“…Sufficient cold conditioning or chilling exposure received by strawberry during the late autumn and winter helps the plants to adapt and grow in the temperate region (Durner et al 1984;Maas 1986). Meanwhile, inadequate chilling results in low vegetative vigor and reduced vegetative growth, flowering, and fruiting of strawberry (Voth & Bringhurst 1970;Craig & Brown 1977;Robert et al 1997;Bringhurst & Galletta 1990). Plants with low vegetative vigor flower intensely and produce small fruit (Bringhurst & Galletta 1990).…”

The influence of chilling period hours and accumulative photo-thermal unit at different base temperatures, 10, 11, 13, 15, and 18 °C, on the flowering of strawberry was examined in Sana’a University-Yemen during two seasons: 2006 and 2007. The randomized complete block design (RCBD) field experiment was designed with 5 chilling hours (CHs) periods (0, 360, 750, 1080, and 1440 CHs under 2 ± 1 °C), with four replicates each. Accumulative photo-thermal unit (PTU) was calculated for every treatment at different base temperatures for two stages: (i) from planting date to the flower opening (THA) and (ii) from planting date until the end of 2 months (THB). The results revealed that the plants treated with 1080 h of chilling produced flowers with about 55.12% and 61.97% earlier when compared with control (without chilling) in both the seasons, respectively. Stepwise multiple regression analysis showed that both CHs and the accumulative PTU THA13 (in the first season) and CH plus THA10 (in the second season) have significant effect on days until flower opening, in which the majority effect was related to the chilling period. The effect of chilling period and accumulative PTU at 18 °C (THB18) had s significant influence (p < 0.05) on the number of early flower per plant, with about r2 = 0.250 and r2 = 0.536 in both the seasons, respectively, and r2 = 0.531 and r2 =0.740 for the total effect of both CH and THB18, respectively. However, the exposure of plants to the long period of chilling (1080 and 1440 h) led the plants to produce runners and break up the flowering stage after 9 and 11 weeks in both the seasons, respectively. Meanwhile, plants that received 360-h chilling produced significantly highest (p < 0.05) total number of flowers (24.83 per plant), with about 71.2% higher than that produced by control plants. Moreover, in the second season, plants treated with 750-h chilling produced the significantly higher total number of flowers per plant, with about 50.3% higher than that of the control. Meanwhile, the 360-h and 750-h chilling periods have similar effect on the number of flowers per plant in the second season. The result showed that the starch level in the crown significantly positively correlated with the days to flower opening (r2 = 0.415, p = 0.05) and negatively correlated with the number of early flower (r2 = 0.587, p = 0.01). The data from this study might be used for the management of strawberry production.

“…Inadequate (insufficient) chilling results in decreased plant vigour and reduced fruiting. However, excessive chilling may lead to delayed initiation of new flowers and reduced fruit yield [Voth and Bringhurst 1970, Craig and Brown 1977, Bringhurst and Galletta 1990, Robert et al 1997, Meulenbroek and Lieten 2021.…”

The chilling requirements of two strawberry cultivars (‘Sonata’, ‘Albion’) were assessed by evaluating the starch accumulation levels in the tray plants’ root system and their subsequent growth and yielding. The research was conducted in an experimental orchard and a greenhouse of the National Institute of Horticultural Research in Skierniewice, Poland, in 2017–2019 (2 cycles of obtaining planting material and growing plants). The tray plants (rooted tips) were grown in the natural field conditions until they were transferred in batches to a cold store (–2°C) on five different dates: 12 Oct., 30 Oct., 20 Nov., 11 Dec., and 3 Jan. (of the following year). The number of accumulated chilling hours less than 7°C was recorded for each transfer date, and the roots were analysed for starch content at the time of transfer. After the end of cold storage (3 months, standardised for all treatments), the plants were planted in pots and transferred to a greenhouse to assess growth and plant yielding. The obtained results indicate that chilling induces changes in the extent of starch accumulation. The highest starch accumulation in ‘Sonata’ roots was recorded when the plants received about 500 h of chilling (under Polish conditions accumulated in November/December). In the ‘Albion’ strawberry case, the maximum was found at the lower chilling level – about 300 h (middle of November). The highest fruit yields were produced by ‘Sonata’ plants, for which the number of chilling hours (0–7°C) was 500–800 h. In the case of ‘Albion’, the values were 2–3 times lower. A more extended period of keeping tray plants in field conditions (over 1000 h of chilling) resulted in a deterioration in fruit yield.

“…Atualmente, as mudas são classificadas e comercializadas para o plantio somente pelo diâmetro na base da planta (rizoma). A constante procura por outros parâmetros que auxiliem nesta classificação se faz necessária, pois os métodos até hoje utilizados, como a medida dos teores de nucleotídeos (Robert, 1996) e o teste biológico (Robert et al, 1997), mostram alguma impertinência no seu emprego rotineiro.…”

“…Para verificar as diferenças do potencial de crescimento do morangueiro, utiliza-se atualmente de um teste biológico conhecido como teste do pecíolo (Robert et al, 1997). Este teste é baseado no crescimento dos pecíolos das folhas em condições climáticas adequadas ao crescimento (temperatura e fotoperíodo), onde o menor desenvolvimento dos pecíolos indicaria a diminuição do potencial de crescimento, enquanto o maior crescimento dos pecíolos indicaria a retomada do potencial de crescimento.…”

“…Contudo, é difícil deduzir se este aumento inicial dos valores se trata do fim da saída da dormência que não teria terminado no momento da entrada das plantas em câmara fria. Na verdade, o tamanho do pecíolo está em nível considerado alto (durante o período de plena endodormência, por exemplo, o tamanho do pecíolo pode ficar muito menor, podendo chegar a mais ou menos 3 cm (Robert et al, 1997). Por outro lado, as variações observadas não apresentaram diferenças significativas.…”

The aim of this work was to know the physiological state of the aerial part of strawberry plants (varieties Gariguette and Elsanta) during storage in cold chamber (-2ºC) from January until August. According to the biological test (petiole test), the growth capacity was kept up without significant evolution. The flow of metabolic heating (Q) and the respiratory intensity (RCO2) of the apical zone tissues measured at the exit of the cold chamber did not change significantly. Their values measured after 48 and 72 hours of acclimatization at 20ºC were higher than at the exit of the cold chamber. The differences between the values without acclimatization and after acclimatization increased during the first weeks of storage, showing an evolution in the apex of the plant. There was a strict parallelism between the values of Q and RCO2 and of the tissues water contents (UP). The growth capacity of the aerial part of the plants seemed to keep up even after 8 months of storage
