“…There was a strong negative relationship between average fruit weight and the average daily mean temperature during fruit development (four weeks before harvest) or during flower and fruit development (seven weeks before harvest). Menzel [36] indicated that average fruit fresh weight decreased as the average mean daily temperature increased from 16 • C to 20 • C in Queensland.…”

“…Strawberry fruit are produced from inflorescences called cymes, with a hierarchy of fruit decreasing in size with inferior positions of the flowers [36]. A primary flower is initiated at the end of the cyme, with secondary, tertiary, and possibly quaternary and quinary flowers initiated from the axes below the preceding blooms.…”

“…MacKenzie et al [35] indicated that there was a strong negative relationship between soluble solids content (SSC) and mean temperature in the eight days before harvest in Florida (R 2 = 0.73). Menzel [36] demonstrated that average fruit fresh weight decreased by more than 50% as the temperature increased from 16 • C to 20 • C in Queensland.…”

Five strawberry (Fragaria × ananassa Duch.) cultivars were grown in Queensland, Australia to determine whether higher temperatures affect production. Transplants were planted on 29 April and data collected on growth, marketable yield, fruit weight and the incidence of small fruit less than 12 g until 28 October. Additional data were collected on fruit soluble solids content (SSC) and titratable acidity (TA) from 16 September to 28 October. Minimum temperatures were 2 °C to 4 °C higher than the long-term averages from 1965 to 1990. Changes in marketable yield followed a dose-logistic pattern (p < 0.001, R2s = 0.99). There was a strong negative relationship between fruit weight (marketable) and the average daily mean temperature in the four or seven weeks before harvest from 29 July to 28 October (p < 0.001, R2s = 0.90). There were no significant relationships between SSC and TA, and temperatures in the eight days before harvest from 16 September to 28 October (p > 0.05). The plants continued to produce a marketable crop towards the end of the season, but the fruit were small and more expensive to harvest. Higher temperatures in the future are likely to affect the economics of strawberry production in subtropical locations.

Impact of Temperatures During Fruit Development on Fruit Growth Rate and Qualities of ‘KU-PP2’ Peach

et al. 2022

In protected agriculture, optimum temperature management is crucial for enhancing fruit productivity and maintaining cost-effective production. The aim of the present study was to investigate the effects of temperature on peach fruit development and quality. Container-grown 'KU-PP2' peach trees grafted on low-chill peach rootstocks were cultivated under controlled conditions at different temperatures (20, 25, and 30°C) during fruit development for two years (2020 and 2021). Fruit growth rates were calculated by measuring fruit diameter every 3 d from fruit setting to first harvest; fruit quality and phytochemistry were analyzed at harvest. Growing temperature markedly affected fruit growth, maturation, and fruit quality. The development of fruit in all treatments exhibited double sigmoid growth curves that included three stages (S1, S2, and S3). Fruit growth rate during S1 and S2 stages was increased, and fruit development period was significantly shortened with an increase in temperature. Contrary to the duration of S3, which was longer at higher temperatures, fruit grown at a high temperature (30°C) ripened by 12-18 days earlier than those grown at low-temperature regimes. In addition, high-temperature conditions were also associated with reduced fruit quality (size, weight, and sweetness), but enhanced development of red coloration. Therefore, even though high-temperature conditions can accelerate early fruit expansion and hasten fruit maturity, such conditions also have negative effects on important agronomic fruit traits.

“…Woodland strawberry ( Fragaria vesca L.) is a perennial rosette plant and a model for the octoploid cultivated strawberry ( Fragaria × ananassa ) and the Rosaceae family in general (Edger et al 2018). Historically, inflorescence architecture of Fragaria has been classified as pleiochasial cyme (Valleau, 1918), dichasial cyme (Anderson & Guttridge 1982; Guttridge, 1985), cyme (Menzel, 2019) and corymb (Gleason & Cronquist, 1991). This diversity of terms reflects the extensive morphological variability of strawberry inflorescences, which was highlighted almost a century ago (Darrow, 1929).…”

A vast variety of inflorescence architectures have formed during angiosperm evolution. Here we analyze the diversity and development of the woodland strawberry inflorescence. We show that it is a thyrse: a compound inflorescence in which the primary monopodial axis supports lateral sympodial branches, thus combining features of racemes and cymes. We demonstrate that this architecture is related to differences in the size and shape of the primary and lateral inflorescence meristems. We further show that woodland strawberry homologs of TERMINAL FLOWER 1 (TFL1) and FLOWERING LOCUS T (FT) antagonistically regulate the development of both the racemose and cymose components of the strawberry thyrse: the loss of functional FvTFL1 and overexpression of FvFT1 reduce the number and complexity of the cymose components, whereas silencing of FvFT1 has the opposite effect and can partially rescue the fvtfl1 mutation. We complement our experimental findings with a computational model, which captures the development of the woodland strawberry inflorescence using a small set of rules, and shows that its phenotypic diversity can be explained in terms of heterochrony resulting from the opposite action of FvTFL1 and FvFT1 on the progression from the branching to flowering state.
