In recent years, with the deterioration of the global environment, plants have been increasingly exposed to high concentrations of salts and heavy metals, and attempts have been made to select resistant plants and to acquire resistance by genetic manipulation. However, the development of these technologies has a long time and sufficient resistant plants have not yet been created. On the other hand, if a plant damage inhibitor is developed, conventional varieties can be cultivated even in a polluted environment. Therefore, effective plant cultivation under increasingly polluted environments will be important in order to secure foodstuffs with agricultural products. In particular, there is a demand for the development of environmentally friendly disturbing agents and growth promoting agents using natural resources.

The dose of ionizing radiation is desirably in the range of 10 to 1000 kGy. The most desirable dose is about 50 to 200 kGy, depending on the type of fiber material and irradiation conditions. If the dose is too low, the decomposition effect is not obtained, and if the dose is too high, the decomposition proceeds too much and the activity is lost. For industrial production, irradiation with γ-rays from Co-60 or electron beams using an accelerator is desirable.

It may be performed after the extraction. Since the radiation processing before extraction requires a large amount of processing, it is desirable to perform large-scale processing using an electron beam having high processing capability. Radiation treatment after extraction is desirable because the amount of treatment can be significantly reduced as compared to before the extraction, but secondary effects such as improvement in extraction efficiency by irradiation cannot be expected. Therefore, it is desirable to adopt a treatment method suitable for the target fiber substance.
