Fresh-cut water fennel was treated with a novel complex chemical solution and subsequently packaged prior to refrigerated storage. Chlorophyll degradation and lignification were investigated. The complex solution consisted of 1.16 g/L calcium lactate, 150 mg/L zinc acetate, and 15.29 mg/L salicylic acid. Chlorophyllase, Mg-dechelatase, and chlorophyll-degrading peroxidase activities of water fennel decreased after immersion in the complex solution, which delayed chlorophyll degradation and increased L* and a* values. Complex solution treatment also reduced phenylalanine ammonia-lyase (PAL) activity and, thus, inhibited accumulation of lignin. After the complex solution treatment, packaging in high-density polypropylene plastic bags further retained chlorophylls and alleviated lignification of water fennel. Treatment with a complex chemical solution and subsequent packaging can maintain the quality, delay senescence, and improve the shelf life of water fennel.

Phytic acid is involved in storage of phosphorus and minerals in soybeans. The effects of 6 basic plant hormones on phytic acid degradation were investigated. After 6 days of germination, phytic acid contents in soybean sprouts decreased by 70%, compared with day 0 soybeans. Zn and Fe bioavailability of 6-day-old germinating soybean both significantly increased (p<0.05), by contrast, Ca bioavailability decreased compared with controls. Phytic acid was detectable only in cotyledons of soybean sprouts during germination. In germinating soybeans, 39.19-45.85% and 54.15-60.81% of phytase existed in embryos and cotyledons, respectively. Unlike phytase, acid phosphatase was present mainly in cotyledons (92.57-97.51%). Among the 6 hormones, 50 mg/L indoleacetic acid (IAA) brought the highest degradation value to phytic acid content, meanwhile, Zn, Fe, and Ca bioavailability of IAA-treated soybeans were significantly (p<0.05) improved, compared with that of the control, respectively.

Phytase/phosphatase activities, the phytic acid content, and Zn, Fe, and Ca bioavailability values of 4-d-germinated soybeans and mung beans were investigated. Phytase and phosphatase activities of germinated soybeans and mung beans both increased, compared with raw beans. The phytic acid contents declined in germinated soybeans by 57.5% and in mung beans by 76.0%. Zn and Fe bioavailability values increased in germinated beans and Ca bioavailability decreased. For incubation, the highest bioavailability values of Zn, Fe, and Ca, respectively, were achieved using an exogenous phytase treatment in mung beans (47.6, 44.6, and 51.5%). Soybeans exhibited values of 64.7, 60.6, and 47.9%, respectively, after a combined treatment with endogenous and exogenous phytases. Germination improves Zn and Fe bioavailability values of beans by increasing enzyme activity, but is time-consuming. Incubation is more efficient for improvement of Zn, Fe, and Ca bioavailability values in a short period of time.

NaCl Treatment Improves Reactive Oxygen Metabolism and Antioxidant Capacity in Broccoli Sprouts
Lu Tian,Xinyue Li,Runqiang Yang,Zhenxin Gu 한국원예학회 2016 Horticulture, Environment, and Biotechnology Vol.57 No.6
We investigated membrane lipid peroxidation, reactive oxygen species (ROS) metabolism, antioxidant component content, and antioxidant enzyme activity to understand how NaCl regulates the growth of broccoli sprouts. NaCl treatment significantly increased ROS and malondialdehyde content, and electrolyte permeability in broccoli sprouts. Ascorbic acid and anthocyanin content also increased, simultaneously and significantly. During germination, treatments with 40 mM and 80 mM NaCl significantly promoted broccoli sprouts growth, likely because of ability to enhance antioxidant activity, thus alleviating the effect of stress.

Glutathione S-transferases (GSTs) is one of the main detoxification enzyme systems in insects and play important roles in insecticide resistance by direct metabolism, sequestration and antioxidant activity. Several GSTs genes in Spodoptera litura, a polyphagous agricultural pest, have been demonstrated to be overexpressed and involved in organophosphates and pyrethroids resistance. Previous studies have indicated the significant overexpression of two delta class GSTs genes (SlGSTd3 and SlGSTd4) in organophosphates and pyrethroids resistant populations. Here, they were heterologous expressed, and their metabolism activity and antioxidant activity were determined. Results indicated that the recombinant protein SlGSTD3 and SlGSTD4 both showed metabolism activity to phoxim and chlorpyrifos, but not to fenvalerate, cyhalothrin or beta cypermethrin. The metabolism activity of SlGSTD3 to phoxim and chlorpyrifos is higher than that of SlGSTD4. The recombinant vector of SlGSTD3 and SlGSTD4 both showed antioxidant activity after exposure to cumene hydroperoxide. Further modeling and docking analysis indicated that the 3D structure of SlGSTD3 and SlGSTD4 were well shaped for phoxim and chlorpyrifos, and the binding affinity for phoxim was stronger than that of chlorpyrifos. Our work provides evidence that SlGSTd3 and SlGSTd4 both play roles in phoxim and chlorpyrifos resistance in S. litura.

Broccoli sprouts produce several bioactive compounds and are recognized as a health-promoting vegetable. In this study,the eff ect of salinity (NaCl) on the growth of broccoli sprouts was investigated. Broccoli seeds were germinated for 4 and 8d with spraying 0–120 mM NaCl and then harvested to evaluate changes in endogenous hormones, photosynthetic indices,chlorophyll fl uorescence parameters and chloroplast ultrastructure. The growth of sprouts was signifi cantly promoted by lowsalinity (40 and 80 mM NaCl) and inhibited by high salinity treatment (120, 160 and 200 mM NaCl). In 8-day-old sproutstreated with 80 mM NaCl, levels of abscisic acid, cytokinin, brassinolide, indole-3-acetic acid and gibberellic acid weresignifi cantly enhanced, while net photosynthetic rate increased in low salinity conditions was due to the elevated chlorophyllcontent and increased photosystem II activity. Furthermore, low salinity increased the leaf area maximally in both 4- and8-day-old sprouts. Enlarged chloroplast and an increased number of grana also contributed to improved photosynthesis. Low salinity conditions induced endogenous growth hormone synthesis and improved photosynthesis, thereby promotingthe growth of broccoli sprouts. This study provides a theoretical basis for the improved production of broccoli sprouts inlow salinity conditions.
