Problems solved by technology

However, the content of the above three alkaloids in wild Amaryllis plants is relatively low (only a few parts per million to a few parts per million), and is also affected by provenance, developmental period and environmental conditions, and the yield is low, which is far from being able to meet Market demand
However, the cost of chemical synthesis is relatively high and the steps are complicated. At present, Lycoris alkaloids are mainly extracted from natural plants, and all plants of the genus Lycoris contain alkaloids.

Embodiment 1

[0027] Lycoris seeds (produced from the Lycoris Germplasm Resource Garden of Shanghai Academy of Agricultural Sciences) were grown in the mixed culture medium of peat, vermiculite and vermiculite, and the ratio of peat, vermiculite and perlite was 5:1:1 , water once a week during the growth process.

[0028] After one year of growth, when the bulb diameter of the plant is about 0.5 cm and the height of the plant is about 10 cm, the Lycoris plants are treated with different light quality ratios. A total of 6 different light quality treatments are set up. The common fluorescent lamp treatment is used as the control (CK). They are CK, B, RB(1:2), RB(1:1), RB(2:1) and R respectively, and the parameters of light quality conditions are shown in Table 1. The treatment conditions are as follows: the photosynthetically active radiation is 50 μmol·m -2 ·s -1 , the day / night temperature is 20°C / 15°C, the photoperiod is 12h / 12h, the plants are harvested after 30 days, and the three biol...

example 1

[0029] The light quality condition parameter described in example 1 is shown in Table 1

[0030] Table 1 Light quality parameters and test results

[0031]

[0032] Measurement results such as figure 1 As shown, the contents of GAL, LYC, and LYCM under B treatment were the highest, which were 1.84 times, 1.62 times and 1.11 times that of CK treatment, respectively. The GAL contents of RB(1:1) and RB(1:2) were 1.12 and 1.35 times that of CK, respectively, the LYC content of RB(1:2) was 1.11 times that of CK, RB(1:2) and LYCM of RB(1:1) is 1.04 times and 1.03 times of CK respectively.

[0033] Thus, B, RB (1:2), RB (1:1) can promote the accumulation of GAL, LYC and LYCM in Lycoris seedlings to different degrees, and the induction effect of B treatment is the best for 30 days.

Embodiment 2

[0035] Lycoris seeds (produced from the Lycoris Germplasm Resource Garden of Shanghai Academy of Agricultural Sciences) were grown in the mixed culture medium of peat, vermiculite and vermiculite, and the ratio of peat, vermiculite and perlite was 5:1:1 , water once a week during the growth process.

[0036] After one year of growth, when the bulb diameter of the plant is about 0.5 cm and the height of the plant is about 10 cm, the Lycoris plants are treated with different light quality ratios. A total of 6 different light quality treatments are set up. The common fluorescent lamp treatment is used as the control (CK). They are CK, B, RB(1:2), RB(1:1), RB(2:1) and R respectively, and the light quality condition parameters are the same as in Table 1. The treatment conditions are as follows: the photosynthetically active radiation is 50 μmol·m -2 ·s -1 , the day / night temperature is 20°C / 15°C, the photoperiod is 12h / 12h, the plants are harvested after 14 days, and the three bi...

Abstract

The invention provides a cultivation method of lycoris plants. The method comprises the following steps that LED light quality is used for treating lycoris plant seedlings, wherein the LED light quality is blue light (B) or red and blue compound light (RB). The content of alkaloid type ingredients of galanthamine, dihydrogalanthamine and lycorine in the lycoris plants cultivated by the method is obviously improved; the operation of the method is simple and convenient; the production period is short; the method is applicable to factory production; important significance is realized for meetingthe industrialized production of lycoris anticancer alkaloid.

Description

technical field [0001] The invention relates to the field of plant cultivation, in particular to a method for cultivating Lycoris plants. Background technique [0002] Lycoris spp. is a bulbous herbaceous plant of Amaryllidaceae (Amarylllidaceae), with high ornamental value, and it is a good material for flower borders and understory ground cover. At the same time, it also has medicinal functions, and is rich in alkaloid components unique to a variety of Amaryllidaceae plants. Lycorine (LYC) can induce the apoptosis of the cancer cell line HL-60, galantamine (GAL) and ricolamine (LYCM), which are one of the first-choice drugs for the clinical treatment of Alzheimer's disease. However, the content of the above three alkaloids in wild Amaryllis plants is relatively low (only a few parts per million to a few parts per million), and is also affected by provenance, developmental period and environmental conditions, and the yield is low, which is far from being able to meet Mark...
