| 摘 要： | 通过测定黑麦草(Loliumperenne)"长江2号"和"蓝天堂"2个品种间叶片的SPAD值、叶绿素含量和粗蛋白质含量,比较分析了这2个品种的SPAD值、叶绿素含量、粗蛋白质含量的差异以及三者之间的关系。研究结果表明,"长江2号"无论是SPAD值、叶绿素含量还是蛋白质含量都比"蓝天堂"高;这2个黑麦草品种的第1叶SPAD值、叶绿素含量和粗蛋白质含量都高于第2叶,但这2个品种的这3个性状差异不显著;"蓝天堂"和"长江2号"的SPAD值与叶绿素含量、粗蛋白质含量均呈显著正相关。

| Abstract: | SPAD value, chlorophyll content and crude protein content were determined between two Lolium perenne varieties,“Lan Tian Tang” and “Chang Jiang No.2”.At the same time, the difference and relationship in three traits between two varieties were compared and analyzed. The results showed that “Chang Jiang No.2” was higher than “Lan Tian Tang” in SPAD value, chlorophyll and crude protein content. The first leaf was bigger than the second leaf in the three traits of the two L.perenne varieties, but it was not significant difference. Either SPAD value and chlorophyll content or SPAD value and crude protein content between the two L.perenne varieties were significant linear relationship. |
