Problems solved by technology

[0003] During the long-term evolution, the plants of the genus Ginseng have been highly adapted to the low temperature conditions in high-altitude areas. They are introduced to low-altitude areas by conventional methods such as perennial root or seed propagation, and often die because they cannot adapt to high temperatures exceeding 30°C in summer; moreover, The introduced plants are unable to carry out natural sexual reproduction due to the lack of insects in the original place for auxiliary pollination.

Embodiment 1

[0022] Example 1: Artificial assisted pollination method of early-flowered ivory ginseng is as follows:

[0023] (1) During the full flowering period (May to July) of potted early-flowered ivory ginseng, at noon on the day of the opening of the small flowers in the spike-like inflorescence (inflorescence stem exposed), the small flowers that bloom in the lower part of the panicle-like inflorescence that open on the same day and perform strong performance are initially selected as the objects of artificial pollination. Figure 1 A；

[0024] (2) After slightly folding the 3 corolla lobes of the small flowers, the pistils and stamens inside are exposed, and the flowers that have matured and have just begun to disperse are selected, Figure 1 B；

[0025] (3) Carefully pick out the extremely delicate pistil flower pillar from the filigree groove of the stamens with sharp forceps, clamp the anther septum that extends to the base of the stamens into a distance, avoid the flower pillars of ...

Embodiment 2

[0029] Example 2: The artificial hybrid pollination method of sessile ivory ginseng is as follows:

[0030] (1) At the peak flowering period (July) of potted sessile ivory ginseng, at noon on the day of the opening of small flowers in the spike-shaped inflorescence (inflorescence stem exposed), the small flowers that bloom in the middle and lower parts of the inflorescence that bloom on the same day and perform strong performance are initially selected as the mother of artificial hybrid pollination. Figure 2 A；

[0031] (2) After slightly folding the 3 corolla lobes of the sessile ivory ginseng florets, the pistils and stamens inside are exposed, and the stamens anthers are selected to mature and have just begun to disperse and the lower bending column head has not touched the pollen flowers. Figure 2 B；

[0032] (3) Carefully pick out the extremely slender pistil flower pillar of sessile ivory ginseng from the stamens filigree groove with sharp forceps, clamp the anther septum at...

Embodiment 3

[0036] Example 3: Artificial hybrid pollination method of powder leaf ivory ginseng, comprising the following steps:

[0037] (1) At the peak flowering period (July) of the potted powder leaf ivory ginseng, at the noon of the opening day of the small flowers in the panicle-shaped inflorescence (inflorescence peduncle exposed), the small flowers that bloom in the lower part of the inflorescence that bloom on the same day and perform strong performance are initially selected as the mother of artificial hybrid pollination. Figure 3 A；

[0038] (2) After slightly inverting the 3 corolla lobes of the pink leaf ivory ginseng florets, the pistils and stamens inside are exposed, and the flowers with stamens anthers are mature and have just begun to disperse, Figure 3 B；

[0039] (3) Carefully pick out the extremely delicate pistil flower column from the stamen filigree groove with sharp forceps, clamp the anther partition at the base of the stamens extending into a distance, avoid the pis...

Abstract

The invention discloses a method for artificial pollination of plants belonging to the genus Ivory Ginseng. The method is to fold back the three lobes of the corolla slightly in the blooming stage of the plants of the genus Ivory Ginseng, and use sharp tweezers to clamp the base of the stamens and extend them into spurs. Anther septum, gently remove the entire anther; clamp the entire anther directly, gently apply the pollen to the pistil stigma of the emasculated female flower several times, and then restore the three corolla lobes to complete the growth of the genus Ginseng Artificial pollination; the method of the present invention is simple, efficient, and low in cost, can effectively improve the pollination rate and fruit setting rate of selfing or hybridization of plants of the genus Ivory Ginseng, and is beneficial to carry out self-breeding or hybridization of plants of the genus Ivory Ginseng. Promotion and use.

Description

Technical field [0001] The present invention belongs to the field of biotechnology, specifically relates to a method of artificial pollination of ivory ginseng plants. Background [0002] Roscoea Smith is a perennial, low-rise herb of the Ginger family with thick, swollen fleshy roots that resemble ivory. Found only in the Himalayas, the genus is one of the few group of species in the Zingiberaceae family that is distributed at high altitudes. Its many species are often used as Tibetan medicine and folk herbs in southwest China, with the effect of dissipating cold in temperature, relieving pain and eliminating food; The flowers are large and beautiful, and they can be admired and have important economic value. Ivory ginseng plants are spike-like inflorescences or head-shaped inflorescences, the structure of the florets is more unique, there are 3 corolla lobes, one lobe in the rear is upright, larger, pocket-shaped, and the lobes on both sides are narrower, flattened or bent; The...
