The ringing experiment, where bark and phloem are removed, causes swelling above the removed ring due to accumulated sugars and kills tissue below, demonstrating that the phloem is responsible for sucrose translocation.
- bark and phloem layers removed from tree - tissue above ring swells - high sucrose concentration - because phloem sugars accumulate above removed ring - tissue above ring continues to grow - tissue below ring dies - Therefore the phloem is responsible for sucrose translocation
