In light of this, two field experiments were conducted to evaluate the performance, yield, oil production and composition, as well as active constituents of Rocket(Eruca sativa Mill) cultivated in calcareous soil under saline water irrigation. Foliar sprays containing condensed molasses soluble(CMS), zinc(Zn), and boron(B) alone or in combination were used for irrigation. The data obtained from measuring various parameters of Rocket following foliar spraying with CMS, Zn, B or their combinations demonstrated that most treatments resulted in a significant increase in these parameters. The highest values for most measurements were observed when foliar application included all three components(CMS + Zn + B), resulting in a seed yield of 184.6 g/m2and an oil content of 675.3 kg/ha. Compared to the control group, the macronutrient content of N, P, K, Mg, and Ca increased by 34.4%, 56%, 42%, 45%, and 39% respectively in the seeds treated with these components.Furthermore, carbohydrates, proteins, phenolics flavonoids, and antioxidants showed increases of 24%, 34%,21%, 43%, and 28% respectively compared to the control group. Gas-liquid chromatography analysis identified ten components present in the seed oil characterized by higher unsaturated fatty acids ranging from 81.28% to92.28% and lower saturated fatty acids ranging from 6.72% to 8.21%. Therefore, foliar spray application including CMS, zinc, and boron can help alleviate salinity effects on Rocket plants grown under saline water irrigation conditions while improving growth, yield, oil production, and nutritional content such as total carbohydrates, proteins, and macronutrients levels.展开更多

Twenty native cultivars representing Yunjie-growing eco-types in China were selected as material in this study. Twelve out of the 64 tested random decamer primers were able to identify 131 stable RAPD bands from these Yunjie cultivars. Of them 105 bands, or 80.15% of the total, were polymorphic. Most Yunjie cultivars from the same ecotype had their characteristic DNA bands. Cluster analysis by unweighted pair group method of arithmetic means(UPGMA)suggested that the 20 Yunjie genotypes could be divided into four groups. The genetic distances among the 20 cultivars varied from 0.117 8 between Shuozhou and Shenchi to 0. 499 4 between Hetian and Xiliang. Hetian alone could be a new type of Yunjie identified in China because it had the greatest genetic distance from all the other tested cultivars. These results indicate that Chinese Yunjie have abundant genetic diversity. Classification of Chinese Yunjie based on the RAPD information was in good agreement with the relationships between these Yunjie cultivars in their geographic origins and their plant morphology.展开更多

METHODS： Gastric acid secretion studies were undertaken using pylorus-ligated rats. Gastric lesions in the rats were induced by noxious chemicals including ethanol, strong alkalis, indomethacin and hypothermic restraint stress. The levels of gastric wall mucus （GWM）, nonprotein sulfhydryls （NP-SH） and malondialdehyde （MDA） were also measured in the glandular stomach of rats following ethanol administration. The gastric tissue was also examined histologically. The extract was used in two doses （250 and 500 mg/kg body weight） in all experiments. RESULTS： In pylorus-ligated Shay rats, the ethanolic extract of Rocket ＂Eruca sativa L.＂ （EER） significantly and dose-dependently reduced the basal gastric acid secretion, titratable acidity and ruminal ulceration. Rocket extract significantly attenuated gastric ulceration induced by necrotizing agents （80% ethanol, 0.2 mol/L NaOH, 25% NaCl）, indomethacin and hypothermic restraint stress. The anti-ulcer effect was further confirmed histologically. On the other hand, the extract significantly replenished GWM and NP-SH levels, as well as the MDA level significantly reduced by extract pretreatment. CONCLUSION： Rocket extract possesses antisecretory, cytoprotective, and anti-ulcer activities against experimentally-induced gastric lesions. The anti-ulcer effect is possibly through prostaglandinmediated activity and/or through its anti-secretory and antioxidant properties.展开更多
