Abstract: To develop a technique for improving the ratio of abortive seeds and quality, the normal seed cultivar ‘Heiye’ and partial abortive seed cultivar ‘Lingshan Xiangli’ were treated with different concentration of MH (maleic hydrazide) and some other plant growth regulators such as 2,4-D, BONA or CPPU to study the effect to the ratio of abortive seeds and yield. The results showed that the ratio of abortive seeds was increased with the increasing of MH concentration, but the yield was decreased simultaneously. The suitable concentration of MH was 600-800 mg/L in the induction of stenospermocarpy. 2,4-D and MH was the best treatment in inducing stenospermocarpy in this study. The reaction to the plant growth regulators was different between ‘Heiye’ and ‘Lingshan Xiangli’. The ratio of induced abortive seed in ‘Lingshan Xiangli’ was 89.77%, only was 8.79% in ‘Heiye’.
