“…Although berry ABA levels are not always dependent on leaf ABA levels during ripening (Okamoto et al 2004), the majority of ABA at veraison is transported from leaves to berries, where it accumulates. Thus, a significant increase in berry ABA during veraison has been reported in Cabernet Sauvignon and Ugni Blanc (Koussa et al 1993), and in field-grown non-irrigated Tempranillo (Antolín et al 2003). Similarly, our results also show this increase in berry ABA throughout veraison, reaching a maximum at the end of this period in all treatments ( Figure 5).…”

Our objective was to investigate whether grape berry growth and colour development is associated with variation in abscisic acid (ABA) levels during ripening under an irrigation regime of partial rootzone drying (PRD). The study was carried out using container‐grown Tempranillo grapevines (established as fruit‐bearing cuttings) with a split root system (occupying two contiguous pots) and grown under controlled conditions. Three irrigation treatments were imposed – a control (well watered), and two forms of deficit irrigation, viz. partial rootzone drying (PRD), and sustained deficit irrigation (SDI). Under SDI, a given volume of irrigation water was applied uniformly and simultaneously to both sides of the split roots of each vine. Under the PRD regime, the same total volume of irrigation was applied, but as separate allocations to each side of the split root system in turn, and alternating on a 10‐day cycle. Because both deficit treatments received the same total amount of irrigation water (about 50% of the volume applied to controls), we were able to distinguish between the effects of deficit irrigation per se, versus any specific impact PRD might be having on vine performance. Outcomes were as follows. Compared to well‐watered control vines, yield per plant, and weight per bunch were both reduced significantly under SDI, but were sustained close to control values under the PRD regime. SDI and PRD thus differed significantly in their respective impacts on vine performance, and comparing just these two forms of deficit irrigation, PRD resulted in greater yield, higher bunch weight, bigger leaf area and increased berry weight compared with the SDI treatment. Moreover, PRD also induced greater accumulation of skin anthocyanins at harvest, compared to SDI. Berry ABA concentration increased continuously throughout veraison, achieving a maximum at the end of this period. The increase of berry ABA concentration was earlier and faster in PRD than in SDI, which exhibited only a slight increase in berry ABA by the end of veraison. These distinctive responses to PRD compared to SDI imply that the alternating wet‐dry cycles of PRD, rather than simply a deficit irrigation, as in SDI, had a distinctive effect on growth, ripening and berry composition. Our data imply that these different responses might be related to ABA physiology, and especially to ABA levels in berries during ripening.

“…In the pericarp, the higher ABA concentration occurred when maximum size of berries was attained and in leaves, some days after the end of veraison. The changes of berry colour that occurred at veraison are also related to increased ABA content in all organs (seeds, pericarp and leaves) (Koussa et al 1993). Therefore, it is possible that ABA also influences anthocyanin accumulation (Kataoka et al 1982, Matsushima et al 1989).…”

“…Plant material (10-20 g) was crushed in methanol 80% containing BHT as an antioxidant. After filtration, the extracts were purified with PVPP (pH 3.0) and then a dialysis process was utilised to separate ABA-free and ABA-conjugates, as described by Koussa et al (1993). Finally, ABA determination was carried out by HPLC.…”

In grapevines, stomatal aperture decreases after a mid‐morning peak during summer days. Afternoon stomatal closure increases in non‐irrigated plants as water limitation progresses, which suggests the involvement of abscisic acid (ABA) in the control of stomatal aperture. The objective of this work was to study the seasonal and diurnal time‐courses of CO2 assimilation rate, leaf conductance, leaf water potential +, and ABA concentration in xylem sap, leaves, flowers and berries in non‐irrigated field‐grown Tempranillo grapevines throughout reproductive development. Leaf decreased throughout fruit development because water availability decreased towards the end of the reproductive cycle. CO2 assimilation rate, leaf conductance and xylem ABA concentration also decreased during the course of the growing season. Combining all measurements xylem ABA was either not correlated, or only slightly correlated, with leaf water status + and daily leaf conductance, respectively. This lack of relationship indicates that xylem ABA during fruit ripening had functions other than provision of a non‐hydraulic signal. On a seasonal basis, xylem ABA concentration measured in non‐irrigated grapevines was well related to berry ABA concentration, especially at the end of fruit development (veraison and harvest).

“…En effet, il est généralement admis que les feuilles, comme les racines, sont un lieu de synthèse privilégié de l'acide abscissique (JESCHEKE et al, 1997). Une partie de cet acide abscissique synthétisée dans les feuilles ou importée par ces feuilles depuis les racines migrerait vers les autres organes (HEIN et al, 1984;KITSAKI et al, 1995), phénomène que nous avons déjà signalé chez la vigne à l'époque de la véraison (KOUSSA et al, 1993). La diminution de la teneur en ABA des feuilles que nous avons signalée entre les stades H et J, concomitante d'une augmentation de la teneur en ABA-GE, suggère alors que ce régulateur de croissance doit être estérifié avant d'être exporté vers d'autres organes.…”

“…Chez la Vigne, l'ABA a été étudié plus particulièrement dans les fruits et leurs pépins en relation avec la véraison (BROQUEDIS, 1987;KOUSSA et al, 1993) et dans les bourgeons en relation avec la dormance (DÜRING et BACHMANN, 1975;KOUSSA et al, 1994). Il nous a donc semblé intéressant de suivre de façon précise l'évolution de l'acide abscissique sous ses deux formes: libre (ABA) et conjuguée (ABA-GE: abscissate de β-D-glucopyranose) dans les feuilles, les entrenoeuds, les boutons floraux, les fleurs et les baies du début de leur développement jusqu'au stade fermeture de la grappe.…”

Free abscisic acid (ABA) and bound abscisic acid (ABA-GE: ABA glucose ester) contents and growth were investigated in leaves, internodes, flowers buds, flowers and berries of Vitis vinifera L. cv. Cabernet Sauvignon between flower buds separated and grape closed stages. The ABA levels in leaves and in internodes decrease when the growth was hight and increases when the growth become smaller or stopped. What is more, ABA was accumulated hightly in the flowers (at 50% of flowering) and then appears to be a good marker of flowering. ABA contents decreased at berry setting and till grape closed stage. In leaves, internodes, flowers buds and flowers, ABAGE and ABA show an inverse development and then suggests an interconversion phenomenon between theses two forms. Two most importants points were discuted in this paper: 1) The role of ABA in the controle of growth and development of the organs studied and (2) The translocation of abscisic acid between the organs studied and the role of ABA-GE in this transport.
