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...

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...

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...

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 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...

Water relations and the root regeneration response of Douglas-fir

Creator:: Cobb, Cheryl Anne
Abstract:: The effect of lifting date and root-pruning treatments on water potential, root regeneration, and shoot growth of six-month-old and three-year-old Douglas-fir seedlings bare-root transplanted into a growth chamber, and sawdust bed, respectively, was studied. Root growth in six-month-old and three-year-old seedlings was highest in February and August respectively. Survival was...

Hydrogen cyanamide on triphenyltetrazolium chloride reduction, sulfhydryl group binding, and catalase activity in bromegrass (Bromus inermis Leyss) cells

Creator:: Zhen, Liping
Abstract:: Hydrogen cyanamide (CY) has been used to break rest in temperate crops, but levels used to overcome rest are sometimes toxic to plants. The rest breaking effect of CY is thought to involve peroxide metabolism. Inhibition of catalase by CY has been proposed as a mechanism for overcoming dormancy in...

Physiology of flowering in Coffea arabica L. : role of growth regulators and water relations

Creator:: Schuch, Ursula K.
Abstract:: Coffee trees growing in the Kona district of Hawaii were treated with different concentrations of either BA, GA3, or Promalin, and pruned at the time of flowering. No significant differences in the flowering and fruit ripening pattern were found. High concentrations (100 mg/1) of growth regulators decreased fruit fresh weight....
