Due to the economic importance of strawberries, many countries have established national breeding projects to extend the flowering time and fruiting season to provide year-round fruit availability. Although dark septate endophytic (DSE) fungi have been reported to promote growth, the symbiotic association that alters flowering behaviors in photoperiodic crops remains unknown. The present study aims to determine the potential functions of Cladophialophora chaetospira SK51 to induce strawberry flowering grown under non-flower-inductive conditions. We established an experimental scheme for inducing the short-day (SD) strawberry genotype Fragaria vesca to initiate flowering under a long-day (LD) photoperiod in symbiotic association with DSE fungus. The experiments were conducted between March 2021 to April 2022 at Ibaraki University, Japan. Using Pearson's correlation analysis, we examined the relationship between growth-promoting and flowering-inducing traits. The symbiotic performance of C. chaetospira SK51 significantly stimulated the SD strawberry genotype to initiate early flowering, with the greatest flower induction (94.8%) and highest number of fruits (10.63 fruits/plant) during cultivation under a 16-h LD photoperiod at 23 °C, defined as non-flower-inductive conditions. We discovered that interactions between SK51 and strawberry plants significantly accelerated flowering time, with flower buds forming 90 days earlier than in untreated control plants. Strawberry plants in symbiosis with SK51 may be well-adapted to all regions and contribute to the crop's resilience against adverse climate conditions. These findings are critical for photoperiodic flowering research and innovation that can be adapted to increase crop production. [ABSTRACT FROM AUTHOR] |
