Description

Description: TECHNICAL FIELD The present invention relates to a method for increasing the yield of cucumber fruits of the same sex line.

Conventional technology The foliage of female strain and hermaphroditic strain, cucumber, was removed from 0.019 to 0.057.
It is known that the number of female flowers in the female strain increases compared to the control group by the treatment with abscisic acid at a concentration of 5 to 8 times, but the number of flowers of the same male and female strain is similar to that in the control group. ing. [Plant and Self Physiology
(Plant and Cell Physiology) 15 , 635-642 (1974)].

Female and male and female strain cucumber foliage of 0.038 to 3.8 mM
It is known that daily treatment with a concentration of abscisic acid for 21 to 25 days promotes the development of female flowers of female strains, but it is inversely inhibited in hermaphroditic strains [Id.
18 , 261-269 (1977)]. It is known that when the stems and leaves of the female strain cucumber are treated with aminoethoxyvinylglycine, female flowers are changed to male flowers, or amphoteric flowers, or female inflorescences are changed to female flower complex nodes or female flower and male flower complex nodes.

nd Cell Physiology), 20 (8), 1547-1555 (1979)].

When the stem and leaves of the female strain cucumber are treated with silver nitrate, the female flowers become male flowers or amphoteric flowers, and in some cases the female node is a female compound node, a male-female compound node, a male-amphoteric flower compound node or a female flower and amphoteric flower. It is known to change into compound nodes of flowers. (Plant and Cell Fyzology (Pla

].

Ethylene (2-chloroethanephosphonic acid), which is an ethylene generator, is known as a drug exhibiting a remarkable female flower inducing effect. When 0.692 to 1.384 mM solution of esrel is applied to main-branch / side-branch fruit-bearing type foliage (2nd to 4th leaf stage), the number of female flowers on the main branch is remarkably increased and the yield from the main branch is increased. The yield of side branches decreases due to a decrease in the number of side branches occurring as the number of female flowers on the main branches and the number of harvested fruits increase. Therefore, the total yield is the same as or less than the control. In addition, more than half of the total yield of the main branch / side branch varieties depends on the side branch, so a decrease in the yield from the side branch directly leads to a decrease in the total yield. Furthermore, the effect of ethrel varies depending on the type and variety of crops, and the appropriate range of treatment concentration varies depending on temperature, and there are problems such as shortening of fruit (new edition horticultural use of plant regulators, Nobutaka Takahashi et al. , Seibundo Shinkosha, published in 1980).

Problems to be Solved by the Invention None of the conventional methods has been successful in increasing the yield of cucumber fruits of the same sex line. There is a constant demand for the development of an excellent agent for increasing the yield of cucumber of the same-sex line.

Means for Solving the Problems According to the method of the present invention, the stems and leaves of the hermaphroditic strain cucumber are treated with an ethylene biosynthesis inhibitor, an ethylene action inhibitor or abscisic acid at a concentration of 0.001 to 0.015 mM,
Alternatively, the stems and leaves are treated with the enrene generator at the time of the second to fourth true leaves of the cucumber of the same strain of male and female, and then the stem is treated with an ethylene biosynthesis inhibitor, an ethylene action inhibitor or abscisic acid during the 1st to 5th days. By treating the acid, the yield of the cucumber can be increased.

Any treatment method may be used as long as the entire surface of the foliage is uniformly wet.

The number of treatments is usually 1 to 2 times for each treatment period.

Examples and reference examples for preparation of preparations are shown below.

Example 1. In a polypropylene cultivation pot with a diameter of 13 cm containing gravel,
Cucumber seeds (variety: Tokiwa Mating Arctic No. 2) were sown and grown in a hydroponic facility in which a balanced culture solution was circulated. Cultivation tank (length, 3150 mm, width, 1050 mm, height 85 mm) 1
There were 8 plants with 2 rows planted per tsubo. Germination in hydroponics,
Raising seedlings, planting, attracting, pruning, plucking and controlling pests were in accordance with the conventional law. The hydroponic facility used is Kyowa-style hydroponic hyponica [agriculture and horticulture, separate volume hydroponic cultivation of vegetables, pages 40-45, issued November 15, 1973].

The liquid temperature of the hydroponic liquid was 28 ± 2 ° C. from seeding to planting, and the salt concentration (EC) of the balanced culture liquid was 1.5 to 2.0 mmho. After planting, the liquid temperature should be 20 ± 2 ℃ and the EC should be 2.2-2.6.
kept at m mho. The pH of the hydroponic solution is 5.
It was kept at 5 ± 9.

When the third true leaf of the cucumber was developed to about half, the chemical treatment was carried out by spraying the chemical liquid having the predetermined concentration shown in Table 1 until the chemical liquid dripped over the whole foliage.

The drug was treated once.

After the chemical treatment, the side branches of the first to third sections of the main branch originally had a small amount of harvested fruits, and thus were removed in a timely manner. In addition, the 18th or more section of the main branch was corened. In other words, it was decided to stop Section 17 of the main branch. Furthermore,
The side branches of the main branch 4th to 17th sections were used as the side branch first section stop, and the side branch second section and above were removed.

The female flower, the male flower and the fruit generated during the test period were continuously harvested each day. The fruit was harvested when the fruit length reached about 18 cm (weight was about 60 g). Cultivation was stopped when the occurrence of female flowers decreased and the vigor decreased. The harvest period of fruits varies depending on the season, but is about 1.
5 months. The test is 10 plots in 1 ward, and the result is the
Shown in the table.

As is clear from Table 1, by using abscisic acid, an ethylene biosynthesis inhibitor and an ethylene action inhibitor as a cucumber foliage treatment agent, the yield of cucumber fruits can be increased.

In addition, the defective rate of the harvested cucumber (curved fruit, narrowed fruit,
Deformation fruit rate with no commercial value such as swelling fruits and constricted fruits)
Comparing the control section and the chemical treatment section, 1 to 15 in the previous section
%, There is some variation in the type and concentration of the drug, but 3 in the rear ward
It was ~ 14%, and no difference was observed between the two plots.

Example 2 The results of Table 2 were obtained in the same manner as in Example 1 except that the chemical treatment was performed as follows.

Regarding the pharmacological treatment, when the third true leaf of the cucumber developed to about 1/3, 0.75 mM ethrel solution was sprinkled over the entire foliage (pretreatment). Three days after the treatment of ethrel (at the time when the third true leaf was almost completely developed), various chemical solutions having the predetermined concentrations shown in Table 2 were sprinkled on the entire foliage (post-treatment).

As is clear from Table 2, by using the pretreatment of esrel and the post-treatment of the drug in combination, the cucumber fruit can be produced not only in the control but also in the treatment of the drug alone used in the post-treatment. The sales have increased significantly.
