Propagation of Stevia rebaudiana from stem cuttings

Propagation of Stevia rebaudiana from stem cuttings

Rooting capacity of stem cuttings of S. rebaudiana was measured monthly during an one-year period. Highest percentages of live cuttings were found between May and October while rooting occurred preferentially from May to July, when new branches were used as cuttings. During the reproductive phase of the matrix plants rooting percentage was low. IBA promoted rooting and increased root number in August and September, whereas IAA and NAA were effective only in August. These substances had no effect on the survival of cuttings. Commercially available rooting products containing auxin-like substances were inefficient in inducing roots. Analysis of total soluble sugars (stevioside here included) present in leaves of plants obtained either from germination or stem cuttings pre-treated with root promoting substances showed no significant variation in relation to the origin of plants.

A capacidade de enraizamento de estacas de Stevia rebaudiana foi avaliada mensalmente, durante um ano. Observou-se maior percentagem de sobrevivência de estacas entre maio e outubro e de enraizamento entre maio e julho, quando as plantas apresentavam ramos jovens, oriundos de brotação. Durante o período reprodutivo das plantas matrizes, a percentagem de enraizamento foi baixa. Aplicação de AIB promoveu enraizamento em agosto e setembro e formação de maior número de raízes, enquanto AIA e ANA foram eficazes apenas em agosto. Estas substâncias não alteraram a sobrevivência das estacas. Produtos comerciais utilizados como enraizadores, apesar de conterem substâncias auxínicas, foram ineficientes na indução do enraizamento. A análise de açucares solúveis totais (entre os quais encontra-se o esteviosídeo), em folhas de plantas obtidas por germinação ou por estacas tratadas ou não com substâncias promotoras de enraizamento, revelou que não houve variações significativas relacionadas à origem das plantas.
