Abstract: This article notes the importance of stimulants and substrates in the preparation of seedlings of berry crops

entering our republic and undergoing acclimatization, some methods and their advantages. The pros and cons

of each method are described in detail. At the same time, today a number of scientific and practical works are

being carried out aimed at increasing the economic efficiency of the fruit growing industry and ensuring food

security of the population by expanding the range of fruit plants and meeting the demand for high-quality

fruits rich in vitamins. In order to ensure food security and food quality for the population of our republic and

the world community, it was emphasized that it is necessary to create existing gardens and plantations and

grow healthy, high-quality seedlings for these plantations. The rooting indicators of semi-woody cuttings of

berry fruits were analyzed in the root (control), in the working solution of Succinic (Burshtinic) acid, in the

working solution of the Radifarm stimulant, in the working solution of Giren. Belt stimulator, in working

stimulant solution

1 INTRODUCTION

Today in order to ensure food security not only in our

republic, but also on a global scale, externalization of

orchards and bleak berry fruit plantations is

considered one of the main tasks. A lot of attention is

being paid to expanding the range of berry varieties

organizing berry plantations and increasing

productivity and the quality of cultivated fruits and

berries.

In the world’s leading countries in blackberry and

raspberry cultivation specific agro technical elements

of botanical species and promising varieties,

cultivation, have been developed and scientifically

based.

On the territory of our republic, blackberry and

raspberry plantations are being established in small

areas (Alekseenko, 2005, Aleksin, 2005, Aminova,

2017). At the same time, the morph biological

characteristics of these plants and methods of

growing seedlings have not been sufficiently studied.

One of the unbent tasks of theoretical and

practical importance is to study the promising

varieties of blackberry and raspberry, which are

highly important in terms of consumption and

marketability, in the soul – climatic conditions of the

republic, and to develop methods for growing

seedlings

The aim was to determine the effect of various

stimulants on the propagation of blackberry and

raspberry seedlings from half-wood cuttings, and

experiments were conducted on varieties of

blackberry such as Natchez and Chester and raspberry

Outtim Bliss and Polka.

2 MATERIALS AND METHODS

Field and production experiment were carried out,

propagation of seedlings from semi-wooded cuttings

of blackberry and raspberry seedlings, calculation and

evaluation of standard seedling output “Seedlings and

cuttings of berry fruit plants”. General technical

“Methodology of recording and monitoring and

experiments with fruit and berry cultures”.

Cultivation of healthy blackberry seedling by

micro-cuttings method V.A.Zlenko, “Methods of

develop herd and three diseases of fruit and vegetable

culture” instruction named.

Based on the results of the research, it can be

noted that biostimuliants with different contents,

along with substrates, are of great importance in the

intensive cultivation of berry seedlings in modern

agriculture.

Berry fruit plants are mainly propagated

vegetative, working solutions of various

biostimulants that affect the rooting of cuttings of the

propagated plant were prepared and used (Aladina,

2004, Buriev et al., 2013, Buriev et al., 2012, Kefeli,

1966, Kosyakovskaya, 1989, Valieva, 2022, Valieva,

2023, Valieva, 2024). Modern new types of

biostimulants are significantly different from the

previous ones and have a positive effect on plant

development. These stimulators not only accelerate

the formation of callus in cuttings during the

cultivation of seedlings but also increase the

resistance of cuttings to stress.

3 RESULTS AND DISCUSSION

In the experiments twigs, semi –woody was cut from

2 years old branches in the cultivation of saplings of

blackberry and raspberry plants, and different

concentrations of stimulants were used to accelerate

the rooting process of the cuttings, and positive

results were achieved.

During the researches, Kornivin was selected as a

control from among the types of stimulators widely

used in the republic’s horticulture in the options

Radifarm, Yantar acid and Green Belt stimulation

were used.

With the help of these stimulants, the degree of

rooting of twigs of blackberry varieties were observed

in the rooting of twigs.

The Korniven stimulator, which was used as a

control, was analyzed in comparison with other

options.

In this table, the degree of rooting of the twigs of

the blackberry plant varieties were different under the

influence of different stimulants.

First of all, the widely used stimulant Cornevin

was used as a control in the experiment and the

indicators effect of this stimulus on the rooting of

twigs of blackberry varieties are analyzed in

comparison with other types of stimulants Natchez

species of blackberry green hall – wooden twigs in

Cornevin (control) when they were polished in 16-18

hours the rate of rooting of the cuttings were28%in

the first 10 days, and 82% of the twigs were recorded

after 30 days.

The rate of rooting twigs of this variety, when they

treated for 16-18 hours in the working solution of

Yantar acid, the rate of rooting of twigs after the first

10 days was 32% and after 30 days, it can be seen that

84% of cuttings were rooted. When the cuttings were

treated in the working solution of the Radifarm

stimulator for 16-18 hours, the rooting indicators of

the twigs were analyzed after the first 10 days, and

48% of the twigs were rooted and after 30 days, 94%

of rooting rate was found in twigs.

When the cuttings were treated in the staff

solution of Green Belt stimulator for 16-18 hours the

rooting indicators of the twigs were analyzed after the

first 10 days 44% of the twigs took root after 30 days,

93% of the twigs took root.

The experiments showed that the when the rooting

rate of green twigs of the Natchez variety was

analyzed in different stimulators, compared to the

control and other options, 12% in Radifarm

stimulator and 10% in Green Belt stimulator showed

higher rooting results.

When the twigs of the Chester variety of

Blackberry were treated for 16-18 hours in Kornevin

(control), the rooting rate of the twigs were 30% in

the first 10 days, and after 30 days, the rooting rate

was recorded in 83%of the twigs.

When the Sprigs were treated of the Radifarm

stimulator for 16-18 hours, when the indicators of

rooting in the twigs were analyzed after the first 10

days, 52%of the cuttings were rooted and after 30

days, 96% of the sprigs were rooted.

First 10 days 47% of the twigs took root and after

30 days, 95% of the sptigs were rooted.

In the experiments, when the level of rooting of

Chester variety twigs in different stimulators was

analyzed, it was observed that 13% in Radifarm

stimulator and 12% in Green Belt stimulator shoved

higher results of twigs rooting compared to the

control other options.

During the experiment the degree of rooting of

cuttings of raspberry varieties was studied. There

were certain differences between species and

varieties in rooting twigs.

The Kornevin stimulator used as a control was an

analyzed in comparison with other options.

It was observed that the degree of rooting of half-

wooden twigs of raspberry varieties was different

under the influence of different stimulators.

4 CONCLUSIONS

In the propagation of blackberry seedlings from green

twigs, in radifarm stimulator of blackberry varieties,

Natchez variety 94% Chester variety 93%, Green Belt

stimulator 96% Natchez variety, Chester variety 96%

of cuttings were rooted.

Radifarm and Green Belt boistimulants are somewhat

more effective than Kotnevin, which is currently

widely in production for rooting togs of various

plants. By using them, it was found that it is possibly

to accelerate the rooting process of cuttings of

blackberry plants and to achieve a well-developed

root system and the formation of the upper part in

seedligs.
