Abstract
Increasing production based on the use of adequate cultivars and improving growing and propagation technologies is the main trend and orientation in hazelnut culture, both worldwide and in Romania.
This was primarily due to the introduction of the intensive culture system, in which plants are trained as single trunks and where fertigation and mechanized harvesting are also applied.
The improvement of planting material aims to shorten the time of obtaining it by enhancing the propagation techniques applied in the field, in protected spaces, and in vitro.
This paper identifies and improves technological sequences through which to obtain larger quantities of high-quality planting material.
Grafting and budding are less commonly used in Romania due to the higher efficiency of hazelnut propagation through layers, as well as the special technical and environmental conditions required during and after budding or grafting.
Grafting or budding offers advantages over single-trunk training, with very few or no suckers when adequate rootstocks are used, and may also improve yield and nut quality.
When using the chip-budding method in the field, in the ecological conditions of the Vâlcea area, the success rates varied between 62 and 68%. The chip-budding of hazelnuts, carried out in the field in August, registered higher average values (64%) compared to the T-budding method (61%). At the end of the second year, the trees in the nursery have an average trunk diameter ranging from 13.2 to 13.6 mm and a height of 119-120 cm.
