| Abstract | It is well known that seeds deteriorate more rapidly in humid than in arid climates. Under dry conditions some agricultural seeds may be stored for 10 years or more without sufficient loss in viability to make their use unprofitable. In a previous study, Robertson and Lute ^ found that wheat, oats, and barley stored in a dry room for 15 years retained over 80 percent of their original ability to germinate. In a humid atmosphere, these seeds may lose as much in a few months. In humid regions the detrimental effect of moisture presents a problem of economic importance when seeds are stored for long periods. The first step in solvmg this problem is, obviously, a study of the tolerance of seeds to atmospheric moisture. If it were known how much moisture the seeds would tolerate for a given length of time at a given temperature, this information could be used as a guide in selecting storage conditions. In an attempt to solve this problem an experiment was set up in 1932 in which the effect of atmospheric humidity on rate of loss in viabihty, respiration rate, and moisture content of wheat {Triticum aestivum L.), oats (Avena sativa L.), and barley (Hordeum vulgäre L.) was studied. Respiration rate was studied primarily to see how closely respiration was related to loss in viability. Moistm^e content was determined because this variable is a function of the hmnidity and may be used as an index of humidity where no direct measurements are available. |
