Abstract

The measurements of diurnal pattern of net photosynthetic rate of Acacia mangium , A .aulacocarpa , A .auriformis , A .holosericea , A .cunninghamii , Eucalyptus camaldulensis , E .exserta ,E .citriodora were carried out in three year old stands in Zulin twonship , Yuanmou County .The net photosynthesis rate in eight species showed the double-peak pattern during the drought period .The maximum of photosynthetic rate appeared at 9 :00 and 15 :00 respectively (A .aulacocarpa , A .auriformis and A .cunninghamii at 17 :00).The minimum appeared at 13 :00 (A .cunninghamii at 15 :00).The photosynthesis patterns in eight species showed significant midday depression caused by the closure of stomata .This midday depression must be one of the adaptation of the plant to the climate of dry-hot valley , regulating the moisture condition in the stand and saving the water for survival .
