三七及屏边三七花粉不同贮藏条件生活力测定

Determination of Pollen Viability of Panax Notoginseng and Panax Stipuleanatus on Different Store Conditions

采用MTT染色法测定栽培三七及屏边三七在不同贮藏条件下花粉生活力维持时间,结果表明,三七花粉在冰冻条件下,花粉从有活力至活力完全丧失约80 d,保鲜条件下二年生三七花粉活力维持时间约45 d,三年生三七花粉活力维持时间约60 d。屏边三七花粉在保鲜条件下从有活力至活力完全丧失约60 d,而冰冻条件下仅为35 d。

The paper determines pollen viability of Panax notoginseng and Panax Stipuleanatus on Different store conditions by MMT staining method and discovers that pollen viability lasts about 80 days under the freezing condition, two-year-old pollen 45 days, and three-year-old pollen 60 days. Pollen viability of Panax Stipuleanatus lasts 60 days under the fresh-keeping condition, but only 35 days under the freezing condition.
