Abstract

PURPOSE:To provide an ultrasonic culture process to grow a growing point of a plant by ultrasonic oscillation. CONSTITUTION:An agar medium 2 is put into a vessel 1, a growing point 3 of a plant is placed on the agar medium 2, an ultrasonic oscillator 4 is attached to the bottom of the vessel 1 and an output of an oscillator 5 is applied to the ultrasonic oscillator 4. Ultrasonic oscillation is applied to the growing point 3 from the ultrasonic oscillator 4 through the agar medium 2 by the application of oscillation output to the ultrasonic oscillator 4. Since the ultrasonic wave applied to the growing point has low energy, the growing point is subjected to the ultrasonic oscillation without deteriorating the quality of the agar medium 2 and, accordingly, the growth of the growing point 3 is promoted compared with a growing point 3 free from the application of ultrasonic oscillation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic culture method for growing growing points by ultrasonic vibration.

[0002]

2. Description of the Related Art Conventionally, an agar medium has been put in a container, and flowers such as moss grass, chrysanthemum, gerbera, strawberry, asparagus, sweet potato, and orchids such as cymbidium and dendrobium have been placed on the agar medium. A method is known in which a growing point is set and the growing point is grown on this agar medium.

Further, as a method of irradiating ultrasonic waves in a method of cultivating a plant by circulating a liquid fertilizer, Japanese Utility Model Application No. 59-
No. 199317 has been proposed.

[0004]

However, in the growing point growing method, since the growing point is grown while being left on the agar medium, it takes time until the shoots come out from the growing point and the roots and leaves appear. There was a drawback that it cost.

Further, the method of cultivating plants by circulating liquid fertilizer is not suitable for growing growing points.

[0006]

[Means for Solving the Problems] The present invention provides a culture method for growing a growth point by placing the growth point on an agar medium placed in a container. It is grown by irradiation with sonic vibration.

[0007]

In the present invention, when the agar medium contained in the container is irradiated with ultrasonic waves having a small output, the ultrasonic vibration is transmitted to the growth point through the agar medium.

Since the growth point to which the ultrasonic vibration is transmitted is constantly stimulated by the ultrasonic vibration, the period during which shoots, leaves and roots emerge from the growth point is shorter than that in the state of being left unattended.

[0009]

Example 1 FIG. 1 is a diagram for explaining an ultrasonic culture method of one example of the present invention. An agar medium 2 is placed in a container 1, and a growing point 3 is placed on the agar medium 2. Has been.

Further, an ultrasonic oscillator 4 is fixedly or closely attached to the container 1, and by applying an output from an oscillator 5 to the ultrasonic oscillator 4, ultrasonic vibration is generated from the ultrasonic oscillator 4. The agar medium 2 in the container 1 is irradiated.

As described above, the ultrasonic vibration from the ultrasonic vibrator 4 is applied to the growing point 3 through the agar medium 2 to promote the growth of the growing point 3 and to grow it as compared with the one left to stand. Germination and development of roots at point 3 are very fast.

The ultrasonic vibration generated from the ultrasonic vibrator 4 may be a minute output of 0.5 mW / cm ^{2 to 1} W / cm ² , so that even if the ultrasonic vibration is continuously applied to the growing point 3, the power is not increased. Consumption is small, and since the ultrasonic output of the ultrasonic oscillator 4 is minute, the quality of the agar medium 2 is not changed and the growing point 3 is not adversely affected.

Further, as shown in FIG. 2, a container 1 containing an agar medium 2 and a growing point 3 is placed on a dish-shaped container 6, and an ultrasonic transducer 4 is placed at the bottom of the dish-shaped container 6. Even if the ultrasonic transducer 4 is provided and the agar medium 2 is irradiated with ultrasonic waves through the dish-shaped container 6 and the container 1, the growth of the growth point 3 can be promoted.

[0014]

INDUSTRIAL APPLICABILITY As described above, in the ultrasonic culture method of the present invention, the growth point is promoted by irradiating the growth point with a minute ultrasonic output from the ultrasonic vibrator through the agar medium. Moreover, since it is a micro ultrasonic vibration, there is an advantage that the quality of the agar medium is not changed.
