Answer- Cucumber . In the pea inflorescence apex, DET expression in the primary inflorescence meristem (I2), VEG1 in the secondary inflorescence meristem (I2) and PIM in the floral meristem (F) are required for these meristems to acquire their identity.

In this paper we present a detailed characterization of the pea MADS‐box gene PEAM4. 44. Which fruit or seed is dispersed by the wind? racemose and cymose. Pea 1. INTRODUCTION Pea (Pisum sativum L.) is a commonly grown leguminous vegetable in the world. The important producers of pea in the world are USA , China , France , U.K., Holland , Russia , Egypt and Australia. Leaves: Alternate, fairly stalkless, stipulate. E.g, bean. C. A sterile pistil is called a staminode. Diadelphous: When the filaments of anthers in a flower are fused into two groups, then the condition is called diadelphous. - Monopodial branching. Pineapple. Small flower are inconspicuous. Tomatoes, Grapes. Uses. This inflorescence is found in Euphorbiaceae family like Euphorbia, Poinsettia, Pedilanthus. (a) The androecium of pea flower is diadelphous because the filaments of anther are united in two bundles. In india pea is a extensively cultivated in Uttar Pradesh , Bihar and Madhya Pradesh. Families this large often have subgroupings called subfamilies and tribes. The important differences observed in pea flower and inflorescence development, compared to other model species, raise the question of how orthologous genes operate in such different contexts. (b) Ray florets of sunflower are neuters because both male and female reproductive organs are lacking or absent. II- Cymose inflorescence. An indeterminate inflorescence may be a raceme, panicle, spike, catkin, corymb, umbel, spadix, or head. A. PEA naturally maintains and regulates neuronal activity. 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. Such an arrangement is called basipetal succession. 2) The main axis in racemose inflorescence continues to grow and produce flowers laterally. In case of pea, out of ten, nine stamens form a staminal tube while one is free. (b) pea (c) lemon (d) mustard. There are two forms of solitary flowers. Heterozygous: 25: The main source of male sterility in sorghum? Pure line: 28: Banana inflorescence is known as? Inflorescence is surrounded by whorl of bracts collectively called involucre.

A group of flower is called inflorescence. ˈsiːm/ or /r?ˈsiːm/) is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called pedicels) along its axis. 1. Leaflets elliptic, with entire margins, quite juicy, bluish-green. Read more>> 1. ... the large posterior petal is called-standard, two lateral ones are wings and two small anterior petals are termed keel. The filament is a long stalk which is capped by a sac-like structure called anther. maple, milkweed, dandelion, ash. Flower is usually white or light pink in color and looks like a butterfly. AgriExam.Com: Spadix: 29: The process of Development fruit without fertilization is called? This process of altering the seed coat to permit germination is called. Most flowers develop scorpioid cyme inflorescence. ... to the ovary, enclosed in the carpel. The Pea family is very large, with 600 genera and 13,000 species worldwide, all descendents of the very first Pea flower of many millions of years ago. ... Zygomorhphic: When a flower shows bilateral symmetry, it is called a zygomorphic flower, e.g. Blade pinnate, 3–5-pairs, terminal leaflet modified into a tendril. A carpel without a functional ovary is sterile. In the hypogynous flower the gynoecium occupies the highest position while the other parts are situated below it. It is the characteristics aestivation of corolla of pea when posterior petal is outermost. In a raceme a flower develops at the upper angle (axil) between the stem and branch of each leaf along a long, unbranched axis. Justify the above statement. The ovary in such flowers is said to be superior. On receptacle two kinds of florets are present: . Sweet pea definition is - a widely cultivated Italian legume (Lathyrus odoratus) having slender usually climbing stems, ovate leaves, and large fragrant flowers. The basis for their diversity comes from their incredible reproductive success in a wide variety of habitats. 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 . Among China rose, mustard, brinjal, potato, guava, cucumber, onion and tulip, how many plants have superior ovary?
