Durum wheat is the most widely grown cereal in Tunisia, but its production threatened by drought, which exacerbated climate change. This study aimed to identify drought-tolerant durum genotypes from five modern varieties and six landraces a multi-environment trial at two sites (Kef Siliana, Tunisia) during three growing seasons under rainfed irrigated conditions. Six drought tolerance indices (...

For a long time, it was politically incorrect to speak about adaptation to climate change, because it presumably implies accepting defeat in the battle against evil emissions (Burton, 1994). This has changed, perhaps because scientists repeatedly pointed out that climate change cannot be altogether avoided even if we try very hard (Parry et al., 1998; Wigley, 1997), and perhaps because George W...

Drought is an important factor limiting crop production in arid and semi-arid conditions. Drought indices which provide a measure of drought based on yield loss under drought condition in comparison to normal condition was used for screening drought-tolerant genotypes. This study was conducted to determine drought tolerant genotypes with high yield in stress and non-stress conditions. Ten barle...

The purpose and objectives of the study. To determine resistance soybean genotypes to drought according indices based on analysis yield in years contrasting terms hydrometeorological conditions.
 Materials research methods. material for determining influence year conditions level average soybeans were varieties breeding numbers competitive variety test (CVT). Experiments carried out four r...

One of the possible ways to ensure future food needs of an increasing world population involves the better water use through the development of crop varieties which need less water and are more tolerant to drought. In order to study the response of twenty landraces of bread wheat to drought stress, an experiment was conducted in a randomized complete block design with three replications under t...

N-Aryl-S,S-dimethylsulfimides 3(Ar = 4-NO(2)C(6)H(4)), 4 (Ar = Ph) and 5 (Ar = 4-Tol)react with Appel salt 1 to give the corresponding N-aryl-(4-chloro-5H-1,2,3-dithiazolylidene)benzenamines 8 (Ar = 4-NO(2)C(6)H(4)), 9 (Ar = Ph) and 10 (Ar = 4-Tol) in 84, 94 and 87% yields, respectively. The reaction proceeds in the absence of base and a proposed reaction mechanism is given.

The concept of the TOL introduced by Darwin, captured in the famous single illustration of the On the Origin of Species (Darwin 1859), and used by Haeckel as the grand scheme of the history of the actual life-forms is the cornerstone of evolutionary biology and, arguably, of biology in general. For nearly 140 years after the publication of the Origin, phylogenetic trees, which were initially co...
