Two others were set up at the beijing institute of geology , ministry of geology , china , and the beijing institute of botany , chinese academy of sciences , in 1954 and 1959 respectively 1953年，中国的第一个孢粉实验室在中国科学院南京古生物研究所成立。 1954 1959年，原地质部地质研究所和中科院植物研究所也分别组建了孢粉学实验室。
The research during the prehistoric period is a base and difficult palynology which provides numerous evidences plays an important role and makes great contributions to the research on holocene environment changes 其中全新世以来史前时期是全新世环境变化研究的基础和难点。孢粉学在全球环境演变研究中提供了大量证据，发挥了重大作用，成果显著。
Subsequently , a large number of palynologists were trained , and a large number of palynology laboratories were begun throughout the country to meet the urgent need for extensive geological surveys and energy resource exploration 此后，为了满足国家地质调查和能源勘探工作的需要，大批人员接受培训成为了孢粉学家，他们在全国各地许多部门建立了孢粉学实验室或工作机构。
Palynology pollen of ephedra from china is studied . four types of pollen have been found in the genus , namely type a , b , c , and d , according to the number and structure of ridges and structural characters of grooves 4 、孢粉学补充了麻黄属中非常特化的种? ?斑子麻黄的孢粉资料，同时也对膜果麻黄( ephedraprzewalskii ) 、中麻黄、细子麻黄和木贼麻黄的孢粉重新进行了研究。
With a marked progress of more than 20 years , it became evident that palynologists should be united into a single federation , aiming to promote friendship among colleagues , to exchange information , to share recent advances both at home and abroad , and to generally raise the research level 二十多年内，中国的孢粉学研究人员迅速发展到了数百人。在此情况下，成立一个专门的学会组织以促进同行之间的交流和提高已经显得非常必要。
In the thesis , the systematic relationships of acorus together with araceae and typhales are discussed on the basis of features from micromorphology , anatomy , pollen morphology and floral development , with the aid of the data from their embryology , cytology , chemotaxonomy and molecular biology . firstly , it is found that there are many obvious differences between acorus and araceae 本文用形态学、解剖学、孢粉学及花器官发生等方法，并借助胚胎学、细胞学、植物化学及分子生物学等方面的资料，比较研究了菖蒲属( acorus )与天南星科( araceae )及香蒲目( typhales )的系统关系。
The present thesis is a comprehensive study on all species of ephedra from china based on morphological , anatomical , ontogenetic characters and fossil evidence with a focus on the taxonomy , the evolution of the female cones , and the ecology and distribution patterns of the genus 根据中国麻黄属植物分类及麻黄属起源和演化研究中存在的争论，本论文主要进行了分类学、形态学、微形态学、解剖学、形态发生学、孢粉学、古植物学、植物生态学和植物地理学等方面的研究。
According to researches on jurassic sporopollen features and physical characters of rocks in northwest area , it has been considered that the most obvious temperature - rise event , happened in the late stage of middle jurassic to the end of late jurassic time , results mainly from the global temperature - rise of the jurassic 通过对西北地区侏罗纪孢粉学特征的研究，并结合岩石的物理属性，认为中侏罗世晚期到晚侏罗世末存在一次最为明显的升温事件，其主要原因是由于侏罗纪全球性气温升高所导致。
The methods of classical classification , integrating the study on seed morphology and leave epidemics morphology , along with phytomorphology , phytotomy , phytoembryology , palynology , phytocytotaxonomy , phytochemistry and molecular systcmatics , were used to revise and complete the former taxonomic system 以经典植物分类学方法为基础，结合种子形态学和叶表皮形态学的实验研究，参考植物形态学、植物解剖学、植物胚胎学、孢粉学、植物细胞分类学、植物化学和分子系统学等方面的资料，对前人的五味子属分类系统进行修订和补充。
In the present dissertation , summarized and reviewed senior ' s study of lespedeza michx . , on the basis of this , studied plants of lespedeza michx . in inner mongolia by means of polynology and cladistics taxology , discussed part of controversial species with menthod of and peroxidase isoenzyme pattern analysis 本文在回顾和总结前人对胡枝子属lespedezamichx .植物研究的基础上，对在内蒙古分布的胡枝子属植物进行了支序分类学和孢粉学研究；还对部分有争议的种类做了过氧化物酶同工酶酶谱分析。
