Relationship of boron to reproduction in hazelnut (Corylus avellana L.)

Creator:: Shrestha, Gyan Kumar
Abstract:: Boron sprays produced fruit set increases in 'Barcelona' hazelnut orchards in 1984 and in 1985. The absolute fruit set was correlated with leaf B content but not with nut B. With relative fruit set (RFS), B content of nuts in May (r = 0.63**) was more strongly related to set...

Interaction between hazelnut (Corylus avellana L.) shoot development and big bud mite (Phytoptus avellanae Nal. and Cecidophyopsis vermiformis Nal.)

Creator:: Burgess, Jean E.
Abstract:: The influence of environmental and genetic variation in plant morphology and development on eriophyoid bud mite (Phytoptus avellanae Nal. and Cecidophyopsis vermiformis Nal.) behavior, survival and colonization on Corylus avellana L. was studied. The distribution pattern of galled buds was consistent with the observation that mites colonize only those buds...

Overexpression of antioxidant genes in transgenic tomato tolerant against multiple stresses

Creator:: Wang, Yueju
Abstract:: The effect of increased manganese superoxide dismutase (Mn-SOD) and cytosolic ascorbate peroxidase (cAPX) on various abiotic stresses was studied using transgenic tomato (Lycopersicon esculentum) plants. Transformants were selected in vitro based on kanamycin resistance, confirmed by PCR and northern blot analyses. Northern blots showed an enhanced gene expression of Mn-SOD...

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...

Annual bluegrass (Poa annua L.) control with ethofumesate during turfgrass establishment

Creator:: Wieneche, David L.
Abstract:: Temperate climates are particularly conducive to growth of annual bluegrass which readily invades and dominates most cool-season turfgrasses. Ethofumesate (2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate) is one herbicide available which will selectively control annual bluegrass. The primary objectives of this research were to determine optimum application rates and timing of ethofumesate for control of...

Eastern filbert blight in hazelnut (Corylus avellana): identification of new resistance sources and high resolution genetic and physical mapping of a resistance gene

Creator:: Sathuvalli, Vidyasagar R.
Abstract:: European hazelnut, Corylus avellana L., is the only economically important nut crop in the family Betulaceae. One of the threats to the hazelnut industry in the Pacific Northwest is the fungal disease eastern filbert blight (EFB) caused by the pyrenomycete Anisogramma anomala. Host genetic resistance to EFB identified in the...

Fine Mapping and Gene Expression Analysis of Self-Incompatibility in Hazelnut

Creator:: Hill, Ryan J.
Abstract:: The European hazelnut (Corylus avellana L.) is a diploid (2n = 2x = 22) tree crop important to the economy of Oregon’s Willamette Valley, where 99% of hazelnut production in the United States is located. Corylus avellana exhibits sporophytic self-incompatibility (SSI), controlled by a single S-locus with at least 33...

Imaging fluorescent determination of energetics of chloroplast division and related matters

Creator:: Zheng, Ping
Abstract:: During exploration of imaging photosynthetic fluorimetry of Arabidopsis thaliana mutants, we discovered a novel phenomenon wherein photosynthetic efficiency (defined in Ning et al., 1995) is shown to plot in discrete groups. This exploration resulted first in the development of a spectrofluorometric method that apparently allows for in vivo observation of...

Determination of α-Amylase activity and soluble starch content in normal and cork spotted D̀'Anjou' pear fruit

Creator:: Li, Shiao Jing
Abstract:: There was a linear relationship of [alpha]-amylase activity from 2 to 12 hours incubation in both freeze-dried and fresh 'd'Anjou' pear fruit tissue. Activity was greater, however, in fresh as compared with freeze-dried tissues. [alpha]-Amylase activity from both types of samples was not detected until 60 minutes incubation. After 90...
