The Correlation of the Resistance to Root Lodging with Growth Angle, Diameter and Pulling Strength of Crown Roots in Rice Seedlings
Oryza sativa L Pushing resistance Crown root Root lodging resistance Growth angle
2009/7/9
Twenty typical Indica and Japonica rice varieties were tested for resistance to root lodging using a push-pull gauge for two years. Pushing resistance varied from 0.56 N to 2.57 N among the 20 varieti...
Varietal Difference and Genetic Analysis of Adventitious Root Formation at the Soil Surface during Flooding in Maize and Teosinte Seedlings
Adventitious root Genetic resource Maize Seedling
2009/7/8
Adventitious root-forming (ARF) ability, at the soil surface, is most important for adaptation of the plant to soil flooding or waterlogging. We evaluated the ARF ability of maize and teosinte seedlin...

重铬酸钾对蚕豆根尖细胞致畸效应的研究Study on Teratogenic Effect of Potassium Dichromate on Vicia Faba Root Tip Cells
重铬酸钾 蚕豆 微核率 色体畸变率
2008/1/8
摘要
以蚕豆根尖为材料，研究重铬酸钾对蚕豆根尖细胞的致畸效应。采用蚕豆根尖细胞的微核试验和染色体畸变试验方法，以不同浓度的重铬酸钾为诱变剂，测定蚕豆根尖细胞的微核率和染色体畸变率。结果表明：重铬酸钾能诱发较高频率的微核率，即在一定浓度范围内，其微核率随重铬酸钾处理浓度的升高而增加，但高于一定浓度后反而呈下降趋势；不同浓度的重铬酸钾均使蚕豆根尖细胞有丝分裂指数增大；重铬酸钾还能诱导蚕豆根尖细胞产生...
