Figure Lengend Snippet: Steps involved in the LT 50 freezing test. Seeds were nucleated with shaved ice at -2 °C and the temperature was subsequently lowered at the rate of 2 °C for one hour. Samples were removed at various temperatures, thawed overnight at 2 °C, and then placed into a germination chamber at 23 °C in the dark.

Article Snippet: Thawed seeds were then germinated in Petri dishes lined with hydrated triple Whatman #1 filter paper, without free-standing water, at a constant temperature of +23 °C in darkness in the germination chamber (Powers Scientific, Inc., DS33SD, Ontario) ( ).

Figure Lengend Snippet: An overview of the schematic workflow of non-contact VCs exposure on rice seedlings experimental design and conditions. ( 1 ) Rice seeds were sterilized with 1% sodium hypochlorite. After 4 days of germination, rice seedlings were transplanted into a plant box with culture soil. Seedlings are exposed to mushroom fungi bed-derived VCs (+VCs) in a non-contact setup, while control seedlings remain unexposed (−VCs). Growth conditions include a 13 h light/11 h dark photoperiod, 123 ± 6 μmol m⁻ 2 s⁻ 1 and 122 ± 9 μmol m⁻ 2 s⁻ 1 PPFD, and around 60% relative humidity for 14 days. ( 2 ) HS-SPME-GC-TOF-MS analysis identified 3-octanone, 1-octen-3-ol, 1-octen-3-one, and 3-octanol as key fungal VCs present in shiitake mushroom FBs.
