| With the callus differentiation and shoot for 4 weeks of sugarcane variety ROC 22 and Yuetang 93-
159 as materials, this paper determined the concentration of imazapyr in callus differentiation stage and shoot stage
of the two sugarcane varieties. The results showed that the callus tissue and shoot for 4 weeks of different genotypes
of sugarcane had different tolerance to imazapyr. At the callus differentiation stage, the suitable imazapyr
concentration for ROC 22 and Yuetang 93-159 was 0.3 滋mol/L. At the shoot stage of differentiation for 4 weeks, the
suitable imazapyr concentration for ROC 22 was 0.5 滋mol/L, while was 1.0 滋mol/L for Yuetang 93-159. |
