ROOT PRODUCTION AND THE ESTIMATION OF NET PRODUCTIVITY

Canadian Journal of Botany, 1963
Data on the net production of oven-dry organic matter from 28 temperate angiosperm herbaceous species and 4 temperate arboreal species were analyzed to determine the relationship between below-ground and above-ground yearly increment. Mean yearly net herbaceous production (t/ha) was 3.9 for below-ground parts, 5.9 for above-ground parts, and 9.8 total.

Grass roots productivity: productivity managed by the productive.

Radiology management, 1986
Can there be a radiology productivity system that enlists the eager support of technologists and is endorsed by management? Can there be a productivity system that involves 10-15 minutes of time per day to manage and produces meaningful results? Can there be a productivity system that is run by employees?

Large-Scale Production of Hairy Root

2004
Many products of interest are synthesized in organized tissues, but not formed in suspension or callus culture. Therefore, most attention has been focused on root cultures. The transgenic plant,"hairy root", has brought us to dramatic improvements in growth rate and high content of desirable products.

Fine Root Production and Demography

1999
Abstract Attributes of root systems appear to have resulted from pressures on plants to maximize the efficiency of soil resource acquisition and to cminimize the risk of injury or death at environmental or competitive extremes (Yanai et al. 1994).

Production of Phytoalexin in PEA Roots

1989
Abstract Pea was used as a model plant to investigate the capacity of roots for production of phytoalexin pisatin and the degree of its release into the environment from roots. The rate of pisatin production can be determined as the amount released into hydroponic solution during 24 h.

Thiarubrine production in roots and root cultures of Ambrosia chamissonis

2008
Ambrosia chamissonis (Asteraceae) provides antibiotic sulphur heterocyclic polyynes known as thiarubrines and thiophenes. They occur in all parts of the plant, especially in the roots and can be visualized in hand sections. Methods were developed for their isolation, purification and quantification.

n!, ROOTS, LIMITS, AND PRODUCTS

PRIMUS, 1993
ABSTRACT This paper is meant to offer Calculus teachers and students an occasion to ask some questions and look for connections between several ideas. When faced with the problem of finding an unusual limit, such as limn→∞ , one might need to employ unusual techniques. While the recourse to these techniques might increase the chance of making mistakes,
