JP2001122706A - Agent for applying to leaf surface of flowering plant - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide an agent which is applied to the leaf surfaces of flowering plants, and has excellent effects for preventing the leaf scorches of lily and chrysanthemum and for preventing the withering of chrysanthemum, perennial Gypssphila elegans, delphinium and so on, just after cut into herbaceous cuttings. SOLUTION: This agent for applying to flowering plant leaf surfaces contains one or more kinds of fatty acids. The fatty acids are especially not limited, but are preferably >=8C fatty acids which are liquid at the ordinary temperature, such as oleic acid, because the fatty acids can easily be formulated. The form of the formulation is a formulation obtained by dissolving the fatty acid in an organic solvent or a formulation obtained by dispersing or dissolving the fatty acid in water. The agent may contain a nonionic surfactant to enhance adhesivity to the leaf surfaces.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention significantly improves the quality of cut flowers by preventing leaf burning, which is a physiological injury to chrysanthemums and lilies, and preventing cutting and buds and wilting which hinders growth immediately after planting. The present invention relates to a flower leaf applying agent.

[0002]

2. Description of the Related Art Leaf scorch is a physiological disorder that is a major problem in the cultivation of lilies, especially Asiantic hybrids and Oriental hybrids. 3 flower stems
Occurs when it reaches 0-40 cm. Symptoms are white spots appearing from the top of the young leaves, and in severe cases, the leaves and flower buds of the tips turn brown and stop growing. Although measures to mitigate rapid growth, avoid sudden changes in temperature and humidity, and avoid high humidity have been mentioned as mitigation measures, they could not be completely prevented. In the cultivation of chrysanthemum, cuttings and withering immediately after planting remarkably hinder growth. Similar phenomena are also seen in Delphineum, a habitat that is increased by cuttings.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a flower leaf surface which has an excellent effect on the prevention of burning of lily and chrysanthemum leaves and the prevention of wilting of chrysanthemums, hedgegrass grass, delphinium, etc. immediately after cutting. To provide an application agent.

[0004]

The flower leaf applying agent of the present invention is characterized by containing one or more fatty acids.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The fatty acid used in the present invention is not particularly limited, but a fatty acid having 8 or more carbon atoms and being liquid at ordinary temperature, for example, oleic acid, is preferable in terms of easy preparation. The form of the fatty acid may be a normal saturated fatty acid, a normal mono-unsaturated fatty acid, a normal di-unsaturated fatty acid, or a normal tri-unsaturated fatty acid. These isoforms having a branch may be used.

[0006] The preparation form of the product of the present invention is one in which fatty acids are dissolved in an organic solvent, or one in which fatty acids are dispersed or dissolved in water. Examples of the organic solvent include ethanol, acetone, and ethylene glycol.
Further, a nonionic surfactant may be contained in order to enhance the adhesion to the leaf surface. Examples of the nonionic surfactant include polyoxyethylene sorbitan fatty acid ester.

When the product of the present invention is applied to a plant, it is preferable to spray the diluent on the plant using a spraying device, but the diluent may be applied with a brush or the like.

[0008]

[Comparative Example 1] When buds of Lily of the Butterfly began to be seen, only water was sprayed three times every five days. The incidence of leaf burning at the time of shipment was 80%.

[0009]

[Example 1] Table 1
No. Composition 1 was diluted 1500 times with water and sprayed three times every five days. The incidence of leaf burning at the time of shipment was 2%. Leaf scorch can be prevented, and the merchantability has improved.

[0010]

[Table 1]

[0011]

[Comparative Example 2] Water was sprayed five times every five days from the time when the length of the summer chrysanthemum became about 30 cm. The incidence of leaf burning at the time of shipment was 70%.

[0012]

Example 2 From the time when the length of summer chrysanthemum became about 30 cm, Table 1 No. Composition 1 was diluted 1500-fold and sprayed 5 times every 5 days. The incidence of leaf scorch at the time of shipment was 2%, which prevented leaf scorch and improved commercial value.

[0013]

[Comparative Example 3] Water was sprayed every three days for two weeks after cutting and sprouts of a circular chrysanthemum. After two weeks, 90% of plants could be planted.

[0014]

Example 3 After incision of buds in a circular chrysanthemum, Table 1 No. Composition 1 was diluted 2000-fold with water and sprayed every 3 days for 2 weeks. Two weeks later, the percentage of seedlings that can be planted was 98%, and the yield of seedlings that could be planted improved.

[0015]

Comparative Example 4 Water was sprayed every three days for two weeks at the time of planting a ring chrysanthemum. The survival rate after two weeks was 92%.

[0016]

Example 4 Table 1 No. Compositions 1-4 were diluted 1500 times with water and sprayed every 3 days for 2 weeks. The survival rate after two weeks is shown in Table 2, and the survival rate was improved.

[0017]

[Table 2]

[0018]

EFFECTS OF THE INVENTION The quality of cut flowers is greatly improved by preventing leaf burning, which is a physiological injury of chrysanthemums and lilies, and by preventing cutting buds and wilting which hinders growth immediately after planting.
