“…However, the exposure to chilling for 1080 or 1440 hours changed the behavior of this cultivar to grow like Junebearing by producing runners (Table 8). Strawberry plants exposed to plenty of chilling produced many runners (Guttridge 1969;Bringhurst et al 1960;Porlingis & Boynton 1961;Bailey & Rossi 1965;Piringer & Scott 1964;Braun & Kender 1985;Kahangi et al 1992;Risser & Robert 1993;Lieten 1997;Tehranifar et al 1998;Bigey 2002;Hokanson et al 2004;Taghavi & Aghajani 2017). Longer durations of chilling lead to the shorter flower differentiation (Lieten 2006).…”

“…____________________________________________________________________________________________________________________ Meanwhile, if the strawberry plant did not receive the satisfactory amount of chilling, the growth will be sluggish and would not form high fruits (Smeets 1982;Yangagi & Oda 1992). Tehranifar et al (1998) found the field chilling was more effective than that carried out using cold storage in the dark. Meanwhile, F. × ananassa does not true dormancy as observed with most members of the Rosaceae, where the short-day cultivars adapted to cool winters will grow in the tropical regions, and the full production will be achieved by required chilling (Arney 1956).…”

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.

“…Once dormancy is initiated, sufficient winter chilling is required to resume vigorous growth (Guttridge, 1958). Furthermore, lengthening of the chilling period hastens inflorescence emergence (Tehranifar et al, 1998). On the other hand, a long chilling period may enhance vegetative growth at the expense of flowering (Voth and Bringhurst, 1970;Lieten et al, 1995;Lieten, 1997).…”

“…Most research so far has been conducted on 'Elsanta' and several aspects of growth and yield have been studied in this cultivar (Daugaard, 1999;Le Mière et al, 1996, 1998Tehranifar et al, 1998). There have, however, been few studies undertaken using everbearing cultivars and none to determine their light use and dry matter partitioning patterns.…”

The differences in growth and yield in the Junebearing strawberry (Fragaria ×ananassa Duch.) `Elsanta' and the everbearing `Bolero' and `Everest' were evaluated under field conditions. The seasonal patterns of radiation use efficiency and assimilate partitioning were also studied. Growth, development and yield showed considerable differences among cultivars. `Elsanta' showed the highest and `Bolero' and `Everest' the lowest values for almost all the vegetative parameters (leaf area, leaf dry weight, runner number). `Elsanta' produced large leaves and few crowns per plant in contrast to the everbearing cultivars which had more but smaller leaves and a larger number of crowns per plant. The production of flowers by `Elsanta' was concentrated in June with fruit production following in July. `Bolero' and `Everest' produced more than one flush of flowers during the season and fruited until October. As a result, yields of `Bolero' and `Everest' were greater than `Elsanta'. The higher yields of `Bolero' and `Everest' also reflected the greater number of crowns produced by these cultivars. The maximum intercepted and absorbed photosynthetically active radiation (PAR) occurred between July and August when the three cultivars showed the greatest increase in vegetative growth. Harvest index clearly differed among cultivars and this was related to the duration of cropping. The greatest harvest indexes were found for `Bolero' and `Everest'.
