Plant species show different responses to the elevated temperatures that are resulting from global climate change, depending on their ecological and physiological characteristics. The highly invasive shrub Lantana camara occurs between the latitudes of 35 °N and 35 °S. According to current and future climate scenarios predicted by the CLIMEX model, climatically suitable areas for L. camara are ...

Garlic (Allium sativum L.) stalk is a byproduct and normally the waste of garlic production but now is thought a good biological resource. It is necessary to utilize this resource efficiently and reasonably to reduce environment pollution and achieve agricultural sustainable development. The allelopathy of decomposed garlic stalk at different ratios (0:100, 1:100, 3:100 and 5:100) was investiga...

This study evaluated the allelopathic potential and autotoxic interference with growth and nutrient uptake of two asparagus varieties; UC157 (U) and Gijnlim (G) from USA and Europe, respectively. The two varieties were cultivated in a continuous replanting system in different rotational patterns with soil amended by asparagus root residues, and unamended soil (control) under greenhouse conditio...

In this review, the biosynthesis, catabolism, ecological significance, and modes of action of purine alkaloids particularly, caffeine, theobromine and theophylline in plants are discussed. In the biosynthesis of caffeine, progress has been made in enzymology, the amino acid sequence of the enzymes, and in the genes encoding N-methyltransferases. In addition, caffeine-deficient plants have been ...

Wheat-derived foodstuffs represent about one-fifth of the calories consumed by humans worldwide. Bread wheat (Triticum aestivum L.) is one of the most important crops throughout the world, and it has been extensively studied for its allelopathic potential. In contrast, for allelopathy in durum wheat (Triticum turgidum ssp. durum), our knowledge is partial and fragmentary. Through highlighting r...
