Impact toughness of the nanofiber embedded glass fiber-reinforced composites under water absorption condition
No full textThis study examines the impact toughness of nanofiber-reinforced glass fibre composites in water and ozone. Electrospinning and vacuum infusion implanted acrylonitrile-butadiene-styrene (ABS) and polycarbonate (PC) nanofibers in glass fiber-reinforced polymers (GFRP). Nanofiber reinforcement greatly increased water resistance and impact toughness over GFRP. The A10 (ABS-reinforced composite with 10-min electrospinning) had the lowest water absorption (4% after 500 h at 25°C) and maximum impact strength). GFRP absorbed 11% water and had a lower impact strength of 36.2 kJ/m2. Water absorption rates were increased at 65°C, although A10's 6.6% absorption was still best. Under ozone exposure, A10 demonstrated the greatest impact strength of 76 kJ/m2after 72 h at 50 ppm, whereas the PC-reinforced composite (P30) attained 70 kJ/m2
Genotypic Responses of Some Cereal Species to Speed Breeding Conditions
No full textTraditional plant breeding techniques can only create one generation of cool-season cereals per year, whereas speed breeding may produce an average of 5-6 generations in the same year. Speed breeding experiments were conducted at the Faculty of Agriculture, Dicle University, Turkey in a polycarbonate-covered greenhouse, including artificial light sources and air conditioners, in 2020. The study was set up as a randomized block design with four replicates. Eight durum wheat, ten bread wheat, and five barley genotypes were examined in this study. The anthesis time (days), plant height (cm), spike number per plant (number), spike length (cm), spikelet number per spike, grain number per spike, grain weight per spike (g), grain yield per plant (g), biomass per plant (g), and chlorophyll content were measured in this study. The data for the examined traits were analyzed using the JMP Pro 13 statistical package. Under speed breeding conditions, the total growing degree-days for durum wheat, bread wheat, and barley from seed germination to harvesting were 1186 °C, 1221°C, and 1239 °C, respectively. Genotypes reached anthesis 45% earlier in wheat and 50% earlier in barley under speed breeding conditions, compared with control. Under speed growing conditions, the increase in the spike number per plant caused a decrease in grain yield. The highest reduction in yield was observed in durum wheat, barley, and bread wheat, respectively. Optimizing plant density to minimize tillering and increase the amount of fertilizer used at the end of tiller formation will improve the effectiveness of speed breeding. Anthesis time, grain number per spike, spike length, spikelet number, and biomass traits measured under speed breeding could be used as selection criteria in bread wheat breeding studies. The results show that the cycle number in a year can change between 4.3 and 5.3 for durum wheat, bread wheat, and barley under speed breeding conditions
