JPH02255604A - Rooting accelerator composition - Google Patents

Abstract

PURPOSE:To obtain a rooting accelerator composition capable of exhibiting rooting accelerating effects by using amino acids, such as glycine, alanine, glutamic acid or aspartic acid, with a choline salt in combination. CONSTITUTION:A rooting accelerator composition containing one or two or more compounds of choline salts (especially preferably hydrochloride, phosphate or nitrate) and one or two or more of amino acids, such as glycine, alanine, glutamic acid and aspartic acid. Alanine and aspartic acid and especially preferred as the amino acids. The mixing weight ratio of the choline salts to the amino acids is preferably within the range of 1:(0.1-10).

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a novel plant rooting promoter composition.

More specifically, the present invention relates to a rooting promoter composition containing one or more choline salts and one or more amino acids glycine, alanine, glutamic acid, and aspartic acid.

[Prior Art] It has been known that rooting can be promoted by immersing sweet potato seedlings in a choline solution. It is also known that treating rice seeds with choline salts has the effect of promoting rooting and growth. “Patent Publication 1986
2-2123044 However, its rooting promoting effect cannot be said to be sufficient.

[Means for Solving the Problems] Under such circumstances, the present inventor has conducted intensive research to solve the above problems, and has found that a composition containing a specific amino acid in combination with choline salt has excellent rooting promotion. The present invention was completed after discovering that the present invention is effective.

In other words, by using one or more choline salts in combination with one or more amino acids glycine, alanine, glutamic acid, and aspartic acid, remarkable rooting that is not seen when each is used alone can be achieved. They discovered that it has a promoting effect and completed the present invention.

In the present invention, choline salts include inorganic salts such as hydrochloride, phosphate, polyphosphate, sulfur salt, nitrate, silicate, carbonate, acetate, citrate, lactate, L( +)
This refers to organic acid salts such as tartaric acid salts, and hydrochlorides, phosphates, and nitrates are preferred.

The amino acids include glycine, alanine, glutamic acid, and aspartic acid, with alanine and aspartic acid being particularly preferred.

These amino acids hardly exhibit a rooting promoting effect when used alone, but they exhibit a rooting promoting effect when used in combination with choline salt. Furthermore, amino acids such as ornithine, valine isoleucine, leucine, titrulline, and arginine do not exhibit rooting promoting effects even when used in combination with choline salts.

The mixing ratio of choline salt and sugar is 1:0.02 to 50 by weight.
and 1:O, 1-10 is particularly preferred.

When the blending ratio is outside the range of 1:0.02 to 50, favorable effects cannot be obtained.

Further, the composition of the present invention may have a choline salt concentration of 1 to 5, for example.
A solution is prepared so that the concentration is 0% by weight, and when used, the solution is diluted so that the concentration of choline salt is usually 10 to 1,500 ppm, and then applied to the seeds, roots, stems, and leaves of plants. The fertilizer can also be used in combination with fungicides, insecticides, herbicides, and plant growth regulators.

[Effects of the Invention] The rooting promoter composition of the present invention exhibits an excellent rooting promoting effect when applied to seeds, roots, and foliage of plants.

[Example] The present invention will be explained below with reference to Examples.

Example: Spread Toyo 3 paper (No. 9) on a petri dish with a diameter of 9 cm.
6 d of a mixed solution of choline chloride, choline phosphate, and amino acids was poured into the flask, and 7 paddy rice (variety: Akiharu) seeds and 5 Jaena seeds were placed on the bed. After that, indoors (night 16℃, daytime 2
6° C.), and root length was measured 7 days after application.

Table 1 shows the results of a combination test of choline chloride and amino acids, and Table 2 shows the results of a combination test of choline phosphate and amino acids.

The captain indicated the ratio with the untreated area set as 100.
