摘　　要：研究了不同植物生长调节剂和叶面肥等外源物质对油茶采穗圃穗条生长的影响。结果表明：处理8（萘乙酸2000mg／L）和处理10（生命素400倍液）的穗条木质化程度显著高于对照；不同处理对油茶采穗圃穗条质量和产量的影响有显著差异，其中，处理1-处理3（喷施赤霉素500～1500mg／L）效果最好，其穗条的长度、粗度等质量指标均显著高于对照及其他处理，而且穗条节间距适度合理、利用率高，能有效提高穗条产量；除穗芽数与节问距呈负相关，且未达到显著水平外，其他指标间的相关性均达到显著或极显著水平，且均呈正相关。The effects of spraying different exogenous substances （plant growth regulators, foliage fertilizer） on the scion growth of Camellia oleifera in cutting orchard were observed. The results showed that the degree of scion lignification in treatment 8 （ spraying NAA 2000 mg/L） and treatment 10 （ spraying biogen 400 - times dilution） was significantly higher than that in control. The scion yield and quality of Camellia oleifera were significantly influenced by different treatments, and treatment 1 - 3 （ spraying GA3 500 - 1500 mg/L） acquired the best effects. In treatment 1 - 3, the quality indexes （ such as length, width） of the scion were significantly better than those in control and other treatments; the scion section spacing was reasonable too, thus the utilization rate and yield of the scion were higher. There were significantly positive correlations between any two indexes （except for the number of buds per scion, and scion section spacing）.
