【摘要】 采用蔗糖培养基离体培养法和 TTC 染色法对辣椒枣等7个主栽枣品种的花粉生活力进行测定,结果表明不同品种花粉生活力存在差异。对辣椒枣和临猗梨枣两个品种的花粉贮藏方法进行了研究,分别采用常温、常温干燥、低温、低温干燥、冷冻和冷冻干燥等6种方法贮藏, 发现不同方法对不同品种枣花粉的贮藏效果不同,在蕾黄期或初裂期采集花蕾;于低温干燥条件下贮藏,花粉生活力的保存效果较好。更多还原

【Abstract】 Pollen vitalities of 7 Chinese jujube cultivars were studied with two methods,i.e,in vitro culture with sucrose medium and TTC staining.The results showed that pollen vitalities were significantly different among cultivars.Storing methods such as normal-temperature,normal-temperature dehydration,low-temperature, low-temperature dehydration,freeze and freeze dehydration were studied with two cultivars.Different method showed various effects.Low-temperature dehydration was the most favorable method for preserving pollen vitalities.更多还原
