Effects of nitrogen fertilization on growth and yield of diterpene glycosides in stevia (Stevia rebaudiana Bertoni)

The effects of different nitrogen doses on dry weight yield, stevioside and rebaudioside A contents, and yields were evaluated in stevia (Stevia rebaudiana Bertoni). This study was carried out at the Instituto Federal Catarinense, Rio do Sul (SC), Brazil, under decreasing photoperiods. A randomized...

description	The effects of different nitrogen doses on dry weight yield, stevioside and rebaudioside A contents, and yields were evaluated in stevia (Stevia rebaudiana Bertoni). This study was carried out at the Instituto Federal Catarinense, Rio do Sul (SC), Brazil, under decreasing photoperiods. A randomized complete block design with four blocks and five treatments (0, 65, 135, 200 and 270 kg ha-1 N) was used. Variables related to dry weight yield (total dry weight, leaf dry weight, stem dry weight, number of secondary branches and tertiary branches, and main stem length), growth rates (total leaf area, leaf area index, specific leaf area, leaf area ratio, leaf weight ratio), and stevioside and rebaudioside A contents and yields were evaluated. The doses of nitrogen fertilization did not affect the variables related to dry weight yield, stevioside and rebaudioside A contents and yields, or rebaudioside A:stevioside ratio in stevia genotype 8 (G8), grown under decreasing photoperiods.

El efecto de diferentes tasas de nitrógeno en la producción de biomasa, el contenido y rendimiento de esteviósido y rebaudiósido A en el cultivo de estevia se evaluaron en un experimento de campo en el Instituto Federal Catarinense, Rio do Sul (SC), Brasil, en condiciones de fotoperíodo decreciente. Se utilizó un diseño de bloques completos al azar con cuatro bloques y cinco tratamientos (0, 65, 135, 200 y 270 kg ha-1 N). Se evaluaron las variables relacionadas con la producción de biomasa (DM total, tallo MS, hojas MS, número de ramas secundarias, número de ramas terciarias y longitud de rama más grande), variables relacionadas con los índices de crecimiento (AFT, IAF, AFE, RAF y RPF) y también variables relacionadas con el contenido y el rendimiento de esteviósido y rebaudiósido A. Las diferentes dosis de fertilización nitrogenada no afectaron las variables relacionadas con la acumulación de materia seca en el genotipo G8 cultivado en condiciones de fotoperíodo decreciente en las condiciones de campo. Los niveles de fertilización nitrogenada no afectaron los niveles de esteviósido y rebaudiósido A, la productividad de esteviósido y rebaudiósido A y la proporción de rebaudiósido A / esteviósido en el G8 cultivado en condiciones de fotoperíodo de disminución de campo.
