Group # III. Capsule is, more commonly, a common name for all dehiscent syncarpous fruits with three or more carpels and examples (Fig. 457C) and Anona reticulata the berries become very fleshy and being crowded together on a thick thalamus form a complex single fruit. Seeds are attached irregularly and the calyx per­sists on the top. 458A), the thick club-shaped rachis has the flowers arranged on it. 2 Raspberry (Rose Family) Simple, Aggregate, or Multiple Fruit? This is seen specially in the Mimoseae subfamily of Leguminosae as in Acacia, Mimosa, etc. Pineapple (Bromeliad Family) Simple, Aggregate, or Multiple Fruit? The seeds at first remain attached to the placenta but, later on, become detached and embedded in the pulp. They can be classified into simple, aggregate, multiple, and accessory fruits. 306) is also an aggregate of achenes. Similarly, the persistent calyx makes the Physalis (Fig. An aggregate fruit is named according to the nature of the fruilets: Follicles rarely occur singly as they result from flowers with apocarpous multiple gynoecium. Each of the flower produces a fruit, but these all mature into a single mass to form the composite fruit. Strawberry (Rose Family) Simple, Aggregate, or Multiple Fruit? 445) which is falsely four-chambered and develops a gynobasic style. A multiple fruit (e.g., pineapple and mulberry) develops from the ovaries of many flowers growing in a cluster. The stimulus of fertilization not only develops ovules into seeds but also brings about other changes in the flower and even in the inflorescence. Horticulturists are always trying to induce partheno­carpy in more and more varieties of fruits. In pears and other pomes, the edible flesh is a swollen part of the stem, and the fruit is the seed-bearing core. 457A) and Polyalthia longifolia (Fig. Experts are waiting 24/7 to provide step-by-step solutions in as fast as 30 minutes! The walnut (fuglans regia—Fig. 459B; where the coenanthium develops achenes on the open receptacle. See also. 456) is an example of an aggregate of drupes. Pomes, such as apples and pears, are also accessory fruits: the core is the true fruit. Usually, all the parts of the flower except the ovary wither away. The contents of these parenchyma cells also change. 439E). The hip of rose (Fig. 439) met with are: (1) Loculicidal—when each loculus splits along the middle of its back (i.e., dorsal suture) as in the families Mal­vaceae (cotton, lady’s finger, etc.) The endocarp projects inwards forming distinct and sometimes separable chambers while the epicarp and mesocarp are fused together forming the skin. 436). The placenta and, possibly, the inner layers of the pericarp become pulpy and edible. Many foods are botanically fruit but are treated as vegetables in cooking. True fruit (pericarp) develops from the wall of the ovary and any other tissue involved is considered accessory. Chapter 37.3, Problem 1C. Cashew-nut (Anacardium Occident ale—Fig. (5) Porous—when dehiscence gives rise to a number of pores on the top of the ripe ovary through which granular seeds are liberated by censer mechanism (explained in Chapter XIII) as seen in the poppies (Papaver—Fig. Also called: false fruit, pseudocarp. There may be capsules from inferior ovaries as well (e.g., Iris of Iridaceae and Canna of Cannaceae) but these are sometimes given a separate name, diplotegia. and Acanthaceae (Andrographis, Adhatoda, etc.). Betel-nut may also be considered as a fibrous drupe like coconut although its endocarp is not so hard. Chapter 37.3, Problem 7LO. What is the significance of transpiration? 4. 459A), the female flowers within the closed receptacle (rachis) of the inflorescence develop achenes giving rise to a multiple fruit of achenes. The pericarp is fused with the seed coat as seen in the cereals. 439D), and may be seen in cock’s comb (Celosia cristata), Amaranthus gangeticus and other plants of Amaranthaceae. If on dehiscence the fruit splits up into pieces or valves, the dehiscence is called valvular. The spongy thalamus of lotus (Nelumbo — Fig. While dehiscent fruits are all dry, indehiscent fruits may be dry as well as fleshy. Calotropis (Fig. 470B) breaks into five cocci as it is formed of five carpels. accessory fruit A fruit, such as the pear or strawberry, that develops from a ripened ovary or ovaries but also has tissue derived from part of the plant outside the ovary. Multiple fruits consist of the gynoecia of more than one flower and represent a whole inflorescence, such as the fig and pineapple. 5 Angiosperm Phylogeny & Diversity 1. The various types of capsules show different types of dehiscence. The second importance of the fruit is in the dispersal of seeds. Silicula is a variation of the siliqua which contains fewer seeds and is much shorter (as broad as long) and flattened. Dry fruits include the legumes, cereal grains, capsulate fruits, and nuts. A multiple fruit or composite fruit develops from an entire inflorescence i.e., from a cluster or group of flowers into an entire fruit. Parthenocarpic fruits are, necessarily, seedless. 458B) there is a similar structure but the ovaries are not so conspicuous, the edible portion being formed more by the rachis, perianth and bracts. These changes may also be associated with structural changes within the ovary, viz., a multilocular and multiovular ovary may change into a unilocular and one-seeded one by the dissolution of some partition walls and non-development of some ovules. Multiple fruits, such as pineapple, form from a cluster of flowers called an inflorescence. One or the other of epicarp, mesocarp and endocarp may sometimes be differentiated or they may form a pulp in which the seeds are embedded. 452) and Limonia acidissima of Rutaceae. When ripe, some fruits remain fleshy and pulpy while others dry up becoming papery or stony. Types of dehiscence (Fig. In Anona squamosa (Fig. 363) of Ranunculaceae three fruits develop from each flower while Calotropis (Fig. Distinguish among simple, aggregate, multiple, and accessory fruits. … In this article, we propose to discuss the three groups of fruit. Strawberries Defined Strawberries develop from a white flower to a flavorful, fleshy receptacle. Botany. Define accessory fruit. 440) is constricted between the seeds and usually breaks up into bits containing one or more seeds. These present a dry pericarp at maturity and may be: The small one-seeded fruit of Gramineae developing from a superior monocarpellary ovary represents this type. If each broken piece encloses within it one or more seeds then the dehiscence is schizocarpic. Fruits are the reproductive structure of a plant which are developed from the ovary and accessory tissue. Fruits of Shorea (Fig. 454A) and Magnolia grandiflora (Fig. They become charged with vegetable acids, sugars and often different flavoring matters. Just classify whether it is simple, multiple, aggregate or accessory fruit? The fruit of date (Phoenix sylvestris) is some­times considered as a one-seeded berry in which the endocarp is thin and papery. They are: (1) Simple Fruits (2) Aggregate Fruits and (3) Multiple or Composite Fruits. In simple words we can say that - Fruits of individual flowers closely packed to form a single fruit.
