Floral temperatures and seed production in Brandisia hancei

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., 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., , 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 an...,

本研究针对典型冬季开花灌木Brandisia hancei的宿存花萼（persistent calyx）与唇形花冠（labiate corolla）的功能优势展开探究。花萼与花冠可充当微型温室，使得花朵温度较环境温度最高可高出10℃。但经遮光处理后，这种温度偏高的现象便会消失。对花被（perianth）进行人工干预通常会导致花朵温度与种子产量下降，而修复花冠后，二者均可恢复至原有水平。
所有温度数据均采用多通道热电偶测温仪（multichannel thermocouple thermometers）采集。测量花朵温度时，需将测温探头插入花朵基部；环境温度测量探头则置于邻近叶片后方，以避免雨水或阳光直射干扰。实验于四月初采集果实，随后对种子进行计数统计。

本数据集共包含11个数据文件，其中文件1至9为温度相关数据，文件10至11为种子产量相关数据。
文件1记录了2023年12月17日雨天的花朵温度日动态变化。本实验选取1朵处于绽放期（Opening stage）与1朵邻近的处于盛开期（Opened stage）的花朵，以6分钟为间隔，连续24小时同步测量其花朵温度与周边环境温度。
文件2记录了2024年1月31日阴天的温度日动态变化，采样间隔为6分钟。实验同步测量了2朵分别处于绽放期与盛开期的花朵温度，以及周边环境温度。
文件3记录了晴天与遮光两种条件下的花朵温度与环境温度。2023年12月27日，针对两种条件下的单朵盛开花朵，以1分钟为间隔，连续30分钟（15:31-16:00）同步测量其花朵温度与周边环境温度。
文件4为单朵处于绽放期的完整花朵的温度数据……
