宁镇丘陵地区假俭草资源坪用特性初探

         

摘要

Growth characteristics, winter survival and flowering characteristics of 8 wild centipedegrass (Eremochloa ophiuroides) accessions, collected from hilly areas of Ningzhen, were observed. Their turf quality was also evaluated. The results showed that growth characteristics, winter survival and flowering characteristics were quite different among different accessions of centipedegrass. Pukou Laoshan centipede grass (El0) was the most different from other types. It showed slower growth, fewer branches, later wil ting, longer bluegreen period and stronger winter survival. Nanjing Zhongshan centipedegrass (Ell) had the fastest growth rate of a single stolon. The centipedegrass (E12) collected from Yizheng Xinji of Jiangsu Province had the highest quality and score on the comprehensive evaluation. The centipedegrass (El0) collected from Pukou Laoshan in Nanjing showed yellow stems, white stigma and yellow anthers. However, other centipedegrass of the hilly areas of Ningzhen had purple stems, red stigma and anthers. All the materials reported here provide favorable germplasm resources for the breeding of centipedegrass in the area of Ningzhen.%以宁镇丘陵地区的8份野生假俭草(Erernochloaophiuroides)为试验材料,系统地观测其生长特性和越冬性,并对其草坪质量进行了评价。结果表明,8份假俭草的生长特性和越冬性均有较大差异。其中以采自浦口老山的假俭草(EIO)匍匐茎生长速度、分枝数、绿色期以及越冬性同其他材料相比差异最显著;匍匐茎生长速度最快的是采自南京钟山的假俭草(E11),而叶片质地最好和综合评价得分最高的是仪征新集的假俭草(E12)。从花器宫色泽来看,采自浦口老山的假俭草(EIO)具有黄色茎、白色柱头和黄色花药,而其他7个材
