Spectroscopy of biophysical, physiological and pathological responses of plant germplasm

Creator:: Li, Ning
Abstract:: Imaging spectra of plant tissues yield considerable potential and useful information for basic studies and agriculture practice. We constructed an imaging spectrophotometer with spectral range from 400 nm to 1100 nm, which was used to study various physiological events of plant germplasm: location of bundle sheath and mesophyll cells in...

Response of strawberry plants to manganese nutrition

Creator:: Sabharwal, Sudarshan Lal
Abstract:: The effects of manganese nutrition on growth, mineral composition, carbohydrate and nitrogen metabolism, IAA oxidase and phenols of 'Northwest' strawberry plants are reported. Growth and mineral composition response were investigated in sand culture and Hoagland's solution 2 modified to contain 0.0, 0.5, 2.5, 12.5, 25.0, 62.5 and 125.0 ppm substrate...

Glyphosate activity as affected by spray drop size and leaf coverage

Creator:: King, Wayne O.
Abstract:: Bean shoot parts that respond to glyphosate (N- (phosphonomethyl)glycine) in ways useful for bioassay were determined by applying glyphosate doses of 3.8 to 60.3 ug ae per plant to the simple leaves when the first trifoliolate leaflets were about 1 cm long. Dry weights of parts that were almost fully...

Effects of flooding on peach, apple, quince and several pear species

Creator:: Andersen, Peter C.
Abstract:: A series of experiments was designed to investigate differential flood-tolerance and the phenomenon of flood-induced stomatal closure of several fruit tree species. The first two experiments were conducted with potted plants submerged outdoors 5-10 cm above the soil line. Plant morphology, growth, leaf conductance (cL), and soil oxygen diffusion rate...

A closed root environment for plant production

Creator:: Blackburn, Bryan (Bryan Keith), 1955-
Abstract:: Thesis research focused on: 1) Water and fertilizer gradients within the plant root zone, and effects of chemical and physical gradients on Trichoderma harzianum populations. 2) Regulation of root growth physically with permeable fabric containers and chemically with copper compounds. 3) Effects of copper coatings for fabric containers on Glomus...

Responses of bush snap bean cultivars (Phaseolus vulgaris L.) to plant population densities

Creator:: Stang, Jack Rudolf
Abstract:: The effects of plant population densities on the growth and development of six cultivars of bush snap beans (Phaseolus vulgaris L.) were studied in two field experiments. A systematic planting design was used to achieve a range of densities from 21- to 110 plants per m² and a rectangularity of...

The relationship of electrical impedance to vegetative maturity and dormancy in red-osier dogwood

Creator:: Parmelee, Kathleen Ann
Abstract:: Techniques to measure vegetative maturity and dormancy of deciduous nursery stock were investigated in red-osier dogwood. Previous methods which were based on: survival or tip dieback, change in level of ethylene production, xylem water potential, and alteration of square wave traces traces, provided no better indication of dormancy than did...

Carbohydrate and photosynthate distribution and nitrogen fixation in beans (Phaseolus vulgaris L.)

Creator:: Waters, Luther
Abstract:: A series of four studies were conducted in Colombia, South America, in the field and the greenhouse to determine the effect of plant competition and mulching on carbohydrate and photosynthate distribution and nitrogen fixation in beans (Phaseolus vulgaris L.). Mulching beans (determinant growth habit) with rice hulls in the lowland...

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...
