“…Increased cutting length has been observed to affect rooting in other fruit crops (Aljane and Nahdi, 2014;Wainwright and Hawkes, 1988), although the correlation between cutting length and rooting success is not always positive as it was in this study (Exadaktylou et al, 2009). Our results also support previous findings on the association of increased cutting diameter and higher rooting success (Castro et al, 1994;Goode et al, 1982). The differentiation of rooting ability based on cane position is well documented in both other Vitis species and other woody plant species (Hartmann et al, 1997;Keeley et al, 2004).…”

“…(Daskalakis et al, 2018;Keeley et al, 2004). To date, a single study has directly investigated the effect of cane position on rooting in muscadines and observed moderately increased rooting success in cuttings taken from basal positions on the cane (Castro et al, 1994). Although not directly comparable to cane position, Goode et al (1982) saw increased rooting in cuttings with larger diameters.…”

Rooting hardwood cuttings from muscadine (Vitis rotundifolia Michx. syn. Muscadinia rotundifolia) vines has traditionally been considered an exceptionally difficult task. Many previous studies observed almost no root formation, leading to a general consensus that muscadines should either be propagated by softwood cuttings or vegetative layering. However, the University of Arkansas System Division of Agriculture Fruit Breeding Program has been using a hardwood rooting protocol for muscadines with moderate success for the past 10 years. The application of this protocol to meet the modest propagation needs of the breeding program has significantly shortened the time required to advance selections. The goal of this research was to more adequately describe the factors affecting the rooting ability of hardwood muscadine cuttings. This research investigated the effects of cultivar, bottom heat, cold storage, vineyard location, and cutting collection date on the outcome of muscadine hardwood cuttings. The study was conducted during the dormant seasons of 2019–20 and 2020–21, and an overall rooting percentage of 16% was observed. There were multiple higher-order interactions affecting rooting efficacy. Cuttings taken in November generally rooted at higher rates, although interactions with vineyard location and cultivar played a significant role in those results. The Ocilla, GA, location performed exceptionally well in November with rooting percentages greater than 40%. The effects of supplying bottom heat and/or a cold storage treatment on rooting success declined as the dormant season progressed. Other variables such as increased cutting length and diameter were associated with increased rooting success. A second statistical analysis using only data from November showed that when cuttings were not given a cold storage treatment that rooting percentages were greater than 27%. Ultimately, this research shows that institutions with modest muscadine propagation needs can successfully propagate plants from hardwood cuttings.

“…In their investigations to assess the usefulness of IBA application to the cuttings of some grape varieties and rootstocks, Daskalakis et al, 2018 [7]; Doğan et al,2016 [8]; Galavi et al, 2013 [9] documented that IBA treatments at specific concentrations improved rooting percentage, number of roots on cuttings, and root length. On the contrary, other studies showed that exogenous auxins can have no significant improvement or even inhibit the rooting process of grape cuttings [10,11,12].…”

Rooting stimulation of “Victoria” and “Korinka russkaya” grape hardwood cuttings as influenced by potassium salt of Indolyl-3-Acetic Acid (KIAA)

Relevance. Applying exogenous auxins to the cuttings of grapevines is a common practice in viticulture to improve the rooting process. The potassium salt formulations of auxins have been documented to be more, less, or equally efficient as acid formulations in rooting stimulation of cuttings depending on the genetic features of the plant, type and concentration of auxin, type of cuttings, and many other factors.Methods. The present study aimed at evaluating the effect of potassium salt of indolyl-3-acetic acid (KIAA) on rooting of the hardwood cuttings of two grape cultivars namely, Korinka russkaya and Victoria, which are commonly planted by grape growers of the Tatarstan Republic. The study was conducted in 2018 and 2019 under hydroponic conditions in a controlled-environment growth chamber in Kazan State Agrarian University. The cuttings were treated with 1) KIAA at two concentrations (5,000 and 10,000) ppm; 2) β-indolyl-butyric acid (IBA) 3,000 ppm (as a check treatment) and 3) distilled water as a control.Results. Based upon the overall results, KIAA significantly improved the rooting process of both investigated cultivars. Rooting percentage, average number of roots on cuttings as well as the quality of the root system was enhanced with increasing auxin concentration up to 10,000 ppm. IBA also improved the rooting quality parameters over the controls. The two grape cultivars differed significantly in their rooting capacity: cuttings of Korinka russkaya in both years had greater values of all the studied parameters compared with those of Victoria cultivar except for the callusing percentage, which was higher in Victoria.

A simple, rapid, and quantifiable system for studying adventitious root formation in grapevine

et al. 2022

Woody cutting is customarily utilized as material in research of grape adventitious root formation (ARF).However, phenotypic heterogeneity caused by the complex background in uenced its use for molecular mechanism research of ARF of grape. The present study tested various types of explants from grape tissue culture plantlets and found the whole leaf: blade with petiole (LP) was the simplest unit that can easily form adventitious root (AR). LP explants which can be easily obtained, directly generate ARs via de novo organogenesis from the base of the petiole. The plantlet age, node position, blade size, the health condition of leaves, and light intensity have been demonstrated to affect the homogeneity of ARF phenotype in LP. By controlling these parameters, selected LPs cultured on medium with 6 g•L -1 agar and 10 g•L -1 sucrose under dark conditions started rooting at 6-7 day after culture (DAC) and reached 100% rooting rate within 13-14 DAC. Using this system, the core role of auxin on ARF was veri ed by exogenous application of indole butyric acid (IBA) and N-1-naphthylphthalamic acid (NPA). Strikingly, we found light promoted ARF in the absence of sucrose, but inhibited ARF in the presence of sucrose (10 g•L -1 ), while a low concentration of 0.1 mg•L -1 NPA partially relieved the inhibition. Finally, this study con rmed exogenous plant growth regulators (PGRs), including 6-benzyl aminopurine (6-BA), gibberellic acid 3 (GA 3 ), and 2,4-Epibrassinolide (EBR) inhibited ARF signi cantly. This simple, rapid, quanti able ARF research system provides a new approach to study the factors in uencing the formation and development of grape adventitious roots and establishes a framework for investigating the mechanism of grape adventitious root induction and initiation.
