摘　　要：以6a生春艳和特早红桃为试验材料,研究了不同质量浓度化学疏花疏果剂TMN-6对桃的疏花疏果效应和果实品质的影响。结果表明:TMN-6具有显著的疏花疏果效果,1mg/L TMN-6处理春艳和特早红桃的坐果率分别为29.41%和31.55%,可满足生产中对疏花疏果的要求。随着TMN-6质量浓度的提高,疏除效应明显增强,单果质量均显著高于对照,高质量浓度TMN-6处理后,坐果率减少,不能满足生产需求。采用TMN-6 1、2、4、6mg/L处理后,桃果可溶性固形物含量均显著高于对照,春艳桃可溶性固形物提高1.32～1.76个百分点,特早红提高0.99～1.52个百分点,而果实硬度与对照没有显著差异。A chemical thinning agent,TMN-6,was tested on six-year old Prunus persica Chunyan and Tezaohong trees with different concentration. The thinning effects of flower and fruit,and its influences on the fruit quality were also studied. The results showed that fruit setting rate of Chunyan and Tezaohong was 29.41% and 31.55 % when TMN-6 concention was I mg/L. With increasing concentration of TMN-6 agent,fruit setting rate decreased heavily. Howerer,average weight of single fruit was significantly higher than that of controls as fruit setting rate was too low. Soluble solid contents of fruit were 1.32--1.76 perle tage points （Chunyan） and 0.99--1.52 percentage points （Tezaohong） higher than those of the control, respectively. There was no significant differences on hardness of fruit between the control and TMN-6 treatment.
