Embodiment 1

[0022] The significant effect of brucetin D on the seed germination and growth of the monocotyledonous wild oat (Avena fatua L.) was screened from its pure product in different concentration aqueous solutions.

[0023] 1. Preparation of Bruceabrucein D pure product solution

[0024] Prepare 7 concentrations of brucein D aqueous solutions, respectively 6.25 μg / mL, 12.5 μg / mL, 25 μg / mL, 50 μg / mL, 100 μg / mL, 200 μg / mL, 400 μg / mL, and clean water was used as the blank control.

[0025] 2. Wild oat seed treatment

[0026] Select wild oat seeds with the same size and full grains, soak them in 2.5% NaClO solution, and stir them with a magnetic stirrer for 10 minutes, then wash them with sterile water for 3 times (3 minutes each time), dry them with absorbent paper, and store them at 25°C. Under the germination for 24 hours, the wild oat seeds with the same dew and white color were selected for determination.

[0027] Spread double layers of filter paper in a glass Petri dish (diame...

Embodiment 2

[0043] The significant effect of Brucella D on seed germination and growth of spontaneous rape (Brassica napus L.) was screened from its pure product in different concentration aqueous solutions.

[0044] 1. Preparation of Bruceabrucein D pure product solution

[0045] Prepare brucein D aqueous solution with 7 concentrations. They were 6.25 μg / mL, 12.5 μg / mL, 25 μg / mL, 50 μg / mL, 100 μg / mL, 200 μg / mL, 400 μg / mL, and clear water was used as the blank control.

[0046] 2. Rapeseed seed treatment

[0047] Select wild oat seeds with the same size and full grains, soak them in 2.5% NaClO solution, stir them with a magnetic stirrer for 10 minutes, then wash them with sterile water for 3 times (3 minutes each time), blot them dry with absorbent paper, and store them at 25°C. Next germination 24h. Pick wild oat seeds with consistent dew and white color for determination.

[0048] Spread double layers of filter paper in a glass Petri dish (diameter 9 cm) after autoclaving, and add p...

Abstract

The invention belongs to the field of plant-derived herbicidal active matters and particularly relates to application of the compound bruceine D in inhibiting the germination and growth of herbicidal seeds. The compound has a molecular structural formula shown as in the general formula (I). By comparing the influences of bruceine of different concentrations upon the germination and growth of wild oat and autogenic rape, it is discovered that the bruceine D has significant inhibitory action to seed germination and growth for the monocotyledonous weed Avena fatua L. and the dicotylous weed Brassica napus L. Bruceine D solution just 200 Mug / mL can completely inhibit the seed germination of the dicotylous weed Brassica napus L. Bruceine D has a promising application prospect in terms of weed control.

Description

technical field [0001] The invention belongs to the field of research on herbicidal active substances of botanical origin, and in particular relates to the application of the compound brucein D to inhibit the germination and growth of weed seeds. Background technique [0002] Weeds compete with crops for light, water, fertilizer and other resources and become an important factor affecting crop yield and quality. For a long time, chemical herbicides have been mainly used to control the damage of weeds. However, food safety, The adverse effects on public health, natural environment and weed resistance (resistance) have attracted people's attention day by day. [0003] The widespread use of chemical pesticides has played a huge role in ensuring high and stable yields of crops. However, the long-term use of traditional chemical pesticides has led to the resistance of pests, forcing people to increase the dosage of pesticides, which has caused more and more serious environmental ...
