The Rachis Revealed


During this rapid shoot development phase, take a closer look at the cluster's branch system, known as the “rachis,” extending from the lower portion of the new shoots.


At first, it may seem like little baby grapes are forming at the tips (like tiny corn), but these are actually flower parts protected by five shell-like petals, fused into a structure called the calyptra. Inside, you'll find five developing stamens (male parts) surrounding the pistil (female part), with the process uncannily mirroring human behavior! As the pollen and eggs mature, the petals of the calyptra will release and fall off, revealing nature’s intricate design.
