摘　　要：以7a生杜鹃红山茶"红露珍"嫁接苗为试材,采用花粉离体培养法和联苯胺-过氧化氢法,研究测定了杜鹃红山茶不同月份的花粉活力和柱头可授性,并对其花期进行了观测。结果表明:杜鹃红山茶仅3月没有花开,8月开花量达到最大为24.2朵/株。12月当天散粉的花粉活力最好,花粉活力可达94.96%,柱头在未开花时,已具有可授性,不同月份柱头可授性持续时间不同,4、12月开花后48h柱头仍有可授性。Taking grafted seedlings of 7-year-old Camellia azalea ＇Hongluzhen＇ as test materials,the pollen viability and life-span of Camellia azalea was determined by pollen culture in vitro method,and its stigma receptivity was estimated by benzidine-H2O2 method,and the florescence were observed and studied in this paper. The results showed that Camellia azalea only no flower in March, the flowering maximum amount was 24. 2 flowers/plant in August. The experiment Of pollen vigor showed that the pollen vigor was the best in the early pollen dispersal period in December, could be amounted to 94. 96%, The stigma receptivity of Camellia azalea had receptivity before blooming,but there was：some difference at different months. The stigma receptivity still had strong receptivity within 48 hours after blooming in April and December.
