Fruits: Kinds and Terms
FRUITS: KINDS AND TERMS THE IMPORTANT PART OF THE LIFE CYCLE OFTEN IGNORED Technically, fruits are the mature ovaries of plants that contain ripe seeds ready for dispersal • Of the many kinds of fruits, there are three basic categories: • Dehiscent fruits that split open to shed their seeds, • Indehiscent dry fruits that retain their seeds and are often dispersed as though they were the seed, and • Indehiscent fleshy fruits that turn color and entice animals to eat them, meanwhile allowing the undigested seeds to pass from the animal’s gut We’ll start with dehiscent fruits. The most basic kind, the follicle, contains a single chamber and opens by one lengthwise slit. The columbine seed pods, three per flower, are follicles A mature columbine follicle Milkweed seed pods are also large follicles. Here the follicle hasn’t yet opened. Here is the milkweed follicle opened The legume is a similar seed pod except it opens by two longitudinal slits, one on either side of the fruit. Here you see seeds displayed from a typical legume. Legumes are only found in the pea family Fabaceae. On this fairy duster legume, you can see the two borders that will later split open. Redbud legumes are colorful before they dry and open Lupine legumes twist as they open, projecting the seeds away from the parent The bur clover modifies its legumes by coiling them and providing them with hooked barbs, only opening later as they dry out. The rattlepods or astragaluses modify their legumes by inflating them for wind dispersal, later opening to shed their seeds.

Maleae consists of economically and ecologically important plants. However, there are considerable disputes on generic circumscription due to the lack of a reliable phylogeny at generic level. In this study, molecular phylogeny of 35 generally accepted genera in Maleae is established using 15 chloroplast regions. Gillenia isthemostbasalcladeofMaleae,followedbyKageneckia + Lindleya, Vauquelinia, and a typical radiation clade, the core Maleae, suggesting that the proposal of four subtribes is reasonable.

Brambles are members of the rose family and of the genus Rubus. Most plants in this genus are called brambles because of the thorns on the stems but there are some thornless cultivars. The fruit is an aggregate fruit made up of many small druplets. The raspberry fruit is made up of several rows of druplets that grow around the receptacle. When ripe, the raspberry fruit easily separates from the receptacle tissue. Blackberry fruit grows around the receptacle tissue but when ripe blackberry fruit is harvested, the receptacle tissue stays inside the fruit. General Botany All brambles have a perennial root system. Bramble canes are normally biennial, and the first year, plants produce vegetative canes (primocanes).

Strawberry Plant Structure and Growth Habit E
Strawberry Plant Structure and Growth Habit E. Barclay Poling Professor Emeritus, NC State University Campus Box 7609, Raleigh NC 27695-7609 Introduction The strawberry plant has a short thickened stem (called a “crown”) which has a growing point at the upper end and which forms roots at its base (Fig. 1). New leaves and flower clusters emerge from “fleshy buds” in the crown in the early spring. From a cultural viewpoint, it is desirable in our region to have the formation of 1-2 “side stems” called branch crowns form during the late fall (Fig. 2). Each branch crown will add to the yield of the main crown by producing its own “flower cluster” or what is technically called an inflorescence. Branch crowns and main crowns are structurally identical, and an inflorescence develops at the terminal growing point of each crown (Fig. 3). Crown growth and development occur when temperatures are above 50o F (mainly in the month of October). Average daily temperatures in November below this temperature will slow branch crown formation and floral development. Row covers may be a good option in November for Camarosa to help stimulate further reproductive development. A well-balanced Camarosa strawberry plant will form 3-5 branch crowns by the time fruiting season begins in the spring. There is excellent potential for a 2 + lb crop per plant (> 15 tons per acre) when you can see the formation of 1-2 side crowns in addition to the main crown (center) in late fall/early winter (Fig. 7). In Chandler and Camarosa it is critical not to plant too early in the fall and run the risk of having too many crowns form (try to avoid the development of more than 6 crowns per plant).

Fertilization is the union of the (male) sperm nucleus from the pollen grain and the (female) egg nucleus found in the ovary. If fertilization is successful, the ovule will develop into a seed and the ovary will develop into a fruit. Seed Characteristics Seed coats are the hard outer covering of seeds. They protect seed from diseases, insects and unfavorable environmental conditions. Water must be allowed through the seed coat for germination to occur. Endosperm is a food storage tissue found in seeds. It can be made up of proteins, carbohydrates, or fats. Embryos are immature plants in an arrested state of development.
