For a long time, morphological observations, microscopes, and simple chemical analyses were fruit tree researchers’ major tools. However, then, toward the middle of the 20th century, horticulturists were enchanted by the plant hormone concept. The
On 18 July 2004, a workshop was held at the ASHS Annual Meeting in Austin, TX, for the purpose of considering the different dimensions of a growing problem that commercial nurserymen in North America are having in controlling strawberry plant
Pineapple lily, a recent introduction to the potted crop market, grows from a true bulb forming a rosette of lanceolate leaves. From that rosette emerges a spike inflorescence lined with star-shaped florets and a terminal tuft of bracts making it

applications should slow development of P. xanthii resistance to fungicides. We initially screened 100 watermelon plant introduction (PI) accessions for resistance to watermelon race 1W of P. xanthii ( Davis et al., 2001 ). This led to the release of

Abstract
Nine dwarf seedlings among 34 arose from interspecific hybridization between Camellia sasanqua Thunb (Plant Introduction 319285) and C. oleifera Abel (Plant Introduction 162561). One dwarf plant flowered and appears to have potential horticultural value.
. Understanding the molecular basis for urushiol biosynthesis and urushiol chemical ecology will require a variety of molecular genetic methods, all of which require the introduction and expression of recombinant DNA in poison ivy plant cells and tissues. The
2022, blue honeysuckle was added to the Species Watch List for Maine, which includes plants that could become invasive but do not presently meet all the criteria for inclusion on the state’s list of plants prohibited from sale or import (Maine
