Phenotypic performance of four stevia genotypes in the Alto Vale do Itajaí region, Brazil
An evaluation of four stevia genotypes for biomass yield, stevioside and rebaudioside A content and yield under decreasing photoperiod conditions was carried out in the Alto Vale do Itajaí region, located in the State of Santa Catarina (SC), Brazil. This field experiment was conducted at Site São Mi...

| description | An evaluation of four stevia genotypes for biomass yield, stevioside and rebaudioside A content and yield under decreasing photoperiod conditions was carried out in the Alto Vale do Itajaí region, located in the State of Santa Catarina (SC), Brazil. This field experiment was conducted at Site São Miguel, a farm located in the city of Lontras (SC), Brazil, under conditions of decreasing photoperiods, with a variation of 13.72 h of light at experiment implantation to 12.57 h of light at the end of the evaluations. The treatments consisted of four genotypes (G4, G8, G9 and G12) provided by EMBRAPA-CENARGEN. A randomized complete block design with four treatments (stevia genotypes) and four replications was used. Each plot consisted of 21 plants, and the floor area had five plants. G12 had the highest leaf dry weight (LDW), total leaf area, leaf area index, leaf area ratio and specific leaf area of all the genotypes. G4 and G12 were equal for LDW and were higher than the other genotypes, with yields of 755.6 and 836.4 kg ha-1, respectively. The stevioside content was highest in G12 (200.07 mg g-1). G8 and G9 were similar for rebaudioside A content (64.77 and 49.05 mg g-1, respectively). The rebaudioside A: stevioside ratio was highest in G8 (0.44 g g-1). No genotype had a rebaudioside A: stevioside ratio suitable for industry requirements. |

Bertoni Esteviósido Rebaudiósido Edulcorantes An evaluation of four stevia genotypes for biomass yield, stevioside and rebaudioside A content and yield under decreasing photoperiod conditions was carried out in the Alto Vale do Itajaí region, located in the State of Santa Catarina (SC), Brazil.

La evaluación de cuatro genotipos de estevia para la producción de biomasa, el contenido y rendimiento de esteviósido y rebaudiósido A, se llevó a cabo en la región de Alto Vale do Itajaí, estado de Santa Catarina, en condiciones de disminución de fotoperíodo. El experimento se realizó en el campo de la Granja São Miguel, Lontras, SC (Brasil), bajo condiciones de disminución del fotoperíodo, con una variación de 13.72 h de luz, en el momento de la implantación del experimento, a 12.57 h de luz al final de las evaluaciones. Los tratamientos fueron cuatro genotipos (G4, G8, G9 y G12), procedentes de EMBRAPA-CENARGEN. Se utilizó un diseño de bloques completos al azar con cuatro tratamientos (genotipos de estevia) y cuatro repeticiones. Cada parcela constaba de 21 plantas y el área del piso por cinco plantas. G12 tuvo el mayor peso seco de la hoja (PSH), área foliar total, índice de área foliar, relación de área foliar y área foliar específica de todos los genotipos. G4 y G12 presentaron similitud en PSH, siendo superiores a los demás, con producción de 755,6 y 836,4 kg ha-1, respectivamente. El contenido de esteviósido fue mayor en G12 (200.07 mg g-1). G8 y G9 fueron iguales para el contenido de rebaudiósido A, presentando 64,77 y 49,05 mg g-1, respectivamente. La relación rebaudiósido A: esteviósido fue mayor en el genotipo G8 (0,44 g g-1). Ningún genotipo evaluado bajo las condiciones productivas del Alto Vale do Itajaí presentó la relación rebaudiósido A: esteviósido apropiada requerido para la industria.
