Seasonal fluctuations inVitis viniferaroot respiration in the field

Summary• We studied the seasonal fluctuation of soil respiration (R S ), and its rootdependent (R R ) and basal (R B ) components, in a Vitis vinifera (Chardonnay) vineyard.• The R S components were estimated through independent field methods (y-intercept and trenching) and modeled on the basis of a Q 10 response to soil temperature, and fine and coarse root respiration coefficients. The effect of assimilate availability on R R was assessed through a trunk girdling treatment.• The apparent Q 10 for R R was twice that of R B (3.5 vs 1.6) and increased linearly with increasing vine root biomass. The fastest R R of fine roots was during rapid fruit growth and the fastest R R of coarse roots was immediately following fruit development. R S was estimated at 32.6 kg ha )1 d )1 (69% as a result of R R ) for the hottest month and at 7.6 kg ha )1 d )1 (18% as a result of R R ) during winter dormancy. Annual R S was low compared with other natural and cultivated ecosystems: 5.4 Mg ha )1 (46% as a result of R R ).• Our estimates of annual vineyard R S are the first for any horticultural crop and suggest that the assumption that they are similar to those of annual crops or forest trees might lead to an overestimation.

“…Root observation studies in grapevines have clearly indicated that root density (Daulta and Chauhan 1980;Southey and Archer 1988), root distribution (Bassoi et al, 2002;Morano and Kliewer 1994;Pradubsuk and Davenport 2011) and seasonal root growth dynamics (Bonomelli et al, 2012;Eissenstat et al, 2006;Mullins et al, 1992) are influenced by the soil environment (Callejas et al, 2009;Comas et al, 2010;Stevens and Douglas 1994), genotype (Swanepoel and Southey 1989) and aboveground phenology (Bonomelli et al, 2012). A significant number of studies have addressed root growth dynamics at weekly to seasonal time scales.…”

Diurnal root growth dynamics in mature grapevines

Six-year-old Shiraz vines were grown under field-like conditions in 780 L soil filled plastic bins. One year after transplanting, root growth was monitored non-destructively using minirhizotron tubes. Images of the roots were collected at sunrise, midday, sunset and midnight over six consecutive days during flowering. It was found that the vines displayed a diurnal dynamic in root growth with a maximum in the afternoon and evening, and a minimum in the morning. While it was not possible to separate the effects of time of day and soil temperature a positive relationship between soil temperature and root elongation was observed. The diurnal dynamics of root growth was consistent with earlier observations in young potted vines, and is the first indication that mature vines also exhibit a pronounced diurnal dynamic of fine root growth. The possible influence of carbon supply and the role of the circadian clock in these diurnal growth dynamics are discussed.

“…así como los niveles productivos de los huertos, sobre todo en las condiciones de temperatura de suelo del desierto de Atacama (Callejas et al, 2009), cuando existe una adecuada disponibilidad hídrica. Callejas et al (2012) ratifican para vides lo señalado por Sellés et al (2003), en el sentido que desde el punto de vista de funcionalidad y actividad, las plantas que presentan una tendencia a ser más productivas poseen raí-ces de menor diámetro y de color blanco, dado que las raíces menores a 2 mm de diámetro son las más importantes en términos de la absorción de agua y nutrientes (Mullins et al, 1992).…”

Foto: R. Callejas RESUMENLa vinaza, subproducto orgánico líquido de la fabricación del pisco, es catalogada en Chile como desecho industrial, generándose la necesidad de lograr su reclasificación y promover su uso como biofertilizante. Para esto, se propusieron tres experimentos entre los años 2010 y 2012, con el objetivo de definir dosis que no provocaran efectos negativos en el sistema radical, el crecimiento aéreo de las vides y características químicas del suelo. En los dos primeros experimentos se aplicó el equivalente a 0, 168, 336 y 672 m 3 ha -1 en la var. Pedro Jiménez, utilizando un rizotrón estrella de un 10,1 L de cuatro puntas (experimento uno) y maceta de 20 L (experimento dos). El tercer experimento se realizó en campo, var. Chardonnay, con cuatro tratamientos (0, 103, 206 y 412 m 3 ha -1 ) utilizando grupos de cuatro plantas como unidad experimental. En los dos primeros experimentos se definió que la dosis de 336 m 3 ha -1 no afectaban la parte aérea y promovía mayor crecimiento del sistema radical. En el experimento tres, cantidades de hasta 206 m 3 ha -1 no causaron cambios químicos a nivel de suelo o la parte aérea de la planta, pero promovieron un mayor índice de enraizamiento en los primeros 20 cm. El uso adecuado de la vinaza de pisco podría transformarse en una buena oportunidad para los pequeños agricultores, al utilizarse como enmienda orgánica o biofertilizante agrícola en viñedos. Palabras clave adicionales:Vitis vinifera, raíz, residuos agroindustriales, enmienda orgánica. and an experimental unit that corresponded to a group of 4 plants. In the first two experiments, a dose of 336 m 3 ha -1 did not affect the aboveground growth but promoted root development. In experiment 3, doses of up to 206 m 3 ha -1 did not change the chemical composition of the soil or the aboveground growth, but stimulated a higher rooting index in the first 20 cm of the soil profile. The appropriate use of vinasse, a byproduct of pisco, currently classified as an industrial waste, could provide a good alternative for grape growers when utilized as an organic amendment or biofertilizer in vineyards.
