- The factors effecting root tensile properties include root length, root diameter, root shape, etc. Based on analyzing the stress-strain relationship, hyperbola constitutive model, second-order parabola model and third-order parabola model were built up Pinus tabulaeformis root system. 3.
影响根系抗拉特性的主要因素有根长、根径、根形等。通过对油松抗拉应力应变关系的分析，构建了油松根系的双曲线本构模型、二阶抛物线模型和三阶抛物线模型。 - Root system biomass, root diameter are decreased from surface layer to deep layer.
根系生物量、主根直径整体上表现为从土壤表层到深层递减；品种间根颈特性差异明显； - The results indicate that the pull-resistance of shrub is impacted by configuration of the root system, maximum pull-resistance of single root and the amount of roots under stress. The maximum pull-resistance increases with root diameter increasing, and there is a good power function relationship between them.

结果表明，常N水平下高浓度CO2显著增加水稻和稗草的根干重、根体积、根总长和根直径，水稻对CO2浓度升高的响应强于稗草； - In contrast, the ratio of cortex width and root diameter was smaller.
而在旱生植物的根内，皮层宽度与根半径的比率则一般较小。 - The content of N, P, K, Ca and Mg in root decreased as root diameter increased.
根中氮、磷、钾、钙、镁含量随根径的增大而减少。 - With years of growth, plant height, leaf area, root number, root length and root diameter gradually increased, dry weight increased.
随着年份的增长，株高、叶面积、根数、根长和根粗逐渐增长，干重逐渐增加。 - The root system size and adventitious root diameter are various;
根系在大小和不定根直径方面存在变异； - PH value had significant effects on root number, root diameter, root length and root-shoot ratio of test-tube plantlets cultured with different media, pH value increased, root number and average root length decreased, root diameter and root-shoot ratio increased.
pH值对试管苗平均根系数量、根粗、根长和根冠比影响显著，生根数与平均根长随pH值升高而减小，平均根粗与根冠比随pH值的增大而增大； - The main results were as follows: 1. The film mulching cultivation had significant effect on plant height, main root growth, root diameter and the number of branches.
