OBJECTIVE
To find out the suitable time for collecting gallnuts. When Kaburgaia rhusicola parasailed on leaflets of Rhus potainii, the parts of the leaflets developed into gallnuts.
METHOD
The regulation of development and tannin amount during whole growing stage were studied.
RESULT
K. rhusicola lived in gallnuts for about 80 days. The gallnuts developed quickly during earlier stage and slowly during later stage. Gallnuts maturated from 12th, July to 30th, July, which had no relations with the size and the time for forming, but had relations with development at earlier stage. It developed quickly with earlier maturation and developed slowly with later maturation. Its tannin amount kept stable during the whole growing stage.
CONCLUSION
The best harvesting days are those shortly after 7th, July.
目的
探究五倍子的适宜采收时间。当红麸杨倍蚜在青麸杨小叶上致瘿后，小叶的相应部位便发育成五倍子。
方法
研究五倍子整个生长阶段的发育规律及单宁含量变化。
结果
红麸杨倍蚜在五倍子内生活约80天。五倍子前期发育快，后期发育慢。五倍子于7月12日至7月30日成熟，其成熟与五倍子大小及形成时间无关，而与前期发育有关，前期发育快则成熟早，前期发育慢则成熟晚。其单宁含量在整个生长阶段保持稳定。
结论
最佳采收时间为7月7日之后不久。
