Abstract

The invention discloses a compound prepared based on indole-3-carboxylic acid and capable of promoting seed germination of parasitic plants, and a preparation method thereof and particularly relates to the technical field of seed germination. The structural general formula of the compound is shown in the formula (1) in the specification. In the formula, the group R is selected from at least one of 4-CH3, 5-CH3, 6-CH3, 7-CH3, 4-F, 5-F, 6-F, 7-F, 4-Cl, 5-Cl, 6-Cl, 7-Cl, 4-Br, 5-Br, 6-Br, 7-Br, 5-NO2, 4-OCH3, 5-OCH3, 5-OH, 5, 6-2F, 5-OCH2Ph, 4, 7-2Cl, 4-C2H5 and 4-OC2H5; and n is equal to 1 or 2 or 3. The compound provided by the invention has the advantage of being capable of promoting germination of striga asiatica seeds.

Description

technical field [0001] The invention relates to the technical field of seed germination, in particular to a compound capable of promoting seed germination of parasitic plants prepared based on indole-3-carboxylic acid and a preparation method thereof. Background technique [0002] Strigolactones (SLs) are a new class of plant hormones, which are a general term for natural strigol compounds and synthetic analogues. They widely exist in higher plants and are mainly synthesized in roots. With the deepening of research, many biological functions of SLs have been discovered. SLs can induce the germination of parasitic seeds, and can also play the role of signaling molecules, which can be used as branching factors of symbiotic arbuscular mycorrhizal fungi to promote the development of arbuscular fungi. Branches of symbiotic fungi. In addition, as a new type of plant growth regulator, SLs can inhibit the growth of branches and lateral buds of plants, and participate in the regulat...

Problems solved by technology

[0003] However, strigolactones and their analogs play an important role in seed dormancy and germination of parasitic plants, but due to the unstable structure of natural SLs compounds, it is difficult to mass-produce, and its analogue GR24 is expensive in the market, resulting in Limited application in seed germination of parasitic plants
