| 摘 要： | 本研究通过数码相机获取结缕草单株在秋季的株丛颜色变化图像,采用Sigmascan Pro 5.0图像分析软件,对4个结缕草材料的枯黄动态进行量化分析与比较。结果表明,用Sigmascan Pro 5.0进行结缕草单株秋季枯黄动态分析时,提取绿色像素点和黄色像素点的色相(H)和色饱和度(S)参数设置分别为H 32~107、S 10~100和H 10~32、S 25~100。参试的4个结缕草材料秋季枯黄由早到晚的顺序是:辽东结缕草、H2品系、青岛结缕草和胶东青结缕草,枯黄期与起源地的地理纬度有一定的相关性。与传统的目测评分法结果相比,数字影像处理测定结缕草枯黄率及动态变化为实测值,具有可重复性,结果更为准确。

| Abstract: | The dynamics of autumn color changes in four zoysiagrass accessions was analyzed by Sigmascan Pro 5.0 image analysis software using the photos of individual plants taken at intervals by a digital camera.The appropriate settings for selecting the green pixels were hue(H) 32-107,saturation level(S) 10-100,and for yellow pixels was H 10-32,The ranking order of the four accessions for dormancy date(from early to late) was Z.japonica cv.Liaoning,H2 strain,cv.Qingdao and Z.japonica var.pollida Nakai ex Honda cv.J... |
