Steps of improving germination rate of drunken butterfly flower seeds

Preparation steps

First, wash the seeds of drunken butterfly flower with clean water and remove impurities, then put them into the tray with filter paper, and seal and wrap the tray with plastic film

Dark cultivation steps

Place the wrapped tray in low temperature and dark environment for about 10-12 hours

Light culture steps

After taking out the tray, place it at a temperature of about 20-25 ℃ and incubate in an environment with appropriate light for 12-14 hours

Seeding and culture steps

Repeat the above two steps of dark culture and light culture alternately until the radicle of the seed is white, the seed can be sown or sown in the sowing soil, watered, placed at a temperature of about 20-25 ℃ and cultured in an appropriate amount of light for 3 or 4 days, and the seed can germinate

Through the above treatment, the seeds are alternately placed in the culture environment of darkness plus low temperature and light plus relatively high temperature, and the seeds of drunken butterfly flower are kept wet, so as to promote the repeated reduction and expansion of the seed coat, resulting in the rupture and water absorption of the seed coat, so as to effectively promote the seed germination, and the germination rate is very high< span>
