“…Cysteine is the initial material for the production of reduced glutathione, which is responsible for detoxify cells through the elimination of free radicals and reactive species that accumulate during different types of stress (Saito, 2004;Zang, 2004). According to Tohbe et al, (1998), exogenous applications of reduced glutathione induced bud breaking on buds of grapevines of Cv. Delaware.…”

Problem statement:In warm-winter regions, the need for intervention of chemical means to break bud rest becomes a dominant factor for maintaining economic production of table grapes. However, the problem is more acute when farmers want to grow organic table grapes in the absence of environmentally-friendly budbreak promoters. Approach: This study aimed to evaluate the effect of a mix of naturally occurring Garlic Compounds (GC) in comparison to the conventional use of hydrogen cyanamide to promote budbreak and its effects on cluster quality in four table grape cultivars fieldgrown in hot region (Sonora Desert). Results: Four cultivars responded to GC, the vines bursting bud about 3 weeks after application. Quality of fruit from 4 cultivars treated with GC was excellent. Clusters weigh and berry sizes were larger than other treatments. Conclusion: Ability of GC to break dormancy in table grape grown in Sonora Desert has significant implications for organic table grape production in hot regions.

“…However, the latter decrease was accompanied by increased ethylene level. Increased level of endogenous ethylene was documented following heat treatment as well (Mizutani et al 1995;Tohbe et al 1998). While exogenous application of ACC enhanced dormancy release, it was reported that ethaphone and ethylene were unable to enhance dormancy release (Iwasaki 1981;Mizutani et al 1995).…”

“…It was therefore concluded that ethylene is not directly involved in bud break. Instead, it was suggested that cyanide, which is a byproduct of transformation of ACC to ethylene, is leading to bud break (Mizutani et al 1995;Tohbe et al 1998;El-Shereif et al 2005).…”

“…Increased level of ACC was recorded following controlled heat and chilling treatments that led to grape bud dormancy release (Tohbe et al 1998;El-Shereif et al 2005), but decrease was recorded following calcium cyanamide application that led to enhanced bud break as well (Mizutani et al 1995). However, the latter decrease was accompanied by increased ethylene level.…”

Gene-expression profiling of grape bud response to two alternative dormancy-release stimuli expose possible links between impaired mitochondrial activity, hypoxia, ethylene-ABA interplay and cell enlargement

A grape-bud-oriented genomic platform was produced for a large-scale comparative analysis of bud responses to two stimuli of grape-bud dormancy release, hydrogen cyanamide (HC) and heat shock (HS). The results suggested considerable similarity in bud response to the stimuli, both in the repertoire of responding genes and in the temporary nature of the transcriptome reprogramming. Nevertheless, the bud response to HC was delayed, more condensed and stronger, as reflected by a higher number of regulated genes and a higher intensity of regulation compared to the response to HS. Integrating the changes occurring in response to both stimuli suggested perturbation of mitochondrial activity, development of oxidative stress and establishment of a situation that resembles hypoxia, which coincides with induction of glycolysis and fermentation, as well as changes in the interplay between ABA and ethylene metabolism. The latter is known to induce various growth responses in submerged plants and the possibility of a similar mechanism operating in the bud meristem during dormancy release is raised. The new link suggested between sub lethal stress, mitochondrial activity, hypoxic conditions, ethylene metabolism and cell enlargement during bud dormancy release may be instrumental in understanding the dormancy-release mechanism. Temporary increase of acetaldehyde, ethanol and ethylene in response to dormancy release stimuli demonstrated the predictive power of the working model, and its relevance to dormancy release was demonstrated by enhancement of bud break by exogenous ethylene and its inhibition by an ethylene signal inhibitor.

A B S T R A C TViticulture is one of the most important economic activities in the Northwest of Mexico. A major obstacle for the economic production is the insufficient period of chilling temperatures. This problem leads to poor budbreak, which in turn results in reduced yields. This problem is aggravated when plants are cultivated using the organic farming system, mostly because there are not organically approved restbreaking agents. In this work different products derived from garlic (Allium sativum L.) were obtained and evaluated as stimulate budbreak agent of table grape (Vitis vinifera L.) cvs. Flame Seedless and Perlette. The isolated compounds were chemically identified and include allicin, diallyl disulfide, diallyl trisulfide, 3-vynil-[4H]-1.2-ditiin and 2-vynil-[3H]-1.3-ditiin, S-methyl cysteine sulphoxide, dimethyl disulfide, dimethyl trisulfide and dimethyl thiosulfonate. Cuttings with six buds were used to evaluate the compounds. After compounds were applied, the cuttings were transferred to a growing chamber at 24 °C. All evaluated compounds promoted budbreak in the cuttings of Flame Seedless and Perlette. The volatile compounds from S-methyl cysteine sulfoxide promoted 100% of budbreak of both cultivars. The compounds from garlic that stimulated budbreak in grapevines in this work include sulphur in their molecule; therefore we propose that sulphur could play a key role in breaking bud dormancy of grape cultivars evaluated in this study.
