我们曾在1983和1984年指出:棉籽粗提液对兔血红细胞的凝集力与棉花品种抗枯萎病性存在相关现象;采用凝集力测定的方法即可在室内进行棉花抗枯萎病性快速测定。为了检验上述提法的可靠性,进行本次抗病性测定。(一)使用材料由宝山县良种场提供的四个棉种;“86-1”“80-159”“C72”和“临汾4023”。(二)测定方法先将四个棉种的棉籽分别去壳,各称取0.2克,剪碎,然后用无水乙醚分别浸泡脱脂三次(每次1小时),待乙醚倒掉并挥
We pointed out in 1983 and 1984 that the crude cottonseed extract showed the correlation between the agglutination ability of rabbit red blood cells and the resistance of cotton cultivars to fusarium wilt. The rapid determination of resistance to Fusarium wilt in cotton could be carried out by the method of agglutination. In order to test the reliability of the above formulation, the determination of the resistance was carried out. (1) The materials used are four varieties of cotton from Baoshan County Seed Farm; “86-1” “80-159” “C72” and “Linfen 4023”. (B) determination of the first four cotton seed cottonseed were shelled, respectively, said to take 0.2 grams, cut, and then were soaked in anhydrous ether degreasing three times (each 1 hour) until the ether drained and play
