摘    要:本文测定了不同地点的长白落叶松种源的光合、水分生理生态参数。结果表明,各种源的总光合速率〉最大净光合速率〉净光合速率〉半饱和光强时的净光合速率〉光呼吸速率〉呼吸速率,只偶有例外。各参数在种源间的变化趋势均与净光合速率一致,总光合速率变异最大,光呼吸速率、光补偿点、饱和点和半饱和点的变异较大,呼吸速率、净光合速率占总光合速率的百分比、呼吸功效、CO2补偿点、蒸腾速率和水势变异不大。水分利用率在各种源

关 键 词:长白落叶松 种源 生理 生态 造林树种 落叶松

Abstract:In this paper, physiological ecology parameters of Laix olgensis Henry from different provenances were measured. The result showed that: among all provenances, total photosynthesis rate>maximal net photosynthesis rate>net photosynthesis rate>net photosynthesis rate at semi-light saturation>light respiration rate>respiration rate, but there is individual exception. Change tendency of each parameter among the provenances is in accordance with net photosynthesis rate. Total photosynthesis rate varied most; light respiration rate, light compensation point, light saturation point and semi-light saturation point varied greatly; respiration rate, percentage of net photosynthesis rate to total photosynthesis rate, respiration efficiency, CO 2 compensation point, transpiration rate and water potential varied less. The more variation of efficiency of water utilization resulted from net photosynthesis rate.
Keywords:Larix olgensis Henry  Provenance  Physiological ecology
