白及种子质量检验方法研究(1)
[摘要] 参照《农作物种子检验规程》对不同产地的白及种子进行质量测定,旨在为制定白及种子检验规程和质量分级标准提供依据。结果表明:白及种子采用过20目筛后进行净度分析;质量测定宜采用千粒法;水分测定采用高恒温(133±2)℃干燥法,烘干时间为3 h;发芽床选用滤纸床,发芽温度30 ℃较为适宜,种子萌发需要光照,发芽首末次计数时间为4~20 d;1% TTC溶液中40 ℃条件下,染色7 h测定生活力。

[Abstract]In order to provide a basis for establishing seed testing rules and seed quality standard of Bletilla striata, the seed quality of B.striata from different producing area was measured referring to the Rules for Agricultural Seed Testing(GB/T 3543-1995).The results showed that the seeds of B.striata passed through 20-mesh sieve for purity analysis.The weight of seeds was measured by 1000-seed method and the water content was measured at the higher temperature (133±2) ℃ for 3 hours.The seeds were cultured on the wet filter paper at 30 ℃ for 4-20 days in light for germination testing.The method of testing seed viability was that seeds were dipped into 1% TTC solution for 7 hours at temperature of 40 ℃. ......
