Book Description
Excerpt from The Seed Coats of Certain Species of the Genus Brassica One of the troubles with which the seedsman has to contend is the complaint that he has sold turnip for cabbage or cauliflower seed, or the seed of a wild and weedy mustard for that of turnip or ruta-baga. The seedsman may have furnished the seeds in good faith, but he may have been deceived by the grower or by the wholesaler. It is, how ever, seldom possible to determine how far the trouble is due to care lessness on the part of the planter and inhow far the seedsman is at fault. The seed bought has all been planted and the seedsman may insist that from other lots taken out of the same bag satisfactory results were obtained. Even when the purchaser has saved some seed, it is impossible without another season's test to determine what the seed really is. In external appearance the seeds of the different species and varieties of this genus are so similar that it is at all times a difficult matter to certainly identify a given lot, and it may be wholly impossible to do so. The resemblance between the seeds of cheap and of high-priced Bras sicas has always tempted certain seedsmen to mix more or less of the one with the other. This was at one time carried so far in England that factories were established where seeds of cheap Brassicas were heated to destroy their germination so that the fraud might escape detection. This practice was stopped by the adulteration of seeds bill which passed Parliament in 1869. While it is not difficult for an expert when examining a large sample of seed to pronounce it cab bage, rape, or mustard, it is impossible for him to pronounce upon mixtures, and even determinations of pure samples may be open to doubt. Fortunately we possess in the structure of the seed coat a means of identification by which most of the species studied may be readily distinguished. This method has been employed by various investigators, mainly for the purpose of determining the seeds used in the preparation of oil cakes, and the results have found their way into most pharmacopoeias.
