Problems solved by technology

However, these compounds are complicated to synthesize on the one hand, more expensive, and inconvenient to use
For example, 3-indoleacetic acid is unstable and easy to decompose when exposed to light. At the same time, it will be rapidly oxidized and decomposed by indoleacetic acid oxidase in plants and inactivated; 3-indolebutyric acid is more stable than indoleacetic acid, but its water solubility is poor; Compared with 3-indolebutyric acid, naphthaleneacetic acid has certain toxicity, and it is easy to damage plants if the concentration is too high

Embodiment 1

[0019] Example 1: Synthesis of N,N-piperidinyl-2-(benzaldoximeoxy)ethylamine (compound 1c)

[0020] Add 6.7 g (0.05 mol) of benzaldehyde oxime, 2.4 g (0.06 mol) of sodium hydroxide and 15.0 mL of water into a dry 100 mL two-necked flask. Adjust the temperature to 50°C and stir to dissolve for 30 min, then add dropwise a solution of 11.0 g (0.06 mol) N-(2-chloroethyl)piperidine hydrochloride and 15.0 mL of water for 30 min. After the dropwise addition, adjust the temperature to 100 °C and continue the reaction for 8 h. At this time, the reaction solution clearly separated, cooled, and the organic phase was separated. The aqueous layer was extracted with anhydrous ether (3×20.0 mL), and the organic phases were combined, washed with water, and dried. , the solvent was evaporated under normal pressure to obtain a dark brown liquid, which was passed through a silica gel column with mobile phases of ethyl acetate and methanol to obtain the target product with a yield of 48.2%. The ...

Abstract

The invention discloses an oxime ether amine compound or oxime ether amine salt, a composition containing oxime ether amine compound or oxime ether amine salt and application thereof. The oxime ether amine compound or the oxime ether amine salt is provided with a structure general formula as a general formula (1) or a general formula (2). The invention also discloses one composition containing the oxime ether amine compound or the oxime ether amine salt or an auxin plants growth promoter. The invention further discloses the application of the oxime ether amine compound or the oxime ether amine salt or the composition containing the oxime ether amine compound or the oxime ether amine salt. Since the oxime ether amine compound or the oxime ether amine salt or the composition containing the oxime ether amine compound or the oxime ether amine salt is provided with obvious cutting root growth activity, number, average length or height of adventitious roots of cuttings are greatly promoted, and action concentration is quite wide in range.

Description

technical field [0001] The present invention relates to a compound having a growth regulating effect on plants, in particular to an oxime ether amine compound or a salt thereof, a composition containing the oxime ether amine compound or a salt thereof and the application thereof as a plant rooting accelerator. Background technique [0002] Garden engineers often use cuttings to propagate trees, fruit trees and flowers in large quantities. Cutting propagation can maintain the excellent traits of the mother and shorten the breeding cycle. The formation of adventitious roots in the cutting propagation process of plants is the key to the success or failure of cuttings. Plant rooting accelerators play a vital role in the formation of adventitious roots. The rooting rate of cuttings treated with rooting accelerators, transplanting survival rate, Seedling height and ground diameter have generally increased. At present, the common rooting promoters are mainly auxins, such as 3-ind...
