摘要
通过对形态特征的观察和人工干旱胁迫试验,初步探讨了广东南亚热带地区广泛种植的狗牙根Cyn-odonda ctylon,细叶结缕草Zoysiatenui folia,地毯草Axonopos compressus,假俭草Eremochloa ophiuroides和广金钱草Deamodium styracifoli5种草坪草在土壤持续干旱过程中的形态变化,并分析了这5种草坪草的干旱适应能力以及它们的抗旱能力与生物学特性之间的联系。结果表明,在持续干旱胁迫条件下,5种草坪草的抗旱能力依次为:狗牙根>细叶结缕草>假俭草>地毯草>广金钱草。
Based on the observation of some morphological characters and the test of artificial drought stress, adaptability to drought stress in soil and morphological changes under drought stress in soil of five turfgrasses, i.e. Cynodon dactylon , Zoysia tenui folia , Eremochloa ophiuroide , Axonopus compressus and Deamodium styracifolium, widely planted in south subtropical area of Guangdong province were studied primarily. We also analyzed the relationship between the drought resistance of the five turfgrasses and their biological characters. The results show that the abilities of drought resistance for the five turfgrasses are from strong to weak as follows： Cynodon dactylon〉 Zoysia tenuifolia 〉 Eremochloaophiuroides 〉 Axonopus compressus 〉 Deamodium styracifolium.
