Plant hormones, plant growth regulators

Orvosi Hetilap, 2014
Plants seem to be rather defenceless, they are unable to do motion, have no nervous system or immune system unlike animals. Besides this, plants do have hormones, though these substances are produced not in glands. In view of their complexity they lagged behind animals, however, plant organisms show large scale integration in their structure and ...

On the action of plant growth regulators

Biochimica et Biophysica Acta, 1952
Abstract A plant growth regulator 2-methyl 4-chlorophenoxy acetic acid “MCPA” is interacted with a range of surface-active compounds, spread as monolayers on a Langmuir trough, to investigate factors involved in its mode of action within the plant. By using quaternary ammonium salt C 18 H 37 N + (CH 3 ) 3 }Cl − , it is deduced that “MCPA” interacts ...

Castanospermine?a plant growth regulator

Journal of Chemical Ecology, 1988
Castanospermine, 1,6,7,8-tetrahydroxyoctahydroindolizine, has been shown to be a potent dicot phytotoxin. The effective concentration to inhibit root length elongation of dicot roots by 50% is 300 ppb, while the effective concentration against monocot roots is 200 ppm, i.e., 10(3) times less effective.

Plant Growth Regulators, Viruses and Plant Growth

1990
Virus infection alters plant growth and development. The role of plant growth regulators (PGRs) in control of these processes in diseased plants is reviewed, taking tobacco mosaic virus infections of tobacco and tomato as the main model systems. Growth inhibition was related primarily to severity of visible mosaic symptoms rather than to the extent of ...

Cytokinins in Regulation of Plant Growth

1973
The extension of principles governing gene-controlled protein biosynthesis in prokaryotes as a basic regulatory mechanism common to all growth and developmental processes in eukaryotes, also, is now generally accepted. The question, then, is, what factors are involved in modulating the expression of genetic potentials in cells with an identical genome ...

Plant Growth Regulators

2016
This chapter reviews the use of plant growth regulator for fresh vegetable and fruit quality. Endogenous plant growth regulators, also named phytohormones, are important regulator of many functions in plant development and physiology. First, this chapter describes the five major classes of PGR (auxins, gibberellins, cytokinins, abscisic acid, and ...
