comparing water deficit and saline stress between 1103p and 101-14mgt rootstocks, grafted with cabernet sauvignon |
| description |
In arid regions under irrigation, vineyards often face water deficit and salinity. As these stressors often occur simultaneously, it is difficult to assess their individual relative severity. The aim of this work was to independently study the physiological responses of grapevine to salinity and water deficit, in order to understand and compare their effects. A pot trial was designed, grafting Cabernet Sauvignon onto 1103P and 101-14 Mgt. Three treatments were evaluated: saline irrigation (Salino; 80 mM ClNa and field capacity), water stress (EH; 0,4 faction of soil transpirable water and 2 mM NaCl) and a control (T; without any stress factors, field capacity and 2mM NaCl). After 54 days, Salino showed smaller effect on leaf area (AF) and shoot length than EH. AF diminished 53% for Salino, while for EH, AF was reduced in a 78% with respect to T. Shoot length diminished 68% for Salino and 83% for EH. Total biomass did not show any difference between both stresses, falling 52% for both situations. However, regarding the biomass partitioning, Salino had higher canopy dry weight while EH showed higher root dry weight. Midday leaf water potential was -1,3 MPa for Salino and EH and -0,9 MPa for T. Although stomatal conductance was similarly reduced for both stress treatments (-41% compared to T), with no differences between rootstocks; an interaction was found between the type of stress and rootstock for net photosynthesis. Finally, 1103P showed a higher Na+ exclusion power than 101-14Mgt (accumulating 21% less Na+ in the plant). Even though the behavior of the Cabernet sauvignon scion was similar for both rootstocks, the higher exclusion that 1103P showed may indicate possible better performances upon salinity. |

En zonas áridas bajo riego, los viñedos enfrentan condiciones de déficit hídrico y salinidad. Como frecuentemente estos factores de estrés ocurren simultáneamente, es difícil evaluar la gravedad relativa de cada uno de ellos. Elobjetivo del trabajo fue comparar en forma independiente las respuestas fisiológicas y vegetativas al estrés hídrico y salino de dos portainjertos de vid injertados con Cabernet Sauvignon. Se realizó un experimento en macetas con vides injertadas con Cabernet Sauvignon sobre 1103P y 101-14Mgt. Se aplicaron tres tratamientos: estrés salino (Salino), estrés hídrico (EH) y testigo sin estrés (T). El Ψ foliar a mediodía fue -1,3 MPa en Salino y EH, y -0,9 MPa en T. Luego de 54 días, Salino afectó menos el área foliar (AF) y la longitud de brotes (LB) que EH. El AF disminuyó 53% en Salino, mientras que en EH se redujo 78% respecto de T. La LB disminuyó 68% en Salino y 83% en EH. La biomasa total no presentó diferencias entre los dos tipos de estrés, disminuyendo ambos un 52% respecto de T, pero la partición de asimilados a los distintos órganos fue distinta. Salino acumuló más biomasa en parte aérea y EH en raíz. Aunque la conductancia estomática se redujo de manera similar en ambos tratamientos de estrés (-41% respecto del T) se encontró una interacción entre tipo de estrés y portainjerto para la fotosíntesis neta. Las plantas injertadas sobre 1103P acumularon un 21% menos de Na+ que las injertadas sobre 101-14Mgt. A pesar que el comportamiento de las plantas Cabernet Sauvignon injertadas fue similar para ambos portainjertos, la mayor exclusión de 1103P lo hace más propicio ante situaciones de salinidad.
