A Tentative Method for Monitoring the Dynamic Features of Transpiration Regulation in Ferula krylovii Leaves
摘要
Abstract
The transpirational dynamics and regulation features in leaves of Ferula krylovii grown in a desert area of Xinjiang, China were monitored, recorded and analysed systematically with a high-sensitivity humidity sensor combined with a specific leaf chamber and other types of sensors. The results were compared with those from other methods such as photosynthetic meters or weighing. Parameters associated with fast regulation (within 1-2 min) and diurnal variations in transpiration rate were clearly monitored and recorded. The parameters obtained could be used to analyse the correlations between transpiration and the effect of changes in environmental factors such as temperature, light intensity, and humidity to uncover more details on the transpirational dynamics and regulation features of a plant, details that other methods are unable to provide. Because larger samples could be measured with this method, the disadvantages of other methods could be excluded, such as errors due to the selection of the local sampling site, systematic errors due to smaller gas samples, and possible mechanical stress due to the clamp of the leaf chamber. This method, combined with other types of sensors, could yield parameters that cover more extensively the transpirational water consumption and regulation of plants under varied environmental conditions and provide a more detailed dynamic perspective of plants in their adaptation to environments, with the possibility of remote, continuous monitoring.关键词
