Experiment 1: Effects of acid rain on seed germination of wheat, rape, and rice seeds
Rice, wheat and rape seeds were treated with simulated acid rain at pH 2.0, 2.5, 3.0, 3.5, 4.0 and 5.0 levels for 7 days in order to understand the effects of acid rain on seed germination of various acid-fast plant. The germination test showed that seed germination was absolutely inhibited at pH 2.0 for three species. Rice and wheat seeds germinated abnormally at pH 2.5. When pH values above 3.0, percentage germination, germination energy, germination index, vigor index of rice, wheat and rape seeds increased in relation with decreased acidity levels. In contrast, the percentage of abnormal germination of rice and wheat decreased. The experiment data about physiological aspect demonstrated that water absorption rate, respiratory rate and storage reserve transformation rate of rice, wheat and rape seeds also increased with increased pH values. The storage loss of rice and wheat increased with increased pH values but that of rape decreased. Inhibition index of shoot and root length of three kinds of seeds decreased in relation with increased pH values. The amplitude difference of index of rice was lower than that of wheat, and wheat was lower than that of rape. The experiment data showed that rice had stronger fastness than wheat and rape, wheat had stronger fastness than rape under acid rain stress. (Source: http://www.ncbi.nlm.nih.gov/pubmed/15859434)
Experiment 2: Effect of Heat-Treatment of Wheat Flour on Pancake Springiness
In this experiment they test whether pancakes increase in springiness with heat treated wheat flour. Pancakes baked with heat-treated wheat flour increased in springiness (recovery from compression) and decreased in gumminess. Brabender Amylograph tests of heat-treated wheat flours (at 120°C for 0, 1.0, 2.0, 3.0, and 5.0 hr) also showed the first viscosity-increase of the flour-water slurries started at lower temperatures...
