“…Limpanavech et al demonstrated that chitosan could increase the chloroplast diameter of the Dendrobium orchid through affecting chloroplast gene expression, especially when its concentration was 10–50 ppm. According to Cuero et al, rapid uptake of N -carboxymethylchitosan (NCMC) could increase the chlorophyll content in leaves of NCMC-treated tomato plants under greenhouse conditions; the process is probably mediated by modification of nutrient levels in plant tissues. In contrast to macropolymers, nanoparticles may help in the quenching of oxygen free radicals from the photosynthetic process and improve the photosynthetic rate .…”

This study investigated the effects of different rates of nanochitin in soil on the grain yield and quality of winter wheat. Nanochitin obtained by acidic hydrolysis of shrimp chitin was a rod-like whisker possessing a hydrodynamic diameter of 143 nm and ζ potential of 55.7 mV. Two varieties of winter wheat, multi-spike wheat (MSW) and large spike wheat (LSW), were treated with the nanochitin suspension in outside pot experiments. The results showed that 0.006 g kg of nanochitin in soil could significantly enhance the yield by 23.0% for MSW and 33.4% for LSW, with significant increases of net photosynthesis rate, stomatal conductance, intercellular CO concentrations, and transpiration rate in flag leaf at the grain filling stage. Grain protein, iron, and zinc contents in wheat treated with nanochitin were also increased by 5.0, 10.3, and 22.1% for MSW and 33.4, 32.0, and 27.0% for LSW, respectively. This indicated that utilization of nanochitin has a great potential in future agriculture sustainability and crop production.
