Peroxidase settling process was the optimum staining for the fast determination of Alnus formosana pollen viability.

过氧化物酶沉淀法是快速测定台湾桤木花粉生活力的适宜方法。

Stamens 1 or 2 × as many as sepals; filaments short, slender; anthers basifixed, mostly oblong or linear, 4-loculed, dehiscing by slits, antisepalous anthers sometimes somewhat longer than antipetalous ones; pollen grains shedding at 3-celled stage. Ovary inferior, 1(or 2)- or 4-celled, septa solid or practically absent (present only at base and apex of ovary); styles as many as sepals, alternisepalous, free, mostly short, grading into globose or subulate stigmas, spreading in fruit; stigmatic papillae hairlike; ovules as many as styles, rarely 1, apical, pendulous, anatropous.

雄蕊1或2 *同数萼片；花丝短，纤细；花药基着，通常长圆形或者线形，4室，纵向开裂，对萼花药稍比对瓣花药长；花粉粒在3室的阶段散落子房下位，1(或者2)或4室，隔膜实心或几乎无(只在基部和子房先端存在)；花柱和萼片同数，与萼片互生，离生，柱头乳突毛发状；胚珠与花柱同数，很少1，顶生，倒生。

The 78 kD and 40 kD bands were the major allergens of Amaranthus spinosus.

刺苋花粉78 kD和40 kD的变应原为主要特异性变应原。

Western blot assay indicated that the crude extract reacted with serum obtained from sixteen Amaranthus spinosus pollen-allergic subjects and contained four allergen bands in total, and that the 78 kD and 40 kD bands were the major allergenic components.

Western blotting结果表明，16份刺苋花粉过敏患者的血清全部呈阳性反应，浸出液中共有4条致敏条带，其中主要致敏蛋白的分子量是78 kD和40 kD。

The parents of Morinoipollenizes might have evolved from anemophilous to entomophilous pollination, from bush to perennial herb and from living in lower mountains or hills to living in high mountains.

它们是我国晚白至世的重要化石，对我国微古植物地理分区，具有重要作用(周山富等，1987)。王大宁、席以珍提供现代花粉照片，在此致以谢意。一、江汉粉、刺参

Important spore and angiospermae pollen fossils such as Asterisporites,Cranwellia,Xinjiangpollis,Beaupreaidites and Quantonenpollenites have been obtained from the the upper part of the Member 4 of Quantou formation. They are Late Cretaceous in age. The reasonable geologic time of the upper Quantou formation may be later than Cenomanian deduced by the age of the upwards spore and angiospermae pollen fossils and the palynological assemblages.

根据泉四段顶部地层中一些具有重要时代意义的孢子和被子植物花粉化石Asterisporites，Cranwellia，Xinjiangpollis，Beaupreaidites，Quantonenpollenites等在世界各地的地史分布及与已知孢粉组合的比较，得出泉头组上部的地质时代可能不早于塞诺曼期。

The major scientific achievements of this study are as follows:1.Important angiospermae pollen fossils such as Quantonenpollis,Cranwellia,Scollardia, Lythraites,Xinjiangpollis,Gothanipollis,Triporopollenites and angiospermae fossils as Platanus septentrionalis,Trapa angulata have been obtained from the Quantou Formation. They are Late Cretaceous in age.

获得的主要认识如下：1、泉头组产有晚白垩世重要的被子植物花粉化石Quantonenpollis，Cranwellia，Scollardia，Lythraites，Xinjiangpollis，Gothanipollis，Triporopollenites等和晚白垩世被子植物化石Platanus septentrionalis，Trapa angulata等。

Combining with the result of emasculation, bagging, artificial pollination and pollinating observation, it was concluded that L.pincina should be anthophilous flower plant under natural condition.

结合套袋实验和传粉观察结果认为：在自然条件下，滇丁香为虫媒花植物，其中针型花和线型花所接受的亲和性花粉分别为异株同型花和异型花提供。

"Bee:any of several winged, hairy-bodied, usually stinging insects of the superfamily apoidea in the order Hymenoptera, including both solitary and social species and characterized by suck ing and chewing mouthparts for gathering nectar and pollen."

蜜蜂：蜜蜂总科中膜翅目的一种带翅、体附茸毛、通常螫刺的昆虫，包括独居类和群居类。它们的特点为可以用嚼吸口器采取花蜜和花粉。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
