“…By considering FNF doses, a quadratic regression model significantly increased flowering percentage, as the maximum value of the function was of 43.7% open flowers at 2.2% ( Figure 2C Furthermore, different nitrogen forms in FNF can cause respiratory stress in the plant buds (SEGANTINI et al, 2015), which not only induces sprouting of vegetative buds, but also increases flower opening; therefore, a positive effect on plants productive traits.…”

“…In response to product application to overcome dormancy, the highest fruit number was also verified in 'Roxo de Valinhos' fig tree at 6% garlic extract, as produced more fruits in comparison to the other dosages . In 'Tupy' blackberry, Segantini et al (2015) recommend an estimated dose of 5.4% FNF, since it provided the highest fruit production (521 fruits plant -1 ), but doses higher than that reduced plant production. For 'Imperial Gala' apple, it is recommended to use doses below 7% Erger ® , as fruit reduction can happen above that value (HAWERROTH et al, 2010), besides increasing competition between vegetative and reproductive structures.…”

“…Among main products present in market to stimulate sprouting, hydrogen cyanamide is known as the most effective (SEGANTINI et al, 2015), but its high toxicity have been restricted in many countries (LEONEL et al, 2014). Such restriction has stimulated the search for other compounds to induce sprouting in temperate fruits, such as potassium nitrates (ELSABAGH, 2014); calcium (NACHTIGALL;CAMELATTO, 1997); mineral oils (OLIVEIRA et al, 2008); and garlic extracts (OLIVEIRA et al, 2009).…”

Several authors have reported FNF efficiency in promoting sprouting and flowering in some temperate fruits, such as kiwi (HERNÁNDEZ; CRAIG, 2011); blackberry (SEGANTINI et al, 2015); and apple (HAWERROTH et al, 2010). Further studies are necessary to determine the best product doses in other temperate fruits to become a feasible option for fruit growers.…”

Choosing cultivars that require less chilling temperatures to overcome dormancy is crucial, for example, peaches that grow in subtropical areas, which is not an appropriate climate for them. Thus, alternative techniques are necessary to induce sprouting. Yet there are not many available products in market, restricting options for fruit growers to a reduced number of chemical molecules, which are often harm the health to applicators. Therefore, this study aimed to assess phenological cycles and productive performance of three peach cultivars, submitted to foliar nitrogen fertilizer and calcium nitrate to induce sprouting. This study took place at Experimental Orchard of School of Agriculture (FCA, UNESP), Botucatu, state of São Paulo. Three peach cultivars were evaluated: 'Douradão', 'BRS Kampai' and 'BRS Rubimel' by applying four doses of foliar nitrogen fertilizer (FNF) at 0, 1.25, 2.50 and 3.75%; associated with 4% calcium nitrate. A 3x4 factorial arrangement (3 cultivars X 4 FNF doses) in a randomized block design was used, with 4 replicates and 2 plants per plot, totalizing 96 plants. Results indicated that FNF positively affected cultivars development, providing wider sprouting, flowering and fruit set; consequently, greater production. Then FNF became a good alternative to induce sprouting in peaches at mild winter temperatures. Moreover, 'BRS Rubimel' presented high sowing percentage associated with low flowering and fruit set percentages, that is, low production mainly caused by its lack of adaptability to studied region.

“…Preliminary studies have identified a commercial product called Erger ® as a less dangerous option to stimulate budburst in temperate fruit species. According to manufacturer's guidelines, this product is an organic nitrogen compound which, when mixed with calcium nitrate (Ca(NO 3 ) 2 ), has budbreaking effects on apples (HAWERROTH et al, 2010b; PETRI et al, 2014 and blackberries (SEGANTINI et al, 2015). Therefore, this product could be an alternative with lower environmental risk for dormancy control in the Campanha Gaúcha region.…”

Seeking a less toxic alternative to budburst management than hydrogen cyanamide, doses of the mineral-organic product Erger® were tested in combination with calcium nitrate (Ca(NO3)2). The experiment was conducted in Santana do Livramento, southern Brazil, during the 2013/14 and 2014/15 growth cycles, in a ‘Merlot’ vineyard conducted in a vertical trellis system, pruned in double Guyot, with SO4 rootstock. Treatments were: Control (unsprayed); 5.0% Ca(NO3)2; 2.5% Erger® + 5.0% Ca(NO3)2; 5.0% Erger® + 5.0% Ca(NO3)2; 7.5% Erger® + 5.0% Ca(NO3)2; 3.5% Dormex® (positive control). All Erger® treatments stimulated budbreak, increasing budburst from 68% (unsprayed and calcium nitrate means) to 83% (Erger® means) in the first cycle and from 85% to 96% in the second one, with no difference among doses. Plants treated with Dormex® had budburst similar to Erger® in the first cycle (85%), but budburst in the second cycle was only 72%, possibly due to burned buds. Therefore, Erger®, in concentrations of 2.5% or more with 5% calcium nitrate, may be a promising alternative to induce budburst in regions with restrictions in cold availability.

Short growing season is one of the main obstacles to the commercial production of grapes in regions experiencing cold/semi-cold climates. This is known to impact the quality and quantity of production. Consequently, this study was conducted to evaluate the effects of foliar application of hydrogen cyanamide (Dormex) solution (0, 1%) as a rest-break agent and its physiological and biochemical mechanisms, on 10-year-old Askari grape (Vitis vinifera 'Askari') trees, in a completely randomized block design in a factorial combination with three replications. The results showed that catalase activity was lower in the samples treated with hydrogen cyanamide solution (1%) compared to the untreated buds during the second, third, and fourth sampling dates, and hydrogen peroxide accumulated in the buds during the same period. Putrescine concentration was increased more than 6 folds in hydrogen cyanamide treated (1%) samples during the bud dormancy release period compared to the rst sampling date, while spermidine and spermine concentration showed a signi cant decrease (about 90% and 80% respectively). Hydrogen cyanamide treatment also resulted in increased total nitrogen concentration in buds due to a rise in amino acids' concentration (proline, glutamine, arginine, ornithine, and citrulline). In conclusion, the current ndings showed that the hydrogen cyanamide application enhanced bud break by 7.78% and 6.67%, 20 and 30 days after hydrogen cyanamide solution spray application, respectively.
