| Abstract: | There were genotype differences in nitrogen uptake and utilization in ramie, and SPAD value could well reflect the differences. In this study, 26 ramie germplasm were selected as materials, SPAD values of ramie plants were measured at flourishing and mature stages, and SPAD values of ramie plants were selected as high luminous efficiency evaluation indexes by t-test and variance analysis. |
