Berry-cup system to study phloem unloading
This simple but effective system consists of an in vivo peeled grape berry immersed in buffer in a 10 ml polypropylene cup. Wang et al. (pp. 523-528) use this system to study phloem unloading of grape sugar under different conditions. Water stress and treatment with biochemical inhibitors are shown to reduce phloem sugar unloading in grapes.
