茶籽贮藏特性的研究

王立　周明德　曾勤

摘要　对刚采收下的茶籽，进行不同方法的脱水干燥和低温、超低温(－196 ℃)处理后，用沙播法测定其发芽率。结果表明，在短期内，茶籽即使脱水至2.3%的含水率，仍能保持70%的发芽率。将茶籽干燥至8%～10％含水率，在－196　℃液氮中贮藏2个月，其发芽率没有变化，表明利用超低温长期保存茶籽有望得到解决。从本试验脱水干燥和冷冻损伤处理结果看，茶籽的贮藏特性应归属于正常型种子。

Abstract The newly plucked tea seeds were treated with various desiccation methods，low temperature and ultra low temperature （－196℃），and then，the germination of the seeds was tested by sand culture method．Results showed that tea seeds had 70％ germination rate even when the water content was lowered to 2.3％．No damage was observed to the germination of tea seeds when the water content in tea seeds were lowered to 8％—10％ and kept for 2 months under －196℃．According to this investigation，tea seeds should not be classified into the recalcitrant type，as most botanists believed．Tea seeds should be classified as normal type seeds．This result will direct us to further investigate the storage technique of tea seeds．The problem for long-term storage of tea seeds will be solved．
