Berry shrivel causes – summarizing current hypotheses

Abstract

Diverse ripening disorders affect grapevine resulting in high economic losses worldwide. The common obvious symptom is shriveling berries, however the shriveling pattern and the consequences for berry quality traits are distinct in each disorder. Among them, the disorder berry shrivel is characterized by a reduced sugar accumulation short after the onset of berry ripening leaving the clusters unsuitable for wine processing. Although our knowledge on BS increased recently, potential internal or external triggers contributing to the induction of BS are yet to be explored. Based on previously obtained results, we speculate on three main hypotheses for future research: i) BS starts with a failure in phloem unloading of sugar and its metabolism in berry cytosol, ii) the brush area of berries is subjected to a premature cell death starting BS and further promotes programmed cell death in other berry areas and pedicels, and iii) the onset of berry ripening is disturbed either by phytohormone or other signals with consequences on sink strength. Sampling strategies need to be adapted to account for ripening asynchrony and include pre-symptomatic clusters. Additionally, innovative ideas and new methodological approaches are necessary to decipher the spatial and temporal factors in BS induction on the biochemical, transcriptional and morphological level. BS is a challenge for viticulture, as prevention strategies are currently not reliable. Identifying the causal events could facilitate to adapt vineyard management to reduce BS risks.

Characterizing graft union formation in different scion/rootstock combinations of grapevine 

In most viticultural regions, grapevines are cultivated grafted, employing either hybrid or pure species of various American Vitis spp., such as V. berlandieri, V. rupestris, and V. riparia, as grapevine rootstocks. These rootstocks play a crucial role in providing resistance to the Phylloxera insect pest. Beyond Phylloxera resistance, it is desirable for grapevine rootstocks to exhibit resistance to other soil-borne pathogens and adaptability to abiotic stress conditions. The introduction of new rootstocks holds promise for adapting agriculture to climate change without altering the characteristics of the final harvested product.

Training system and its influence on iso-anisohydric behavior of cv. Syrah

Water use efficiency is one of the most valued objectives in vine growing in mediterranean climates (de la fuente et al., 2015). Due to this, the grape growers provide different adaptation strategies according to their efficient consumption against the presumable water deficit generated under these environmental conditions. The use of non-positioned shoot systems (like sprawl, bush, etc.) Can help to achieve this objective.
