Abstract
High performance liquid chromatography was used to study the relationships between resistance and content of cucurbitacin B in cucumber.The results showed that the highest content of cucurbitacin B in roots before inoculation is in sour cucumber(1.31 μg/g),followed by the Africa horned cucumber(0.85 μg/g) and the minimum Beijingjietou(0.35 μg/g),indicating that the ontology content of cucurbitacin B in sour cucumber were higher.The content of cucurbitacin B in sour cucumber,Africa horned and Beijingjietou were increased to 3.88,2.67,0.49 μg/g and increased by 2.57,1.82 and 0.14 μg/g respectively,compared with the corresponding controls after inoculation,indicating the increased content of cucurbitacin B in sour cucumber is greater.The infected degree of sour cucumber is lower indicating its resistance is higher.The correlation analysis showed that there was positively correlation between nematode-resistant abilities of crops and the content of cucurbitacin B in roots,the higher its content,the stronger the resistance.The resistance in sour cucumber for its chemical aspects results from its higher levels of cucurbitacin B in roots.
