“…(4.5) 'Dry'and 'damp'seeds At room temperature 'dry' seeds of tnany species can be stored satisfactorily, but even af the optimum moisture content for storage, seeds will deteriorate wifh age, the rate of deterioration (Roberts, 1972) and metabolistn (Bailey, 1940;Edwards, 1976) increasing as fhe seed moisture content is raised. Thus the optimutn moisture contenf for dry storage represents a balance between minimizing the deterioration resulting at the moisture level of 'damp' seeds and that caused by excessive desiccation.…”

Current interest in seed hydration treattnents for the improvement of level, rate and uniformity of gennination or field emergence has revealed how little is Imown of the physiology of getmination control under water stress. This review surveys briefly the responses of seeds held at different hydration levels, from normal germination in a free water supply to seed activation without germination under slight moisture stress, seed deterioration at greater moisture stress and the damage that can be caused to seeds in very dry conditions, as well as the responses to subsequent dehydration. Inhibition of germination, though not of seed activation, at certain levels of water stress is likened to various forms of dormancy, and the mechanism governing the initiation of cell elongation is suggested as the possible key to control over germination. Several lines of evidence on cell membrane integrity and action, and their responses to external factors, point to tlie role that the membrane may play in cell elongation (and hence germination) eontrol, and membrane integrity may also be associated with the transition between seed deterioration at one hydration level and seed activation and repair at slightly higher hydration levels. Seed activation witliout germination is also considered in an ecological context.

“…Similar observations were made by Bailey (1921) with maize, by Smith & Bartz (1932) with oats, maize and mixed feeds, and by Leach (1942Leach ( , 1943Leach ( , 1944 with wheat. This work was extended by Bailey (1940) to include studies on a variety of cereals and flaxseed and by Larmour, Sallans & Craig (1944) to include sunflower seed and flaxseed. The results obtained by these authors all confirm that the chief factor controlling the rate of respiration and the heating of feeding stuffs is the moisture content of the material.…”

1. Experiments were made on the respiration of bran at different moisture levels using a continuous absorption apparatus in which the humidity of the air-stream was adjusted to be at equilibrium with the respiring bran. The rate of respiration was accelerated with increasing moisture content and was very rapid deterioration due to the high respiration rate and microbiological damage.2. Experiments were made on the storage of bran at known moisture contents in closed tins in the laboratory and also in sacks kept under farm conditions. The total nitrogen content of the bran stored in the tins appeared to increase during storage. From similar increases in total phosphorus, it is clear that the increase in total nitrogen was caused by a loss of dry matter from the stored feeding stuff, a fact which was further demonstrated by the loss in dry weight of the sacks of bran with attributed to two causes: (1) the respiration of the plant cells still active in the bran itself, and (2) the respiration of developing micro-organisms. It is evident from these experiments that fresh bran, free from insect infestation and stored at a moisture content of less than 13%, will have a very low respiration rate and will, therefore, not be liable to heating. Bran of 15–19% moisture content respires at a much faster rate and the time for which such material can be stored with freedom from heating or other types of deterioration will be limited.

“…The increase was relatively greater at lower moistures, with the breaks of the curves varying from 20% moisture at 8°C to 17% at 30°C. Two equations are required to describe these curves; (2) Y, = a1eblx, at the lower moisture range and…”

“…Considerable work has been done on other seeds and grains (2,4,6,15), but relatively little has been done on maize or corn. Bailey (1) found respiration of corn to be less affect-ed by moisture than that of wheat with the materials he used.…”
