Abstract

Diurnal variations of leaf－air interface physiological parameters in leaves of three－year－old Am ygdalusdavidiana were studied under different soilmoisture conditions with C IRAS－2 portable photosynthesis system in theloess hilly p lateau. The results indicated that the diurnal variation p rocess of photosynthesis, transp iration and wateruse efficiency under different soilmoisture conditions took on different regulations. When soil relative water contentwas 57. 3% , 70. 1% , 80. 2% , the time that maximum disp lay was at 13: 00, 9: 00 and 15: 00, respectively, and the maximum values of photosynthetic rate were 10. 51, 12. 52, 9. 25 μmol·m-2·s-1 , respectively, the dailyaverage valueswere 6. 83 ±4. 92, 6. 40 ±4. 43 and 6. 32 ±3. 90 μmol·m-2·s-1 , respectively. In other soilmoisture conditions, all the photosynthetic rate followed a two－peak pattern; The style of diurnal variation curves oftransp iration rate was similar with that of photosynthetic rate, when soil relative water contents were 57. 3% ,70. 1% , 80.2% , the time thatmaximum disp laywas always at 13: 00, and the daily average values of transp irationrate were 1.91 ±1. 03, 3. 27 ±2. 09, 2. 90 ±1. 70μmol·mol- 1 , respectively; The maximum ofwater use efficiencybefore 13: 00 appeared at 7: 00 or 9: 00, but itwas very distinct after 13: 00. Analysis showed the dominating reasoncausing the photosynthetic rate fallwas stoma limitation when relative water contentwas over 57. 3%. In other soilmoisture conditions, stoma limitation was the dominating reason before 13: 00, while non2stoma limitation becamedominant after 13: 00. According to the connections between the photosynthetic rate, transp iration rate , water useefficiency and soil moisture, in loess hilly p lateau, the fitting soil relative water content maintaining Am ygdalusdavidiana natural growth was between 39. 7% and 57. 3%. At the same time, it should be p lanted in shady slope orsemi2shady slope in site design.
