MESERVEY, R., 1971. The coastline fit of Africa and South America. Palaeogeography, Palaeoclimatol., Palaeoecol., 9: 233-243. It has become axiomatic that the pre-drift reconstruction of Africa and South America is to be made by fitting together the continental shelves. Although this procedure is very plausible, actually the detailed fit of the coastlines is better than that of the shelves and ...

The results of two field trials to determine the effect of ratoon stunting disease on the growth and yield of some widely grown and newly released sugarcane varieties are described. In the plant crop of a trial grown under full irrigation, the greatest reductions in yields of cane and sugar among six varieties, approximately 15%, occurred in N 14 and NC0376. In the first ratoon, the greatest re...

Plants of six wheat varieties (Damani, Hashim-8, Gomal-8, DN-73, Zam-04, and Dera-98) were grown under three water regimes i.e. 100% Field Capacity (FC), 35% FC and 25% FC. Results of this experiment showed highly significant difference among wheat varieties in all the studied traits and water stress conditions decreased them significantly. The superior variety Hashim-8 which indicated higher r...

The recent soaring cost of many basic foods worldwide has forced a new focus on many areas of policy and in Europe the issue of genetically modified crops has attracted renewed media and wider interest. The reason is that the European Union has proved resistant to almost all perceived or promoted advantages of GM crops. Environmental groups opposed to the technology gained early advantage becau...

The photosynthetic characteristics of two contrasting varieties of common bean (Phaseolus vulgaris) have been determined. These varieties, Arroz and Orfeo, differ in their productivity under stress conditions, resistance to drought stress, and have distinctly different stomatal behaviour. When grown under conditions of high irradiance and high temperature, both varieties displayed evidence of p...

The aim of this study was to determine that the total anthocyanin content (TAC) and antioxidant activity (AOA) in potato flesh with different colours grown in the Czech Republic. Four yellowor white-, six purpleand four red-fleshed varieties were grown in 2009 at two different sites (Valečov – highland, seed potato area at 460 m a.s.l., Přerov nad Labem – lowland, new potatoes area at 178 m a.s...

As a consequence of the climate change effects, chemical composition wine grapes is being altered, particularly phenolic components. For this reason, drought effect on an extensive group white and red varieties grown under semi-arid continental Mediterranean (La Mancha, Spain) was studied in 2021 vintage. The study based comparison compounds minority varieties, using other widely cultivated as ...

The use of oats in the human diet has decreased over the past 70 years. This is an unfortunate development from the perspective of human health because oats have a high nutritional value and contain many compounds, including β-glucan, polyphenols, vitamins, and unsaturated fatty acids that are able to maintain or may even improve consumer's health. In addition, oats fit into a gluten-free diet ...
