Nut (botany)

“ Chase has to say, or otherwise we might as well quit now and raise seedling nuts to the best of our ability and sell them to the commercial crackers and let it go at that. But, if we do that, what's the use of searching out better varieties?
Dr. Cross: Mr. Chairman: I believe that if a nut acceptable to the home consumer, one which extracts easily and is attractive and palatable and is productive—if that type of nut is scored and comes to the attention of a sufficient number of growers, then I think the commercial people will utilize it. ”

“ A study of the matter, however, has shown that the number really needed is very much less, and the more that nuts are examined the more it seems possible to make one table answer for a number of species and have the number of points a nut receives indicate to a certain extent its value as a nut to grow, and not simply the value of a given variety of a certain species. ”

“ A nut is a seed, and a seed, normally, is an embryo plant asleep. To keep a nut-seed asleep and safely resting against the favorable time when it may awake, arise and go forth, as a vigorous seedling bent upon a career of earth conquest, requires no great or unusual attention and care save that which is necessary to maintain such conditions as will insure the complete maturing, ripening and curing of the seed, its protection against the ravages of rodents or other nut-eating animals, undue moisture and an unfavorably high temperature. ”

“ The causes that have made the use of certain nuts unprofitable commercially, should be studied with the view of correcting these stumbling blocks. For example, the freeing of the horse-chestnut from its poisonous saponins and enable us to use this starch rich nut as food is well within the range of possibility as indicated by experiments conducted in Austria during the war. Why do nut oils tend to become rancid easily and can this tendency be remedied? Is the freeing of the acorn and its tannin and other objectionable substances a practical consideration? ”

“ Yield and size of nut while of major importance are not the only criteria for appraising the value of a nut variety. In filberts, such points as ease of husking, amount of fibre and, of course, quality must be considered. Also, as in other nuts, thickness of shell and proportions of kernel to shell are quite important. Vigour and hardiness of bush and hardiness of flower, male and female, are assumed, as without these high yields are not to be expected. ”

“ The nut, inside its germ-proof shell, is solid nutriment of the purest sort, the very quintessence of nutrient value, sunlight in cold storage. The nut represents food energy in its most delectable and concentrated form.
From an economic standpoint, the nut leaves flesh foods so far behind that they are almost out of sight.
Experiments to determine the digestibility and nutritive value of nuts were conducted several years ago by the eminent Professor Jaffa of the University of California. ”

“ Both he and I have been for some years working at the problems of nut growing. But it is only this year that we seem to have overcome the difficulties of grafting and budding nut trees. We have the greatest faith in the future success of nut growing, but we do not know how long it will be before we shall know just what varieties of nuts to plant ourselves, least of all to advise others to plant, with any certainty of success. For the man, however, who realizes that nut growing in the North is still in the experimental stage, we have no end of information and advice. ”

“ Nuts are the most important of all tree crops because they are the richest natural food substance known. A nut is Nature's supreme effort to pack as much nourishment as she can into the smallest possible space for the nourishment of the future young plant. That some people are aware of these food values is evidenced in the nationwide tree balloting now being conducted by the American Forestry Association for the selection of a national tree. In this voting nut bearing trees are in the lead. ”

“ Let us rededicate ourselves to the problem of getting the "super-nut." Let us explore these new fields of nut germ plasm which lie all about us, pull these old nuts apart genetically and recombine their good with the good of other nuts into new varieties. If we should fail 10,000 times and succeed once, success would be cheap. ”

“ It is only in the best filled nuts that highest quality, flavor, and oil content are found.
The degree to which nuts are filled or how well the kernels are developed at harvest is determined by a rather large number of interrelated factors: (1) Size of crop, or ratio of number of leaves per nut; (2) average size of nuts; (3) condition of leaves; (4) amount of second growth of the trees; (5) size of preceding crop and how well the nuts produced were filled; (6) disease and insect injury to the nuts; (7) weather conditions; (8) heterosis or effect of cross-pollination on embryo size. ”

“ Well, we can do that by selecting from seedling nuts, or we can make controlled pollinations, crossing different varieties, or varieties of different species, planting the nuts or growing new trees and then selecting out of them those that have the desirable characters.
But the first thing that we have got to do after we have either selected the nut or made the hybrid and selected the nut is to evaluate the nut as to whether it does have the first character, or proper characters, that we ought to have in the nut. Does the crop ripen evenly? ”

“ The nut must be of fair size, of good flavor, thin to medium thickness of shell, well filled, and of good cracking quality—that is, the conformation of the shell and kernel must be such that a large percentage of the kernels can be taken out as whole halves, and the convolutions of the kernels must be wide enough that the partitions do not adhere to them. When all of these qualities, both of the tree and nut, can be combined, we then have a desirable tree from which to propagate, and it is very surprising how few come up to the standard. ”

“ All but one of our most important nuts—almonds, filberts, hickory nuts, pecans, and walnuts—are oily nuts; and well filled kernels contain from 50 to 75 percent or more of oil, depending upon the species. Chestnuts are starchy nuts and contain less than one percent of oil. The relationship between the degree of filling and the composition of the kernel in oily nuts is outstanding, in that the better filled nuts have a higher content of oil and a lower content of protein, carbohydrates, water, and undetermined constituents than do poorly filled nuts. ”

