Endogenous IAA, DHZ+DHZR, iPA increased significantly during the floral bud formation, while Z+ZR remained changed. The levels of cytokinins, DHZ+DHZR, iPA, and Z+ZR all increased significantly during the vegetative bud formation, however IAA level was reduced during the first 7 days of culture and increased to two thirds of initial values on the day when the bud primordia were formed. The results suggested that the initiation of floral buds was associated with a high IAA/CTK ratio, whereas the induction of vegetative bud differentiation was related to a low IAA/CTK ratio.展开更多

This study was designed to evaluate the protective effect of Cichorium intybus L. and Cinnamon mixture infusion (2.5 and 0.5 g/100mL and twice/day) on patients with NAFLD. This before-after clinical trial study was performed on 25 patients with NAFLD. They were administered the mixture of extract prepared in special bags twice a day for 30 days. Hepatic and metabolic markers of NAFLD like alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphates (ALP), fasting blood sugar (FBS), cholesterol (chol), triglycerides (TG), high-density lipoprotein (HDL) and low-density lipoprotein (LDL) in plasma and also, fatty liver ultrasonographic grading were determined before and after using the extracts. 30-day treatment with extracts in NAFLD patients resulted in a significant decrease in ALT and AST. FBS, TG and ALP were also decreased after administration of the extracts but not significantly. A significant linear correlation was found between age and ALP, and between gender and liver enzymes. It is concluded that the mixture of Cichorium intybus L. and Cinnamon extracts has some benefits in NAFLD patients making them valuable for future investigations.展开更多

[Method] C. intybus seeds were sent into outer space by ＇Shijian No.8＇ seed- breeding satellite. The new strains and original variety of C. intybus L. were used as experimental materials to determine the activities of catalase （CAT）, peroxidase （POD）, superoxide dismutase （SOD）, and malondialdehyde （MDA） content. [Result] The results showed that MDA content in PA-82, Puna chicory and PA-43 increased gradually with the increase of water stress duration, which was enhanced by 0.575, 0.72 and 0.844 μmol/g respectively at 12 days. In addition, the activities of SOD, POD and CAT increased rapidly; at 9 days, the activities of SOD in PA-82, Puna chicory and PA-43 were enhanced by 878.9, 809.2 and 711.1 U/g, with the increas- ing range of 139.1%, 136.7% and 121.1%, respectively; the activities of POD were enhanced by 4 397, 3 754 and 2 767 U/（g ·min）, with the increasing range of 265.84%, 257.65% and 204.06%, respectively; the activities of CAT were enhanced by 402.1, 277.1 and 170.9 KU/L, with the increasing range of 73.08%, 39.69% and 26.20%, respectively; subsequently, the activities of these three protective enzymes were reduced significantly; at 12 days, the activities of SOD in PA-82, Puna chicory and PA-43 were reduced to 1206.5, 1144.7 and 1108.6 U/g, respectively; the activi- ties of POD were reduced to 3 145, 2 876 and 2 753 U/（g·min） , respectively; the activities of CAT were reduced to 587.2, 698.1 and 584.1 KU/L, respectively. [Con- clusion] According to the results of comprehensive evaluation, drought resistance in three C. intybus varieties exhibited a descending order of PA-82 〉 Puna chicory 〉 PA-43.展开更多

[Method] Effects of dairy cattle ma- nure and chemical fertilizer on fertility of soils grown with Cichorium intybus were in- vestigated through a pot experiment. [Result] After manure of dairy cattle was ap- plied, it can be concluded that organic matter, total N, total P, alkali-hydrolyzable ni- trogen, available P, activities of urease and invertase in soils increased by 0.14-1.28 times, 43.8%-79.7%, 17.4%-30.8%, 147%-188%, 7 times, 17.2%-38.5%, and 1.36%- 3.34%, respectively. Furthermore, organic matter, total N. urease and invertase activi- ties in group of M7F3 increased most; total P and available P achieved the best in group of M3F7. These indicated that the applied manures of dairy cattle would maintain and improve soil fertility, providing better soils for Cichorium intybus. [Conclusion] The research provides reference for recycling of cattle manures and construction of ecological cyclical pattern of ＂grass planting-cattle breeding-methane fermentation-returning of manures into fields＂.展开更多
