Plant Growth Regulators (PGRs) and Their Applications: A Review
Journal of Survey in Fisheries SciencesPlant growth regulators (PGRs), also referred to as plant hormones, are chemical substances that profoundly influence various aspects of plant growth and development even at very low concentrations.

Large-scale use of plant growth-regulating chemicals, unheard of ten years ago, has fostered a multimillion dollar business. In 1948, 27 1/2 million pounds of 2,4-D, once used only in minute doses for laboratory work, were manufactured for agricultural use, primarily in weed eradication.

Plant hormones and environmental factors play central roles in the regulation of growth, development, nutrient allocation, and source/sink transitions. The response and adaptation of plants are determined by complex interactions with metabolites, plant growth regulators, secondary messengers, and downstream defense and/or homeostasis genes.

Role of plant growth regulators in improving fruit set, quality and yield of fruit crops: a review
Journal of Horticultural Science & Biotechnology, 2019The plant growth regulators are the organic chemical compounds, other than nutrients and vitamins, which modify or regulate physiological processes in an appreciable measure in the plant when used in small concentration. They are known to influence fruit

2-Naphthyloxyacetic acid (BNOA), having a side-chain 2 carbon atoms long, is highly active in stimulating seedless fruit development in tomatoes. In this paper it is shown that progressive lengthening of the side-chain results in a series of compounds of which only those having an even number of carbon atoms in the side-chain are active.

Castanospermine?a plant growth regulator
Journal of Chemical Ecology, 1988Castanospermine, 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.

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 ...

Plant Science Piezo sensors in animal cells are localized in the cell membrane and transduce mechanical signals. The cell membrane of plant cells, unlike that of animal cells, is usually plastered up against a stiff cell wall and does not have much mobility.
