Cleaning crop

A crop, such as potatoes, that is used in the rotation to help suppress weeds. It does this by shading out the young weeds, which can be finally destroyed by cultivation. Cleistothecium

(Plural: cleistothecia). The entirely enclosed body containing one or more asci, typical of the Erysiphales. The cleistothecium is ruptured by the developing ascus which can then eject its ascospores. Cline

A large population covering a wide geographic area and exhibiting genetic change from one end to the other. For example, wild cocoa occurs as a cline covering the length of the Amazon River, with totally allogamous types at the river source, in the West, and a gradual change to autogamous types at the river mouth, in the East. Clone

A population in which all the individuals are descended by asexual reproduction from one parent individual. Consequently, all the individuals within a clone are genetically identical. However, some clones may contain asexually produced variants called ' sports' or mutants. vegetative propagation of plants includes the use of grafts, cuttings, suckers, tuber, bulbs, corms, setts, and rhizomes. Typical clonal crops are potatoes, sweet potatoes, yams, cassava, strawberries, hops, apples, olives, citrus, dates, sugarcane, bananas, and pineapples.
