Five cultivars of wheat (Triticum aestivum L.) were evaluated for effects of weathering by subjecting windrowed grain to varying periods of exposure in a 2-yr study. Moderate amounts of precipitation caused a significant reduction (5%) in test weight affecting density and packing efficiency about equally. Cultivars differed in test weight loss with Neepawa showing the largest reduction of 2.9 and 4.2 kg hL−1 in successive years. Cultivars also differed in susceptibility to bleaching, the primary cause of grade loss. The 1000-kernel weights decreased significantly (1.4%) in only 1 yr. Grain hardness decreased approximately 8% with delayed harvest at similar rates for all cultivars. The hard-grained Glenlea and RL4137 were the most resistant to test weight loss and bleaching, indicating that selection for improvement might be possible.Key words: Harvest delay, weathering, wheat, test weight, seed size, grain hardness

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.

The protective effects against drought stress of the endophytic bacterium Bacillus subtilis 10-4 were measured by studying the priming response in two wheat (Triticum aestivum L.)—Ekada70 (E70) and Salavat Yulaev (SY)—lines, tolerant and susceptible to drought, respectively. B. subtilis 10-4 improved germination and growth parameters under normal conditions in both cultivars with the most pronounced effect observed in cv. E70. Under drought conditions, B. subtilis 10-4 significantly ameliorated the negative impact of stress on germination and growth of cv. E70, but had no protective effect on cv. SY. B. subtilis 10-4 induced an increase in the levels of photosynthetic chlorophyll (Chl) a, Chl b, and carotenoids (Car) in the leaves of cv. E70, both under normal and drought conditions. In cv. SY plants, bacterial inoculation decreased the contents of Chl a, Chl b, and Car under normal conditions, but pigment content were almost recovered under drought stress. B. subtilis 10-4 increased water holding capacity (WHC) of cv. E70 (but did not affect this parameter in cv. SY) and prevented the stress-induced decline in WHC in both cultivars. Notably, B. subtilis 10-4 increased endogenous salicylic acid (SA) concentration in both cultivars, especially in cv. E70. Moreover, B. subtilis 10-4 reduced drought-induced endogenous SA accumulation, which was correlated with the influence of endophyte on growth, indicating a possible involvement of endogenous SA in the implementation of B. subtilis-mediated effects in both cultivars. Overall, B. subtilis 10-4 inoculation was found to increase drought tolerance in seedlings of both cultivars, as evidenced by decreased lipid peroxidation, proline content, and electrolyte leakage from tissues of wheat seedlings primed with B. subtilis 10-4 under drought conditions.
