摘　　要：收集了四川境内的8份具有生境或形态差异的野生马蹄金材料,并以3份进口马蹄金为对照,对它们的物候期、抗逆性和坪用价值进行研究。结果发现,四川野生马蹄金与对照材料在外观上有明显的差异,进口材料叶色墨绿、叶片肥大、叶柄长、叶层高,而野生材料则叶色翠绿、叶片小、叶层矮。根据马蹄金草坪目测评分标准,野生材料评分值为8.33,与进口材料评分值8.35相当。2类材料在开花、结实期和绿期上也有较大差异。The phenological-period, resistance and turf-quality of 8 wild dichondra materials collected in Sichuan, and 3 cultivated dichondra materials imported from USA as the contrast were studied. The filed observation result showed that wild dichondra had light-green blade-color, thin blade and petiole, lower blade-layer, while cultivated dichondra had blackish-green blade-color, loose blade , thick petiole and higher blade-layer. According to the estimation standard of dichondra turf, wild dichondra was marked 8.33 nearly equals cultivated dichondra marked 8.35. There were also great differences in blooming time, mature period and green period between two types of material.
