Application Of Plant Growth Regulator In Grapes

- Jan 10, 2018 -

1.Expanding fruit, improving quality, increasing production

Gibberellin  The growth hormone in granulocytes was increased with gibberellin, Prompted cells elongated, enlargement, and transfer the organic nutrients to the fruit grain of transportation and accumulation, a rapid increase pulp cell inclusions, which increased fruit grain of 1 or 2 times, which obviously improves the commodity value. Gibberellin alone though an increase fruit grain of role, but also make stem brittle easy to fall, the side effects of grain in use can be added BA (6 - card purines), streptomycin, to prevent the concrete with method owing to the different varieties and using method need to be decided upon by experiment. It is necessary to cooperate with good agricultural techniques to obtain the ideal effect when the fruit granule is increased with gibberellin.

It is necessary to cooperate with good agricultural techniques to obtain the ideal effect when the fruit granule is increased with gibberellin.


Triacontanol    Xinjiang agricultural eight division 152 farms use 0.5mg/L 30 alkanol plus 150g of potassium dihydrogen potassium, spraying grape with 613kg per mu yield, increasing by 101%.


 Daminozide    15 to 30d before harvest, spraying with 1000mg/L~2000mg/L leaves can increase the hardness of fruit.If the fruit is soaked with 1000mg/L~ 2000mg/L, it can prolong the storage period.


Wenduo rich(The main ingredient: gibberellin +BA)  The size of the green beans of the seedless white chicken is about 30~ 50mg, and the dot is applied to the base 2cm of the ear, and the puffed fruit can increase the yield by about 30%.


Mepiquat chloride   It can increase the absorption of calcium ions, prevent the Browning of the fruit, reduce the core, reduce, increase the pulp quantity, and improve the fruit quality.


Cytokinin + gibberellin   The fruit panicles of the giant peaks are 10d, 20d, and the heads of the fruit are sprayed with the mixture of cytokine and gibberellin, which can be the same size as a nuclear fruit, and the fruit can increase to 50%.


 CCC   In grape flowering or young fruit enlargement period mu, with 500 ~ 800 mg/L liquid spraying, can promote the formation and differentiation of flower buds, improve fruit-set rate, adding sugar and vitamin c content, fruit large, neat, mature early, 3 ~ 4 d, increase production, improve quality.


Abscisic acid (ABA)    When the fruit starts to mature, it can be sprayed with 100~200mg/L of abscisic acid, which can promote the coloring and maturation of red honey, pioneer and red variety of the chuanchuan, and also enhance the sweetness of the fruit.


KT-30    There is a nuclear variety: 10~15d with 20mg/kg of pyromyloxacin leaching for 5~10 seconds, can promote cell division, prevent falling fruit, and can effectively promote the growth of grape fruit. Seedless variety: it can be mixed with gibberellin, which is 15mg/kgKT-30 and 100mg/kg gibberellin. It can promote cell division, prevent falling fruit, and can effectively promote the growth of grapes. It should be noted that the concentration of KT-30 should not exceed 20mg/kg, and the fruit time should not be too early, otherwise it is easy to form the phenomenon of size and size.


Note: KT-30 should be used with the match. After placing 1d, the effect will decrease significantly.The effect of KT-30 on the growth of fruit is obvious. There is a certain practical value, which can be used as the fruit development promoter, which can achieve best results only if the tree is strong and abundant. The application concentration and period are suitable for a certain range, preferably with low concentration and late period. It must be even and considerate in leaching, smearing and spraying, otherwise it is easy to produce deformed fruit and reduce the value of goods. In the promotion of fruit enlargement, the enlargement rate should be about 20%, and combine with the appropriate fruit.



2. Early maturity

Ethephon  As the fruit ripening agent, is the commonly used early coloring, when used for concentration and time vary with varieties, generally applied in berries mature beginning period of 100 ~ 500 mg/L, color varieties in 5% ~ 15% fruit coloring, mature ahead of 5 ~ 12 d. The experiment showed that, when the fruit began to mature, the fruit panicle was dipped in 250~300mg/L of ethylene, and it was able to mature early 6~ 8d. But the use of the ethylenel to produce an ionosphere between the resulting granules and the fruit stalks. Therefore, we should master the concentration, stage spraying, installment, and installment sales, in case of loss. The optimum concentration of different grape varieties is different, and the optimum concentration and method is determined by experiment.


Gibberellin  With the low concentration of gibberellin maceration, the ripening stage of grape berry can be significantly advanced, and the economic benefit of the treatment of panicle can be greatly improved by the treatment of the panicle.


