Racemose Inflorescence
Racemose inflorescence is a type of inflorescence in which the main axis continues to grow indefinitely and bears a number of flowers due to the active growing point. The flowers are arranged along the axis in an acropetal manner, i.e., the oldest flower is present at the base, and the youngest flower is present at the top.
Types of Racemose Inflorescence
There are three types of racemose inflorescence:
1. Simple Raceme: It is a type of racemose inflorescence in which the pedicellate flowers are arranged along the main axis in a single row, e.g., mustard.
2. Compound Raceme: It is a type of racemose inflorescence in which the main axis bears secondary rachis, and the pedicellate flowers are arranged along the secondary rachis in a single row, e.g., laburnum.
3. Spike: It is a type of racemose inflorescence in which the pedicellate flowers are sessile and arranged along the main axis, e.g., wheat.
Examples of Racemose Inflorescence
- Mustard
- Pea
- Radish
- Cabbage
- Laburnum
- Wheat
- Sorghum
Characteristics of Racemose Inflorescence
- The main axis of racemose inflorescence is indefinite and continues to grow.
- The flowers are arranged in an acropetal manner.
- The oldest flower is present at the base, and the youngest flower is present at the top.
- The flowers are pedicellate or sessile.
- The flowers are arranged along the main axis or its branches.
- The growing point of the inflorescence is active.
