The effects of atrazine on growth of flax (Linum usitatissimum L.) plants and on yield, chemical composition and germination of flax seeds

Creator:: Locatelli, Eduardo Atilio
Abstract:: Reports of previous research indicated a stimulatory effect of triazine herbicides on growth, yield and protein content of plants and seeds of various species. Studies were conducted in the greenhouse, laboratory and field to investigate the effects of atrazine (2-chloro-4-ethylamino-6-a sopropylarnino- s-triazine) on growth, yield, seed composition, and seed germination...

Factors affecting the action of 1,8 naphthalic anhydride in corn treated with s-ethyl dipropylthiocarbamate (EPTC)

Creator:: Guneyli, Ercan
Abstract:: The antidote (1, 8 naphthalic anhydride) is recommended for corn protection against EPTC injury where the antidote is applied at a half percent by weight of corn seeds before planting. Studies were conducted to determine the factors affecting the action of antidote in corn (Zea mays L. var. NB 501D)...

Influence of post-harvest management practices on plant growth and seed yield of cool season grasses

Creator:: Stanwood, Phillip Charles
Abstract:: Field and controlled environment chamber studies were carried out to evaluate modes of action of post-harvest treatments on the development and seed yield of cool season grasses. Red fescue (Festuca rubra L.) was used as the primary test species. There was no difference in total biomass production of red fescue...

Physiological and biochemical factors related to the differential toxicity of 3,5-dibromo-4-hydroxybenzonitrile in winter wheat (Triticum aestivum L.) and coast fiddleneck (Amsinckia intermedia Fisch & Mey)

Creator:: Barzee, Milton Arlo
Resource Type:: Dissertation

Characteristics of two noncarotenogenic light sensitive mutants of Scenedesmus obliquus strain D₃

Creator:: Harvey, Geoffrey W.
Abstract:: Two light sensitive mutants of the green alga Scenedesmus obliquus strain D₃ have been characterized. The photodynamic nature of their sensitivity has been established, the subchloroplast site of photodamage has been investigated, and their noncarotenogenic character has been verified. The two mutants possess several similarities, although mutant L. S. -41...

Combining ability and associations of agronomic traits involving three sources of dwarfism in wheat (Triticum aestivum, L. em Thell)

Creator:: Maya de Leon, Jose Luis
Abstract:: Three genetically different dwarf cultivars of spring wheat were evaluated as potential sources of short stature to use in a wheat improvement program. The study involved a five parent diallel cross which included a semidwarf, a standard height and three dwarf cultivars. The genetic sources of dwarfism included a Norma...

Size distribution of chemically extracted quartz used to characterize fine-grained sediments

Creator:: Dauphin, J. P. (Joseph Paul)
Abstract:: Quartz is an ubiquitous component of marine sediments. Textural characteristics of this component reflect the dynamics of its transport and at the same time are indicative of its source. Quartz may be extracted from marine sediments by means of a sodium pyrosulfate fusion and hydrofluosilicic acid dissolution without significantly modifying...

The translocation of ethephon and its physiological effects on the filbert (Corylus avellena L.) during husk senescence

Creator:: Kwong, Francis Y.
Abstract:: Nut drop in the filbert is a consequence of the senescence of the husk. It is possible to accelerate this process by the application of ethephon (2-chloroethyl)phosphonic acid after the nut has abscised from the base of the husk. This study is an investigation on the physiological effects of the...

Root initiation and elongation in Douglas-fir, Pseudotsuga menziesii (Mirb.) franco, stem cuttings as related to bud and cambial activity

Creator:: Bhella, Harbans Singh
Abstract:: The relation of bud and cambial activity to root initiation and elongation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stem cuttings was studied through two successive growth cycles. Stem cuttings of current season's growth were taken periodically from field-grown Douglas-fir trees to determine: (1) origin and development of root initials; and...
