Physicochemical characterization of 'Pinot Noir' grapevine (Vitis vinifera L.) fruit during its growth and development under high altitude tropical conditions

Physicochemical characterization of 'Pinot Noir' grapevine (Vitis vinifera L.) fruit during its growth and development under high altitude tropical conditions

Although native of temperate climates, grapevines are grown in Colombia in the department of Boyaca, between 2,200 and 2,560 m a.s.l. Under these specific conditions, both the physicochemical behavior of the fruit and its optimum harvest time as measured in growing degree days (GDD) had remained unknown so far. On these grounds, in the municipality of Nobsa (Boyaca, Colombia), grapevines of the variety Pinot Noir were physico-chemically characterized during their growth and development. Since day 21 after anthesis (DAA) until overripening, the physicochemical characteristics of 20 berries from each of three clusters we collected every week were carefully assessed. A total of 826.2 GDD accumulated during fruit growth and development, thus completing 126 DAA. The accumulation of both fresh and dry mass followed double sigmoid curves. During early growth there was a decrease in pH, total soluble solids (TSS) and technological maturity index (TMI=TSS/TTA), coupled to an increase in total titratable acidity (TTA). After this period and until harvest, pH, TSS and TMI increased while TTA declined. Based on fresh mass, SST and TMI it was possible to set optimum harvest time at 800.6 GDD.

A pesar de ser originaria de climas templados, la uva para vino se cultiva en Colombia en el departamento de Boyacá, entre los 2.200 y 2.560 msnm, condiciones en las cuales el comportamiento fisicoquímico del fruto, así como el momento óptimo de su cosecha en función de la acumulación de grados día de crecimiento (GDC), eran hasta ahora desconocidos. Por ello, a través de la presente investigación –realizada en el municipio de Nobsa (Boyacá, Colombia)– se llevó a cabo la caracterización fisicoquímica del fruto de la variedad Pinot Noir durante su crecimiento y desarrollo. Desde el día 21 después de la antesis (DDA) hasta la sobremaduración, se recolectaron semanalmente tres racimos, de cada uno de los cuales se tomaron 20 bayas para la evaluación de sus parámetros físico-químicos. Durante el crecimiento y desarrollo del fruto se acumularon 826,2 GDC (126 DDA). Tanto la acumulación de masa seca como la de masa fresca siguieron una curva doble sigmoide. Durante el inicio del crecimiento se observó una disminución de pH, sólidos solubles totales (SST) e índice de madurez tecnológica (IMT=SST/ATT), acompañada de un aumento en la acidez total titulable (ATT). Pasado este momento, y hasta la cosecha, se observó un aumento de pH, SST e IMT, mientras que la ATT disminuyó. Con base en los registros de masa fresca, SST e IMT, fue posible establecer el punto óptimo de cosecha en 800,6 GDC.
