Seasonal and short-term nitrogen cycling in Populus

Creator:: Black, Brent L.
Abstract:: Poplar Bark Storage Proteins (BSP) are important in storing nitrogen (N) recovered from autumn-senescent leaves, and supply N for spring growth. Plants of Populus tremula x P. alba were transformed with a poplar BSP antisense cDNA fused to a double 35S promoter. Regenerated lines were screened for reduced BSP accumulation...

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...

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...

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...

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...

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....

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...

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...