3. Delay mature

ATOA2- tetrazazole and thioacetic acid)   At the beginning of the young fruit, the fruit can be carefully sprayed with 10~100mg/L in the stage of maturity. The mature and delayed cultivation of grapes can be delayed to prolong the supply of grapes.Concentration high-delay mature effect more apparent, but must pay attention to the grape leaf drug sensitive, generally above 200 mg/L can form the adr, must pay attention to when using do not put the liquid onto the blades.



4. Fruit denuclearization

Gibberellin   Using the method of impregnation of the large plastic cup one by one, the concentration of rose dew was treated with the concentration of rose dew at 100mg/L, and the dosage of each ear was about 0.5ml.The treatment of the ear growth was about 1.5ml per ear.Before the flower, use the artificial panicle impregnation method. After the flower, use a manual sprayer to apply the shower spray to the panicle.It should be chosen to avoid a period of above 30 degrees before sunset on a sunny day, or after 3 PM, before sunset.The relative humidity is around 80% and can maintain 2d. Dry weather, easy to cause drug damage, bad weather treatment.This weather should be avoided in field operation.If the downpour can no longer be treated after handling 8h, the large amount of rain will be washed out again.In turpan region of xinjiang, the two or three branches of the seedless white grape are very serious, with the use of gibberellin, the yield of fresh grapes is 74%, and the raisins can increase by 50.3%.There are many seeds in the rose dew grape, and after using gibberellin, gibberellin makes the growth rate of grape pollen and embryo sac not consistent, thus forming seedless fruit.


According to the experiment, with the rose grape of gibberellin, the seedless rate can be about 95%.Using gibberellin is suitable for the seedless white and rose grape varieties, normally with gibberellic acid 100 mg/l liquid coated about 14 d before immersion in inflorescence, shake them a little for the fully by medicine, lose pollen germinating capacity, but easy to make fruit grain of smaller.Therefore, about 9d after the flowering period, 100mg/l leaching of gibberellin was used.In a large area of grapes, the flower can be used to start with about 12d of gibberellin and about 100~ 200mg/L, which can be sprayed in the inflorescence, and can not be sprayed on the leaves.Note that gibberellin to underwriting fruit only adapt to the part of the grape varieties, giant peak grapes cannot have this effect, it will form a small fruit, shawl, affect the edible value, so the other grapes can adapt to the need to be based on the experiment;Gibberellin on other European seedless varieties and seed abortive easily and grain varieties, there are also improve seedless fruit grain of effect, but the concentration of gibberellin low (< 20 mg/L), promote the growth of new slightly instead urged fruit grain fall off, especially coated spraying can cause production.


2,4-D    Using 10mg/L solution to spray the flowers, the ovary can not be fertilized and the seedless fruit can be expanded to increase the yield of grapes.


Gibberellin+Agricultural streptomycin  The giant peak inflorescence was 100mg/L with gibberellin + Agricultural streptomycin 400mg/L treatment the non-nucleation rate is 95 %, and it can promote early maturity and improve the content of soluble solids.Although the non-nucleation rate of the black orin variety can reach 98%, the fruit granule increases and the ear weight is obviously low, so it is not used.


4-Chlorophenoxyacetic acidPCPA  5 d before sheng flower, PCPA 15 mg/L and gibberellin 20 mg/L mixture processing grape, after sheng spent 10 d treated with ga3 15 mg/L and can induce the formation of seedless grapes, seedless rate can reach 100%, seedless fruit average grain weight 6.97 ~ 9.08 g, fruit grain loss rate is only 8.7%, still can make ripening by 10 ~ 15 d.


Gibberellin+4-Chlorophenoxyacetic acid   Induced huge peak fruit grain of denuclearization, alone with ga3 or chlorobenzene itch acetic acid treatment effect is not ideal, seedless rate reach more than 90%, and the adr is serious, and with ga3 10 ~ 15 mg/L liquid add fluid of chlorobenzene itch acetate 15 mg/L, 5 d dipping flower version before flowering, seedless rate can be as high as 97.1% ~ 97.1%, the adr, the stability of fruit, fruit pulp well developed.After 10~ 14d, it was treated with gibberellin 25mg/L solution for 1 time. The fruit granule increased significantly, and the maturity stage was 10~15d in advance, and the economic benefits were obvious.


Precautions: use strictly in accordance with the prescribed concentration, otherwise the drug will be susceptible to drug damage.When dispensing with a small amount of hot water to dissolve the powder in sufficient quantities, the agent can not be used in combination with alkaline fertilizers and pesticides.


Gibberellin+ antibiotic   The peak grape flowering period was 200mg/L kanamycin +200mg/L streptomycin + (50 ~150 mg/L) mg/L gibberellin, with a non-nuclear rate of 100%, and the second and third general use of fruit granulator.
