“…In three studies on orchids it was found that chitosan was effective at a very low concentration of 10 mg L −1 [164][165][166]. This indicates that the chitosan was acting due to mechanisms other than simply improving nitrogen nutrition or as a carbohydrate energy source.…”

“…The reports of chitosan treatments stimulating growth should be tempered by the findings of other trials showing no significant effect on growth, biomass production, or yield in rice and soybean [167], and maize and soybean [168]. Both Pornpeanpakdee et al [165] and Nahar et al [166] found that the growth of orchids (Dendrobium and Cymbidium respectively) was enhanced when chitosan was supplied to micropropagated plants growing under aseptic conditions. These findings show that chitin can promote the growth of plants independently of its actions on plant growth promoting rhizobacteria (PGPR).…”

“…The growth of micropropagated crops has been shown to increase following the inclusion of chitosan to the growth medium [162,165,166,169]. As many of the defensive secondary metabolites activated by chitin elicitation are useful as medicines, or their precursors, the use of soluble chitosan in tissue culture and hairy root culture laboratories to produce medicinal plants with elevated levels of active compounds has been widely studied.…”

Abstract:In recent decades, a greater knowledge of chitin chemistry, and the increased availability of chitin-containing waste materials from the seafood industry, have led to the testing and development of chitin-containing products for a wide variety of applications in the agriculture industry. A number of modes of action have been proposed for how chitin and its derivatives can improve crop yield. In addition to direct effects on plant nutrition and plant growth stimulation, chitin-derived products have also been shown to be toxic to plant pests and pathogens, induce plant defenses and stimulate the growth and activity of beneficial microbes. A repeating theme of the published studies is that chitin-based treatments augment and amplify the action of beneficial chitinolytic microbes. This article reviews the evidence for claims that chitin-based products can improve crop yields and the current understanding of the modes of action with a focus on plant-microbe interactions.

“…Chitosan and hyaluronic acid is well known elicitors; chitosan, obtained primarily from the exoskeleton of crustaceans, but also found in cuticles of insects as in the cell walls of fungi and some algae, is one of the most common polymers that could be found. Chitosan has had a strongly positive effect on many growth responses in a number of plants, including orchids (Kaewjampa et al, 2010;Nahar et al, 2011;Teixeira da Silva, 2013) the mechanism of action remains unknown. Hyaluronic acid (HA), composed of glucuronic acid and N-acetyl glucosamine joined alternately by β-1-3 and β-1-4 glycosidic bonds, has biological functions in lower and higher organisms, including in cell adhesion, migration, proliferation and differentiation, regulation of protein secration and gene expression (reviewed by Fraser et al, 1997).…”

“…HA suppresses disease in cucumber, tomato and pepper (Park et al, 2008) and has shown to have antioxidant activity. HA have of recent been suggested as important components of Cymbidium in vitro culture media (Nahar et al, 2011Nahar and Shimasaki, 2014;Kaewjampa et al, 2012). Therefore, the objective of this study was to investigate the effect of light quality and plant growth regulator on organogenesis of C. dayanum in vitro.…”

The widespread usage and production of microplastics (MPs) products has resulted in a surge of plastic waste in the natural environment. Chitosan (CH) is a natural polymer derived from chitin, found in the shells of crustaceans such as shrimp and crabs and studied extensively for its potential use as an amendment. The dynamic interplay between plastic, specifically polystyrene (PS), and the potential of CH as a soil enhancer holds pivotal implications for soil health and crop vitality. While PS seems to wield minimal influence on soil pH, CH demonstrates a distinct ability to lower pH levels significantly. However, the synergy between CH and PS in altering soil pH is relatively limited. Importantly, CH emerges as a compelling countermeasure against the detrimental impact of PS on soil chemistry. Its application brings about promising changes, such as mitigating nutrient depletion and enhancing organic matter (OM). Shifting focus to crop growth, PS emerges as a growth inhibitor, substantially reducing maize biomass and chlorophyll content. Conversely, CH emerges as a growth stimulant, positively affecting root and shoot dry weights, leaf area, and plant height. The interplay between CH and PS manifests complex outcomes on these growth metrics, indicating interdependence. These findings resonate with sustainable soil management practices and the optimization of crop productivity. Further scrutiny is warranted to unravel the underlying mechanisms and long‐term consequences, offering a comprehensive understanding of the interaction between PS, CH, and the ecological landscape. Such insights pave the way for informed decisions in ecological preservation and agricultural sustenance.
