| The aim of this study was to evaluate the mini-stumps survival and the mini-cuttings production of Eucalyptus benthamii regarding to Zn and B concentrations during successive collection of shoots. Shoots were collected from mini-stumps (BP101, BP118 and BP120 clones) fertigated with nutrient solutions containing different concentrations of Zn and B (S1 – free of Zn and B, S2 – 0.5 mg L-1 Zn, S3 – 0.5 mg L-1 B, S4 – 0.5 mg L-1 Zn and B, S5 – 1.0 mg L-1 Zn and B, S6 – 2.0 mg L-1 Zn and B). Eight shoot collections of the clonal mini-garden were performed. The mini-stumps survival, mini-cuttings production, leaves number, nodes number, shoots length, internodes interval and visual appearance of mini-stumps to identify symptoms of nutritional deficiency or... |
