Which sequence correctly describes the reproductive growth stages of corn from R2 to R5?

The sequence that accurately represents the reproductive growth stages of corn from R2 to R5 is Blister, Milk, Dough, and Dent.

At the R2 stage, known as the Blister stage, kernels begin to form within the husk and take on a blister-like appearance due to the swelling of the kernel. This is followed by the R3 stage, called the Milk stage, where the kernels fill with a milky fluid and are still quite soft. Next is the R4 stage, referred to as the Dough stage, where kernels continue to develop and the contents thicken, resembling dough. Finally, at the R5 stage, known as the Dent stage, kernels begin to harden and a characteristic dent forms on the top as they reach physiological maturity.

This sequence is crucial for understanding the corn development process, particularly for farmers and agronomists who need to monitor these stages for optimal harvest timing and management practices. Each stage has unique characteristics that indicate the progression of kernel development and overall crop maturity.
