摘要/Abstract

摘要： 研究了4个高灌蓝莓品种( ‘泽西’、‘日出’、‘乔治亚吉姆’和‘里维尔’) 的光合作用启动
过程, 及其光合作用对环境因子的响应。结果表明: 4个品种的光合启动时间均较长(46～75 min) , 其中
‘里维尔’的光合启动最快, ‘日出’最慢。这4种蓝莓的CO₂补偿点均较高(89～121 μmol·mol^-1 ) , 是典
型的C3 植物。相对南高灌蓝莓品种, 北高灌品种‘日出’和‘泽西’具有较高的光合能力、羧化效率、PSⅡ
最大光化学效率和饱和光强, ‘日出’的光补偿点最低(18.22 μmol·m^-2·s^-1 ) , 具备耐阴生树种的特征。
北高灌品种的光合最适温度较低, 范围也较窄(23～25℃) , 不适宜在南方高温地区种植; 相比之下, 南高
灌品种‘里维尔’具有较高和较宽的光合最适温范围(23～35℃) , 适宜引种的区域范围较宽。

Abstract: The photosynthetic induction and response of photosynthesis to environmental factors were
investigated in 4 high-bush blueberry cultivars. The results showed that the time of photosynthetic induction
was quite long ( 46 - 75 min) , the photosynthetic induction was the fastest in Reveille, whereas it was the
slowest in Sunrise. The CO₂ compensation points were rather high ( 89 - 121 μmol ·mol^-1 ) in the 4
cultivars, indicating that all of the 4 cultivars are typ ical C3 p lants. Compared to southern high2bush blueber
ries, the northern high2bush blueberries Sunrise and Jersey had higher photosynthetic ability, carboxylation
efficiency, the maximal photochemical efficiency of PS Ⅱ and saturation light intensity. In addition, the
Sunrise had the lowest light compensation point and characteristics of shade tolerant p lant. However, the
op timum photosynthetic temperature was lower and the range of itwas narrower (23 - 25℃) , indicating that
these cultivars were not suitable to grow in southern region with high temperature. The southern high-bush
blueberries Reveille, as compared with northern high2bush blueberries, had a wider range (23 - 35℃) of op
timum photosynthetic temperature, which extended its range of introduction and cultivation.

Key words: Blueberry, Photosynthesis, Photosynthetic induction, Apparent quantum yield, Carboxylation efficiency
