Question for the hypothesis shown: Will the viability of maize grains increase when treated with short duration of microwaves?
Hypothesis: Unhydrated maize grains that are mucrowaved for short periods will show greater viability than those not microwaved. Hydrated maize gains will quickly loose their viability when microwaved
Results: 5 sec- 66.66% viability, 10 sec- 21.43% viability, 15 sec- 14.28% viability, 30 sec- 0% viability, 60 sec- 0% viability.
Describe the effect of microwaving on maize grain viability before tetrazolium staining. How do the results compare to our hypothesis? Explain. Question for the hypothesis shown: Will the viability of maize grains increase when treated with short duration of microwaves?

Explanation / Answer

Seed viability is affected by availability of moisture. Microwaving for shorter duration provide the enough heat to open the germ pores of the seed coat which in turn allow the enter of water into the seeds and to begin the process of germintation. However, microwaving for longer duration makes the water present in the seeds to boil leading to drying of the seeds. These seeds do not germinate even in presence of water.
