“…The vines were grafted on R110 rootstock, planted with 2 m 9 3 m spacing on a sandy soil (pH = 7.5) and trained onto a two-wire trellis. We estimated the variety's chilling requirement to be about 440 chill units (Ben Mohamed et al 2010a). The vines were pruned to four spurs and four long canes with an average of 16 buds each at mid-November.…”

“…Endodormancy, coinciding with winter, is an inhibition controlled from within the bud itself and released upon exposure to chilling. Hence, to resume growth, tree bud must receive an amount of chilling which is genetically controlled and varies among genotypes (Balandier et al 1993;Egea et al 2003). However, in mild-winter climates, most deciduous trees suffer from the lack of chilling which prolongs dormancy and triggers abnormal patterns of budbreak and development leading to low commercial production (Erez 1995).…”

“…Polyamines are low molecular weight nitrogenous compounds that are abundant in all living organisms. Higher plants possess high levels of the polyamines putrescine, spermidine and spermine (Ben Mohamed et al, 2010). Polyamines are biologically active compounds involved in various physiological processes in the cell, including the regulation of development, morphogenesis and plant cell growth (Hanzawa et al, 2000), and they also reduce the negative impact of salinity on plant growth (Kamiab et al, 2014).…”

Gladiolus is one of the most popular cut flowers in the world floral market and is highly attractive to consumers. The production of poor-quality gladiolus spikes is one of the most important hurdles to obtaining high prices for this crop. The main objectives of this study were to improve the quantitative characteristics of gladiolus spikes, to increase propagule production and to enhance chemical constituent levels in leaves to help improve plant growth. We performed foliar application of bioregulators, including polyamines (putrescine and spermine) and vitamins (ascorbic acid and thiamine), at different concentrations (0, 0.1, 0.4, 0.7 and 1 mM) to gladiolus plants at the three leaf, five leaf and slipping stages. Application of 1 mM putrescine was the most effective treatment, with prominent effects on economically important spike traits including spike length (55.53 cm), spike diameter (7.53 mm), florets per spike (13.99), first floret diameter (9.66 cm) and first floret weight (4.90 g), followed by spermine treatment. The 1 mM putrescine treatment also had positive effects on corm-associated traits including corm diameter and corm weight, with values of 4.57 cm and 26.16 g compared to 3.47 cm and 17.16 g in control plants, respectively. The contents of chemical constituents in leaves, including total chlorophylls (8.06 mg･g -1 ), total carotenoids (1.66 mg･g -1 ), total soluble sugars (4.75 mg･g -1 ) and phenolics (0.89 mg･g -1 ) increased in response to foliar application of 1 mM putrescine compared to the control. Ascorbic acid and thiamine also had positive effects on various plant morphological traits and chemical constituents in leaves compared to control plants, but the growth-promoting effects of polyamines were more pronounced. Hence, applying polyamines to gladiolus leaves will help improve spike production and increasing propagule (cormel) yields.

In this study, we investigated the cumulative effect of low temperature on bud dormancy release and bud break characteristics in 'Campbell Early' grapevine (Vitis labruscana B.) cuttings grown in water culture. Additionally, we observed the development of buds while exposed to low temperatures in an attempt to improve our understanding of dormancy and bud break. The shoots were collected 120 days after full bloom (DAFB; leaf abscission period), and the accumulated chill unit (CU) value was calculated by reducing the temperature to 7.2°C at 125 DAFB. The rate of bud break was 100% in shoots collected at 150 DAFB, The period until the first bud break was two times longer than in the shoots collected 165 DAFB, and bud break speed was significantly reduced. These results indicate that buds are released from endodormancy after 165 DAFB, because at this point the bud break was complete (bud break rate 100%) and it occurred in a very short time period. During this period, when the low-temperature accumulated value was 321h and 442CU according to the CH and Utah models, respectively. Furthermore, the survival rate of main buds decreased rapidly after 165 DAFB, and survival rate of accessory buds was maintained at more than 90% without seasonal differences. The rate of flower bud formation of main buds was much higher than in accessory buds (1:0.23) before the release from endodormancy at 150 DAFB. The final ratio of accessory buds to main buds was high, 1:1.54, at 255 DAFB. Correlation analysis of each investigated factor revealed that bud survival rate and bud formation rate were related only for the main buds, and there was a close relationship between the survival rate of main bud and time. In addition, the survival rate of main buds was positively correlated to the rate of flower bud formation. et al., 1984;McColl,
