Initial development and yield in sugarcane from different propagules

Abstract

The use of small sections of sugarcane propagules for planting brings new challenges, due to the use of different parts of the stem, since each one contains different concentrations of reserves and hormonal balances. This study aimed to assess the influence of types of propagules used for planting sugarcane. A field experiment was carried out using a randomized block design, with three replications, in a 3 x 3 factorial arrangement (propagules with 2, 3 and 4 buds from the apex, middle and base of the stems). The original position (apical and central) and the number of buds of the propagules (2 and 3 buds) influenced the initial development of the plants and, consequently, their yield. The interaction between these two factors showed that, as the number of buds of the propagules decreases, their position plays an important role in budding. Thus, when smaller propagules are used for the establishment of sugarcane, the original position of the bud in the propagule should be considered.
