摘要
以不同抗性西瓜苗品种为材料,研究了西瓜苗期感染枯萎病菌(Fusarium oxysporumf.sp.niveum)病原菌毒素粗提液处理后在生长的不同时期、不同生长部位植株体内可溶性蛋白含量的变化情况,并分析了这些变化与植物抗病性的相互关系。结果表明,经毒素粗提液处理后,与对照相比,不同部位间可溶性蛋白含量存在明显差异。但是从总体上看,叶部可溶性蛋白含量最高、茎部次之、根部最低;一般情况下,在同一部位抗病品种的可溶性蛋白含量大于感病品种。
In this paper, three watermelon varieties with different resistance to Fusarium oxysporum Schlecht. f. sp. niveum that were used as experimental material. After treated with Fusarium oxysporum Schlecht. f. sp. niveum toxic culture filtrate, The protein content of plants was detected at different stages and in different position of plant like leaf, stem and root. The relationship between dissoluble protein and disease resistance were analyzed. The results showed as follows： After treated with Fusarium oxysporum toxin, compared with the control, there were many differences in protein content after treatment. But in total level, the leaf protein content was greater than the stem, and the stem protein content were greater than the root. In the same position of plant, the protein content of the resistant cultivar was always greater than the susceptible cultivar.
