Embodiment 1

[0030]1, divide the recovered cassava root into two groups: control group, treatment group 1, and treatment group 2.

[0031]Control group (normal group): After soaking of a sterile water for 2 hours, placed in a 25 ° C culture chamber, 0 hours, 2 hours, 6 hours, 12 hours, 24 hours, 48 ​​hours, and 72 hours to determine tapas. Slim fadesin content (measured 3 times each stage).

[0032]Treatment group 1: Take the cassava root with 10mm CaCl2After the solution was soaked for 2 hours, it was placed in a 25 ° C culture chamber, which was measured by a tandem flavin content in 0 hours, 2 hours, 6 hours, 12 hours, 24 hours, 48 ​​hours, and 72 hours (each stage measurement 3. Time).

[0033]Treatment group 2: Take the cassava root with 10mm CaCl2After the solution and 20 mm proline drug were soaked for 2 hours, it was placed in a 25 ° C culture chamber, which was measured by 10 hours, 2 hours, 6 hours, 12 hours, 24 hours, 48 ​​hours, and 72 hours. The content (3 times per stage) was measured.

Embodiment 2

[0037]1. Divide the recovered cassava roots into two groups: normal groups and treatment groups.

[0038]Normal group: After soaking of a sterile water for 4 hours, it was placed in a 25 ° C culture chamber, 0 hours, 2 hours, 6 hours, 12 hours, 24 hours, respectively, tattoca, roameonin. The content (3 times per stage) was measured.

[0039]Treatment group: Take the cassava root with 20mm CaCl2After the solution and 50 mm proline drug were soaked in 4 hours, it was placed in a 25 ° C culture chamber, and the oxytocoba roameon is measured at 0 hours, 2 hours, 6 hours, 12 hours, 24 hours, 48 ​​hours, and 72 hours. The content (3 times per stage) was measured.

[0040]2, the results show that the melatonin content in the normal group of oxytobat is 34.2 to 102.1 pg / g, and the melatonin content in the root of the treatment group is 49.9 ~ 187.1pg / g. Compared with the control group, the melatonin content in the root of the tuberculor potato root was significantly increased. The expression stu...

Embodiment 3

[0042]1. Divide the recovered cassava roots into two groups: normal groups and treatment groups.

[0043]Normal group: After soaking the roots of the cassava with sterile water for 6 hours, the tuber flavin is placed in the 25 ° C culture chamber, 0 hours, 2 hours, 6 hours, 12 hours, 24 hours, respectively, and 48 hours, 72 hours. The content (3 times per stage) was measured.

[0044]Treatment group: Take the cassava root with 30mm CaCl2After the solution and 100 mM of proline drug were soaked for 6 hours, it was placed in a 25 ° C culture chamber, which was measured in 0 hours, 2 hours, 6 hours, 12 hours, 24 hours, 48 ​​hours, and 72 hours. The content (3 times per stage) was measured.

[0045]2, the results show that the melatonin content in the normal group of oxytobat is 36.7 ~ 112.4pg / g, and the melatonin content in the root of the tuberculous potato is 57.9 ~ 198.6 pg / g. Compared with the control group, the melatonin content in the root of the tuberculor potato root was significant...

Abstract

The invention discloses a medicament combination that can increase the nutritional value of cassava, in particular a medicament combination that can increase the melatonin content in cassava. The present invention finds that CaCl 2 Treatment of cassava roots after harvest can not only promote the increase of melatonin content in cassava roots, but also induce the expression of melatonin synthesis pathway genes, especially CaCl 2 Combined with proline, the effect is even more significant. Therefore the present invention provides a kind of method that improves cassava root melatonin content, is to soak the cassava root after harvesting in CaCl 2 solution or CaCl 2 After being in the proline solution for a period of time, dry it and store it at room temperature. The method can significantly increase the melatonin content of the cassava root, improve the nutritional value and quality of the cassava root, and the method is safe and effective without damaging the quality of the cassava, and has wide practical application value and prospects.

Description

Technical field[0001]The present invention belongs to the technical field of crop quality improvement. More specifically, involving CACL2Application of proline in improving tama melatonin content.Background technique[0002]Melatonin is a hydrazine, an amine hormone produced by a mammalian and human pine fruit, plays an important role in delaying aging, anti-tumor, improving sleep, improve immunity, etc. In 1995, melatonin was discovered in plant tissue. At present, it is shown that melatonin has become an important nutrient component in plants, but its content is very low, it is difficult to achieve regulatory role of human health. Therefore, the regulation technology of the invention to increase the melanin content is of great significance for improving plant nutrient quality and promoting human health.[0003]Cassava is one of the three important potato crops and is the fifth largest grain crop in the world. Cassava roots contain rich nutrients, including proteins, vitamins, mineral ...
