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...
Five nutritional aspects of 'Valencia' orange production in Agadir, Morocco
during 1989-1991 were evaluated: 1) the effect of N and K on yield and fruit
quality, 2) leaf sampling time and diagnostic approaches to optimize mineral
nutrition, 3) mass and mineral partitioning within individual trees, 4) K-Rb
relationships, and 5)...
Recent concern over the potential environmental impact of highway construction
and repair materials on surface and ground waters has lead to extensive laboratory
screening and subsequent testing of a set of new materials and waste amended mixes. As
part of Phase II of a three-phase project for the National Cooperative...
Attempts to develop dual-purpose durum wheat cultivars for both pasta and bread-making
have been unsuccessful. To better understand this limitation, thirty durum
genotypes, selected based on their diverse geographical origin, and five bread wheat
cultivars were compared as to their flour mixing properties, dough physical characteristics
and baking performance. The...
There is a software gap in parallel processing. The short lifespan and small installation base of parallel architectures have made it economically infeasible to develop platform-specific parallel programming environments that deliver performance and programmability. One obvious solution is to build architecture-independent programming environments. But the architecture independence usually comes at...
The feasibility of managing codling moth, Cydia pomonella (L.), with mixtures
of Bacillus thuringiensis-based microbial and selected chemical insecticides was
studied under laboratory and field conditions. Joint actions (synergism, additivity and
antagonism) of these mixtures were determined for both egg and larval stages. Higher
rates of microbial control agents (MCAs),...
