Harmful Garden Plants In Western Australia, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

Many garden plants can cause harm. Some are commercially available and very popular; others are no longer readily available but still exist in older gardens; and yet others are favourite indoor ornamentals, cut-flowers, weeds, or even fruit and vegetables that we consume frequently, often without realising that other parts of those same plants are harmful.

It is impractical and unnecessary to remove from our gardens every single plant that could conceivably be harmful. A more sensible approach is to be aware of the potential danger of a particular plant, and then assess how much or how little risk it poses …

The Vascular Flora Of Powhatan County, Virginia, Michael Austin Terry

Master's Theses

The project was undertaken with three main goals in mind: to provide as current and complete an account as possible of the flora of Powhatan County in the form of an annotated checklist; to integrate the information obtained from the inventory into phytogeographical and ecological generalizations currently being developed for the state of Virginia; and, to report any significant or anomalous discoveries. There is no previous county-wide inventory of plant diversity for Powhatan County. However, Corcoran (1981) published a list of plants from the Jones and Mill Creek watershed located in the Fine Creek Mills area of northeastern Powhatan.

A New Microsensor System For Plant Root Zone Monitoring, Chang-Soo Kim, Sandeep Sathyan, D. M. Porterfield

Electrical and Computer Engineering Faculty Research & Creative Works

The objective of this work is to develop a new microsensor system that can monitor dissolved oxygen and hydration environment at the plant root zone. A miniaturized plant growth system is prepared including the root zone layer, either a porous ceramic tube or porous ceramic wafer on which the plant is grown, and an underlying fluidic channel to deliver nutrients and water to the root zone. We demonstrate the feasibility of using a flexible microsensor array for dissolved oxygen detection, and a four-electrode impedance microelectrode for wetness detection on the surface of a porous tube nutrient delivery system. The unique …
