Information in the literature and unpublished results of the authors on Dobinea were used to determine the kind [class(es)] of seed (true seed + endocarp) dormancy and of non-dormancy of genera in all five tribes of Anacardiaceae, and the results were examined in relation to the taxonomic position and endocarp anatomy within the family. Reports of both seed germination and endocarp anatomy were found for 15 genera in tribe Spondiadeae, 6 in tribe Anacardieae, 30 in tribe Rhoeae, 3 in tribe Semecarpeae and 1 in tribe Dobineeae. In Spondiadeae (Spondias-type endocarp), Anacardieae, Semecarpeae and Dobineeae (Anacardium-type endocarp), seeds are either non-dormant (ND) or have physiological dormancy (PD). In Rhoeae (Anacardium-type Rhoeae Groups A, B, C and D endocarps), on the other hand, seeds are ND or have physical dormancy (PY), PD or PY + PD. PY/PY + PD in this tribe seems to be restricted (or nearly so) to Rhus s.s. and closely related genera (e.g. Cotinus, Malosma and Toxicodendron) with an Anacardium-type Rhoeae Group A endocarp. However, seeds of other genera (e.g. Astronium and Schinus) with this type of endocarp and those with Rhoeae Group B (e.g. Pistacia), Group C (e.g. Pentaspadon) and Group D (e.g. Heeria) endocarps are either ND or have PD. The fossil fruit record strongly suggests that present-day relationships between diaspore dormancy (or non-dormancy), endocarp structure and taxonomic position within Anacardiaceae extend back to at least the Palaeogene.

漆树科种子(真种子加内果皮)休眠与科下分类学和内果皮解剖学的关系

文献中的信息和作者未发表的结果多比尼亚用于确定漆树科所有五个部落中种子(真种子 + 内果皮)休眠和非休眠属的种类 [类别],并根据分类位置和内果皮解剖学检查结果家庭。有种子萌发和内果皮解剖学报道的有Spondiadeae族15个属、Anacardieae族6个属、Rhoeae族30个属、Semecarpeae族3个属和Dobineeae族1个属。在Spondiadeae(斯彭迪亚斯型内果皮)、漆树科、番荔枝科和绣球花科(漆树型内果皮),种子要么是非休眠(ND),要么具有生理休眠(PD)。在梨科植物(漆树- 型 Rhoeae 组 A、B、C 和 D 内果皮),另一方面,种子是 ND 或具有物理休眠(PY)、PD 或 PY + PD。这个部落中的 PY/PY + PD 似乎仅限于(或几乎如此)漆树. 和密切相关的属(例如黄栌属,马洛斯马毒木属) 与漆树-型 Rhoeae A 组内果皮。然而,其他属的种子(例如天文斯基努斯) 与这种类型的内果皮和具有 Rhoeae Group B 的那些(例如黄连木), C组(例如五爪龙) 和 D 组(例如海里a) 内果皮是 ND 或 PD。水果化石记录有力地表明,现今水铝石休眠(或非休眠)、内果皮结构和漆树科内的分类位置之间的关系至少可以追溯到古近纪。
