Embodiment 1

[0022] Rinse the purple cabbage seeds with clean water before sowing, and then soak them in melatonin solution for 24 hours at room temperature (25°C);

[0023] Melatonin solution preparation method: Weigh 0.232g melatonin powder (purchased from sigma company, with a purity of 98%), dissolve it thoroughly in 10mL absolute ethanol, add water to 1L, and the concentration of melatonin solution at this time is 1000 μmol / L. The melatonin solution is diluted according to the required concentration of the melatonin solution, and the effective concentration of the melatonin solution is 10 μmol / L to 1000 μmol / L.

[0024] In this embodiment, four concentration treatments are set, namely 10 μmol / L, 100 μmol / L, 500 μmol / L, and 1000 μmol / L.

[0025] Rinse the soaked seeds with clean water and sow. Three replicates were set up for each treatment. Cabbage seeds soaked in water were not used as control. After the seedlings were unearthed, the color of the seedlings was observed, and samp...

Abstract

The invention relates to crop cultivation and in particular relates to a method for increasing content of anthocyanin in purple cabbage. The method for increasing the content of anthocyanin in the purple cabbage comprises the following steps: rinsing purple cabbage seeds with clear water, then soaking the purple cabbage seeds in melatonin solution for 12-24 hours at the temperature of 20-30 DEG C, washing out and then sowing. The invention provides a new method for promoting accumulation of anthocyanin in the purple cabbage, 10-1000mu mol / L melatonin solution is utilized for soaking the purple cabbage seeds, and anthocyanin content of purple cabbage seedlings can be obviously increased.

Description

technical field [0001] The invention relates to crop cultivation, in particular to a method for increasing the anthocyanin content of purple cabbage. Background technique [0002] Anthocyanin is a water-soluble plant pigment, which belongs to flavonoids and is a secondary secondary metabolite of plants. Anthocyanins have high nutritional value, regular consumption of vegetables and fruits containing anthocyanins is very beneficial to the body, it can protect the body from free radical damage, enhance immunity, and resist aging. The accumulation of anthocyanins in plants can help plants resist adversity. Anthocyanins are highly effective antioxidants that can protect plants from free radical damage. At present, there are some reports on methods for improving the accumulation of plant anthocyanins, such as utilizing L-glutamic acid to treat apples in the coloring period, which can improve the synthesis and accumulation of anthocyanins in apple peels (Wang Liangju et al., L-gl...
