The Relationship Between Wheat Seed Weight, Infection by Fusarium culmorum or Microdochium nivale, Germination and Seedling Disease

The distribution of seeds by weight for three lots of winter wheat cv. Avalon infected by Fusarium culmorum and three lots of winter wheat cv. Riband infected by Microdochium nivale was determined. The distribution of infected seeds within each seed lot was then determined by isolating F. culmorum from seeds on moist filter paper and M. nivale from seeds on potato dextrose agar. The distribution of M. nivale infected seeds between seeds of different weight was similar to that of the seed lot as a whole, whereas the distribution of F. culmorum was greater in light seeds than heavy seeds. The percentage germination of infected seeds decreased with seed weight. A similar situation was found with respect to seedling emergence in compost for F. culmorum infected seeds. However, with M. nivale infection, similar numbers of seedlings emerged from both light and heavy infected seeds. Seed treatment with guazatine increased seedling emergence for both light and heavy seed infected by M. nivale. However, seedling emergence from F. culmorum infected seed was poor even following treatment with guazatine. Poor emergence was most evident from light seed.

本试验利用厌氧折流板反应器（ＡＢＲ）中温处理豆制品废水,对其启动过程和提高负荷运行过程进行了研究。试验表明,ＡＢＲ处理豆制品废水优势突出：其启动过程快,易培养出颗粒化的活性污泥;稳定运行时,容积负荷可达到１４．３ｇＣＯＤ／（Ｌ·ｄ）,ＣＯＤ去除率能保持８０％以上;具良好的抗冲击负荷和抗低ｐＨ的能力;ＭＰＮ计数表明不同时间、不同区段的三大类菌群呈现明显的规律性变化     

诱变处理后幼苗碳素养分合成及其运转

运用１４ Ｃ标记示踪技术,测定诱变处理后幼苗的光合作用、呼吸作用,并考查碳素营养运转情况,结果表明：不同处理对光合作用影响很小,但呼吸作用随复合剂量加大而增加,同时输出物质减少。     

磁处理土壤对作物生长影响的初步研究

磁处理土壤可以促进番茄、黄瓜和水稻的苗期生长,提高作物对氮磷钾主要养分的吸收能力,影响最大的是氮。在磁处理的土壤上黄瓜和小麦叶面积与叶绿素含量增加,黄瓜的品质提高。对油菜、小麦和黄瓜的研究证明磁处理土壤对作物的产量有一定的影响。     

Improvement and retardation of wound healing: effects of pharmacological agents in laboratory animal studies

Impaired wound healing is an important problem; retardation of healing may be induced by endogenous and/or exogenous factors and treatments capable of ameliorating these effects are needed. The effects of solutions containing light ichthyol or povidone iodine, of ointments containing zinc oxide (ZO) and/or cod liver oil (CLO), and of a polyurethane-hydrogel foam wound dressing were examined on healing of full-thickness murine skin wounds impaired by systemic dexamethasone. The effects of the ointments were also studied on murine skin ulceration induced by subcutaneous sodium dodecyl sulphate solution. Light ichthyol at 1% and 2% but not at 5% and 10%, povidone iodine at 1% and the foam accelerated impaired healing. The ointments containing ZO or CLO accelerated healing of impaired full-thickness wounds and of ulcerated skin; ZO and CLO were synergistic. These studies demonstrate the value of murine models in the evaluation of agents employed in veterinary wound dressings.     

甲醛处理对豆饼干物质和蛋白质瘤胃降解率及胃蛋白酶消化率的影响

豆饼用２ｇ／ｋｇＤＭ甲醛处理后,１０ｈ瘤胃干物质（ＤＭ）降解率从８７．１９％下降到豆饼含水量为１４％和６０．９３％和含水量１８％时的５６．２９％,粗蛋白降解率从８７．６９％分别下降到４８．３６％和４３．４３％,随着甲醛用量的增加,干物质的粗蛋白的降解率进一步下降,但下降幅度减少。在甲醛用量低于２ｇ／ｋｇＤＭ的情况下,甲醛用量对ＰＨ为４．５时的胃蛋白酶４ｈ和８ｈ干物质和粗蛋白消化率没有明显影响,但
