Growth tissue from buds of approved plus trees.
From mid-December to February, the winter cuttings are pruned to be stored temporarily and then processed further.
Shoot pieces with terminal and lateral buds are sterilized; afterward, the bud scales are removed, and the growth tissue is carefully prepared.
The explants are placed on a nutrient medium and further cultured.
After the shoots have sprouted, they are divided and placed back onto the nutrient medium.
After root formation, the seedlings are transferred from the controlled environment to soil, acclimatized, and then moved to the open field for further cultivation until they reach a suitable planting size.
