[Objective] This study aimed to investigate the effects of space mutation on the activities of protective enzymes in different strains of cichorium intybus l. and provide theoretical.basis for screening drought-tol.rant pl.nts in southern karst area. [Method] C. intybus seeds were sent into outer space by ＇Shijian No.8＇ seed- breeding satel.ite. The new strains and original.variety of C. intybus l. were used as experimental.material. to determine the activities of catal.se （CAT）, peroxidase （POD）, superoxide dismutase （SOD）, and mal.ndial.ehyde （MDA） content. [Resul.] The resul.s showed that MDA content in PA-82, Puna chicory and PA-43 increased gradual.y with the increase of water stress duration, which was enhanced by 0.575, 0.72 and 0.844 μmol.g respectivel. at 12 days. In addition, the activities of SOD, POD and CAT increased rapidl.; 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%, respectivel.; 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%, respectivel.; 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%, respectivel.; subsequentl., the activities of these three protective enzymes were reduced significantl.; 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, respectivel.; the activi- ties of POD were reduced to 3 145, 2 876 and 2 753 U/（g·min） , respectivel.; the activities of CAT were reduced to 587.2, 698.1 and 584.1 KU/l. respectivel.. [Con- cl.sion] According to the resul.s of comprehensive eval.ation, drought resistance in three C. intybus varieties exhibited a descending order of PA-82 〉 Puna chicory 〉 PA-43.

为探讨氮素和微生物菌剂对牧草粗蛋白含量和粗纤维含量的影响,选用‘将军’菊苣(cichorium intybus l.)作为试验品种,采用盆栽和定量分析的方法,研究了菊苣经氮素和微生物菌剂处理后粗纤维和粗蛋白含量以及叶绿素的变化。试验结果证明氮素和微生物菌剂处理显著提高‘将军’菊苣的粗纤维和粗蛋白的含量,平均达到11.84%和10.25%;茎叶部粗蛋白和粗纤维含量平均达到10.08%和13.14%,根部粗蛋白和粗纤维含量平均达到7.56%和13.1%;短期内菊苣粗蛋白质含量均在8.56%以上,短期内菊苣粗纤维含量均在12.61%以上。氮素和微生物菌剂共同施用的效果优于只施氮素或只施微生物菌剂,氮素和微生物菌剂配施能显著提高‘将军’菊苣的营养成分和品质。
