste and warm in nature. Kidney, strengthens tendons and bones, regulates Chong and Ren, consolidates meridian and relieves miscarriage, and is used to treat lumbago and leg pain or weakness caused by kidney yang deficiency, and fetal instability caused by liver qi deficiency. It is a unique economic tree species in my country. . [0003] Plant polyploidy refers to the fact that under natural conditions, mechanical damage, ray radiation, sudden temperature changes, and other...
