摘要: 为了探索不同肥料和不同质量浓度芸苔素内酯（BRs）在油茶Camellia oleifera优良无性系上的运用最佳效果，选择5年生长林4号长林18号和长林166号优良无性系油茶品种，采用L9（34）正交试验设计，对它们分别施生物有机肥、油茶专用肥及复合肥和叶面喷施0.067，0.033和0.020 mgL－1芸苔素内酯，然后测定各处理油茶叶片日光合速率和油茶茶果的各项指标，并对测得数据进行相应的分析和总结。结果表明：①净光合速率最高处理是长林166号品系，施复合肥和喷施0.067 mgL－1芸苔素内酯；②百粒质量最大处理是长林18号品系，施有机肥和喷施0.020 mgL－1芸苔素内酯；③出籽率最高处理是长林18号品系，施有机肥和喷施0.020 mgL－1芸苔素内酯；④出仁率最高处理是长林166号品系，施专用肥和喷施0.020 mgL－1芸苔素内酯；⑤出油率最高处理是长林4号品系，施专用肥和喷施0.033 mgL－1芸苔素内酯。表4参12Abstract: To explore the effects of photosynthesis and seed characteristics with fertilizer and brassinolides （BRs） application to Camellia oleifera，organic fertilizer，a special fertilizer of Camellia oleifera，and a compound fertilizer of N-P2O5-K204%，with a BRs spray in concentrations of 0.067，0.033，and 0.020 mgL－1 were applied to five-year-old Chang-lin 4，Chang-lin 18，and Chang-lin 166cultivars of C. oleifera using an L9（34） orthogonal test design. Then leaf photosynthetic rates and fruit characteristics were measured and analyzed using DPS 12.1 software. Results showed that（1） the highest photosynthetic rate was with Changlin 166using the compound fertilizer and 0.067 mgL－1 BRs；（2） the heaviest 100-seed weight and the highest seed extraction rate were found with Changlin 18 using the organic fertilizer and 0.020 mgL－1 BRs；（3） the highest benevolence extraction rate was withChanglin 18employing the specialty fertilizer with 0.020 mgL－1 BRs；and （4） the highest extraction oil rate was fromChanglin 4using the special fertilizer with 0.033 mgL－1 BRs.［Ch，4 tab. 12 ref.］
