Influence of post-establishment period of clonal minigarden on rooting of cuttings of eucalyptus

Abstract

The study aimed to evaluate the effect of age post-implantation of matrices ministumps in clonal minigarden on rooting of minicuttings of Eucalyptus (Eucalyptus urophylla x Eucalyptus camaldulensis). The study was conducted in an acclimatized greenhouse, designed in randomized blocks with two treatments, being two months and one year of age of ministumps in clonal minigarden, and six replications consisting, each one, by eleven cuttings. The cuttings have remained inside the greenhouse for 24 days and 6 days in full sun. The evaluations were performed every three days, from the date of the cutting until the 30th day. In this period, on each evaluation date were quantified the percentage of: modified cuttings, rooted cuttings, cuttings with roots larger than 10 cm in length. The seedlings collected from matrices with one year of establishment showed maximum rooting of 92% at 27 days, and higher than those with only 2 months of deployment with values of 41% at 24 days after the cutting. The cuttings provided with ministumps with more time of establishment and possibly greater physiological vigor showed better results in all parameters demonstrating higher rhizogenesis capacity.
