For vine and cutting, ten flowers from five different inflorescences were analysed to study the presence of starch, and each inflorescence was sampled from a different vine or cutting. For each stage of development, the ten flowers considered show similar results for starch content. Structures are scored a ‘+’ if the ten inflorescences had starch, and a ‘0’ if the ten inflorescences had no starch.