“ If you take the raw nuts three days cured rapidly where the air can circulate over and under, the quality is excellent raw, and I have those nuts cured for three days in cellophane bags on cold storage that can be sold throughout the year. Those nuts must be heated enough to stop the deterioration, whatever it is. It may be a physiological condition, I am not sure, it may be a vitamin reaction, I am not sure, but when the nut dries too fast it turns white on the inside, gets hard, loses its flavor, and it is no good. ”

“ I have yet to see a tree growing in the Rochester area bearing as large a nut as those grown in the southeast, and all the large nuts I have tasted did not seem to be as sweet as ours. Probably the old saying "the smaller the nut, the sweeter the nut" is true. Of course these are all seedling trees, but by this time we should know whether size of nut and sweetness of kernel are determined by climate or individual trees.
Our largest trees are eleven-year old seedlings of unknown origin. One is, I believe, outstanding. ”

“ President Morris: We have got to get away from the idea that we are going to find the best hickory nut or the best walnut or the best nut of any kind in the largest nut. Nature spreads out just so much material in the way of flavor and good quality of a nut, and if it is in a large nut, those good qualities are spread out thin; if it is in a small nut, they are concentrated. ”

“ The other nut trees suitable for roadside planting, are not specially attractive to mankind for their fruits, as heretofore used or utilized, but may eventually become so under modern methods of cooking or proper treatment. In their raw state, however, all are edible and also palatable to most people, but their chief food value today, is to provide rich provender to domestic animals and birds, or the desirable wild life of the woodlands, all of which devour them eagerly, adding quickly to their weight and greatly to their quality and flavor of their flesh. ”

“ It is of a tough fleshy consistence, but when ripe splits open, and shows the dark-brown nut within, covered with the crimson mace, and is then a most beautiful object. Within the thin, hard shell of the nut is the seed, which is the nutmeg of commerce. ”

“ It is, frequently, difficult to positively identify a nut as to species without having leaves, buds, bark and husk for examination and in most instances the judges did not have these. No nut is noted as a hybrid unless it has been proven so by evidence which it is believed is beyond question, yet there are a number of nuts noted as pure species which later may be proved to be hybrids. This is particularly so in the case of the hickories. ”

“ Several varieties of nuts are used for the making of nut butter, and this food is a very excellent substitute for meat.
Certainly nuts have material advantage over a good many foods. They keep indefinitely. They never putrefy. They are not infested with harmful bacteria. You can never get tape-worm or any other parasitic trouble, which occasionally follows the eating of infected food.
I am glad there are societies organized to propagate the nut. A prominent concern of New York City is very active in promulgating the value of the nut, and is encouraging the planting of nut trees. ”

“ All the nuts are medium sweet to sweet and all of them fall free of the bur. I think the most significant thing is that at least 12 of the trees have nut characteristics so near alike that they are about indistinguishable, which certainly makes them a good source of seed. ”

“ The resistant varieties show great promise as nut producers, coming into bearing when three or four years old from seed and producing abundant crops of handsome nuts, of excellent quality, four to six times as large and heavy as those borne by the chinquapin parent, ripening in early September before chestnuts of any kind have appeared in the market. These nuts have thicker shells than other chestnuts, are much less subject to attacks of the chestnut weevil and preserve their fresh and inviting appearance longer when gathered. ”

“ Of course, we got a lot of self-pruning and a lot of competition, as we would in forests by the trees growing up and competing with each other and reaching for height and light. Some of them died and some were so badly suppressed that they failed to make any growth at all. But there is one tree that we still have in that orchard that we are proud of, not from the standpoint of nut production, nor does it produce a very good nut as far as the human taste is concerned. But it has made a single stick that far surpasses any other tree we have in the orchard. ”

“ In this region, also ground acorns are made into bread with cereal flours and in this form is a common food. The hazel or filbert nut is also seen in the form of flour on the shores of the Black Sea. Races living in the tropics have utilized the many varieties of nuts indigenous to tropical climes such as the coconut, Brazil nuts, Java almond, Paradise nut, candle nut and African cream nut. In the Orient, the lichi, ginko and water chestnut, and in Italy and India the varieties of the pine nut are used to considerable extent. ”

“ We find it necessary to treat the seed, of course, before we plant it. Many of you people, of course, go into the spraying end of it before the nut ever develops. We haven't the time or the money right now to go into it that way, so we try to take care of the nut after we collect it and bring it in. ”

“ Nut trees will grow on land on which no other crop will grow and which is even worthless for grazing. The piñon flourishes in the bleak and barren peaks of the rockies.
The nut should no longer be considered a table luxury. It should become a staple article of food and may most profitably replace the pork and meats of various sorts which are inferior foods and are recognized as prolific sources of disease. ”

“ The shrub in itself has beauty, and it bears nuts sometimes as large as those of the average shagbark hickory. The kernel is of good quality, but the shell is so thick that these nuts are chiefly attractive to squirrels and to men who are out of work. I do not know the origin of the nut which is known in the market as the Barcelona hazel, but I imagine the plants bearing this nut are derived from the Corylus pontica. (Specimens of branches and nuts of various species and varieties of hazels are now passed about in the audience.) ”

“ One mistake we must not make is not to be too sure of the value of a nut because it is large, thin-shelled and has a fine flavor but is a poor cropper. The nut that produces a very heavy crop is the valuable nut. Thus McAllister hican and the Stabler black are worthless because of their extremely thin crop.
Another nut that looks large and excellent on the tree is the Ohio black walnut, whose huge dirty hull and small nut condemns it. I like thin-hulled nuts that come out clean. ”
