| 中文摘要: |
| 以大连地区引种栽培的南高丛蓝莓6个品种为研究对象，使用LI-6400XT光合作用测量仪测量其净光合速率对25℃-36℃间各个温度的光合-温度响应曲线，以及净光合速率对1200、1000、800、 600、400、200、100、50、30、10、0（μmol/（m2?s））各光合有效辐射下的光合-光响应曲线。经过曲线分析表明，高温环境下光合生理活动表现较好的是蓝雨，其次是开普菲尔，奥尼尔、夏普兰、蓝脊3个品种适中，表现最差的是薄雾；利用光强能力最强的是蓝雨和开普菲尔，其次是蓝脊，再次是夏普兰和奥尼尔，利用光强能力最差的是薄雾；耗水量大的品种是开普菲尔和夏普蓝，蓝脊适中，耗水量小的品种是蓝雨、薄雾和奥尼尔。研究结论旨在为其他地区引进栽培南高丛蓝莓提供理论参考。 |
| 英文摘要: |
| In this study, we examined the photosynthetic characteristics of six southern highbush blueberry species in Dalian, northeast China. We measured the net photosynthetic rate-temperature curves from 25℃-36℃and the net photosynthetic rate-light intensity curves including 1200, 1000, 800, 600, 400, 200, 100, 50, 30, 10, and 0 (μmol m-2?s-1) with an LI-6400XT portable photosynthesis system. We found that the net photosynthesis rate of Bluerain is the highest one and that of Misty is the lowest one among all the measured species under high temperature conditions. Moreover, we also found that Cape Fear and Sharpblue have higher transpiration rates and Bluerain, Misty, and O′Neal have lower transpiration rates under warmer conditions. This study may have important significance for introducing southern highbush blueberry species to other regions of China. |
