摘要：

Juglans regia clones were micropropagated through the establishment of in vitro shoot-tip cultures and induction of adventitious roots. Shoot proliferation of juvenile J regia material was higher than with clones established from adult trees. Genotype and juvenility of the plant material were determinant factors of the in vitro rooting ability. Rooting of adult J regia clones was improved after rejuvenation by subsequent subcultures. The sucrose concentration in the root elongation medium affected the formation of secondary roots per rooted shoot and the acclimatization of plants. Mycorrhizal inoculation of micropropagated walnut trees improved post-acclimatization growth in greenhouse conditions. Inoculation with the arbuscular mycorrhizal fungi Glomus mosseae or G intraradices significantly improved plant survival when transferred to nursery.
