Book Description
A study was conducted to determine the immediate effects of mechanical damage to soybean seed as influenced by a combine harvester applying different levels of threshing effort on pods and seed at different levels of moisture content. Four rows were harvested at a time, and the yield was 34 bushels per acre. A rasp bar cylinder type harvesting combine was used to harvest the seed at 16.85, 13.05 and 1.65% moisture conten, applying Threshing indices of 70, 87, 108 and 130. Visible effects of damage, evaluated as percentage of split seed, cracked coated seed, visibly uncracked seed and seed size, revealed that the interaction of seed moisture and threshing Index was of significant importance in determining the degree of injury to seed at harvesting. For any level of one of these two factors, the extent of injury was dependent upon the level of the other factor, except for cracking of the seed coat, for which the interaction failed to be significant. Decreased levels of seed moisture content and increased cracking of seed coats, and a decrease int he proportion of visibly uncracked seed. Combine harvested seed tended to be smaller than hand harvested. Physiological responses of the combine harvested seed were evaluated by the standard germination test, accelerated aging test, storage under adverse conditions, and soil emergence. Seed harvested at 16.85% moisture produced lower germination percentages and lower vigor ratings than did seed harvested at 13.05 and 11.65% moisture. Increased Threshing Index caused a decrea.

Book Description
From prehistoric times man has had a pecial s relationship with seed plants - as a source of food, materials for tools, buildings, clothing and pharmaceuticals, and for ornamenting his surroundings for his own delight (probably in that chronological order which, incidentally, also gives some indication ofthe priorities oflife). Today man's most important staple foods are derived directly from seeds as they have been since neolithic times. (It is a sobering thought, as Harlan* has pointed out, that nothing significant has been added to his diet since then. ) From those times he must have learned to collect, conserve and cultivate seeds; and the accumulated experience has been handed down. This book then is part of an ancient tradition, for here we are still primarily concerned with these skills. Seeds are plant propagules comprised of embryos in which growth has been suspended, usually supplied with their own food reserves and protected by special covering layers. Typically they are relatively dry structures compared with other plant tissues and, in this condi tion) they are resistant to the ravages of time and their environment. But resistant is a relative tenn and seeds do deteriorate: the type, the extent and the rapidity of the deterioration, and the factors which control it are important to agronomists, horticulturalists, plant breeders, seedsmen, seed analysts, and those concerned with the conservation of genetic resources.
