摘要: 利用SPAD-502叶绿素仪测定青引1号燕麦(Avena sativa cv.Qinghai No.1)、青海甜燕麦(A.sativa cv.Qinghai)、黑麦(Secale cereal)、特高多花黑麦草(Lolium multiflorum cv.Tetragold)、长江2号多花黑麦草(L.multiflorum cv.Changjiang No.2)5个牧草品种叶片上的SPAD值,发现青海甜燕麦和青引1号燕麦的SPAD值显著高于黑麦和两个多花黑麦草品种(P0.05);同一叶片上的SPAD值都表现出叶尖部叶中部叶基部的特点;叶中部的SPAD值更接近平均值,且数据稳定,可以作为试验牧草SPAD值测定的适宜部位。

Abstract: In the present study, SPAD values of different positions on the same leaf were measured using the equipment SPAD-502(Soil Plant Analysis Development) for 5 herbage grasses, including Avena sativa cv. Qinghai No.1, A.sativa cv. Qinghai, Secale cereal, Lolium multiflorum cv. Tetragold, and L.multiflorum cv. Changjiang No.2. The results indicated that SPAD values of A.sativa cv. Qinghai No.1 and A. sativa cv. Qinghai were significantly higher than that of S.cereal,L. multiflorum cv. Tetragold and L. multiflorum cv. Changjiang No.2. Moreover, the SPAD value stabilization varied from position to position on the same leaf. SPAD value from the same leaf declined from the tip to the middle part and to the bottom of a leaf. The measured SPAD values at the middle part of a leaf were more stable than those from the tip and the bottom which could be used as the appropriate candidate part for SPAD measure.
