Soil fertility and confered vigour by rootstocks


The adaptation of rootstock to scion variety and soil determines largely the control of the vegetative growth for grapevine. Many experiments were performed in the vineyard to classify the rootstocks according to their soil adaptation and to their effect on vine vigour. So far there are no data describing the course of appearance of rootstock effects after plantation. Moreover the underlying mechanisms of conferred vigour remain largely unknown. An experimental vineyard was planted with 2 varieties (Merlot and Cabernet-Sauvignon) grafted onto 3 known rootstocks (Riparia Gloire de Montpellier, SO4 and 110R) in a gravely soil from Bordeaux area. Two years after plantation, a high level of soil fertility was created on half of the plot, by adding 100 N units at spring and watering the vines during summer. Soon after plantation and during 4 years, developmental data (phenological stages, shoot growth, shoot diameter, leaf area, pruning wood weight, bud fertility and yield) and physiological data (water status, leaf gas exchanges, mineral analysis, stored carbohydrates) were collected all through the seasons.

It was observed that the rootstocks affected vine vegetative growth early after plantation, before the vines bared any crop and even in the plot where the fertility was high. Parameters describing vegetative growth (shoot growth rate, shoot diameter, leaf area) and biomass accumulation were highly correlated. Significant differences between rootstock / scion combinations were recorded on leaf gas exchanges, stored carbohydrates and water status. However these effects are closely related to the vegetative and reproductive development of the vines. Multidimensional analysis of the data showed the effects of scion variety, rootstock and soil fertility. The invigorating effect of Riparia Gloire de Montpellier remains regardless of soil fertility and scion variety. However this effect is stronger when the scion is Cabernet-Sauvignon. The conferred vigour seems to be related to a very early interaction between rootstock and scion, which occurs regardless of environmental conditions. The determinism of this interaction does not seem to be related to the water and nitrogen status of the vines.

Physiological and growth reaction of Shiraz/101-14 Mgt to row orientation and soil water status

Advanced knowledge on grapevine row orientation is required to improve establishment, management and outcomes of vineyards on terroirs with different environmental conditions (climate, soil, topography) and in view of a future change to more extreme climatic conditions. The purpose of this study was to determine the combined effect of row orientation, plant water status and ripeness level on the physiological and viticultural reaction of Shiraz/101-14 Mgt.

Effects of mechanical leafing and deficit irrigation on Cabernet Sauvignon grown in warm climate of California

San Joaquin Valley accounts for 40% of wine grape acreage and produces 70% of wine grape in California. Fruit quality is one of most important factors which impact the economical sustainability of farming wine grapes in this region. Due to the recent drought and expected labor cost increase, the wine industry is thrilled to understand how to improve fruit quality while maintaining the yield with less water and labor input. The present study aims to study the interactive effects of mechanical leafing and deficit irrigation on yield and berry compositions of Cabernet Sauvignon grown in warm climate of California.

The effects of cane girdling on berry texture properties and the concentration of some aroma compounds in three table grape cultivars

The marketability of the table grapes is highly influenced by the consumer demand; therefore the market value of the table grapes is mainly characterized by its berry size, colour, taste and texture. Girdling could cause accumulation of several components in plants above the ringing of the phloem including clusters and resulting improved maturity. The aim of the experiments was to examine the effect of girdling on berry texture characteristics and aroma concentration.

Application of a fluorescence-based method to evaluate the ripening process and quality of Pinot Blanc grape

The chemical composition of grape berries at harvest is one of the most important factors that should be considered to produce high quality wines. Among the different chemical classes which characterize the grape juice, the polyphenolic compound, such as flavonoids, contribute to the final taste and color of wines. Recently, an innovative non-destructive method, based on chlorophyll fluorescence, was developed to estimate the phenolic maturity of red grape varieties through the evaluation of anthocyanins accumulated in the berry skin. To date, only few data are available about the application of this method on white grape varieties.

Different yield regulation strategies in semi-minimal-pruned hedge (SMPH) and impact on bunch architecture

Yields in the novel viticulture training system Semi-Minimal-Pruned Hedge (SMPH) are generally higher compared to the traditional Vertical Shoot Positioning (VSP). Excessive yields have a negative impact on the vine and wine quality, which can result in substantial losses in yield in subsequent vintages (alternate bearing) or penalties in fruit quality. Therefore yield regulation is essential. The bunch architecture in SMPH differs from VSP. Generally there is a higher amount but smaller bunches with lower single berry weights in SMPH compared to VSP.
