Abstract:: Hereditary variation is a vital component in the development of new and improved cultivars of landscape plants. Sources of hereditary variation include naturally occurring variation, recombination due to controlled crosses, artificial mutagenesis, and genetic modification via biotechnology. Here I explore all methods with the exception of genetic modification via biotechnology....

Abstract:: When wheat is exposed to rain in the period before harvest, it sometimes causes the problem of pre-harvest sprouting (PHS). Wheat that undergoes sprouting has poor end-use quality and is less valuable. In recent years, the U. S. Pacific Northwest (PNW) has experienced increased summer showers sometimes causing widespread PHS....

Abstract:: Various soil tests are routinely used in the United States to predict soil lime requirement. New non-hazardous methods have recently been proposed for adoption in Oregon, however the accuracy of these methods for Oregon soils has not been established. The objectives of this investigation were: (a) to document and describe...

Creator:: Skillin, Paul H.
Abstract:: Cannabis sativa L. is emerging as an economically important crop, particularly for its high levels of cannabinoid production. One of these cannabinoids, cannabigerolic acid (CBGA), is the precursor to many well-researched cannabinoids such as the psychotropic delta-9-trans-tetrahydrocannabinolic acid (Δ9-THCA i.e., THCA) and the medically relevant cannabidiolic acid (CBDA). CBGA has...
