缺锰损害植物光合作用的机理尚不完全清楚。研究了缺锰对玉米光合磷酸化和CO2同化关键酶活性的影响。在Hoagland溶液中栽培玉米植物。他们受到锰缺乏症和锰管理的锰缺乏Hoagland的媒体。结果表明，缺锰导致玉米株重、叶绿素a含量、电子传递和放氧速率、光合磷酸化速率、Mg 2 +-ATPase、Ca 2 +-ATPase、Rubisco和Rubisco活化酶活性以及Rubisco和Rubisco活化酶mRNA表达量显著下降，但对叶绿素B和类胡萝卜素的形成影响较小。但施锰可缓解缺锰对玉米光合作用的抑制。
The mechanism of the fact that Mn deficiency damages the photosynthesis of plants is not yet fully understood. The main aim of the study was to determine Mn deficiency effects in photophosphorylation and key enzymes of CO2 assimilation of maize. Maize plants were cultivated in Hoagland's solution. They were subjected to Mn deficiency and to Mn administered in the Mn-deficient Hoagland's media. The results showed that Mn deficiency was found to cause extensive declines in plant weight and chlorophyll a content, electron transport and oxygen-evolving rate, photophosphorylation rate, activities of Mg2+-ATPase, Ca2+-ATPase, Rubisco and Rubisco activase, and mRNA expressions of Rubisco and Rubisco activase of maize, but it only slightly affected chlorophyll b and carotenoid formation. However, Mn addition decreased the inhibition of the photosynthesis in maize caused by Mn deficiency.
