摘要:
利用英国PP-SYSTEM公司生产的TPS-1便携式光合作用测定系统，对3个树莓品种的光合特性进行了比较研究，结果表明树莓叶片光合速率日变化呈双峰曲线，A品种 “日中低落”现象明显，B、C品种不甚明显；B、C品种的蒸腾速率日变化曲线基本上为双峰型,日变化过程中的“午休”现象非常明显，而A品种为单峰型，日变化过程中的“午休”现象不甚明显；此外，叶片气孔导度与叶片光合速率的日变化趋势基本一致，呈平行变化趋势，说明气孔导度是影响光合速率的直接因子；较B、C品种而言，A品种具有较高的水分利用效率，说明其更能节约并有效地利用土壤水分。
Abstract:
A portable photosynthesis system made by PPSYSTEM Ltd. was used to study the photosynthetic properties of 3 cultivars（A、B and C）of Rubus idaeus under the field conditions. The results indicated that the individual leave net photosynthetic rates had 2 peaks during a day，an obvious photosynthetic midday slump was observed in A，there was a significant difference in midday depression among the 3 cultivars；evaporation rates of B and C had 2 peaks during a day，while A had 1 peak，and an obvious midday slump was observed in B and C；Stomatic conductance is the key factor of midday slump；Compared with B and C，A had a higher water using efficiency，which will consume less soil water.
