CARROT . See also:

Wild carrot, Daucus carota, a member of the natural See also:order See also:Umbelliferae, grows wild in See also:fields and on roadsides and See also:sea-shores in See also:Britain and the See also:north temperate See also:zone generally of the Old See also:World. It is an See also:annual and resembles the cultivated carrot, except in the See also:root, which is thin and woody. It is the origin of the cultivated carrot, which can be See also:developed from it in a few generations. M. Vilmorin succeeded in producing forms with thick fleshy roots and the biennial See also:habit in four generations. In the cultivated carrot, during the first See also:season of growth, the See also:stem remains See also:short and bears a rosette of graceful, See also:long-stalked, branched leaves with deeply cut divisions and small, narrow ultimate segments. During this See also:period the plant devotes its energies to storing See also:food, chiefly See also:sugar, in the so-called root, which consists of the upper See also:part of the true root and the short portion of the stem between the root and the lowest leaves. A transverse See also:section of the root shows a central core, generally yellow in See also:colour, and an See also:outer red or See also:scarlet rind. The core represents the See also:wood of an See also:ordinary stem and. the outer See also:ring the soft outer See also:tissue (bast and cortex). In the second season the terminal bud in the centre of the See also:leaf-rosette grows at the expense of the stored nourishment and lengthens to See also:form a furrowed, rather rough, branched stem, 2 or 3 ft. high, and bearing the See also:flowers in a See also:compound umbel. The umbel ischaracterized by the fact that the small leaves (bracts) which surround it, resemble the foliage leaves on a much reduced See also:scale, and ultimately See also:curve inwards, the whole inflorescence forming a See also:nest-like structure.

The flowers are small, the outer See also:

white, the central ones often See also:pink or purplish. The See also:fruit consists of two one-seeded portions, each portion bearing four rows of stiff spinous projections, which cause the fruits when dropped to cling together, and in a natural See also:condition help to spread the See also:seed by clinging to the See also:fur of animals. On See also:account of these projections the seeds cannot be sown evenly without previous rubbing with See also:sand or dry ashes to See also:separate them. As usual in the members of the order Umbelliferae, the See also:wall of the.fruit is penetrated lengthwise by canals containing a characteristic oil. Carrots vary considerably in the length, shape and colour of their roots, and in the proportion of rind to core. The White Belgian, which gives the largest crops, has a very thick root which is white, becoming See also:pale See also:green above, where it projects above ground. For nutritive purposes it is inferior to the red varieties. The carrot delights in a deep sandy See also:soil, which should be well drained and deeply trenched. The ground should be prepared and manured in autumn or See also:winter. For the long-rooted sorts the soil should be at least 3 ft. deep, but the Short See also:Horn varieties may be grown in about 6 in. of See also:good compost laid on the See also:top of a less suitable soil. See also:Peat See also:earth may be usefully employed in lightening the soil. Good carrots of the larger sorts may he grown in unfavourable soils by making large holes 18 in. deep with a crowbar, and filling them up with sandy compostin which the seeds are to be sown.

The See also:

main See also:crop is sown at the end of See also:March or beginning of See also:April. After See also:sowing, it is only necessary to thin the See also:plants, and keep them clear of weeds. The roots are taken up in autumn and stored during winter in a cool See also:shed or cellar.
