On the basis of investigating the resource and utilization of Iris plants in Nanjing, Hangzhou and Wuxi, the paper selected five plants: Iris pseudacorus、 Iris sanguinea、 Iris kaempferi、 Iris japonica、 Iris tectorum to find their tissue culture technology and shade tolerance with lots experiments. The results were summarized as follows:In the culture of Iris sanguined, The shooting tip in the spring and the medium supplemented with 6-BA(1mg/L)+NAA(0.2mg/L) testified the best grouping.

本文在对南京、杭州、无锡等地鸢尾属植物及其园林应用实地调查的基础上，以黄菖蒲、溪荪、花菖蒲、蝴蝶花、鸢尾等五个种为实验材料，从其部分种的组织培养技术和耐荫性两方面入手，通过大量的实验并对所得数据进行统计分析，得出以下结论：溪荪的组织培养中，以春季萌发的茎尖为外植体，以MS培养基附加低浓度的6-BA(1mg／L)与NAA(0.2mg/L)为最佳的诱导分化的组合。

The findings indicated that chicken leptin protein could markedly increase abdominal fat deposition in yellow-feathered chicken, did not have significant effect on weight or protein content of leg and breast muscle, fat and water content nor on serum T3 and T4 indices.

本试验首次用主动免疫的方式来检测重组鸡leptin蛋白的生物学活性，结果表明leptin蛋白在黄羽肉鸡体内能明显的增加脂肪沉积，对胸腿肌重量及胸腿肌中蛋白质、脂肪和水分的含量没有明显影响，对血清中T3、T4指标没有影响，对料肉比、期末体重和体增重等生产性能指标的改善有阶段性的作用。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
