【摘要】 用离体萌发培养法研究不同浓度蔗糖和聚乙二醇对金盏花花粉萌发的影响。结果表明:蔗糖和聚乙二醇在一定浓度范围内对花粉萌发具有促进作用,但超过一定浓度后则会抑制萌发;当蔗糖浓度为15 g/L,聚乙二醇浓度为16%时,金盏花花粉萌发率最高,达到54%。更多还原

【Abstract】 Using the vitro pollen germination method to study the effects of sucrose and polyethylene glycol concentration on pollen germination in marigold.The results showed that the pollen germination was promoted by the sucrose and polyethylene glycol concentration at certain values;Beyond values the pollen germination was inhibited.When the sucrose concentration was 15 g/L and polyethylene glycol was 16%,the pollen germination rate of marigold was the maximum,which reached 54%.更多还原
