Morphological changes and antioxidative capacity of jute (Corchorus capsularis, Malvaceae) under different color light-emitting diodes

Abstract

Light quality is an important environmental factor controlling plant growth and development. On the other hand, jute (Corchorus capsularis L.) (jute) is sensitive to light quality and the factory production of C. capsularis for vegetable use and for transplanting in the field requires an investigation of the responses of C. capsularis to light quality. For this purpose, a pot experiment was conducted to investigate the effect of different color light-emitting diodes (LED) on growth, chlorophyll contents, reactive oxygen species (ROS) production and antioxidative defense system in C. capsularis under glasshouse environment. Different light-emitting diodes were used in this study: white light (WL), red light (RL), dark red light (DL), mixed dark red light (ML), blue light (BL) and orange light (OL). Results showed that RL, DL and ML significantly (P ≤ 0.05) increased plant height, crown length and plant biomass as compared with control (WL). All red-light spectrum, i.e., RL, DL and ML, improved leaf development, but decreased malondialdehyde (MDA) and proline contents as well as activity of superoxide dismutase (SOD) and peroxidase (POD). Meanwhile, chlorophyll contents were also augmented. In contrast, BL and OL reduced plant growth, biomass, chlorophyll contents and increased activities of SOD, POD, content of proline, MDA, and reduced the total soluble protein which suggested that plants grown under BL and OL undergo high environmental stress. These results depicted that all red lights, i.e., red, dark red, mixed red lights, can be effectively implemented for industrial production of C. capsularis.

Effect of Citric Acid on Growth, Ecophysiology, Chloroplast Ultrastructure, and Phytoremediation Potential of Jute (Corchorus capsularis L.) Seedlings Exposed to Copper Stress

“…Cu in excess causes generation of reactive oxygen species (ROS) such as superoxide radical (O .-), H 2 O 2 , singlet oxygen ( 1 O 2 ), and hydroxyl radicals (OH) [6,11,53,56]. Plants have a variety of antioxidants such as superoxide dismutase (SOD) and peroxidase (POD) and some specific metabolites play a key role in adaptation and survival of plants under metal toxicity.…”

Flax (Linum usitatissimum L.): A Potential Candidate for Phytoremediation? Biological and Economical Points of View

“…All these characteristics of flax make it a potential candidate to grow in metal contaminated soils and it can accumulate metal in the order of root > leaves stem > seed > fiber. Thus, flax can be used for phytoremediation and can provide 100% utilizable raw material which have no harmful residue as well as fully biodegradable waste [64,70,71].…”

Copper Uptake and Accumulation, Ultra-Structural Alteration, and Bast Fibre Yield and Quality of Fibrous Jute (Corchorus capsularis L.) Plants Grown under Two Different Soils of China

“…C. capsularis fibre-reinforced composites have been utilised in the automobile, footwear, construction, furniture, and different industries. It is also applied for the production of false ceilings, different compounds chlorophyll papers, toilet tiles, and tables [35,[37][38][39]. In addition to this, C. capsularis is an excellent candidate for the phytoremediation of different heavy metals which we have discussed in detail in our review literature [40].…”
