Study of seed germination-associated genes using Arabidopsis enhancer-trap

Creator:: Liu, Po-Pu
Abstract:: In mature Arabidopsis seeds, the testa (seed coat) is no longer a living tissue. Thus, major sites of gene expression in imbibed seeds are the internal living tissues such as the embryo and the endosperm. To elucidate the molecular mechanisms of seed germination, the gene regulation in these two tissues...

Effect of crop load on mineral uptake and partitioning in D'Anjou pears

Creator:: Meddouri, Messaoud
Abstract:: Three thinning levels were applied to twenty-five-year-old D'Anjou pear trees in a completely randomized design with five single-tree replicates on June 2, 1985. Samples of wood, shoot leaves, shoot twigs, spur leaves, spur twigs and fruits were taken every month during the season of growth for mineral analysis. Sampling an...

Inflorescence necrosis, ammonium, and evidence for ferredoxin-glutamate synthase activity in grape (Vitis vinifera L.)

Creator:: Creasy, Glen L.
Abstract:: Death of flower parts near bloom due to inflorescence necrosis (IN) is associated with high ammonium (NH₄⁺) concentration in flower clusters, shade, cool wet weather preceding bloom, and excessive vigor. Faults in NH₄⁺ assimilation are suspected to cause a rise in NH₄⁺ concentration to toxic levels in flower cluster but...

Inheritance of resistance to the lentil strain of pea seedborne mosaic virus in Pisum sativum L.

Creator:: Kasimor, Kathryn T.
Abstract:: The inheritance mode of pea-resistance to the Lentil Strain of Pea Seedborne Mosaic Virus (PSbMV-L) was studied. In addition, commercial pea cultivars, Plant Introduction (P.I.) lines and Oregon State University (OSU) breeding lines were tested for susceptibility to this virus. These lines were also tested for their reaction to Bean...

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...

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...

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...

Fruit color development in red pears

Creator:: Dussi Dehais, Maria Claudi
Abstract:: A fruit color descriptive study was conducted on 'Max' and 'Sensation' Red Bartlett, 'Columbia' and 'Gebhard' Red Anjou, 'Rogue Red', 'Rosired', 'Red Clapp' and 'Cascade' red pear varieties. A parallel comparative study was done to test differences between related red strains. 'Max' was compared with 'Sensation' in three different growing...
