“…In southern Brazil, it is normal to experience significant variation between years regarding the availability of cold during autumn and winter. As such, most cycles require the use of techniques to artificially overcome endodormancy, and chemical products, including hydrogen cyanamide, are used to "compensate" for the lack of winter cold (BOTELHO et al, 2010). Chemical management to overcome endodormancy presents substantial limitations concerning the technical tools used to make decisions regarding the need to exercise the control at the beginning of each cycle.…”

Fluctuations in winter chilling availability impact bud dormancy and budburst. This study aimed to quantify the thermal requirements during dormancy for ‘Italia’ grape, under different thermal regimes. Cuttings of grapevines ‘Itália’ were collected in Veranópolis-RS, on April/2017, with zero chilling hours (CH). The cuttings were exposed to constant (7.2°C) or alternating (7.2 and 18°C for 12/12h, 12/12h or 18/6h) temperatures, or yet, a constant temperature (7.2°C) or alternating (7.2 and 18°C for 12/12h), combined with one or two days a week at 25°C. Periodically, part of the cuttings was transferred to 25°C for daily budburst evaluation. The induction of the endodormancy (dormancy induced by cold) occurred with 200 CH, independent of the thermal regime, and the overcoming with 300 HF, at 7.2°C. The alternating heat of 18°C in the middle of the cold did not affect the process of overcoming endodormancy. Heat waves during endodormancy resulted in an increased CH to overcome the bud dormancy. The negative effect of high temperature depended on the exposure time. Chilling was partly cancelled during dormancy when the heat wave lasted 36 continuous hours or more. These evidences serve as basis for new model adjustments for budburst prediction, especially for regions with mild and irregular winters, such as those of Southern Brazil.

“…The active substances from garlic responsible for breaking bud dormancy in grapevines are sulfur-containing compounds containing an allyl group (CH 2 CHCH 2 ), particularly DADS. Many researchers have demonstrated that garlic extracts or the sulfur-containing compounds of garlic can improve bud break in grapevines (Kubota et al, 2003 ; Potjanapimon et al, 2008 ; Vargas-Arispuro et al, 2008 ; Botelho et al, 2010 ). Garlic and onion extracts can hasten floral bud break and increase the bud break percentage, fruit set, the total number of fruits and the fruit yield of apple trees; onion extracts can also stimulate the accumulation of total indoles (precursors for auxin synthesis) in “Anna” apple fruits (Botelho and Muller, 2007 ; Perussi et al, 2010 ; El-Yazal and Rady, 2014 ; Rady and El-Yazal, 2014 ).…”

Diallyl disulfide (DADS) is a volatile organosulfur compound derived from garlic (Allium sativum L.), and it is known as an allelochemical responsible for the strong allelopathic potential of garlic. The anticancer properties of DADS have been studied in experimental animals and various types of cancer cells, but to date, little is known about its mode of action as an allelochemical at the cytological level. The current research presents further studies on the effects of DADS on tomato (Solanum lycopersicum L.) seed germination, root growth, mitotic index, and cell size in root meristem, as well as the phytohormone levels and expression profile of auxin biosynthesis genes (FZYs), auxin transport genes (SlPINs), and expansin genes (EXPs) in tomato root. The results showed a biphasic, dose-dependent effect on tomato seed germination and root growth under different DADS concentrations. Lower concentrations (0.01–0.62 mM) of DADS significantly promoted root growth, whereas higher levels (6.20–20.67 mM) showed inhibitory effects. Cytological observations showed that the cell length of root meristem was increased and that the mitotic activity of meristematic cells in seedling root tips was enhanced at lower concentrations of DADS. In contrast, DADS at higher concentrations inhibited root growth by affecting both the length and division activity of meristematic cells. However, the cell width of the root meristem was not affected. Additionally, DADS increased the IAA and ZR contents of seedling roots in a dose-dependent manner. The influence on IAA content may be mediated by the up-regulation of FZYs and PINs. Further investigation into the underlying mechanism revealed that the expression levels of tomato EXPs were significantly affected by DADS. The expression levels of EXPB2 and beta-expansin precursor were increased after 3 d, and those of EXP1, EXPB3 and EXLB1 were increased after 5 d of DADS treatment (0.41 mM). This result suggests that tomato root growth may be regulated by multiple expansin genes at different developmental stages. Therefore, we conclude that the effects of DADS on the root growth of tomato seedlings are likely caused by changes associated with cell division, phytohormones, and the expression levels of expansin genes.

“…Moreover, Aguilaa et al (2015) reported that, Cabernet Sauvignon grapevines treated with garlic extract at 3.0 %, recorded the highest percent of burst buds (63 shoots plant -1 ), weight and the number of bunches per vine, whoever there were no differences in berry juice SSC%, titratable acidity and pH between garlic extract and Dormex treatments. Also spraying garlic extract on "Niagara Rosada" grapevines showed the similar results as usual treatments with CaCN 2 or H 2 CN 2 and it was effective in reducing the time for breaking buds dormancy and the period from winter pruning to harvest moreover, it increased cluster number per vine (Botelho et al, 2010). In the same trend, Corrales et al (2010) concluded that, garlic extract was effective in four table grape cultivars since it promoted bud breaking and advanced the fruit maturity by about three weeks and resulted in an excellent fruit quality.…”

“…Hydrogen cyanamide substance is the extensively used to stimulate bud break in vineyards. However, it is extremely toxic, where the Environmental Protection Agency of the United States classifies this substrate in the highly toxic (grade I= highest toxicity category) Botelho et al, (2010). In addition, using bud release synthetic chemicals considered an expensive cost and causes an environmental pollution.…”

This investigation was carried out during two seasons 2017 and 2018 on Flame seedless and superior seedless (Vitis vinifera L.) grapevines ten years old, grown in a private vineyard located at El-Beheira Governorate. The study was conducted to evaluate the potential effects of spraying with some natural substances (Garlic extract at 10 and 15% as well as Clove oil at 7 and 10%) as compared to artificial chemical treatment (Hydrogen cyanamide at 2.5%) usually used for breaking bud dormancy. The treatments were applied alone or combined with mineral oil at 2% two times (first week of January and one week later) in both seasons. The obtained results cleared that, the natural substances used, especially Garlic extract at 10 or 15% + mineral oil at 2% are resemble with Hydrogen cyanamide alone or with mineral oil at 2% treatment in hastening bud sprouting, shortening the duration of bud break, enhancing fertility coefficient, improving yield, cluster quality parameters (weight, length and width and berries per cluster), berries physical (weight, dimensions, volume) and chemical (SSC, SSC/acid ratio and anthocyanin contents of Flame seedless) quality parameters of both grapevine cvs. over control. Alternatively, Garlic extract can be used to safety release buds instead of that artificial chemical such as Hydrogen cyanamide.
