- 摘要:
- 以大连地区引种栽培的4个南高丛越橘品种为研究对象，利用LI-6400XT光合作用测量仪，研究了净光合速率对25～36℃间各温度区间的光合-温度响应曲线，以及净光合速率对1 200、1 000、800、600、400、200、100、50、30、10、0 μmol·m-2·s-1各光合有效辐射的光合-光响应曲线的变化规律。结果表明：高温环境下光合生理活动表现较好的是“海岸”、“比格克西”，其次是“库帕”，再次是“蓝铃”；利用光强能力最强的是“海岸”，其次是“比格克西”，再次是“蓝铃”、“库帕”；耗水量大的品种是“海岸”，“库帕”和“比格克西”适中，耗水量小的品种是“蓝铃”；该研究结论旨在为其它地区引进栽培南高丛越橘提供理论参考。
- Abstract:
- Taking four southern highbush blueberry species in Dalian,northeast China as materials,using LI-6400XT portable photosynthesis system,the net photosynthetic rate-temperature curves from 25～36℃ and the net photosynthetic rate-light intensity curves including 1 200,1 000,800,600,400,200,100,50,30,10,and 0 μmol·m-2·s-1?were measured.The results showed that the net photosynthesis rate of ‘Gulfcoast’ was the highest one and that of ‘Bluebell’ was the lowest one among all the measured species under high temperature conditions.In terms of light response ability,the ‘Gulfcoast’ was the highest one and the order from high to low was ‘Gulfcoast’>‘Biloxi’>‘Bluebell’>‘Cooper’.Moreover,‘Gulfcoast’ species had the highest transpiration rates and the other three species (‘Cooper’,‘Biloxi’ and ‘Bluebell’) had lower transpiration rates under warmer conditions.The aim of this study was important significance for introducing southern highbush blueberry species to other regions of China.
