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...

Relationships between endogenous phenolic compounds of rhododendron tissues and organs and cold hardiness development

Creator:: Chalker-Scott, Linda
Abstract:: The leaching of water soluble phenolic compounds from cold stressed Rhododendron leaves was found to be a reliable indicator of tissue damage. In sublethally stressed leaf tissues, more and novel phenolic compounds appeared and were hypothesized to be precursors of cell wall components such as lignin and suberin. Subsequent radiolabeling...

Characteristics of ice nucleation in potato leaves

Creator:: Johnson, Lori K.
Abstract:: The innate ability of potato leaf tissue to initiate freezing was studied. Two potato species, the non-hardy cultivated potato Solanum tuberosum L. cv. Russet Burbank, and Solanum acaule Bitt. a hardy species from South America, were studied. Two treatments, low (cold) and high (warm) temperatures were included to study the...

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...

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...

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...

Relationship of "near-lethal" stress on dormancy, cold hardiness and recovery of Red-Osier dogwood

Creator:: Shirazi, Abbas M.
Abstract:: The effects of overcoming rest by application of "near-lethal" (NL) stress treatments on the subsequent development of cold hardiness of stem tissues of red-osier dogwood, Comus sericea L., at different rest stages under three post-environments (0°, 23°, and natural condition) were studied. NL-heat stress (47°C for one hour) treatment during...

Modeling of dormancy and cold hardiness in red-osier dogwood (Cornus sericea L.)

Creator:: Kobayashi, Kent
Abstract:: Effects of temperature and growth stage on vegetative bud development and stem hardiness of red-osier dogwood during winter dormancy were investigated. Results were related to a degree growth stage model and were used to develop models to predict growth stages, to quantify development, and to predict hardiness. Maximum rest development...

The free radical scavenging system in overcoming phytotoxicity and breaking dormancy

Creator:: Zhen, Liping
Abstract:: Hydrogen cyanamide (CY) induced earlier budbreak, more uniform and a higher percentage of budbreak in resting poplar (Populus alba x P. gradidentata, NC 5339) plants. However, it was phytotoxic to poplar when applied at 0.5 M or higher concentrations. Percent budbreak increased and percent dieback decreased when poplar plants were...
