Photosynthetic Activity in Highbush Blueberry Plants: A Review

This comprehensive review examined leaf photosynthetic rates, research methodologies, and existing knowledge gaps in highbush blueberry ( Vaccinium corymbosum interspecific hybrids) research through a systematic and quantitative analysis of scientific literature spanning the past six decades. Studies of photosynthesis in northern and southern highbush blueberry were reviewed, revealing a lack of consensus on environmental set points for studying blueberry photosynthesis. Research of northern highbush blueberry has been more prevalent than that of its southern counterpart. According to the literature, northern highbush blueberry exhibits higher leaf photosynthetic rates than that of southern highbush blueberry, but both blueberry types exhibit lower photosynthetic rates than those of other fruit crops. Additionally, there is no evidence that selective breeding has increased blueberry leaf photosynthetic rates. Additional research is needed to understand and optimize highbush blueberry photosynthesis in agricultural settings.
