Abstract
Seeds are the major unit of propagation and dispersal of plants, fulfilling a vital biological role. They are also of immense economic and social importance to humankind, forming the harvested organ of many important crops. This importance is demonstrated by a brief consideration of yields. In 1993, the total world yields of the major cereals alone amounted to almost 2 x 109 tonnes, compared with a total yield of about 580 x 106 tonnes for all root and tuber crops (cassava, sweet potato, taro, potato etc.) (FAO, 1994). Major pulses and oilseeds accounted for a further 4 x 109 tonnes and palms (coconut and oilpalm kernel) about 48 x 106 tonnes, making a total yield for major seed crops in the region of 6–7 x 109 tonnes. This does not include the many minor crops which are grown by different communities or seeds harvested from the wild.
