  • 小麦抗性淀粉与主要营养成分的相关性研究(英文)

    张志转;陈多璞;吴殿星;

    以全国94个春小麦品种为材料,研究小麦表观直链淀粉含量(AAC)、蛋白质、脂肪与生面粉和熟面粉抗性淀粉(RS)含量的相关性。结果表明,AAC与生面粉和熟面粉RS含量均呈极显著正相关;蛋白质含量与生面粉RS含量呈极显著负相关;脂肪含量与生面粉和熟面粉RS含量均相关不显著;生面粉与熟面粉RS含量呈极显著正相关。

  • Antioxidation effect of Carya cathayensis sarg oil

    [Objective] The antioxidation effect of Carya cathayensis sarg (CCS) Oil was qualitatively and quantitatively detected. [Method] 50 male mice were divided into 5 groups equally and randomly and among them,the three groups were either negative,or model control,or positive control (ginseng saponins),respectively. Two remaining groups were orally fed with low and high dosages of CCS oil ((9 ml/(kg·d) and (33 ml/(kg·d)),respectively. All groups were injected D-galactose through hypodermic except the negative control ones which were only treated with equals amount of distilled water. The superoxide dismutase (SOD),maleic dialdehyde(MDA) and monoamine oxidase(MAO) were analyzed with blood sample and brain tissue 42 days post treatment. [Result] It was showed that the activity of SOD enzyme was increased in the CCS oil groups,while MDA and MAO content were decreased in the CCS oil groups compared with that of other groups with significance observed in the group fed with high dose of CCS oil. [Conclusion] The result indicated that the CCS oil has the ability of antioxidation and is useful to human health.

  • 多倍体西瓜种壳性状的基因效应分析(英文)

    陈娟;

    [目的]通过遗传效应分析,为三倍体西瓜种壳性状改良提供依据。[方法]选用西瓜4个生态型的6个四倍体自交系作母本和同一生态型的6个二倍体自交系作父本,按NCII(North Carolina II)遗传交配设计方法配制6×6个杂种F1,采用加性-显性遗传模型分析西瓜种壳性状的遗传效应。[结果]剖面种壳数受基因的加性效应、显性效应以及环境效应共同控制。败育种壳长和宽的加性效应显著,环境(机误)方差达到显著或极显著水平。剖面种壳数与边缘可溶性固形物含量呈加性显著负相关,相关系数为0.631;与番茄红素和干物质含量呈显性负相关,相关系数为0.288和0.386。败育种壳长与种壳宽成极显著加性正相关,相关系数为0.983。[结论]该研究为三倍体西瓜育种中的基因改良提供参考。
