he increasing demand of water in agriculture has compelled to search alternative source of water which could prove more economic and effective. Therefore, this investigation was carried out to study the effect of sewage effluents on Khaya senegalensis seedlings as well as on soil properties after 6, 12 and 18 months of plantation. The primary effluent treatment was highly significant (P < 0.0001) for the growth parameters of K.

Nitric oxide (NO) and salicylic acid (SA) are well known as signaling and ubiquitous bioactive molecules that play a key role in tolerance of plant to abiotic stress by regulating the various plant cellular mechanisms. Therefore, the present experiment was conducted to study the interactive effect of NO and/or SA in tolerance of wheat (Triticum aestivum L. cv. Samma) under cadmium (Cd) stress.

Like other abiotic stresses, boron (B) toxicity is an important environmental constraint that limits crop productivity worldwide. B toxicity alters many physiological processes necessary for plant survival. The aim of the present study was to investigate the individual and combined effects of calcium (Ca) and B on morphological and physiological attributes of radish (Raphanus sativus L.) under normal and boron-toxicity conditions. The application of 30 mM Ca and 0.5 mM B, alone and in combination, enhanced plant growth, physiological and biochemical attributes.

Agricultural biotechnology is very familiar with the properties of nanomaterial and their potential uses. Therefore, the present experiment was conducted to test the beneficial effects of nanosilicon dioxide (nSiO2: size- 12 nm) on the seed germination of tomato (Lycopersicum esculentum Mill. cv Super Strain B). Application of nSiO2 significantly enhanced the characteristics of seed germination. Among the treatments, 8 g L−1 of nSiO2 improved percent seed germination, mean germination time, seed germination index, seed vigour index, seedling fresh weight and dry weight.

esearch into nanotechnology, an emerging science, has advanced in almost all fields of technology. The aim of the present study was to evaluate the role of nano-silicon dioxide (nano-SiO2) in plant resistance to salt stress through improvement of the antioxidant system of squash (Cucurbita pepo L. cv. white bush marrow). Seeds treated with NaCl showed reduced germination percentage, vigor, length, and fresh and dry weights of the roots and shoots.

Vicia faba L. (faba bean) is an important legume and is cultivated essentially as a cool-season crop. Changes in sowing dates and lack of precipitation expose faba bean crop to drought and heat stresses. The gradual rise in global temperatures owing to climate change is likely to exacerbate the detrimental effects of hot and dry climatic conditions on faba bean cultivation. High temperature stress is particularly damaging to faba bean during the flowering period, when the viability of pollen is critical for successful reproduction.

Drought stress is one of the major abiotic stresses that are a threat to crop production worldwide. Drought stress impairs the plants growth and yield. Therefore, the aim of the present experiment was to select the tolerant genotype/s on the basis of moprpho-physiological and biochemical characteristics of 10 Vicia faba genotypes (Zafar 1, Zafar 2, Shebam, Makamora, Espan, Giza Blanka, Giza 3, C4, C5 and G853) under drought stress.

Heat stress adversely affects the growth and yield of faba bean crop. Accumulation of ClpB/Hsp100 class of proteins is a critical parameter in induction of acquired heat stress tolerance in plants. Heat-induced expression of ClpB/Hsp100 genes has been noted in diverse plant species. Using primers complementary to soybean ClpB/Hsp100 gene, we analyzed the transcript expression profile of faba bean ClpB/Hsp100 gene in leaves of seedlings and flowering plants and in pollen grains.

We cloned and characterized the full-length coding sequence of a small heat shock protein 17.9 gene from faba bean encoding 160 amino acids and containing the conserved α-crystallin domain at the C-terminus. Homology and phylogenetic analysis suggested its proximity with the class II sHsp members of fabaceae family. Therefore, we name this gene as VfHsp17.9-CII. The VfHsp17.9-CII transcript showed a clear heat stress induction pattern in leaves of young seedlings and flowering plants.
