“…Chitosan can increase plant growth and development under normal conditions and water deficit, positively changing several characteristics. The application of the biopolymer led to an increase in plant height, number of shoot branches, number of leaves, leaf area, biomass attributes and grain yield in several plant species such as maize (Guan et al 2009;Lizárraga-Paulín et al 2011;Mondal et al 2013;Martins et al 2018), beans (Ibrahim and Ramadan 2015), soybeans (Lee and Chung 2005), wheat (Wang et al 2015), rice (Boonlertnirun et al 2007;Pongprayoon et al 2013;Chamnanmanoontham et al 2015), millet (Sharathchandra et al 2004), coffee (Dzung et al 2011), among others. There is still little research on the use of these biopolymers in the stimulation of physiological responses to water stress tolerance.…”

Chitosan induces plant tolerance to various abiotic stresses, including water deficit. However, its use may be limited, due to its constitution and low solubility in water. Thus, chemical modifications were proposed in this study with the objective of potentializing its biological effects in maize plants. The derivatives were semi-synthesized (N-succinyl and N,O-dicarboxymethyl) and, together with chitosan, they were applied, via the leaf, in a drought-sensitive maize hybrid (BRS1030) under pre-flowering water deficit. The water deficit was maintained for 15 days and the analyses were performed at the beginning and end of stress, and also in rehydration. Leaf water potential, gas exchange, chlorophyll fluorescence, and content of chloroplastidic pigments were evaluated. The use of the derivatives modulated photosynthesis parameters, affecting the involved mechanisms, such as stomatal activity, water use efficiency and photosystem II activity. Chlorophyll fluorescence indicated that the antenna complex was damaged by the water deficit condition, with a decrease in the energy flux in the electron transport chain and in the photochemical phase of photosynthesis. However, the spraying of chitosan derivatives induced tolerance to water deficit, suggesting that chitosan derivatives are more bioavailable to plants. Water stress decreases pigment content, but both the application of chitosan and derivatives increased these contents. It is concluded that chitosan derivatives improved the photosynthetic parameters in maize susceptible to drought, inducing tolerance to this stress, and the possible reasons and consequences are discussed.

Iron chlorosis represents a physiological phenomenon with negative impact on the quality and quantity of grape production in the vineyards. The bicarbonates are considered to be the main group of compounds which immobilize the iron in the soil in forms not assimilable by the plants. The grape production in conditions of iron deficiency can be improved significantly by applying foliar fertilizers. The best result in mitigating the effects of iron deficiency were obtained by the application of the fertilizers which, in addition to a complex mineral composition, also have a content of organic matter in the form of humic substances or protein hydrolysate.

“…It is obtained from the outer shell of crustaceans such as crabs and shrimps. It has been reported as a high potential bio-molecule that increases abiotic stress tolerance, induce pathogen resistance, plant growth and yield (Ibrahim and Ramadan, 2015). That has been used to improve vegetative growth and performance of tomato plants (Dawa et al, 2017).…”

This experiment was conducted during the summer seasons of 2015 and 2016 to investigate the effect of various water irrigation levels (60%, 80% and 100% from ET o ) and some foliar application treatments (chitosan, salicylic acid, silicon and proline) and their interactions on vegetative growth characteristics and leaf chemical constituents of tomato plants (Solanum lycopersicum L) " Fayruz " hybrid under surface drip irrigation system in a private farm at Gemiana village near El-Mansoura city, Dakahlia Government, Egypt. All treatments under investigation significantly affected vegetative growth parameters, i.e., plant height, number of branches, number of leaves, leaf area, fresh and dry weights, as well as chemical constituents of leaves as photosynthetic pigments (Chl. a, Chl. b and total Chl. a+b), leaf minerals content (N, P and K), proline and peroxidase activity. Results indicated that the highest values of all aforementioned parameters except proline and peroxidase were recorded when plants irrigated with 80% from ET O compare to 60% and 100 from ET O in both season of study, while the highest values of proline and peroxidase activity were recorded with 60% from ET O . All foliar applications treatments significantly increased vegetative growth traits, leaf mineral and pigments content compared to control (without foliar spray) which recorded the highest values of proline content and peroxidase activity. Foliar application of chitosan at 500 ppm was the most effective treatment on all aforementioned parameters followed with SA at 100 ppm. Concerning the interaction effect among water irrigation levels and foliar application treatments, the best result of all studied parameters were recorded when plants irrigated with 80% from ET O and sprayed with chitosan at 500 ppm. Therefore, this treatment could be recommended to increase tomato plant growth and improve its performance.
