the use of more competitive species and cultivars in small grain cereal production may help to develop production systems that require less herbicide. this study was designed to identify root and shoot characteristics of cereal seedlings that would allow distinguishing the more competitive (mc) cultivars from the less competitive (lc) ones. two growth cabinet trials were conducted using four cr...

World cereal production and utilization The United Nations Food and Agriculture Organization (FAO, 1975) analysed production and consumption of cereals in 1970 and estimated corresponding values for 1980, 1985 and 1990 (Fig. I). In 1970, livestock ate more than 60% of the cereals consumed in the developed countries but less than 1070 of those consumed in the rest of the world. By 1990 these pro...

The study of plant exploitation and early use of cereals in Africa has seen over the years a great input from charred and desiccated macrobotanical remains. This paper presents the results of one of the few examples in Africa of microbotanical analyses. Three grave contexts of phytolith-rich deposits and the dental calculus of 20 individuals were analysed from two Neolithic cemeteries in North ...

Carboxypeptidase activity (hydrolysis of N-carbobenzoxy-l-phenylalanyl-l-alanine) is high in a number of temperate zone cereals, originating in Asia Minor (wheat, barley, oats, wild oats, rye, triticale) compared to other cereals originating in central America or Asia (maize, sorghum, rice). However, endopeptidase activity (hydrolysis of azocasein or hemoglobin) is relatively much higher in the...
