以红杨桃成熟干种子为材料,萌发后剥离胚乳进行培养。结果表明,最佳诱导愈伤组织的培养基为MS+2,4-D　2mg/L+BA 0.2mg/L,诱导频率可达93.5％:将淡绿色致密的愈伤组织转至MS+ZT　3mg/L+NAA0.2mg/L的培养基上,经连续继代后,形成芽原基并发育成小植株,壮苗后取茎尖染色体显微观察,证明再生植株多为三倍体,其发生频率可达73.7％。 The mature seeds of red carambola were used as materials, and the endosperm was cultivated after germination. The results showed that the optimal medium for induction of callus was MS + 2,4-D 2 mg / L + BA 0.2 mg / L with the induction frequency of 93.5%. The pale green compact callus was transferred to MS + ZT 3mg / L + NAA0.2mg / L medium, after successive generations, the formation of bud primordium and the development of plantlets, seedlings shoots after taking microscopic observations stem cells, proved that the regenerated plants are mostly triploid, its Occurrence frequency up to 73.7%.
