Abstract

Both L i26400 photosynthesis system and OS12FL chlorophyll fluorometer were used to measure thephotosynthesis characteristic and chlorophyll fluorescence parameters of Cerasus hum ilis p lant under soil waterstress. The result showed: (1) The average photosynthesis rate reached the maximum under the low water stress ,while that under the high soil water stress was the least. The stomatal conductance increased as a result of theincreasing of PAR ( Photosynthetically Active Radiation) under no soil water stress conditions and didn’t variateunder the mediums and high soil water stress conditions. Diurnal variation of photosynthesis rate p resented a two2peaks curve and showed obvious noon dep ression. The variation of net photosynthesis rates under different waterstress conditions are follows: 8. 447 ±0. 831, 6. 811 ±0. 690, 2. 658 ±0. 756, 1. 474 ±0. 469 μmol·m- 2 ·s- 1.Significant variations of Pn happened between the conditions of the former two and the later two,Diurnal variations ofCond, Tr, WUE under different soil water stress conditions were similar to the variations of Pn. ( 2 ) Thefluorescence parameter of Fo, NPQ increased with the increasing ofwater stress,while the Fv/Fm, Fv/Fo dereased.Itmeans that with the increasing of the water stress, the reaction center of PSIIwas destroyed or a non2reversibledeactivation occurred so that the photosynthesis was restrained. The photosynthetic apparatus of C. hum ilis wasp rotected by exhausting the extra light energy through heat dissipation. ( 3) WUE reached its maximum ( 1. 214 ±0. 112μmol·mmol-1 ) and the physiological parameters of photosynthesiswere op timized under low soilwater stresswith water contents from 21% - 24%.
- soil water stress,
- drought stress,
- photosynthesis rate,
- chlorophyll fluorescence,
- water use efficiency
