dc.descriptionThe low percentage of seed germination and adventitious root induction in cuttings of Piptocarpha angustifolia has limited its silvicultural use. Thus, we studied the effect of tissue maturation on successive collections of mini-cuttings grown in a semi-hydroponic system. Likewise, we evaluated potential multiplication via the mini-cutting technique by assessing the survival and productivity of mini- stumps as well as the formation of adventitious roots and the root vigor. We ma de 32 sprout collections during two years in a clonal mini-garden. From these collections, mini-cutting experiments were installed throughout several season s. Mini-cuttings of 8 ± 1 cm long were prepared, planted in boxes with vermiculite and carbonized rice husk (1:1 v/v) and placed in a greenhouse. After 70 days, we evaluated the adventitious rooting percentage as well as the adventitious root an d aerial vigor of the mini-cuttings. The appropriate survival of mini-stumps (68%) an d the annual produc tion of mini-cuttings per square meter (2,227) reflected the efficiency of the semi-hydroponic sy stem for this species. The increasing rooting, multiplication rate and root vigor indicate no maturity in the course of the collection of mini-cuttings in P. angustifolia mini-stumps .
