Effects of irrigation and nitrogen on cauliflower development, yield and quality

Creator:: Bratsch, Anthony D.
Abstract:: Field experiments were conducted with cauliflower (Brassica oleracea var. botrytis cv. Snowball Y ) to determine crop development, yield, quality and maturity response to various seasonal water levels, and to specific water stress timing in relation to curd initiation. The effects of nitrogen rate, timing, and source and the application...

Somatic manipulation of Pyrus and Cydonia : characterization and selection for iron efficiency

Creator:: Dolcet-Sanjuan, Ramon J.
Abstract:: Appropriate micropropagation regimes were developed for four Pyrus species (P. amygdaliformis Vill., P. betulaefolia Bunge, P. calleryana Dcne., and P. communis L.) and Cydonia oblonga L. Shoot multiplication was optimal at 10 or 20μM N⁶⁻ benzyladenine (BA) and high light intensity (135μm⁻²s⁻1). Root formation of the Pyrus species was stimulated...

Spectroscopy of biophysical, physiological and pathological responses of plant germplasm

Creator:: Li, Ning
Abstract:: Imaging spectra of plant tissues yield considerable potential and useful information for basic studies and agriculture practice. We constructed an imaging spectrophotometer with spectral range from 400 nm to 1100 nm, which was used to study various physiological events of plant germplasm: location of bundle sheath and mesophyll cells in...

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...

Influence of vine vigor and shading in Pinot noir (Vitis vinifera L.) on the concentration and composition of phenolic compounds in grapes and wine

Creator:: Cortell, Jessica M.
Abstract:: In 2003 and 2004 vigor zones were delineated in two commercial vineyard sites based on vine growth variation to assess fruit and wine phenolic chemistry. In 2004, the effects of shading on the accumulation of phenolic compounds were also investigated. Model extractions were done from the shading experiment and the...

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...

Enhancement of the weed competitive ability of lowland rice (Oryza sativa L.) cultivars

Creator:: Ranasinghe, Lakshman L.
Abstract:: Most of the presently grown cultivars of rice (Oryza sativa L.) have poor competitive ability against weeds if compared with traditional cultivars. Therefore, effective weed control is an important but often costly and difficult management practice in rice crop production. If weed competitive ability of rice cultivars could be improved...
