本试验选用菰(Zizania)作供体,栽培水稻品种为受体,采用花粉管通道法进行DNA转移的研究。结果表明:受体水稻第二代在抽穗期、株高、穗长、千粒重、芒性、色素和子粒蛋白质含量等性状上产生了明显的变异,过氧化物酶同功酶的酶带数比对照增多,酶活性比对照增强,表明外源DNA已转入水稻起作用。 In this study, Zizania was used as a donor and rice cultivars were used as recipients. DNA transfer was studied by pollen tube pathway. The results showed that the second generation of recipient rice had obvious variation on heading date, plant height, spike length, 1000-grain weight, malleability, pigment and grain protein content. The number of peroxidase isozymes Control increased, enzyme activity increased compared with the control, indicating that exogenous DNA has been transferred to rice.
