Effect of salicylic acid (SA) seeds soaking on the NaCl salt stress induced changes in soluble sugar and protein accumulation in organs of two genotypes of okra plants

Salt stress is a major challenge in agricultural system. In this study, okra seeds of two genotypes (47-7 and LD 88) were presoaked with 10-2, 10-4, and 10-6 mM salicylic acid and control in distilled water, then the soil was treated with 0, 50, 100, 150 and 200 mM NaCl. The experiment was conducted to study the effect on osmoregulating solutes such as proline, salt stress protein (glycine betaine and proline betaine)...

Evaluation of advanced bread wheat genotypes for resistance to stem rust and yield stability

Stem rust (Puccinia graminis f. sp tritici) poses a major threat to wheat (Triticum aestivum L.) production worldwide. The interaction between wheat and pathogen in presence of favorable environment can cause a complete crop failure. This study was conducted with the objective to identify wheat genotypes with resistance to stem rust with high and stable yield under four environments in Kenya. Forty wheat genotypes were...
