Each male flower is reduced to a solitary stalked stamen. case, main am of the inflorescence bears small or spikelets. Hut later becomes siMple racetile due to elongation of its axis. The leaves are more loosely layered and less tightly packed than green or red cabbage, although its uses are similar. But later it becomes uniparous which develop whorls of sessile flower forming verticillaster. An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Usually a whorl of leafy bracts is found at the base of branches and also at the bases of flowers arranged in umbellate way. Most flowers develop scorpioid cyme inflorescence. It has following forms: I. Panicle of spikelets: In this case. Therefore. In this inflorescence the primary axis remains comparatively short, and it bears at its tip a group of flowers which possess pedicels or stalks of more or less equal lengths so that the flowers are seen to spread out from a common point. It has apical opening guarded by scales. Example: Ettphorbia helioscopht. The oldest flower is in the centre and ends the main floral axis (peduncle). There are two forms of uniparous chyme: Scorpioid cyme: In this case, new daughter axis develops alternatively, i.e. Example: pahn, Compound Capitulum: In this case, each capitulum consists of secondary capitulum. collect together to form inflorescence to attract insects. Most flowers develop scorpioid cyme inflorescence. The lower or older flowers possess longer stalks than the upper or younger ones, e.g., radish (Raphanus sativus), mustard (Brassica campestris), etc. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, … In this type of inflorescence the main axis or receptacle becomes suppressed, and almost flat, and the flowers (also known as florets) are sessile (without stalk) so that they become crowded together on the flat surface of the receptacle.

The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in … Each head of flowers is encircled… Cyathium . The flowers arise from each branch forms secondary umbel or partial umbel. paired secondary axis start as hiparous. (i) With the main axis elongated, i.e., (a) raceme; (b) spike; (c) spikelets; (d) catkin and (e) spadix. paired secondary axis start as hiparous. But later it becomes uniparous which develop whorls of sessile flower forming verticillaster. The main axis of the inflorescence together with the latest axes, if present, is termed as the peduncle. Example: grasses etc. 121 The Valley Library Corvallis, OR 97331-4501. If bracts are present at the base of each secondary umbel, these are called involucel.

Inflorescence | Periodic Phenomena | Flowers | Prueba ... ... from wikipedia The inflorescence in which main axis develops lateral flowers and continues to grow indefinitely unto last flower is called racemose inflorescence. Therefore, such type of inflorescence is called umbellate cymose head. In this inflorescence the main axis remains comparatively short and the lower flowers possess much longer stalks or pedicels than the upper ones so that all the flowers are brought more or less to the same level, e.g., in candytuft (Iberis amara). Example: thalis. The main axis ends in a central reduced female flower. Verticillaster 6. The flowers are borne in basipetal succession. The former whorl of bracts is called involucre and the latter involucel. The lateral and succeeding branches again produce only one branch at a time like the primary one. Uniparous cynic may he coiled or spiral at first. spikelets are arranged on a. : In this case. Privacy Policy3. The main axis of inflorescence is called, leafless peduncle arising from the ground level is called. Example: poppy.

Only one daughter axis is produced below this flower. The male catkin falls off as a whole after flowering. The dry spike which has one or few sessile flowers is called spikelets. Spike let is urrounded b a special bract at the base called ghillies. Therefore. this case, new daughter axis develops on the same side. The various forms of racemose inflorescence may be described under three heads. Example: Euphorbitt helioscoplo.’, Panicle of short cymes: It is very dense and regular in shape. The daughter axis again ends in a flower and each gives two nev daughter axes. In this case, two types of flowers are present in the capittila. A terminal flower is never formed. ), etc. Homogamous: In this case, all tlov.ers are of same kind. flower ripens first and then male ripens.
