USING DIFFERENT TYPES OF CUTTINGS AND SUBSTRATES. Rev. Fac. Nac. Agron. Medellín [online]. 2008, vol.61, n.1, pp.4347-4357. ISSN 0304-2847.

In order to contribute to the knowledge of the asexual propagation of cape gooseberry, this study was established with the aim to evaluate the use of cuttings from different plant parts: first third (apical shoot part), medium and basal third of the productive shoot; leaf solely and leaf with axillary bud. The characteristics of rooting were identified (length, fresh and dry weight of roots), and some changes of cutting's magnitude (fresh weight of the cutting, length of the axillary sprout) during the vegetative growth cycle. The cuttings ( 16 cm long, 2 nodes, with a pair of leaves in the superior node) were established in different substrates: sand; soil:rice husks (1:1 v/v) and sand:soil:rice husks (1:1:1 v/v) and were held under conditions of high relative humidity (90%) and an average temperature of 24°C. The results showed statistical differences between types of cutting; being the apical third of the shoot, which obtained longest root length, highest root dry and fresh matter and percentage of rooting. Regarding substrates best conditions for rooting of cuttings were obtained in sand, where seedlings had the highest percentage of rooting, however significant differences only were found with root length and axillary sprouts.
