Abstract
The invention provides a method for promoting selfing fructification of sweet potatoes, which belongs to the technical field of crop germplasm innovation and new variety breeding and comprises the following steps: spraying quercetin during the flowering period of the sweet potatoes. In the invention, the quercetin can improve the self-compatibility of the sweet potatoes by inhibiting the activity of protein kinase, promote the self-fructification of the sweet potatoes and improve the fructification rate of the sweet potatoes.
Description
Technical Field
The invention belongs to the technical field of crop germplasm innovation and new variety breeding, and particularly relates to a method for promoting selfing fructification of sweet potatoes.
Background
The sweet potatoes originate from south America and belong to short-day plants, many varieties cannot naturally bloom in the north of 23 degrees in northern latitude, and buds can bloom after being grafted, subjected to short-day treatment and the like. The sweet potato is a cross-pollinated plant, self-incompatibility exists, and a cross-breeding infertility group exists, which seriously restricts the development of sweet potato breeding work. Inbred can create a breeding material with gene homozygous, pure line hybridization can generate stronger heterosis, the inbred line is applied to various field crops such as corn and the like at present and obtains better effect, but research shows that the inbred compatible variety of the sweet potato is less than 10 percent, and the inbred maturing rate of the sweet potato is difficult to improve all the time, thereby influencing the improvement of the sweet potato variety.
Disclosure of Invention
In view of the above, the invention aims to provide a method for promoting sweet potato selfing fructification.
In order to achieve the above purpose, the invention provides the following technical scheme:
the invention provides a method for promoting selfing fructification of sweet potatoes, which comprises the following steps: spraying quercetin during the flowering period of the sweet potatoes.
Preferably, the quercetin is dissolved in acetic acid and then mixed with water to obtain a quercetin solution, and the quercetin solution is sprayed on the sweet potatoes.
Preferably, the concentration of quercetin in the quercetin solution is 1500 μmol/L.
Preferably, the quercetin solution is sprayed for 1 time every 3-4 days.
Preferably, the variety of the sweet potato comprises Xupurple sweet potato No. 8.
The invention provides a method for promoting selfing fructification of sweet potatoes, which comprises the following steps: spraying quercetin during the flowering period of the sweet potatoes. In the invention, the quercetin can improve the self-compatibility of the sweet potatoes by inhibiting the activity of protein kinase, and promote the self-fructification of the sweet potatoes.
Detailed Description
The invention provides a method for promoting selfing fructification of sweet potatoes, which comprises the following steps: spraying quercetin during the flowering period of the sweet potatoes.
The invention preferably dissolves the quercetin in acetic acid, then mixes the quercetin with water to obtain a quercetin solution, and sprays the quercetin solution on the sweet potato. In the present invention, the concentration of quercetin in the quercetin solution is preferably 1500. mu. mol/L. In the invention, the quercetin solution is preferably sprayed for 1 time every 3-4 days. In the invention, the variety of the sweet potato preferably comprises Xu purple sweet potato No. 8.
The technical solutions provided by the present invention are described in detail below with reference to examples, but they should not be construed as limiting the scope of the present invention.
Example 1
Dissolving quercetin in acetic acid, and mixing with water to obtain quercetin solution with quercetin concentration of 1500 μmol/L. Spraying the quercetin solution in the blooming period of the slow purple sweet potato No. 8, spraying for 1 time every 3-4 days, spraying 8 plants in total, and treating for 30 days to obtain 220 selfing seeds in total.
Comparative example 1
The quercetin solution was replaced with clean water as a control, and the conditions were the same as in example 1, but no selfed seeds were obtained.
According to the embodiment and the comparative example, the method provided by the invention improves the selfing setting rate of the sweet potatoes.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
Claims (5)
1. A method for promoting self-fructification of sweet potatoes is characterized by comprising the following steps: spraying quercetin during the flowering period of the sweet potatoes.
2. The method according to claim 1, wherein the quercetin is dissolved in acetic acid and then mixed with water to obtain a quercetin solution, and the quercetin solution is sprayed onto the sweet potato.
3. The method of claim 2, wherein the concentration of quercetin in the quercetin solution is 1500 μmol/L.
4. The method according to claim 2, wherein the quercetin solution is sprayed 1 time every 3-4 days.
5. The method of claim 1, wherein the variety of sweet potato comprises xu purple sweet potato # 8.
