Sporo-pollen assemblages,with proteaceous pollen and Normapolles,are obtained from the boring cores and some black clay deposits in the vicinity of Er-Lian-Hao-Te city of northern Nei Monggol(Inner-Mongolia).Seventy species are reported,in which Proteacidites microverrucatus,Beaupreaidites striatus,Triatriapollenites echina- tus and Echitriporites magnus,are described as new. These assemblages are conspicuously poor in pteridophytes and rich in gymnos- perms of the families and genera:Pinaceae,Pod ocarpaceae...

Sporo-pollen assemblages,with proteaceous pollen and Normapolles,are obtained from the boring cores and some black clay deposits in the vicinity of Er-Lian-Hao-Te city of northern Nei Monggol(Inner-Mongolia).Seventy species are reported,in which Proteacidites microverrucatus,Beaupreaidites striatus,Triatriapollenites echina- tus and Echitriporites magnus,are described as new. These assemblages are conspicuously poor in pteridophytes and rich in gymnos- perms of the families and genera:Pinaceae,Pod ocarpaceae and Ephedraceae,especial- ly Cedripites,Podocarpidit,es and Ephedripites.Angiosperms are quite diverse in types,besides the proteaceous pollen and Normapolles(Altantopollis,Pseudoatlantopol- lis cf.simulatus,Choanopollenites),Momipites coryloides,Momipites tenuipolus,Paraal- mipollenites confusus,Platycarga,Ulmoideipites tricostatus,U.krempii,Cranwellia cf umseyensis,Disyllabipollis labeosus,Rhoipites,Lonicerapollis gallwitzi,L.scabratus etc.These pollen assemblages are assigned to the families Myricaceae,Juglandaceae, Betulaceae,Fagaceae,Ulmaceae,Proteaceae,Lorathaceae,Anacordiaceae,Symplocaceae, Aquifoliaceae and others.Most of them are tropical and subtropical.This indicates that a warm-temperate and dry climate was prevailing at that time. Based upon the nature of sporo-pollen assemblages,the age of the black clay de- posits is assigned to Maastrichtian. Maastrichtian pollen flora of northern Nei Monggol is associated with Siberian- Pacific Province by the abundance of proteaceous pollen on one side and with the Euro-American Province by the presence of Normapolles on the other.

The plantlets were produced from firm white callus of young stemcuts of Populus diversifolia Schrenk, which initiated on the Murashige and Skoog medium or B5-medium (Gamborg, 1968), containing 0.5-1.0 mg/liter BAP (6-Benzylaminopurine) and 2 mg/liter 2.4 D (2.4-Dichlorophenoxyacetic acid) or 2 mg/liter NAA (2-Naphthlyacetic acid) and subcultured monthly three or four times. When the callus was subcultured to MS- or B5-medium without attxin, but containing 0.5-1 mg/liter BAP, multiple bushed buds developed on the surface of callus with light green colour. The buds with 1-2 cm length were transplanted into MS- medium containing 2 mg/liter NAA for root formation and plantlet were produced 4-5 weeks after transplantation. The whole procedure was lasted 3-4 months.

胡杨是沙漠和盐碱地上造林中比较理想的树种,但胡杨插枝难于生根,而实生苗生长缓慢,且在苗期易感染锈病,难于进行大量而快速的繁殖。我们试验的目的是利用组织培养法探索快速繁殖胡杨的途径。国内外已有一些关于杨属植物通过组织培养获得小植株的报道,但直到目前尚未见到用胡杨茎脱分化产生的愈伤组织诱导获得小植株的报道。本文报道我们用胡杨当年枝条离体培养的愈伤组织诱导产生小植株的试验结果。

Radioramus gen. nov. described in this paper is a new genus belonging to Coleochaeta-ceae a family of the filamentois green algae, and R. halophilus sp. nov. is a new species of this genus.The algae has thallus of branched filaments composed of two parts quite different in morphology. In one part all the filaments are prostrate with the branches laterally opposel to form a layer of pseudoparenchyma that is one cell in thickness. The other part consists of erect filaments, each with a thicker primary branch and...

Radioramus gen. nov. described in this paper is a new genus belonging to Coleochaeta-ceae a family of the filamentois green algae, and R. halophilus sp. nov. is a new species of this genus.The algae has thallus of branched filaments composed of two parts quite different in morphology. In one part all the filaments are prostrate with the branches laterally opposel to form a layer of pseudoparenchyma that is one cell in thickness. The other part consists of erect filaments, each with a thicker primary branch and a thinner branch.The cells of the thallus are uninucleate with a single laminate chloroplast that partially encircles the protoplast. Some of the cells in erect filaments are developed in thick-walled akinetes and some apical cells bear a single, long, unbranched seta whose base is ensheathed by a cylinder of gelatinous material. There may be one pyrenoid or more within the chloro-plast.The asexual reproduction of this algae is performed by means of zoospores, which are developed only in the apical cells.The specimens were collected in a water-logged depression of alkaline soil in the southern suburb of the city of Baotou, Inner Monogolia Autonomous Region which lies to the north of a section of the Yellow River (Huanghe River) dike system in Oct. 10, 1963. The type specimens (Typus HBI, MG 14-15) are preserved in 4% qormalin in the Algae Herbarium, the Institute of Hydrobiology, Chinese Academy of Science.

于1963年在内蒙古自治区包头市南,黄河堤坝北岸盐碱地积水洼中采得两号标本,经光镜观察表明,该新植物为鞘毛藻科一新属——辐枝藻属。辐枝藻为分枝丝状体,由匍匐部分和直立部分组成;匍匐枝彼此贴靠形成单层细胞厚的假薄壁组织;直立枝具粗壮的主轴和细的小枝;部分小枝末端细胞具一条长的鞘毛;每个细胞具一个周生、片状的色素体,蛋白核一至多个,具一个细胞核。该藻以动孢子营无性生殖,动孢子囊位于枝或小枝顶端。此新属仅一新种,为嗜盐辐枝藻。模式标本保存于中国科学院水生生物研究所。
