- 摘要:
- 叶色和花色是海棠非常重要的观赏特性之一，也是观赏海棠品种选育的关键指标。现以绚丽海棠实生后代为试材，用色差计测定了海棠不同株系、不同部位的叶片及花瓣的明亮参数L、色相参数a和b的值，分析了海棠叶色及花色之间的相关性。在不同时期研究了海棠叶片叶色的变化规律。结果表明：海棠的叶色L、a、b与花色之间存在明显的正相关关系；在前后2个时期（4月6日、5月6日）海棠叶片的L、a、b发生了显著变化，其中a的色差值变化最大、b次之、L最小；海棠长枝顶梢到基部叶片的a、b值均呈现出显著变化，并且表现出一定的变化规律，即b值从顶梢到基部逐渐增大，而a值从顶梢到基部逐渐减小。
- Abstract:
- Leaf color and flower color are one of the most important ornamental characteristics of Malus chaenomeles，and it is also a key indicator for the selection of Malus chaenomeles varieties.Malus chaenomeles seedlings was used as test materials，the determination of different strains of cherry-apple tree bright parameters L，color parameters of leaves and petals of different parts of the a and b values with colorimeter，the correlation between leaf color and flower color was analyzed.The change of leaf color in Malus chaenomeles leaves was studied in different periods.The results showed that there was a positive correlation between the L and a，b of Malus chaenomeles leaf color.From April 6th to May 6th，the contents of L，a，b value of Malus chaenomeles had undergone significant changes.Among them，the color difference of a changed most，and the second was b，L was minimum；the a and b values of the leaves from the long branch to the base of Malus chaenomeles trees showed significant changes，and showed a certain change law，that was，the b value increased gradually from the top to the base，while the a value decreased gradually from the tip to the base.
