Postharvest storage of tea seeds.

The recalcitrant, desiccation-sensitive seeds of tea remain viable for a period of one year when sealed in polyethylene bags and stored in a controlled environment at 4 deg C and 40-45% RH. Freshly harvested seeds contain 40% moisture and at this level the germination is around 100%. Seeds stored under normal ambient conditions lose moisture at a rapid rate and, at 23% moisture content, germination is reduced to 46%. The critical moisture level in seeds for maintaining viability was 30%, where the germination was 86%. Surface sterilization with 0.1% HgCl2 before cold storage enabled viability to be retained for a longer period. Microbial contaminants in seeds punctured by seed bugs [Poecilocoris latus] were difficult to control either by surface sterilization or by cold storage.
