can you give me the specific vegetative development of the plant?

Question

specific vegetative development
such as juvenile stage of the plant

Answer 1

The growth of the grass plant is divided into three phases:
1. vegetative (germination to panicle initiation);
2. reproductive (panicle initiation to flowering); and
3. ripening (flowering to mature seed)
These 3 growth phases consist of a series of 10 distinct stages. These stages are numbered and described as Stage 0 thru 9.
Stage 0 is from germination to emergence:
Stage 1 is called seedling:
Stage 2, tillering:
and Stage 3 is stem elongation:
These first 4 stages make up the vegetative phase, the first phase of grass plant growth.
Stage 4 is panicle initiation to booting:
Stage 5 is heading or panicle exsertion:
and Stage 6 is flowering:
Stages 4, 5, and 6 constitute the reproductive phase, the second phase of plant growth.
Stage 7 is the milk seed stage:
Stage 8, the dough seed stage:
and Stage 9, the mature seed stage:
Stages 7 through 9 correspond to the ripening phase, the last phase in the development of the grass plant.
