Effects of rootstock genotypes on compatibility, biomass, and the yield of Welschriesling

Abstract

Vršič S., Pulko B., Kocsis L. (2016): Effects of rootstock genotypes on compatibility, biomass, and the yield of Welschriesling. Hort. Sci. (Prague), 43: 92-99.The aim of this work is to determine the compatibility, the scion biomass, and the yield of the grapevine variety Welschriesling grafted onto 12 grapevine rootstocks. As an index of compatibility, the callus development and graft success were determined. Dry weight of canes was measured at the end of the growing seasons (2011)(2012)(2013)(2014), while root dry weight only in the first year in the nursery. The grape yield was measured in the first production year. Welschriesling showed good compatibility with all examined rootstocks. More than 85% of grafts had a complete callus development (8BČ rootstock 100%). The average of graft success in the nursery was 67%, but the average of 5BB, G251, and G103 was above 80%. The G103 rootstock had the highest root dry weight after one season. The dry weight of canes in vineyards was above the average with 5BB, SO4, Binova, Börner, and M V rootstocks. All Georgikon rootstocks had a lower cane dry weight per vine than the others. The highest yields were recorded on SO4, G251, and Börner rootstocks.

A Phenotypic Search on Graft Compatibility in Grapevine

“…Much effort has been dedicated to the search of physiological [11,17], metabolic [18,19,46], and molecular [5,21,22] markers to predict in an early growth stage graft compatibility in grapevine with the aim of improving rootstock selection and propagation. To reveal grafting-related physiological symptoms that might enable nurseries to predict whether a graft combination is likely to succeed, we applied several methods at two time points (21 DAG and 152 DAG) to score graft compatibility of graft combinations known to show distinct compatibility behavior [5,18,19,23].…”

“…Inline, predictive and standardized measurements to evaluate compatibility levels would be useful for breeders when considering the use of a rootstock with a specific graft combination [3], particularly in the case of new genotypes under selection with unknown grafting properties [8][9][10]. Indeed, to release a new grapevine rootstock into the market, several traits need to be evaluated including "Phylloxera" and nematode resistance, salt and drought tolerance, and last but not least, graft compatibility with scion species need to be assessed [11].…”

Short Communication: Variations of morphology, anatomy, and metabolite profiles of Citrus reticulata Blanco cv. Tawangmangu grafts produced by shoot tip grafting using several rootstocks

“…Citrus and other commercial fruit trees are usually cultivated as grafted trees with a selected rootstock. This technique offers many benefits including an increase in product quality and yield (Vršič et al 2016), increase the resistance against pathogens and abiotic stresses (Ramírez-Gil 2018; Zhou et al 2018), reductions in the period to fruiting through increasing precocity, avoidance of a juvenile state (Baron et al 2019), and gain specific characters from the scion such as dwarfing to facilitate maintenance and harvesting (Hartmann et al 2011).…”

Determination of Sapling Yield and Quality Characteristics of Grape Varieties Grafted on Different Rootstocks

“…Farklı anaç-çeşit kombinasyonlarının denendiği birçok çalışma [16,17,18,19,20,21] mevcuttur. Yapılan bu çalışma ile farklı anaçlar üzerine aşılı şaraplık üzüm çeşitlerinde fidan randıman ve kalite özelliklerinin belirlenmesi amaçlanmıştır.…”

“…Bu nedenle anaçların ve çeşitlerin fizyolojik özelliklerinin bilinerek uygun anaç-çeşit kombinasyonunun seçilmesi oldukça önemlidir [15]. Ayrıca, anaçlar çeşidin ekonomik, karakteristik ve biyokimyasal özelliklerini de etkilemekte anaç-çeşit kombinasyon ilişkisi, toprak ve iklim özellikleri ile de son derece alakalı olmaktadır [16]. Aşılı asma fidanı üretimi birçok basamaktan oluşmaktadır ve bu aşamaların her biri fidan randıman ve kalite parametrelerini önemli derece de etkilemektedir.…”
