Physiological and cultural conditions affecting postharvest handling of bare-root nursery plants

Creator:: Englert, John M.
Abstract:: Nursery plants are often harvested, stored, and shipped bare-root for easier and more economical handling. Some species of woody and herbaceous perennials are less tolerant of postharvest handling than others. Desiccation stress during the handling of bare-root plants has been identified as a major problem contributing to poor survival and...

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 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...

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...

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....

Overexpression of antioxidant genes in transgenic tomato tolerant against multiple stresses

Creator:: Wang, Yueju
Abstract:: The effect of increased manganese superoxide dismutase (Mn-SOD) and cytosolic ascorbate peroxidase (cAPX) on various abiotic stresses was studied using transgenic tomato (Lycopersicon esculentum) plants. Transformants were selected in vitro based on kanamycin resistance, confirmed by PCR and northern blot analyses. Northern blots showed an enhanced gene expression of Mn-SOD...

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...

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...
