Embodiment Construction

[0022] The substantive content of the present invention will be specifically described below in conjunction with the embodiments, but those skilled in the art should know that the protection scope of the present invention should not be limited to these specific embodiments.

[0023] 1. Experimental materials

[0024] Galantamine, epigalantamine, Lycosinine A, Lycosinine B, manjuline, lycorine, dihydrolycorine, narciscine purchased or homemade, with a purity of not less than 95%. The chemical structural formula is shown in the table below.

[0025]

[0026] 2. Experimental method

[0027] 1. Planting of cassava seedlings

[0028] The cassava SC8 variety (namely Huanan No. 8, sensitive to drought) with a diameter of about 2 cm and a length of about 10 cm was used to plant in a plastic flowerpot with a diameter of 26 cm, a bottom diameter of 16 cm, and a height of 23 cm. Fill the pot with sun-dried vermiculite and sand at a ratio of 1:1 (V:V). Weigh the flower pot (W1) in ...

Abstract

The invention discloses application of a cassava MeTPS1-3 gene expression activator in preparing a fertilizer for enhancing drought resistance of cassava. It is known that the cassava stressfully increases the expression of MeTPS1-3 under drought conditions to improve resistance to drought stress. According to the application, the expression of the MeTPS1-3 is significantly improved after the intervention of lycorisin and sekisanine, and the resistance to the drought stress is significantly enhanced. Therefore, the lycorisin and the sekisanine can be used for preparing a fertilizer for improving the drought resistance of the cassava. The fertilizer may also be added with a fertilizer additive or a fertilizer auxiliary material, the fertilizer additive may be human and animal excreta, and the fertilizer auxiliary material may be fly ash, plant ash, bentonite, kaolin, attapulgite clay or plant straw.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to the application of a cassava MeTPS1-3 gene expression activator in preparing fertilizers for enhancing the drought resistance of cassava. Background technique [0002] Cassava (Manihot esculenta Crantz) is recognized as an economic crop with high comprehensive utilization value and an important industrial raw material. Cassava suffers from long-term drought, especially at the seedling stage, which will lead to a sharp decline in cassava yield. Studying the molecular mechanism of cassava drought resistance can not only improve the drought resistance of cassava varieties, but also provide a reference for the drought resistance research of other crops. [0003] In recent years, in the study of plant stress resistance, trehalose synthase gene is another kind of gene closely related to stress resistance after glutamic acid, proline, and betaine synthase genes, which has aroused...
