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...

Acclimatization of in vitro apple and plum trees to low relative humidity

Creator:: Brainerd, Kim Ethel
Abstract:: Acclimatization of in vitro apples and plums was examined in four studies: l) Leaf anatomy and water stress of aseptically cultured 'Pixy' plum grown under different environments, 2) Acclimatization of aseptically cultured 'Mac 9' apples to low relative humidity, 3) Stomatal functioning of aseptically cultured 'Mac 9' apple leaves in...

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...

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....

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...

Strategies for machine harvesting of mature coffee (Coffea arabica L.) fruits

Creator:: Tongumpai, Peeradet
Abstract:: Greenhouse and field grown coffee plants were used to study the synchronization of flowering and fruiting. The purpose of these studies was to develop methods of improving the selective harvesting of mature coffee fruits by machine. The studies were divided into 4 parts: 1) Synchronization of flowering, 2) Synchronization of...

Growth in herbaceous perennials

Creator:: Nakajima, Rie
Abstract:: Several studies of herbaceous perennials have addressed the effects of environmental factors during and after production, inherent cold hardiness, and post-harvest handling procedures to enhance flowering and growth during establishment. The regrowth of both woody and herbaceous forage plants following establishment is reported to be directly related to reserve-nitrogen content....

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...
