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...

Soil temperature suppression on growth and yield of potato (Solanum tuberosum L.) in warm climates of Sri Lanka

Creator:: Tharmarajah, S. K.
Abstract:: Potato (Solanum tuberosum L.) is one of the most productive and nutritious food crops. Due to its adaptability to cool climates, production in Sri Lanka has been restricted to erosion-prone highlands. Vast potential exists for expansion of potato cultivation in the lowlands while production areas in the highlands are limited...

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...
