Seed soaking agent for promoting germination of Folium Cylocaryae Paliuri seeds

Abstract

The invention discloses a seed soaking agent for promoting the germination of Folium Cylocaryae Paliuri seeds, and belongs to the tree breeding field. The seed soaking agent is characterized in that the liquid seed soaking agent is prepared by adding 0.6g of NaCl, 0.98g of KCl, 0.17g of CaCl2.2H2O, 0.11g of MgCl2.6H2O, 30-40mg of poly(ethyleneglycol)alkylmethacrylate, 40mg of gamma-aminobutyric acid and 0.2g of astaxanthin to 1000ml of distilled water. Compared with seed soaking agents in the prior art, the seed soaking agent in the invention can promote the germination of the Folium Cylocaryae Paliuri seeds, so a high germination percentage is obtained, and a high seedling survival rate can be obtained at a low temperature.

Description

Technical field [0001] The present invention relates to a seed soaking agent, in particular to a seed soaking agent for promoting the germination of Cyclocarya paliurus seeds, which can be used for low-temperature environment cultivation and the germination of new seeds. Background technique [0002] Cyclocarya paliurus Iljin. (Cyclocarya paliurus Iljin.) is a unique single-species tree plant in my country. It is one of the endangered plants under national key protection and belongs to three types of protected plants. The green willow tree species has a wide range of uses and is a precious tree species with great development and development prospects. Studies have found that Cymbidium morifolium leaves not only contain macro elements such as potassium, calcium, magnesium, and phosphorus, which are necessary for the human body, but also trace elements that are important for human health, such as manganese, iron, copper, zinc, selenium, chromium, and alum. , Germanium, etc.; Cyclo...

Problems solved by technology

However, the above scheme still has the following defects: ① GA 3 (Gibberellin) is the most widely used plant growth regulator in agriculture, forestry and horticulture in my country. It is mainly used to promote the growth and development of crops, mature early, increase yield and break the dormancy of seeds, tubers, bulbs and other organs. , but the main function of gibberellin is to promote cell elongation, thereby causing stem elongation and plant height, when using GA 3 If there are unfavorable climatic conditions such as drought, due to GA 3 The overgrowth brought about will aggravate the injury of the seedlings and cause the death of the seedlings. The above reasons limit the application of Cyclocarya paliurus seeds, and are only limited to the field of laboratory research; Problems such as difficulty in effectively and substantially improving the genetics, breeding, and production of Cyclocarya paliurus are limited; ③ Cyclocarya paliurus is mainly distributed in Anhui, Jiangsu, Zhejiang, Jiangxi, Fujian and other places, and there is no growth in Shandong, and the reason is mostly due to Germination and seedling stages, seed germination and early seedling growth are sensitive periods to adversity, with low resistance

However, if the temperature of germination and seedling growth is accommodated and the sowing is postponed until mid-April when the temperature is suitable, the height of the seedlings has not reached 10cm, and it has entered summer at this time, with high temperature and hot weather, accompanied by summer drought, low air humidity, and groundwater. The position is high and the soil drainage performance is poor, which will easily cause the seedlings to fail to survive the summer and lead to death. Even if the seedlings are treated with shade, the seedlings will survive safely, but the growth will be slow or even stagnant
