Abstract
In this study the effect of increasing temperature on photochemical efficiency of PS II in wheat plants has been studied on a hot summer day (9:00 AM (Control)-7:00 PM) by measuring Chl a fluorescence. Increasing temperature for a short period of time (2-4 h), in nature affects the efficiency of PS II complex reversibly and does not cause permanent damage to any of the components of photosystem II. A scheme has been provided to demonstrate the sequence and severity of events which get affected maximum by temperature stress.
摘要
本研究通过叶绿素荧光测量，研究了在一个炎热的夏日（9:00 AM（对照）-7:00 PM）中，温度升高对小麦植株 PS II 光化学效率的影响。在自然界中，短时间（2-4 小时）升高温度会可逆地影响 PS II 复合物的效率，不会对光系统 II 的任何组件造成永久性损伤。本文提供了一个方案，以展示受温度胁迫影响最大的事件的顺序和严重程度。
