When I was a sophomore at Big Sandy High School, we started a new club: speech and debate. I liked it better than any other extracurricular activity because it was easy to make friends with people from all over the state. In sports, you shook hands with the other team after the game, but you didn’t really mix with them much—the objective was to beat ...

1977
Our interest in this subject arose from the discovery (43) of the selective herbicides, 3,5-diiodo-4-hydroxybenzonitrile (ioxynil) and the dibromo derivative (bromoxynil), both of which are widely used in agriculture. This discovery stimulated research on their mode of action and metabolism, and investigations on chemical structure in relation to ...

Simulating root growth dynamics
Environmental Software, 1996Abstract We present a simple root-growth model that is capable of reproducing root distribution patterns as conditioned by varying soil conditions. The model assumes that the lateral growth of roots at any depth is governed by two factors: (i) the current root mass or root-length density at a given depth, and (ii) an environmental factor that may ...

Botanical Gazette, 1967
Horizontally growing root tips from red maple trees (Acer rubrum L.), when grown through a holder and then deflected laterally by a barrier, curve back toward their original direction as they grow beyond the barrier. The amount of recurvature increases as the angle of the barrier is increased up to a barrier angle of 60⚬ but decreases only slightly as ...

Plants represent a significant part of our natural environment and their detailed study becomes more and more interesting (also economically) because of their importance for mankind as a source of food and/or energy. One of the most characteristic biological processes in plant life is their growth; it serves as a good indicator for the compatibility of

Plant and Soil, 1987
A model is developed for the rate of elongation of a root tip in terms of the balance of pressures acting on the root. Differentials of this equation give expressions for the changes in root elongation rate with respect to soil water potential and soil mechanical resistance.

Annual Review of Plant Physiology, 1953
The following review deals with the growth of roots in a fairly broad sense. It has been possible in a few instances only to separate from each other experimentally the different kinds of growth, i.e., cell multiplication and cell elongation. Usually growth as measured by length, weight or, less frequently, by volume of roots denotes the sum of an ...
