苦瓜两种叶色值与果色的相关性分析

Correlation Analysis of Fruit Color with SPAD Reading and Leaf Color(Hue Angle)in Bitter Gourd

以26份苦瓜自交系为材料,利用叶绿素计和色差计分别测定苦瓜叶片SPAD值、色度角(H°)及果实色度角(H°),并对三者之间的相关性进行了分析。结果表明:苦瓜不同自交系的叶片SPAD值、色度角以及果实色度角均存在极显著差异;叶片SPAD值和色度角均与果实色度角呈显著相关,叶片SPAD值和叶片色度角呈极显著相关。说明苦瓜叶色可以为果色选种提供一定的参考。

The leaf SPAD reading and hue angle(H°)of both leaf and fruit in 26 Momordica charantia L.inbred lines were measured by Minolta SPAD-502 and Minolta chroma meter CR-300,respectively.The correlations between leaf SPAD reading,leaf color and fruit color were calculated.The results indicated that leaf SPAD reading,leaf color and fruit color have very significant differences in different bitter gourd inbred lines.Meanwhile,both leaf SPAD reading and leaf color showed a significant correlation with fruit color,and leaf color was very significantly correlated with leaf SPAD reading.
