[0060] Example 5, wheat seed germination experiment: compound I a , I b , I c , I d and DA-6 (produced by Henan Zhengshi Chemical Co., Ltd.) to prepare 5% compound I a , I b , I c and I d Water and 5% DA-6 water were diluted with distilled water to form plant growth regulator solutions with concentrations of 10 μg / mL, 20 μg / mL, 30 μg / mL, 60 μg / mL and 120 μg / mL. Cultivate the wheat seeds with the above dilution for 8 hours, each time 100 seeds are treated, repeat 3 times each time, place the seeds in a petri dish with double-layer filter paper after treatment, keep warm at 25°C for germination, keep the filter paper moist, and observe during germination For the germination situation of each treatment, the germ length is about 1 / 2 of the seed length as the standard. After 24 hours, the germination rate of wheat in each dish is counted. The germination promotion rate of the solution is shown in Table 2 below.

Abstract

The invention discloses a beet alkaline plant growth regulator containing cinnamamide groups. The structure is shown as a general formula I. In the formula, X is selected from C1 or Br; Y is selected from H or C1; Z is selected from H or C1; M is selected from Na, K or NH4. The compound with the general formula I has excellent functions of promoting sprouting and rooting, increasing yield and improving quality, and can be widely applied to the yield increase or the survival rate increase of agriculture or forestry.

Description

technical field [0001] The invention belongs to the field of plant growth regulators in pesticides, in particular to a betaine-type plant growth regulator containing cinnamic amide groups. 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, enhancing stress resistance (disease resistance, drought resistance, salt resistance, frost resistance), enhancing the ability to absorb fertilizers, increasing sugar content or changing acidity, and improving fragrance and color have played a positive role.
