Abstract A melissopalynological study was carried out on 46 samples of Ziziphus lotus honey from Laghouat and Djelfa region (central Algeria). The number of pollen types identified per honey sample ranges between nine and 39 with a mean of 24. These correspond to 52 botanical families with 79 different pollen types in the whole samples. Asteraceae and Fabaceae families were present in all the samples where as Apiaceae, Brassicaceae and Nitrariaceae (Peganum harmala) were identified in more than 90%. Other plant families as Boraginaceae, Cistaceae, Myrtaceae, Oleaceae, Salicaceae or Urticaceae were identified in more than 50% of the samples but frequently as minor pollen. Ziziphus lotus pollen had a mean content of 68.9% (with a range of 45.3% to 93.4%). The secondary pollen types were Ononis natrix, Peganum harmala, Brassica napus, Echium and Olea europaea. Regarding the important pollen it is highlighted the presence Lotus t., Eucalyptus, Pimpinella anisum t., Trifolium t., Eryngium campestre t., Centaurea t., Galega officinalis t., Citrus or Scrophularia t. The sedra honeys of the studied region are characterised by their high content in pollen grains with a mean content of 188 403 grains/10 g. The presence of some pollen types in the pollen spectra of honeys such as Peganum harmala, Thapsia garganica, Launaea, Muscari comosum, Carthamus or Limonium bonduellei together several Asteraceae as Centaurea, Taraxacum, Carduus, Artemisia and Matricaria was proposed as geographical markers of this honey type.

阿尔及利亚产的 sedra 蜂蜜（Ziziphus lotus）的孢粉学特征

摘要 对来自 Laghouat 和 Djelfa 地区（阿尔及利亚中部）的 46 个 Ziziphus 莲蜂蜜样品进行了蜂花粉研究。每个蜂蜜样品鉴定的花粉类型数量在 9 到 39 之间，平均值为 24。这些对应于 52 个植物科，整个样品中有 79 种不同的花粉类型。所有样品中均存在菊科和豆科植物，其中伞形科、十字花科和白刺科（Peganumharmala）的鉴定率超过90%。在超过 50% 的样本中发现了其他植物科，如紫草科、Cistaceae、桃金娘科、木犀科、杨柳科或荨麻科，但通常是次要花粉。银杏花粉的平均含量为68.9%（范围为45.3%至93.4%）。次生花粉类型为 Ononis natrix、Peganumharmala、Brassica napus、Echium 和 Olea europaea。关于重要的花粉，强调存在莲花 t.、桉树、茴香 t.、三叶草 t.、Eryngium campestre t.、Centaurea t.、Galega officinalis t.、柑橘或玄参 t.。研究区域的 sedra 蜂蜜的特点是花粉粒含量高，平均含量为 188 403 粒/10 克。蜂蜜的花粉光谱中存在一些花粉类型，如 Peganumharmala、Thapsia garganica、Launaea、Muscari comosum、Carthamus 或 Limonium bonduellei 以及几种菊科如 Centaurea、蒲公英、Carduus、Artemisia 和 Matricaria 被提议作为这种蜂蜜的地理标记类型。Galega officinalis t., Citrus 或 Scrophularia t. 研究区域的 sedra 蜂蜜的特点是其花粉粒含量高，平均含量为 188 403 粒/10 克。蜂蜜的花粉光谱中存在一些花粉类型，如 Peganumharmala、Thapsia garganica、Launaea、Muscari comosum、Carthamus 或 Limonium bonduellei 以及几种菊科如 Centaurea、蒲公英、Carduus、Artemisia 和 Matricaria 被提议作为这种蜂蜜的地理标记类型。Galega officinalis t., Citrus 或 Scrophularia t. 研究区域的 sedra 蜂蜜的特点是花粉粒含量高，平均含量为 188 403 粒/10 克。蜂蜜的花粉光谱中存在一些花粉类型，如 Peganumharmala、Thapsia garganica、Launaea、Muscari comosum、Carthamus 或 Limonium bonduellei 以及几种菊科如 Centaurea、蒲公英、Carduus、Artemisia 和 Matricaria 被提议作为这种蜂蜜的地理标记类型。
