Abstract

RODRIGUES, Paulo Hercílio Viegas; BORDIGNON, Stevan Ricardo  and  AMBROSANO, Glaucia Maria Bovi. Horticultural performance of in vitro propagated plants of Sacha inchi. Cienc. Rural [online]. 2014, vol.44, n.6, pp.1050-1053. ISSN 1678-4596.  https://doi.org/10.1590/S0103-84782014000600016.

The aim of this study was to evaluate, in the field, the horticultural characteristics of Sacha inchi (Plukenetia volubilis L.) in vitro plants considering time of flowering and harvesting, the productivity, as well as their morphological characteristics: color and shape of leaves, stems and fruits. The plantlets, originated from the apex of in vitro plants, were propagated in culture medium with MS salts and vitamins, add 30g L-1 sucrose and 1.0mg L-1 BAP for six weeks. Were selected at random, four plants propagated in vitro, four plants by seminal and twenty-two plants, also by composing the border, totaling thirty plants. Analyses were completed weekly until fourteen months after planting, which occurred before the first pruning. The results indicate the non-occurrence of genetic variability in vitro grown plants, as well as early in the production and increased productivity as compared with the conventional material obtained via seminal.

Keywords : omega 3; Plukenetia volubilis; Euphorbiaceae; Somaclonal variation.
