Germination And Growth

Iron deficiency is one of the limiting factors of plant growth. In recent years nanotechnology has attracted attention to producing forms of iron that are available to plants. Chitosan, which is widely used in agriculture due to its unique properties, has metal-binding abilities. We decided to study nanomagnetite and chitosan's combined action to improve seed germination and growth of wheat (Triticum aestivum L.). The thumbnail method was used in the study. The seeds were treated with magnetite suspension and chitosan solutions before planting. An increase in plant growth, root, and shoot length of plants was found in all seed treatment methods (chitosan, nanomagnetite, and combined action). This increase was significantly dependent on the concentration of chitosan. However, chitosan and magnetite combination was 1.3 times more effective for seed germination than pure chitosan or magnetite. A mechanism based on chitosan's ability to promote the better transfer of iron ions to plants is proposed. However, further investigation for the optimization of chitosan/magnetite proportions for improving seed growth is required.

Salinity decreased seed germination, the length, fresh and dry weight of the root and shoot, chlorophyll and carotenoid contents of wheat. The proline content was increased by salinity. The application of salicylicand gibberellic acids, was found to alleviate the adverse effects of salinity stress on the above parameters. DOI: http://dx.doi.org/10.3329/bjb.v41i1.11079Bangladesh J.

A family of fifteen quaternary ammonium salts (QAs), bearing the 1,2-bis(4-pyridyl)ethane core, were obtained using for the first time two different green methods, such as microwave (MW) and ultrasounds (US) irradiation, with very good yields and in much shorter times compared to the classical method, and an assay on their antimicrobial action against Escherichia coli (E. coli) was carried out. While 12 to 24 hours were required for complete alkylation of 1,2-bis(4-pyridyl)ethane by reactive halogenated derivatives in anhydrous solvent under reflux conditions, MW and US irradiation reduced the reaction time and the desired products were achieved in a few min. One of the aims of this study was to evaluate the antibacterial potential of the synthesized QAs against pathogenic bacteria, along with their impact on germination activity of wheat seeds (Triticum aestivum L.). The antibacterial activity of the QAs against Escherichia coli was explored by determining the minimum inhibitory concentration (MIC). The MIC values varied from 0.312 to 2.5 mg/mL, highlighting the lowest values attained for the derivatives containing methoxy, chlorine and benzofurane functional groups. The viability of aerobic bacteria was determined with the Tetrazolium/Formazan Test, a method that was found to be the best alternative approach with respect to the difuzimetric method. Seeds of Triticum aestivum L. were used for the evaluation of the germination indicators, such as seed germination (SG), the relative seed germination (RSG), the relative radicle growth (RRG), and the seed germination index (GI). The toxicity studies of QAs 1, 4 and 7, at two different concentrations, showed no inhibitory effect on seed germination.
