Fighting for the Taste Buds of Our Children
No full textIn this commentary, I focus on the impacts of Indian boarding school food on American Indian foodways and community as a source of acculturation that has a lasting effects even in the present day. From the introduction of specific foods that now make up the modern diet of many American Indian communities, to the generational cycle that begins in utero, the taste buds of American Indian children are still subject to the “American Indian Boarding School experiment” that began in the late 1800s. Only American Indian communities can determine when that experiment stops.

Factors affecting the aseptic culture of Lovell peach seedlings
No full textA similarity between growth from ecotyledonized embryos (embryos with cotyledons removed), growth of excised immature embryos, and growth from non-after-ripened embryos is pointed out and the significance discussed
Chemical weed control in rose nursery fields
No full textIn these experiments of chemical weed control in rose nursery fields, cuttings were planted in t he bottom of furrows in lat e December and early January. These were irrigated twice weekly until rooted. A month to five weeks after planting, CMU, DCMU, SES, CIPC, IPC, and alanap were applied to the soil in the furrows. CMU and DCMU controlled all weeds, and the two phenylcarbamates were of only limited effectiveness. Alanap controlled the weeds but caused serious injury to the roses. Treatments of CMU and DCMU applied in April proved to be as toxic to the roses as to the weeds, while three phenylcarbamates applied at that time provided excellent weed control without damaging the roses
Rest and dormancy in garlic
No full textGarlic bulbs, both for food and for replanting, are commonly held in storage for many months. If they are planted immediately after harvest, the bulbs do not produce either roots or sprouts, and may be said to be in a state of rest. The rest decreases with time, but the rate of decrease is markedly affected by the temperature at which the bulbs are held. Experiments to determine how length and temperature of storage affect rest in garlic are described in the present paper
Comparative studies with labeled herbicides on woody plants
No full textThe spot treatments of 2,4-D*, 2,4,5-T*, ATA*, MH*, urea*, and monuron* to active phloem of manzanita, toyon, and buckeye growing in the field proved that the first two are consistently absorbed and translocated in the phloem. Peak movement followed the season’s flush growth. The other compounds were more generally carried away by the transpiration stream
Factors influencing control of the citrus nematode in the field with D-D
No full textWhen replanting citrus nematode-infested soil with susceptible crops, it usually is important to treat the soil with a 1,3-dichloropropene or other type of chemical for control of this nematode (Tylencbulus semipenetrans Cobb). Since the degree of control of the citrus nematode often is unsatisfactory, an effort was made to develop improved and highly effective methods for applying D-D type chemical in the field. The vertical diffusion pattern and efficacy of D-D for control of the citrus nematodes in a number of Yolo loam and silt loam soils were determined. When the D-D was applied at rates of 60, 90, 120, and 180 gallons per acre, 100 per cent of the citrus nematodes in the top 3 to 5 feet of soil frequently were killed. The amount of the chemical applied and the soil type treated affected greatly the degree of control. The effect of placement depth of the D-D in the soil, moisture content of the soil, time of year applied, and of some post-irrigation treatments on control were determined
Stability of variety response to extensive variations of environment and field plot design
No full textThe ideal conditions upon which the usefulness of the classical field trials depend rarely exist in nature. Nor can the conditions that actually exist be sufficiently formalized by current conventional practices to provide an adequate and consistently reliable interpretation of field trials. AI large number of trials for the same strains of Hannchen barley and other crops show that field trials can be freed from the procedures which attempt, by preselection and mathematical compensations, to arrange naturally irregular conditions according to a formalized mathematical model. Simpler and more accurate procedures, based on conditions as they actually exist, can be substituted. Thus the costs and time necessary for definitive field trials can be greatly reduced. Agricultural testing programs can be accelerated, with increased confidence in the reliability of the results
Effect of gibberellin on vine behavior and crop production in seeded and seedless Vitis vinifera
No full textIn 1957, vines of Zinfandel, Red Malaga, Tokay, and Ribier grapes were sprayed, at four developmental stages, with gibberellin in a range of 0 to 25 ppm. In the spring of 1958, certain seeded varieties showed severe injury as a result of the higher concentrations of gibberellin. In 1958 and 1959, therefore, those experiments were followed up with the work reported in the present study, designed to determine the degree of recovery in vines injured by gibberellin
Analysis of 2,4-D transport
No full textDinitrophenol, anoxia, and starvation reduced the absorption and retention of 2,4-D in roots and leaves of bean, cotton, barley and soybean plants. Phloem translocation of the compound was likewise reduced. Apoplast mobility of the compound was, however, increased
Developmental aspects of field-to-field variations in selected cantaloupe characteristics (Cucumis melo L. var. reticulatus Naud.)
No full textThis paper presents observations on the week-to-week development of selected cantaloupe characteristics under several different sets of field conditions. The analysis is especially concerned with detecting the period or periods of melon development during which variations in each characteristic seem to arise. The information is presented under several headings: Time required for maturation, Development of flesh color, Melon size, Fruit shape, Surface netting, Suture netting, Ground-spot size, Flesh thickness and flesh proportion, Soluble solids concentration, and Correlation of seed number with melon characteristics. The observations recorded here may be regarded as directly related to those published by the senior author in 1964, with several of the same co-workers (Hilgardia, Volume 35, Number 16, July). The latter paper is frequently cited in the present text
