海南高种椰子（CocosnuciferanL．HainanTall）的根、叶、椰水酯酶同工酶电泳结果表明，以叶作为材料分析椰子的同工酶谱较为适宜．叶样保存试验得出，椰子完整小叶于室温下（20～25℃）保存4d对酯酶活性影响不大。不同地区海南高种椰子酯酶同工酶谱表明，Rf＝0．56，Rf＝0．78两条谱带是海南高种椰子的特征谱带，同一地区株间及不同地区之间酯酶同工酶谱差异主要表现在Rf＝0．65，Rf＝0．67和Rf＝0．74的有无。 The root, leaf and coconut water esterase isozymes of Hainan Cocosnuciferan L.Hainan Tall showed that it was more suitable to analyze the isozymes of coconut with leaf as the material. Leaf-like preservation test showed that intact leaflets of coconut preserved at room temperature (20 ~ 25 ℃) for 4d had little effect on esterase activity. The results showed that the two bands of Rf = 0.56 and Rf = 0.78 were the characteristic bands of Hainan high-coconut species in different regions, and the esterase in the same region and in different regions Isoenzyme differences mainly reflected in the presence of Rf = 0.65, Rf = 0.67 and Rf = 0.74.
