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...

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...

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...

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...

Factors affecting the incidence and severity of Phytophthora syringae cankers in pear (Pyrus communis) trees

Creator:: Laywisadkul, Srisangwan
Abstract:: Container grown pear trees were used to determine the effects of the following factors on the susceptibility to Phytophthora syringae: 1) tree nitrogen (N) status and foliar sprays of urea and copper-EDTA (CuEDTA); 2) dormancy and environmental conditions; 3) wound and wound age; and 4) chemical and biological control measures....

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...

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...

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...
