INTRODUCTION Pea (Pisum sativum L.) is a commonly grown leguminous vegetable in the world. Flowering time: July–August. Example: Mustard, China rose, Brinjal. A carpel without a functional ovary is sterile. In case of pea, out of ten, nine stamens form a staminal tube while one is free. The pea inflorescence is typical of many legumes and is distinguished from the simple Arabidopsis inflorescence by an additional level of branching, with a so-called secondary inflorescence (I 2) that displaces flowers from the main inflorescence stem (Figure 1). Expression of these genes in their correct domains is maintained by a network of mutual repressive interactions. Asymmetric: When a flower cannot be divided into two equal halves from any plane, it is called asymmetric flower, e.g. maple, milkweed, dandelion, ash. An inflorescence that arises from the axil of a leaf (leaf base), as apposed to a terminal inflorescence that arises from the end of a stem.

When the flower appear to arise from a single point, the inflorescence is capitulum umbel corymb raceme 2. Diadelphous: When the filaments of anthers in a flower are fused into two groups, then the condition is called diadelphous. Based on the arrangement on floral axis, there are two main types of inflorescence: 1: Racemose inflorescence: The main axis continues to growth. Flowers are borne laterally in acropetal order.

[citation needed], Dried peas are often made into a soup or simply eaten on their own. Q14) Axile placentation is present in (CBSE AIPMT 2015) Dianthus Lemon Pea Argemone . The arrangement of flowers on floral axis is called inflorescence. The pea inflorescence is typical of many legumes and is distinguished from the simple Arabidopsis inflorescence by an additional level of branching, with a so-called secondary inflorescence (I 2) that displaces flowers from the main inflorescence stem . We can find this type of inflorescence in Labiatae/Lamiaceae family, where the leaves are arranged in opposite manner on the stem. In a raceme a flower develops at the upper angle (axil) between the stem and branch of each leaf along a long, unbranched axis. The ovary is found in the side walls of the pelvis. When a flower arises singly it is called a solitary flower. The filament is a long stalk which is capped by a sac-like structure called anther. To understand this, we have undertaken a study of the genes controlling these processes in pea. Wild-Type Pea Inflorescence Structure. They are edible when tender. Polyadelphous: When the filaments of anthers in a flower are fused into more than two groups,therefore the condition is called polyadelphous. In this type of inflorescence florets may be unisexual, bisexual and sterile. There are two major types of inflorescence, viz. Answer- Lemon .
