Abstract Development process of tumorous stem characters were studied by using a mustard variety Fuza No. 1 sown on Aug 30 and Sep 9. The results showed that the development processes of vertical diameter, horizontal diameter,fresh weight and dry weight could be described by Logistic equation y= k(1+ e(a+bt))-1 and the tumorous stem index met the type of regression curve y=a+b1t+b2t2. The beginning of linear-growth period of vertical diameter,horizontal diameter,dry weight and fresh weight were 2.1-9.6 days, 17.8-19...
