Use of nondestructive spectroscopy to assess chlorophyll and nitrogen in fresh leaves

Creator:: Ding, Pinghai
Abstract:: Four aspects of factors influencing the accuracy of nondestructive chlorophyll (Chl) and nitrogen (N) measurement in fresh leaves were studied: (1) optimum wavelength (OW) identification; (2) indices development and evaluation; (3) influence of leaf properties; and (4) influence of meter parameters and sampling technique. Results were used to develop indices...

Hardiness-maturity relations in red-osier dogwood (Cornus stolonifera Michx.)

Creator:: Nissila, Peter Carl
Abstract:: Red-osier dogwood plants were grown outdoors in a lathhouse and under two temperature regimes in growth chambers to determine the time of vegetative maturity, the transition between summer and winter dormancy. Xylem water potential (XWP), tissue moisture content, ethylene and ethane production, and electrical impedance were used to try to...

Water relations, stomatal conductance, and abscisic acid content of container-grown apple (Malus domestica Borkh.) plants in response to sorbitol-induced osmotic stress

Creator:: Guak, Sunghee
Abstract:: Sorbitol-induced osmotic stress (SIOS) to the root was found to be effective in reducing transpirational water loss in plants during water stress. Mechanisms of SIOS in stomatal control were investigated in containerized apples (Malus domestica Borkh. 'Gala'/M26) when leaf water potential (Ψw), osmotic potential (Ψs), turgor potential (Ψp), stomatal conductance...

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...

The role of glutathione in the development and release of rest on 'Redhaven' peaches

Creator:: Siller-Cepeda, Jorge H.
Abstract:: A rapid and sensitive HPLC method for quantifying both the reduced and oxidized forms of glutathione simultaneously in woody plant tissues was developed. This method was applicable to a variety of woody plant species and different tissues. Total glutathione content in the bark tissue of seven of the woody plant...

Indicators of deciduous shade tree development useful for timing chemical defoliation and harvest

Creator:: Hotze, Mary Louise
Abstract:: In the mild climate of the Pacific Northwest, the harvesting of deciduous shade trees in wholesale nurseries is prolonged from October to January because of autumn growth and prolonged leaf retention. Economically, it is advantageous to defoliate nursery trees at the earliest possible date. Premature defoliation, however, can cause die...

Nitrogen, defoliation and new growth in almond (Prunus dulcis (Mill) D.A. Webb) nursery plants

Creator:: Bi, Guihong
Abstract:: The relationships between nitrogen (N), defoliation, and plant growth in nursery plants were studied using almond {Prunus dulcis (Mill) D. A. Webb) trees. In several experiments the effects of N source and availability on tree growth, N uptake, N remobilization, and nonstructural carbohydrates (TNC) were investigated to determine the most...
