し、このような知見に基いて本発明をするに到った。Means for Solving the Problems The present inventor has found that, like the flower bud formation promoter of the present invention, an aqueous solution of high-purity proline at a specific concentration is useful as a quality improving agent for fruit and fruit of fruit trees or fruit vegetables. It was discovered through an application test to Japanese pear "Kosui" and based on this finding, a patent application was separately filed for "the quality improving agent for fruits and grains" (Japanese Patent Application No. 2001-23).
5266). In this application test, the present inventor has also found that the above-mentioned proline aqueous solution has a flower bud formation promoting action, and has arrived at the present invention based on such findings.

It has a remarkable effect on strawberry).

を意味する。The proline to be used in the present invention is L-form (L-Pro) because of its compatibility with plants.
The purity is 50% or more, preferably 70% or more,
More preferably, it has a high purity of 90% or more. The reason for such high purity is to avoid the damage caused by impurities such as salt damage and to make proline effective.
The purity of proline referred to in the present invention is the proportion of proline in the solid content in the aqueous solution of proline which is the flower bud formation promoter of the present invention, and% in the present specification is% by weight.

からである。The high-purity proline is preferably in the form of an aqueous solution, and is applied to the target plant in this form, with a concentration of 15 to 1,500 ppm, preferably 20 to 1,000 ppm, more preferably Is 40-50
It is set to 0 ppm. This is because if the concentration is lower than this, the effect of applying proline is not exerted, while if it is higher than this, growth inhibition occurs.

の散布（狭義）のみならず、適宜、葉以外の果実・子実
を含む地上部位への散布をも含む（広義）。The application method is preferably foliar application (spraying of an aqueous solution) from the reason of preventing the decomposition of proline by soil microorganisms. The leaf surface may be either the front surface or the back surface of the leaf, but the back surface is more preferred. It is considered to be better for absorption of proline. The term "foliar application" as used herein includes not only literal application to the leaf surface (narrow sense), but also appropriate application to the above-ground parts including fruits and fruits other than leaves (broad sense).

滴り落ちる程度とすることもできる。The application amount of the flower bud formation promoter is, in short, the amount at which the flower bud formation is promoted as compared with the case where it is not applied. This amount is found, for example, in the test examples shown below. Similarly, the aqueous solution of the flower bud-promoting agent may drip from the leaf surface.

Proline) is sprinkled on the leaves of Japanese pear "Kosui".
The effects on fruit maturity and quality were examined. In other words, using "Kosui" from a cultivated garden of an advanced farmer with advanced cultivation technology, physiological studies such as the mechanism and dynamics of proline application were not carried out, and the amino acids applied exogenously were only Japanese pear. This study focused on how it is related to fruit quality improvement and maturation progress, and flower bud differentiation related to the results of the next year.

いては両区に差異は認められなかった（下記第２表）。(2) Results and Discussion: Looking at the number of fruits by harvest date, fruit maturation showed a slightly faster tendency in the proline-treated area. From the distribution of fruit classes on each harvest day, it was confirmed that the fruits in the proline-treated plot were large on any harvest day (Figs. 1 (a) to 1 (c)). Although there were no major differences in the traits of the harvested fruits, the fruits in the proline-treated group had a higher sugar content in the fruits harvested on August 24 and had a slightly reddish skin color, which was consistent with the earlier ripening tendency. No difference was observed in the trait changes after harvesting between the two plots (Table 2 below).

味深い。The fact that the sugar content was higher than that of the fruit could be inferred from the fact that the Sorbitol content was obviously high in the treated group when the content of sugars in the fruit was examined (Table 3 below). Sorbitol is known to be the transmigrant sugar of the rose family plants such as Japanese pear, but it is interesting that there is a difference in this sugar.

驚くべきことである。Regarding the flower bud differentiation rate, it was confirmed that the flower bud differentiation on the long fruit branches was clearly promoted in the proline-treated group (Table 4 below). This is a surprising thing that could never have been expected.

As a countermeasure, it is recommended that balanced fertilization management should be carried out by avoiding a temporary large input of nitrogen fertilizer in view of the nutrient absorption mode of "Kosui" trees. But,
It is difficult to control the nutrients of fruit trees, which are perennial crops, and if the nutrients can be regulated by foliar spraying like this time, it can be an extremely advanced cultivation technique.

結果である。Table 5 below shows the results of the taste sensory test of the sprayed product (product of the present invention) and the non-scattered product (control product) by a panel of 40 people. The rating of the sprayed products shown in the table was obtained as follows. That is, with "non-scattered product" as 0 point (control), +3, +2, +1, 0,-
A score of "scatter" is given in a 7-point scale of 1, -2 and -3 using a multiple comparison panel, and the average of the scores given to "scatter" by multiple panels The value was calculated and used as the rating for "scattered product" in the table. Therefore, the numerical values in Table 5 are the results showing the rating of "scattered product" as the distance from "non-scattered product".

る。EFFECTS OF THE INVENTION By promoting flower bud formation according to the present invention, for example, fruit trees and vegetables can produce large-sized large fruits as compared with the case where they are not, and, for example, cherry trees use helicopters and the like. Then, when a high-purity proline aqueous solution is sprayed on the trees, these trees have many flower buds and the entire surface is covered with flowers.
