Cotyledons on the Pima cotton plants are open and have started splitting. Plumules are beginning to develop. Below photograph shows a bulging Pima cotton stem and the first true leaves emerging.

Each plant will be tagged when it reaches this stage. The seedling up for discussion is denoted P-2-13. There are at least two ways to designating a cotton plant’s age; date planted, and the date the cotyledons are fully open. In the current case, the cotyledons opened 11 days after planting.
