　　为了研究植物生长调节剂对荔枝胚胎发育不同品种诱导焦核的效果，以大核品种‘黑叶’和部分焦核品种‘灵山香荔’为试验材料，研究不同浓度MH(maleic hydrazide)以及MH与2,4-D、BONA、CPPU等植物生长调节剂处理对焦核率及产量的影响。结果表明，以MH为基础的植物生长调节剂对荔枝胚胎发育不同品种均可诱导提高其焦核率，但MH浓度过高会对产量等性状产生副作用，适宜诱导荔枝焦核的MH浓度为600~800 mg/L。在不同植物生长调节剂组合试验中以MH+2,4-D处理诱导焦核效果最好，但植物生长调节剂对不同品种焦核诱导效率不同，‘灵山香荔’焦核诱导率可达89.77%，而‘黑叶’荔枝只有8.79%。

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’.
