ornithine is a non-proteinogenic amino acid, which plays an essential role in the metabolism of plants. regard to the chirality of the molecule, physiological response of the plant cells to its two enantiomers have not been widely investigated yet. in the present study, suspension-cultured tobacco cells were treated with 1 mm of d- and lenantiomers of ornithine in normal conditions as well as u...
to evaluate the reaction of some wheat advanced lines and cultivars to yellow rust at seedling stage, seeds of 200 accessions were planted in 5cm diameter pots (4-6 seeds per pot) in greenhouse. the seedlings were inoculated with fresh harvested urediniospores of two different races of puccinia striiformis f.sp. tritici (134e134a+ from karaj and 134e142a+ from maragheh, iran) when the first see...
Quantifying genotype × environment interaction effect and yield stability under different environmental conditions is very important challenge in plant breeding programs. The aim of this study was to quantify genotype × environment interaction effect on grain yield and grain yield stability of barley promising lines in temperate regions of Iran. Nineteen promising barley lines (G1-G19) along wi...
silica-bonded n-propyldiethylenetriamine sulfamic acid (spdtsa) is employed as a recyclable heterogeneous solid acid catalyst for the synthesis of benzopyrano[2,3-d]pyrimidines through one-pot condensation reaction of salicylaldehydes, malononitrile and secondary amines at room temperature under solvent-free conditions. spdtsa showed much the same efficiency when used in consecutive reaction ...
