In the production method of advanced seedlings, after the production of vegetative bases obtained from tissue culture in the laboratory and during the initial stages of growth in the greenhouse, transplanting is done inside the pot and inside the greenhouse, and there is no need to transfer the plant to the field. After 3 to 4 months, when the transplanted part grows and reaches a height of about 1 to 1.20 meters, the seedling is moved to the garden with its pot and no roots are separated from it. Due to the fact that in the method of producing seedlings, no roots are separated from the plant, no damage is caused to the roots, and after the seedlings are transferred to the field and planted in the ground, the plant grows quickly and reaches the same height as the plant that was produced in the traditional way. It was delivered.

Among the advantages of the seedling production method, the following can be mentioned:

• short production process; In this method, the time needed to produce seedlings is reduced to a maximum of 5 to 6 months.
• healthy and free of the produced seedlings from diseases and pests; Due to the initial production of seedlings in the greenhouse and their lack of contact with the external environment, pests and diseases, healthier seedlings will be produced.
• The possibility of building a garden in all days of the year; In this way of producing seedlings, it is not necessary to build a garden in the autumn season.
• an environmentally friendly method; Because with the production of plants in the greenhouse, less water is used for the production of seedlings.
• Shortening of the plant’s juvenile period; Since the roots are not damaged during the transfer, the period of growth is shortened.
