example 1

[0012] The eustoma seeds are soaked in magnetized water containing 0.2mmol / L of salicylic acid by the above method; the magnetized water is obtained by using clean water as the water source and passing through a magnetic water heater with a magnetic induction intensity of 0.6T at a flow rate of 1m / h; The total seed soaking time is 12 hours.

example 2

[0014] The eustoma seeds are soaked in magnetized water containing 0.5mmol / L of salicylic acid by the above method; the magnetized water is obtained by using clean water as the water source and passing through a magnetic water heater with a magnetic induction intensity of 0.4T at a flow rate of 1m / h; The total seed soaking time is 14 hours.

example 3

[0016] The eustoma seeds are soaked in magnetized water containing 0.05mmol / L of salicylic acid by the above method; the magnetized water is obtained by using clean water as the water source and passing through a magnetic water heater with a magnetic induction intensity of 0.2T at a flow rate of 1m / h; The total seed soaking time is 16 hours.

[0017] The experimental method of the control group: Take 5g Lisianthus seeds (about 5000) and soak the seeds in 30℃ water for 16 hours as a control. Seed selection, seed soaking methods and seed soaking conditions are the same as those of the experimental group.

[0018] Evaluation indicators:

[0019] Count the germination potential of seeds after 7 days. Germination potential (%) = number of seeds germinated in 7 days ÷ total number of seeds × 100%

[0020] Count the germination rate of seeds after 10 days. Germination rate (%) = number of germinated seeds in 10 days ÷ total number of seeds × 100%

[0021] The dry weight of the plants was mea...

Abstract

The invention belongs to the technical field of flower culturing, especially the technical field of eustoma grandiflorum propagation. A method for accelerating germination of eustoma grandiflorum seeds is characterized by comprising the following steps of: placing the eustoma grandiflorum seeds in magnetic water containing 0.05-0.5 mmol / L of salicylic acid to soak for 2-3 hours, fetching out the seeds, drying, then placing the seeds in the magnetic water to soak for 2-3 hours, repeating the above operation 3-5 times, wherein the total soaking time is 12-16 hours; the seed soaking conditions are as follows: the temperature is 23-27 DEG C; and the illumination is 2000-2500 Lx. The method in the invention obviously accelerates germination trend and germination ratio of the eustoma grandiflorum seeds; and the complete fresh weight of the seedling is obviously larger than that of the control group. The magnetic water is added with the salicylic acid so as to accelerate the growth of the adventitious roots so that the root system is relatively developed, and the survival rate of the seedling after being transplanted is largely improved.

Description

Technical field [0001] The invention belongs to the technical field of flower cultivation, especially the technical field of eustoma propagation. Background technique [0002] Eustoma grandiflorum (Eustoma grandiflorum), also known as steppe gentian, is a one- or two-year-old taproot herb with upright stems and opposite leaves, which are oval or oblong. Flowers solitary or into panicles. Eustoma seeds are very small, about 20,000 seeds per gram, and about 1,000 seeds per gram of coated seeds. During the seedling raising period, there are specific requirements for temperature, humidity, moisture and light, so its germination rate and germination potential are low, and seedling growth is weak, which affects the survival rate after transplanting. Summary of the invention [0003] The purpose of the present invention is to provide a method for accelerating the germination of Eustoma grandiflorum seeds to improve the germination rate of the Eustoma grandiflorum seeds and the quality ...
