分析9个湿地松抗病无性系和4个易感株针叶中的黄酮类物质及叶绿素的含量。结果表明,抗病和感病针叶中都存在黄酮类物质,且抗病针叶中的黄酮类物质和叶绿素的平均含量均略高于感病针叶中的平均含量,但方差分析显示二者差异未达到显著水平。
The contents of flavonoids and chlorophyll in the leaves of 9 wetland-resistant clones and 4 susceptible strains were analyzed. The results showed that there were flavonoids in the resistant and susceptible needles, and the average contents of flavonoids and chlorophyll in the resistant needles were slightly higher than those in the susceptible needles. However, The difference did not reach a significant level.
