example 1

[0019] Example 1, the preparation of formula I compound

[0020] (1) Preparation of Naphthalene Acetyl Chloride

[0021]

[0022] Add 18.6g (0.1mol) of naphthalene acetic acid and 100mL of toluene to a 250mL three-necked flask respectively, and dropwise add a solution composed of 17.9g (0.15mol) of thionyl chloride and 30mL of toluene. The solvent dichloromethane and thionyl chloride were distilled off to obtain 19.4 g of light yellow oily liquid with a yield of 94.6%.

[0023] (2) preparation of formula II compound

[0024]

[0025] 15.5g (0.1mol) of 6-chloropurine and 6.1g (0.1mol) of ethanolamine were added to a 250mL three-necked flask, and 100mL of ethanol was used as a solvent, heated to reflux, stirred and reacted for 3.5h, after the reaction was complete, cooled, and suction filtered to obtain light The yellow-green solid was dried to obtain 15.6 g, and the yield was 87.1%.

[0026] (3) preparation of formula I compound

[0027]

[0028] Add 17.9g (0.1mol)...

example 2、10

[0031] The preparation of example 2,10% formula I compound suspending agent:

[0032] Take by weighing 15g formula I compound, 2g sodium lignosulfonate, 3g polycarboxylate dispersant Sokalan CP 5 (maleic acid-acrylic acid sodium salt), 1g organosilicon milk defoamer (THIX-108 water-based silicon emulsification defoamer foaming agent), 2g magnesium aluminum silicate and 5g ethylene glycol in a 250mL beaker, add 77g water, stir evenly, grind with a sand mill for 2 hours, the speed is 3000 rpm, and the particle size is 3-5μm, and white fluidity is obtained. suspending agent.

[0033] Bioactivity assay

example 2

[0034] Example 2, seed germination experiment

[0035] The paper bed germination method was adopted. Dilute 30% formula I compound suspending agent, DA-6, 6-BA into 5% formula I compound suspending agent, 5% DA-6 aqueous agent, 5% 6-BA suspending agent, dilute with distilled water respectively to concentration 10 μg / mL, 20 μg / mL, 30 μg / mL, 60 μg / mL and 120 μg / mL plant growth regulator solutions. Select wheat seeds with uniform grain size and plumpness, sterilize the seeds with hypochlorous acid solution, soak the seeds in the beaker with the above dilution solution for 8 hours, and repeat 3 times for each treatment of 100 seeds. In the petri dish with double-layer filter paper, keep a certain distance between the seeds. After placing the seeds, put them in a fully intelligent climate box at 25°C for heat preservation and germination treatment. During the period, distilled water should be added regularly to keep the filter paper moist. The germination situation of the treatme...

Abstract

The invention discloses a 6-aminopurine ethyl-naphthylacetic acid ester compound which serves as a plant growth regulator. The compound shown as the formula I has excellent effects of promoting germination and rooting, increasing the yield and improving the quality and can be widely used for increasing the yield or improving the survival rate in agriculture or forestry.

Description

technical field [0001] The invention belongs to the field of plant growth regulators in pesticides, and in particular relates to a 6-aminopurine ethylnaphthalene acetate compound and its application as a plant growth regulator. Background technique [0002] Plant growth regulators are used in controlling seed germination and dormancy, promoting rooting, promoting cell elongation and division, controlling lateral buds or tillers, controlling plant type, controlling flowering, inducing seedless fruit, thinning flowers and fruit, controlling fruit drop, controlling fruit shape or In the mature stage, it plays a positive role in enhancing stress resistance (disease resistance, drought resistance, salt resistance, frost resistance), increasing nutritional content, improving fruit color and taste, and enhancing the ability to absorb fertilizers. [0003] α-Methyl naphthalene acetate is a plant growth regulator with auxin activity, mainly used for potato bud suppression, wheat bud ...
