The experiment was conducted to evaluate the effects of Ligustrum lucidum (LL) and Schisandra chinensis (SC) on the growth, antioxidative metabolism and immunity of laying strain male chicks. The results showed that diets supplemented with 1% of either LL or SC had no effects on the growth performance of chicks compared with the control. Furthermore, both LL and SC significantly reduced malondialdehyde (MDA) concentration of serum and heart of chicks (p<0.05). In addition, superoxide dismutase (SOD) activity of serum of the birds was significantly elevated by supplementation with SC (p<0.05). Glutathione reductase (GR) activity of heart and serum of the birds was significantly elevated by supplementation with LL or SC (p<0.05). LL supplementation significantly elevated antibody values against Newcastle Disease virus (NDV)(p<0.05) and lymphoblastogenesis (p<0.05) of the birds. The results suggest that diets supplemented with 1% of either LL or SC may improve immune function and antioxidant status of chicks.

A study on the shape memory properties of 6 layers bi-directional basalt fiber/carbon fiber hybrid composites with graphene oxide (GO) was presented in this paper. The hybrid composites were prepared by the vacuum infiltration hot pressing system (VIHPS). The macroscopic appearance of these composites was desirable, and their microstructure was satisfactory. According to the test results, with the content of basalt fiber decreased, the shape fixation ratio decreased, while the shape recovery ratio and shape recovery force all increased. The basalt fiber composite with 6 layers basalt fiber (B6) had a maximum shape fixation ratio of 94.94%, a minimum shape recovery ratio of 85.52%, and a minimum recovery force of 1.36 N. Compared with B6, the shape fixation ratio of the carbon fiber composite with 6 layers carbon fiber (C6) decreased by 10.43%, which was 84.51%. The shape recovery ratio and shape recovery force were increased by 9.60% and 3.31 times, and their values were 95.12% and 5.86 N, respectively. In addition, according to the temperature-recovery force curves, it was found that the seven groups of composites all reached their maximum shape recovery force when the temperature was about 110 °C. When the temperature was between 50 °C and 80 °C, the recovery force of the composite increased greatly, and then, the recovery force increased slightly. However, when the temperature was above the glass transition temperature (Tg), the recovery force gradually decreased.

Candidate gene mining of GA-mediated regulation of pear fruit shape

Fruit shape is one of the important traits for quality evaluation, classifi cation, and market grading of horticultural crops. In order to explore the genes regulating pear fruit shape formation, pear varieties ‘Huangguan’ and ‘Korla Fragrant Pear’ with signifi cant diff erences in fruit shape were selected as experimental materials. Through morphological observation, measurement of fruit longitudinal diameter and fruit transverse diameter, and fruit shape index analysis of the pear fruit growth and development period, the formation of pear fruit shape during the young fruit period was preliminarily determined. By analyzing the transcriptome data of ‘Huangguan’ and ‘Korla Fragrant Pear’ at the young fruit stage, 8993 diff erentially expressed genes were obtained, and the majority of the genes were annotated to the plant hormone signaling pathway, among which gibberellin-related genes accounted for 13.4%. Spraying GA 3 at the full-bloom stage can signifi cantly prolong the shape of oriental pear. The results of qRT-PCR showed that the expression level of the gibberellin metabolic pathway gene PbGA2ox11 in ‘Huangguan’ was signifi cantly higher than that in ‘Korla Fragrant Pear’. GA 3 treatment inhibited the expression of this gene in ‘Korla Fragrant Pear’, while PP 333 promoted the expression. It was speculated that PbGA2ox11 was most likely to regulate the shape of pear fruit by regulating gibberellin metabolism. This study provides a new method for studying fruit shape via the analysis of the gibberellin synthesis metabolic pathway, new resources for the rational use of plant growth regulators, and theoretical and technical support for cultivating excellent fruit shape.
