R. K. Striegler’s scientific contributions

... In recent years, studies have been conducted in the northern regions of the northern hemisphere to evaluate the benefits of using rootstocks for hybrid grape varieties grown in temperate and cold climates [5,[9][10][11][12]. Some studies have noted that rootstocks can affect the frost resistance of scions through a faster period of acclimatisation to cold [5,12,13]. In other studies, no differences in frost hardiness were observed depending on the rootstock in many scion/rootstock combinations [14,15]. ...

... Rootstock 3309 C had the most cold-hardy canes and buds; its acclimation in fall was faster, and de-acclimation in spring was slower than that in 5BB and SO4. Miller et al. (1988b) also found that different rootstocks affected the cold hardiness of scions grafted to them. For example, grafted 'White Riesling' was significantly harder than own-rooted vines. ...

Correction to: Abiotic Stresses and Rootstock Selection

... The effect of rootstock on the growth and resilience of the plant, its fruit production, and the composition and quality of the fruit and resulting wine is well documented. Rootstocks can improve vine performance and winegrape quality by regulating scion vigor (McCraw et al. 2005;Migicovsky et al. 2021;Reynolds and Wardle 2001;Sabbatini and Howell 2013;Tandonnet et al. 2010), addressing water stress (Striegler et al. 1993), imparting disease and pest resistance (East et al. 2021;Ferris et al. 2012), controlling uptake of specific nutrients (Gautier et al. 2020;Lambert et al. 2008;R€ uhl et al. 1988), improving winterhardiness (Gu et al. 2005;McCraw et al. 2005;Striegler and Howell 1991), and shortening the vegetative cycle to allow more veraison-toharvest heat units (Reynolds and Wardle 2001). Rootstocks can also influence juice quality (Gu et al. 2005;Main et al. 2002;Striegler et al. 2005;Vanden Heuvel et al. 2004) and ultimately wine quality (Krstic et al. 2005). ...

... Therefore, given the context-dependent nature of bud load effects on grapevine growth, yield, and berry composition, conducting region-specific research on diverse grape-growing scenarios is crucial. Pruning to a specific number of buds per unit of dormant pruning weight has been suggested as a method for achieving an optimal vine balance [2,20]. ...

... 'Karaerik' variety, being more vigorous in terms of vegetative development, would fall at the high end of the RI suggested for table grape varieties. In vines, a drop in yield also occurs after a few years, as over-crop loading on the vine will result in a decrease in bud yield (Miller et al., 1993). The main reason for this decrease in yield is thought to be related to poor light penetration into the canopy and/or vine allocation and photoassimilate production (Petrie et al., 2000). ...
