Abstract
We studied the functional advantages of persistent calyx and labiate corolla in Brandisia hancei, a typical winter-flowering shrub. The calyx and corolla function as a tiny greenhouse, and thus the floral temperature can be up to 10℃ higher than the ambient temperature. However, temperature excess disappeared after shading. The manipulation on perianth generally resulted in lower floral temperatures and lower seed production, while both temperature and seed production regained after repairing the corolla.
This dataset includes 11 files, files 1-9 are about temperature, and files 10-11 are about seed production.
File 1 describes daily dynamics of floral temperatures on a rainy day, 17th December 2023. One flower at the Opening stage and another adjacent flower at the Opened stage were selected to measure the floral temperatures, and the nearby ambient temperature simultaneously at 6-min intervals for 24 hours.
File 2 is about daily temperature dynamics at an interval of 6 minutes, on a cloudy day, 31st January 2024. The floral temperatures of two flowers at stages of Opening and Opened, and the nearby ambient temperature were simultaneously measured.
File 3 describes floral and ambient temperatures under sunny and shaded conditions. For each condition, floral and nearby ambient temperatures for an opened flowers were measured simultaneously at 1-min intervals for 30 min (15:31-16:00) on 27th December 2023.
File 4 is for floral temperatures of an intact flower the stage of Opening and a calyx-removed flower at the same stage, and the ambient temperature. Temperature measurements were conducted using eighteen replicates, and for each replicate, the temperature was measured at 1-min intervals for 10 min on 1st February 2024, and on 27th and 28th February 2025.
File 5 is for floral temperatures of an intact flower the stage of Opened and a calyx-removed flower at the same stage, and the ambient temperature. Temperature measurements were conducted using eighteen replicates, and for each replicate, the temperature was measured at 1-min intervals for 10 min on 1st February 2024, and on 27th and 28th February 2025.
File 6 is for floral temperatures of an intact flower after corolla naturally fell off (the stage of Fallen) and a calyx-removed (partly) flower at the same stage, and the ambient temperature. Temperature measurements were conducted using eighteen replicates, and for each replicate, the temperature was measured at 1-min intervals for 10 min on 31st January, and on 27th and 28th February 2025.
File 7 is for floral temperatures of an intact flower the stage of Opening and a corolla-removed flower at the same stage, and the ambient temperature. Temperature measurements were conducted using eighteen replicates, and for each replicate, the temperature was measured at 1-min intervals for 10 min on 1st February 2024, and on 27th and 28th February 2025.
File 8 is for floral temperatures of an intact flower the stage of Opened and a corolla-removed flower at the same stage, and the ambient temperature. Temperature measurements were conducted using eighteen replicates, and for each replicate, the temperature was measured at 1-min intervals for 10 min on 1st February 2024, and on 27th and 28th February 2025.
File 9 is for floral temperatures of flower at the stage of Opening: intact control, after making a hole in the corolla and sealing the hole with Vaseline. Temperature measurements were conducted using eighteen replicates, and for each replicate, the temperature was measured at 1-min intervals for 10 min on 31st January and 1st February 2024, and on 27th and 28th February 2025.
File 10 is for seed production (seed number per fruit) in two years, after three treatments: intact control, calyx removal and corolla removal.
File 11 is for seed production (seed number per fruit) in two years, after three treatments: intact control, making a hole and sealing the hole with Vaseline.
All temperatures were measured with multichannel thermocouple thermometers. When floral temperature was measured, the probe was inserted into the bottom of the flower. The probe for measuring ambient temperature was placed behind an adjacent leaf to avoid rain or sunlight. Fruits were collected at the beginning of April, after which the seeds were counted.
