马尾松是我国南方生态恢复与重建的先锋树种,具有耐干旱、耐贫瘠及速生丰产等优点,其人工林在我国森林资源总量中占举足轻重的位置,但纯林的养分循环差,易导致生产力低下;而研究马尾松光合生理特性及资源利用效率可以为马尾松人工林生产力的提高提供坚实的理论基础。文中综述马尾松光合生理特性及资源利用效率的研究进展,分析逆境胁迫对其光合生理特性及资源利用效率的影响,包括水分胁迫、热胁迫、酸雨胁迫、低磷胁迫及铝胁迫等。在全球变化背景下,研究马尾松光合生理特性与资源利用效率及其对逆境胁迫的响应,对于制定马尾松的管理与保护策略、挖掘其抗性潜力具有重要意义,可为马尾松林分生产力的提升及纯林改良策略的制定提供理论参考。
Pinus massoniana is the pioneer tree species for ecological restoration and reconstruction in southern China, which has the advantages of drought tolerance, poor resistance and fast-growing and high yield. Its plantation occupies a pivotal position in the total forest resources of our country, however, Poor productivity; and study of photosynthetic physiological characteristics of Pinus massoniana and resource efficiency can provide a solid theoretical basis for improving the productivity of Pinus massoniana plantation. The paper reviewed the research progress of photosynthetic physiological characteristics and resource utilization efficiency of Masson pine and analyzed the effects of stress stress on its photosynthetic characteristics and resource utilization efficiency, including water stress, heat stress, acid rain stress, phosphorus deficiency stress and aluminum stress. Under the background of global change, studying the photosynthetic physiological characteristics and resource utilization efficiency of Masson pine and its response to adversity stress is of great significance for formulating management and protection strategies of Pinus massoniana and mining its resistance potential, Improve and improve the strategy of pure forest to provide a theoretical reference.
