用微量凯氏定氮法,对根结线虫(Me(?)oidohyne incognita)的寄主蕃茄上根结和同株健根、健株健根蛋白质含量测定表明,寄主在整个生长期间,根结内蛋白质含量在一定时间,显著高于同期同株健根,也高于同期相似部位的健株健根,且根结中蛋白质含量变化都是由低到高再到低即根结越大,其蛋白质含量越多,同株根结与健根中蛋白质含量的差数在寄 The content of protein in root tuber and root tuber of host plant of root knot nematode (Me (?) Oidohyne incognita) was determined by micro Kjeldahl method. The results showed that during the whole growing period, Protein content at a certain time, significantly higher than the same period of the same root, but also higher than similar parts of the same period healthy roots, and the root knot protein content changes from low to high and then the lower the root knot greater its The more protein content, the same root and root tubercle root protein content difference in the mail
