叶片抗张强度是评价叶片机械强度的重要参数，与草坪草对牧草的选择性和草坪草的手感质量密切相关。虽然不同牧草品种叶片抗张强度的差异已被广泛研究，但有关草坪草叶片抗张强度的类似信息仍然缺乏。本研究首次对狗牙根和结缕草的8个品种和野生材料的叶片抗拉强度进行了测定和比较。结果表明，不同品种的叶片抗拉强度差异很大。dactylon和Z.粳稻栽培品种和野生种质。8个品种叶片抗张强度的平均值。栽培种和野生种之间的遗传多样性显著低于8个Z. japonica栽培种和野生种的遗传多样性，表明Z.粳稻一般比C.达克斯龙在附加试验中，研究了灌溉和施肥对香根草叶片抗拉强度的影响。达科塔龙Yangjiang和Z.日本Crowne也进行了分析。结果表明，少灌和过量施肥处理均显著降低了两种草坪草的叶片抗张强度，表明不同管理措施的组合可以改变草坪草的叶片抗张强度。这些信息大大提高了我们对草坪草叶片机械强度的理解。
Leaf tensile strength is an important parameter for evaluating leaf mechanical strength, which is closely related to preference of forage grasses and feel quality of turfgrasses. Although the variance of leaf tensile strength in different forage grass species has been extensively studied, similar information concerning the leaf tensile strength in turfgrasses are still deficient. In this study, the leaf tensile strength of eight cultivars and wild accessions of Cynodon dactylon and Zoysia japonica were determined and compared for the first time. The results indicated that leaf tensile strength are highly variable in different C. dactylon and Z. japonica cultivars and wild accessions. Average value of leaf tensile strength of the eight C. dactylon cultivars and wild accessions are much lower than that of the eight Z. japonica cultivars and wild accessions, suggesting Z. japonica are generally tougher than C. dactylon. In an additional experiment, the effects of irrigation and fertilization on leaf tensile strength of C. dactylon cv. Yangjiang and Z. japonica cv. Crowne were also analyzed. The results indicated that less irrigation and excess fertilization treatment both resulted in a significant reduction of leaf tensile strength of the two turfgrass species, suggesting leaf tensile strength of the turfgrasses under investigation may be altered through a combination of different management measures. This information greatly improves our understanding of leaf mechanical strength of turfgrasses.
