Delay of anthesis in 'Bartlett' and 'Bosc' pears (Pyrus communis) by evaporative cooling

Creator:: Collins, Margaret Dorothy
Abstract:: The influence of evaporative cooling for delay of 'Bartlett' and 'Bosc' fruit bud development for frost avoidance was investigated. Two mist systems, one in a mature pear orchard and the other in a young pear hedgerow, delayed 'Bartlett' and 'Bosc' bloom up to 15 and 8 days respectively. A low...

The effect of ethylene manipulation on flower bud development of prunus persica and prunus domestica and of pyrus communis ovule senescence

Creator:: Crisosto, Carlos H.
Abstract:: In the Northwest, two tree fruit production problems may be related to the role of ethylene on plant growth and development: flowers and developing fruits are subject to low temperature injury during early spring, and to the low fruit set of 'Comice'. Ethylene may be involved in influencing dormancy and...

Freeze damage of Pinot Noir (Vitis vinifera L.) as affected by bud development, INA-bacteria, and a bacterial inhibitor

Creator:: Gardea, Alfonso A.
Resource Type:: Masters Thesis

Water partitioning and respiration activity of dormant grape buds

Creator:: Gardea, Alfonso A.
Abstract:: Dormancy of 'Pinot Noir' grapevines was characterized. Primary buds required ca 300 cumulative chilling hours (CCH) to initiate the transition from endodormancy to ecodormancy, which occurred in mid November. Additional chilling, up to 1000 CCH, improved budbreak. Changes in bud water content were estimated by gravimetric and spectroscopic methods. Total,...

Influence of canopy orientation on fruiting of 'Ànjou' pears and postharvest urea spray on ovule longevity and fruit set of 'C̀omice' pears

Creator:: Khemira, Habib
Abstract:: The effect of canopy orientation on fruiting performance of 'Beurre d'Anjou' pears (Pyrus communis L.) and postharvest urea spray on ovule longevity and fruit set of 'Doyenne du Comice' pears were studied. Hedgerows of 'Beurre d'Anjou' pear trees planted in 1969 in two orientations north-south (N-S) and east-west (E-W) were...

Water use of cool season grasses and their effect on grapevine (Vitis vinifera) growth and development

Creator:: Doty, Jean A.
Abstract:: The use of grass cover crops is a recommended practice in nonirrigated vineyards in the Willamette Valley, Oregon. Two studies were initiated to investigate the competitive and noncompetitive effects of grass cover crops on the growth and development of Pinot noir grapevines. Two greenhouse pot culture experiments were performed to...

Frost hardiness of buds, flowers and fruit of pear (Pyrus communis L.)

Creator:: Strang, John George
Abstract:: Spring frost damage to pears in the Pacific Northwest frequently results in substantial crop losses. This research was undertaken to investigate the effects of frost on pear buds, flowers, and fruit through controlled freezing tests and field studies in order to better understand the frost phenomenon and refine frost protection...

Effect of several apple rootstocks on growth, yield components and leaf area estimates on "Starkspur Supreme Delicious" trees

Creator:: Siller-Cepeda, Jorge H.
Abstract:: Growth, yield components and leaf area were evaluated on 'Starkspur Supreme Delicious' apple on nine rootstocks: MAC 24, EMLA 7, EMLA 26, OAR 1, MAC 9, 0.3, EMLA 9, M 9, and EMLA 27. Estimates of planting density based on growth, estimates of leaf area based on four independent variables...

Girdling and shading effects on inflorescence necrosis and rachis composition of pinot noir grapevine

Creator:: Ibacache, Antonio E.
Abstract:: There are several grape disorders that reduce fruit set. One, millerandage, is from poor fertilization to produce "hen and chicken" or small seedless berries; while another, Coulure, is the failure of grape flowers to develop into berries. A third one, inflorescence necrosis (INec), is a disorder that should be in...
