摘要: 以攸县油茶花药为外植体,研究了不同花粉发育时期、低温预处理时间及添加物对愈伤组织诱导的影响,同时分析了不同激素种类和比例对愈伤组织继代增殖的影响。结果表明:花粉四分体时期为油茶花药愈伤组织诱导的最佳时期;花药的低温预处理时间应在10 d以内;培养基添加物以AgNO3效果最优,诱导率最高为8102 %。继代增殖培养中6-BA与NAA配比有着较好的效果,其中最适增殖培养基配方为:MS+6-BA(200 mg/L)+NAA(005 mg/L)。

Abstract: The anther of Camellia yuhsiensis were selected as material. The effects of different culture conditions, including different developing period of pollen, time of low temperature pretreatment, and kinds of additives, on inducing callus were investigated. Then we further studied the influence of different plant growth regulators and ratio on callus proliferation. As a result, the best developing stage of pollen on inducing callus from oiltea anther is tetrad stage; the time of low temperature pretreatment should be below 10 days; and the best medium additives is AgNO3, with the high induction rate of 8102 %. In the culture of callus proliferation, the best combination is 6BA and NAA, and the best recipe of callus proliferation culture medium is MS+6BA(20 mg/L)+NAA(005 mg/L).
