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...

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...

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...

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...

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...

Relationships of ammonium and nitrate status with inflorescence necrosis in 'Pinot noir' grapevines

Creator:: Gu, Sanliang
Abstract:: Inflorescence necrosis (IN) is a recently described disorder in grapes characterized by partial or complete deterioration of the pedicel and rachis near bloom. Elevated levels of ammonium in the rachis are associated with the incidence of IN and hypothesized as the cause of the disorder. An incubation system with single-node...

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...
