All the above showed that the light energy conversion efficiency , potential activity of photosynthetic reaction center and the non-photochemical dissipation of excess light energy , which resisted the damage on photosynthetic apparatus of environmental stress , were improved .
表明外源NO处理一方面提高了光能转换效率和PSⅡ的潜在活性,另一方面增强了过剩光能的非化学耗散,有利于保护光合机构免受环境胁迫的伤害。

Oxygen-evolving photosynthetic organisms contain two types of photosynthetic reaction center , called photosystem ⅰ( PS ⅰ) and photosystem ⅱ ( PS ⅱ) . The PS ⅱ reaction center uses water as a source of electrons , light energy being used to oxidize water to provide protons and oxygen .
光合放氧生物包括光系统Ⅰ(PSⅠ)和光系统Ⅱ(PSⅡ)两种类型反应中心,光系统Ⅱ反应中心能以水作为电子给体,利用光能氧化水产生质子和氧气。

When plants absorb more light than that can be used for photosynthesis , the excess energy , which is not promptly quenched , can reduce the photosynthetic efficiency and result in photoinhibition , even photooxidative damage to the photosynthetic reaction center .
然而,大多数情况下植物接受的能量要超过其所能转化的能量,如果过量的光能不及时耗散掉,光合功能会降低,导致光合作用的光抑制,甚至出现光氧化、光破坏。
