In this study, the weighing and drainage methods together with paraffin section and kit-based spectrophotometry indicted the Drumstick-forming characterized the extremely significant increases in the fresh weight (FW) per plant and starch granule density (SGD), the significant increases in the dry weight (DW), volume, amylose content (AC) and AC/amylopectin contents (APC) per plant, the significant decrease in the drying rate (DR) per plant and the non-significant increases in the APC, total starch content (TSC) and trehalose content (TC) per plant of the 2-year-old taproots, and the extremely significant increases in the FW, DW and volume per plant, the significant increase in the TC per plant, the extremely significant decrease in the SGD, the significant decrease in the AC, APC and TSC per plant and the non-significant decrease in the AC/APC and DR per plant of the 3-year-old taproots.

Herein, a novel bio-based curing agent, PA–DAD, has successfully been developed for EP that provides both mechanical reinforcement and flame retardancy. This agent was prepared via a straightforward neutralizing process between phytic acid (PA) and 1,10-diaminodecane (DAD). A series of bio-based curing agents labeled PA₁–DAD₆, PA₁–DAD₉, and PA₁–DAD₁₂ were produced by adjusting the PA and DAD stoichiometric ratio. During the curing process, PA–DAD dissociates into PA and DAD, PA functions as an ionic cross-linking site within the EP structure. This considerably enhances the mechanical properties of the EP compared with using DAD alone as a curing agent. As a consequence, the tensile, flexural, and the impact strength values of EP/5 % PA₁–DAD₆ enhanced by 103 %, 70 %, and 168 %, respectively, compared with EP/5 % DAD at a 5 wt% addition. Additionally, the tensile and flexural toughness values of EP/5 % PA₁–DAD₆ were 1250 % and 649 % higher compared to those of EP/5 % DAD, respectively, demonstrating the exceptional toughening effect of PA–DAD on EP. Furthermore, the flame retardancy of EP/PA–DAD improved because of the high P content in PA–DAD. Compared with EP/5 % DAD, EP/5 % PA₁–DAD₆ shown decreases of 10.7 % in peak heat release rate, 8.4 % in total heat release, and 13.6 % in total smoke production.

This study addresses the feasibility of using cellulose nanoparticles in vulcanized NR composites. For this purpose, two different hydrolysis procedures using sulfuric acid and the less aggressive phosphoric acid were performed. These nanoparticles were then added to different amounts of NR compound. The effects of the CNCs on the vulcanization of the NR compound were evidenced by the formation of a zinc-cellulose-rubber complex, which reduced the optimal vulcanization time and increased the NR compound cure rate, particularly for the samples treated with phosphoric acid. In addition, the formation of this complex structure affected the morphology and mechanical properties of the composites. In particular, the tensile strength, elongation at break, and modulus at 300 % of the composites with nanocellulose treated with phosphoric acid increased by 90 %, 16 %, and 51 %, respectively, compared to the NR compound.
