Definitions
- the present invention relates to a method for imparting resistance to stress to plants. More particularly, the present invention relates to a method of imparting to plants resistance to biological, physical or chemical stress that affects plant growth.
- Plants grown in farmland or ordinary households are always exposed to various biological and abiotic stresses. Cultivated crops generally tend to be less resistant to these stresses. Agricultural chemicals such as bactericides, insecticides and herbicides are used to reduce biological stress such as pests and weeds and maintain yield. However, the effects of pesticides are insufficient, if they are used incorrectly, they cause phytotoxicity, pests and weeds develop resistance to pesticides, and there are concerns about the safety of environmental organisms. In addition, environmental stresses such as temperature, moisture, illuminance, soil pH, and salt concentration are dealt with by appropriate cultivation, breeding improvement, irrigation, greenhouse and soil improvement. Attempts to impart stress resistance with plant growth regulators have been made, but the effect is not sufficient. In addition, plant viral diseases cause serious damage to important crops such as cereals, vegetables and fruit trees. However, until now no drug has been found that sufficiently exerts a practical effect on plant viral diseases.
- Non-Patent Document 1 reports that ascorbic acid is involved in disease resistance, hormonal action, etc.
- Non-Patent Document 2 reports that ascorbic acid affects plant aging.
- ascorbic acid is present in a high concentration in the plant body, even if ascorbic acid is given to the plant from the outside, its physiological influence is slight and there is almost no practical effect.
- Patent Document 1 proposes that certain derivatives of ascorbic acid are applied to plants as having a preventive and therapeutic effect on viral diseases of plants.
- Patent Document 2 discloses a composition containing an antibacterial antibiotic such as neomycin sulfate and ascorbic acid, and states that plant diseases can be suppressed by this composition.
