作者：向巧萍傅立国中国科学院植物研究所

在扫描电镜下，比较观察了冷杉属全世界３６种２变种的叶角质层内表面的结构特征，根据叶角质层内表面胞间凸缘特征的显著差异，将冷杉属植物归为４类：（１）直且发达的单凸缘；（２）双凸缘；（３）不发达的单凸缘；（４）弯曲且发达... 详细信息

在扫描电镜下，比较观察了冷杉属全世界３６种２变种的叶角质层内表面的结构特征，根据叶角质层内表面胞间凸缘特征的显著差异，将冷杉属植物归为４类：（１）直且发达的单凸缘；（２）双凸缘；（３）不发达的单凸缘；（４）弯曲且发达的单凸缘。并发现这四种凸缘类型在冷杉属中的分布格局与该类植物的地理分布具有相关性。根据所观察的结果和前人的属下分类系统以及化石资料，认为北美西部是现代冷杉属植物的一个多样性中心。

Leaf cuticle analysis has long been a powerful tool for fossil plant identification,systematics,and palaeoclimatological *** recent decades the application of stomatal frequency data that are relied on precise calculation of stomata on plant fossil cuticles to reconstruct ancient atmospheric CO2 concentration made the preparation of cuticular membrane with suffi-cient size a critical technique in palaeoclimatological ***,for plants with originally thin and fragile cuticles,e.g.,most deciduous plants,conventional techniques sometimes fail to obtain cuticular membranes with sufficient size,or sometimes unable to recover *** has largely hampered the usage of fossil cuticle analysis in palaeobotanical and palaeoclimatological ***,we describe a new method using clear nail polish as a medium to "strengthen" the originally thin and fragile cuticles prior to maceration *** demonstrate the method by using middle Eocene Metasequoia fossils that were notorious for the difficulty of recovering large-sized clean cuticular membranes due to their thin and fragile ***,with well-documented and widely-distributed fossil records since the Late Cretaceous and with a living representative,***,as a comparative reference,has been widely used as a model genus for the study of evolution of plants,palaeoclimatological reconstruction,and plant adaptation to climate *** its deciduous habit produces thin cuticles and makes the preparation of clean cuticular membranes a tedious *** new method successfully allows us to recover its delicate cuticular membranes with sufficient sizes for SEM observation and stomatal frequency analysis.

Global Geology 2013年第2期16卷 59-67页

Some well-preserved conifer leafy shoots and female cones from the Lower Cretaceous Changcai Formation near Fudong of Helong, eastern Jilin, Northeast China are studied. Based on gross morphological and cuticular study, a new species, Elatides helongensis Sun et Zhao (sp. nov.) is described systematically. The new species is characterized by persistent, linear or slightly falcate leaves with obtusely acute apex, attached helically on the shoots. Female cones of the new species are terminal and oval, composed of persistent helically-arranged rhomboidal scales and erect seeds. One erect seed is growing on each scale. Leaf cuticles are hypostomatic. Monocylic stomata are ellipse, composed of 2 sunken guard cells and 4-8 subsidiary cells. Moreover, the cuticles of a young female cone of Pityostrobus yingchengensis Yang are described for the first time.

近年来，我县引进樟子松用于造林，但苗木成活和生长情况普遍不良。一、成活率低的主要原因1．用樟子松造林后幼树黄叶干枯死亡，通过对其生物生理学特性的词查和研究发现，导致这一现象的原因是樟子松树苗存在4个方面弱点：叶与茎生物量的比值高；叶纤嫩，木质化不够；针叶角质层不发达，气孔调节功能欠佳；苗木对全光适应性差。
