Assessing the impact of garden education programs on motivational engagement and academic achievement

Creator:: Gupta, Abha
Abstract:: School garden programs have become increasingly popular for their diverse, positive benefits. School gardens are often promoted as a relatively low cost means to offer hands-on learning opportunities that may foster academic achievement, particularly in the sciences, however only six studies have been published on the impact of garden education...

Evaluating the Attractiveness of Pacific Northwest Native Plants to Insects and Gardeners

Creator:: Anderson, Aaron G.
Abstract:: Due to a growing body of literature documenting declines in pollinator populations, there has been increased public interest in pollinator conservation. In urban and suburban landscapes, many gardeners and urban land managers are interested in gardening for pollinators, particularly bees. Simultaneously, many homeowners and municipalities are interested in other aspects...

Characterization of geohumus for use in turf

Creator:: Patton, Ty J.
Abstract:: Geohumus is a new, unique hybrid soil amendment made of polyacrylic acid, igneous rock flour, and quartz sand. It is biodegradable and is marketed to increase soil porosity, increase plant yield, and increase plant available water by up to 30%, all while using a low inclusion rate of only 1...

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...

Diagnostic approaches to evaluate nutrient status, partitioning, mineral dynamics, and relationships with yield and fruit quality of 'Valencia' orange trees

Creator:: Tami, Mohamed
Abstract:: 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)...

Water relations, stomatal conductance, and abscisic acid content of container-grown apple (Malus domestica Borkh.) plants in response to sorbitol-induced osmotic stress

Creator:: Guak, Sunghee
Abstract:: Sorbitol-induced osmotic stress (SIOS) to the root was found to be effective in reducing transpirational water loss in plants during water stress. Mechanisms of SIOS in stomatal control were investigated in containerized apples (Malus domestica Borkh. 'Gala'/M26) when leaf water potential (Ψw), osmotic potential (Ψs), turgor potential (Ψp), stomatal conductance...

Traditional and molecular approaches to Zucchini yellow mosaic virus resistance in Cucurbita

Creator:: Brown, Rebecca Nelson
Abstract:: Zucchini yellow mosaic virus (ZYMV) is an important disease of Cucurbita worldwide. Resistant cultivars are the best means of control. ZYMV resistance is quantitative in the wild species C. ecuadorensis, and is controlled by at least three genes in tropical C moschata. Very little molecular work has been done in...

The translocation of ethephon and its physiological effects on the filbert (Corylus avellena L.) during husk senescence

Creator:: Kwong, Francis Y.
Abstract:: Nut drop in the filbert is a consequence of the senescence of the husk. It is possible to accelerate this process by the application of ethephon (2-chloroethyl)phosphonic acid after the nut has abscised from the base of the husk. This study is an investigation on the physiological effects of the...

Effects of flooding on peach, apple, quince and several pear species

Creator:: Andersen, Peter C.
Abstract:: A series of experiments was designed to investigate differential flood-tolerance and the phenomenon of flood-induced stomatal closure of several fruit tree species. The first two experiments were conducted with potted plants submerged outdoors 5-10 cm above the soil line. Plant morphology, growth, leaf conductance (cL), and soil oxygen diffusion rate...
