Author: Duan Shu-ying, Chen Ye and Niu Mao-lin
Journal of Integrative Plant Biology 1986 28(5)
      
    This paper deals with some Middle Jurassic fossil plants from southern margin of the Eerduosi Basin. There are 36 species in 13 genus in this flora, i.e. Equisetum multi- dentatus Oishi, E. sp., Coniopteris hymenophylloides (Brongn.) Seward, C. bella Harris, C, burejensis (Zalessky) Seward, C. szeiana Choweet Yeh, C. tatungensis Sze, C. spp., Todites williamsoni (Brongn.) Seward, T. cf. williamsoni (Brongn.) Seward, Cladophle- bis asiatica Chow et Yeh, C. argutula (Heer) Fontaine, C. hsiehiana Sze, C. ( Gleichenites) takeyamae Oishi et Takahasi, C. cf. gracils Sze C. triangularis Oishi, C. grabauiana Pan C. cf punctata (Thoms) Chow et Yeh, C. spp., Baiera cf. concinna (Heer) Kawasaki, B. furcata (L. et H.) Braun, B. sp., Sphenobaiera longifolia (Pomel) Florin, Ginkgo obrutchewi Seward, G. sp., Phoenicopsis angustifolia Heer P. manchurica (Yo- koyama) Yabe, p. sp., Czekanowskia rigida Heer, C. sp., Pterphyllum sp., Elatocladus cf manchurica (Yokoyama) Yabe, E. sp., Podozamites lanceolatus (L. et. H.) Braun P. sp., Carpolithus sp. etc. The dominant groups of this flora are Filicopsida and Ginkgopsida. So it could be compared with the flora of Yanan Formation from inner Earduosi Basin and other floras from Northeast, Northwest and China, such as the floras of Dutung, Mentougon and Dongsheng etc. This flora is different from the Late Triassic flora and the Early Jurassic flora of North China. It belongs to the Coniopteris-Phoenicopsis flo- ra, which was assigned to Early-Middle Jurassic flora by Prof. Sze. But after studying, the authers believe that this flora should belong to Middle Jurassic rather than Early Jurassic. The climate was warm and damp in that time in North China.

Author: Jiang Hong
Journal of Integrative Plant Biology 1986 28(5)
      
    In this paper, the relationship among nature stand production of Picea asperata forest and ecology environment condition was studied. The nature stand average net- primary-production of P. asperata is 5626kg/ha/a, photo-energy utilize rate (P) is 1.63%, general production (Pg) is 18.85 kcal/m2/d. Spruce tree average net-primary- production (NPP) is 4676 kg/ha/a, P is 1.35%, and Pg is 15.57 kcal/m2/d. The close relationship among ecology environment condition, leaf area index (LAI) and NPP of stand and spruce tree was further studied. It was discovered that among NPP of stand and spruce tree and elevation, slope direction, and stand density are quadric curve correlation; among NPP of stand and spruce tree and soil thickness, LAI is linear correlation, these mathematical model was builded. The poly-factor regression relationship among the NPP of stand and spruce tree and LAI, gradient, elevation, stand density, nomal density, soft thickness, rate of stand grade I tree and slope direction was studied and statistics analysised. In different condition, the photoenerge utilize rate, general production and economy coefficient was further system studied from plant physiology-ecology.

Author: Chen Ru-min and Pan Rui-chi
Journal of Integrative Plant Biology 1986 28(5)
      
    When peanut plants (Arachis hypogaea L.) were treated with aqueous solution of Bo (2000 ppm) by spraying application, the cells of the assimilating tissue were enlarged and the thickness of the leaves were increased. B9 promoted the development of the chloroplast, so that the number of chloroplast, grana and the lamella were increased. As a result, the volume of the container of chlorophyll was enlarged. In addition, the chlorophyll content of file leaves also increased after B9 treatment, there fore the leaves turned dark green.

The Relationship Between Flowering Induction and the Changes of some Phosphatase Activities in Pharbitts nil
Author: Jin Shi-ping, Jin Shu-mei, Cao Guo-yi and Ren Xi-chou
Journal of Integrative Plant Biology 1986 28(5)
      
    This paper is dealing with the effects of the photoperiodic induction of flowering on the activities of four phosphatases (DNase, RNase, PDase, and 5-NDase) in Pharbitis nil. According to our experimental results, the patterns of changes of activity in these four phosphatases after short-day induction can be put into two cases. One is the case of DNase, which activities are decreased altar short-day treatment both in cotyledons and apices indicating that floral induction leads to dropping of DNA metabolism level Another is the case of the other three phosphatases with a very similar but quite different characteristic from that of DNase. In cotyledons, activities of the three phosphatases after induction are higher than those in the non-induced group. In apices, activities are also higher just after induction, and then drop gradually while activities in the non-induced group rise sharply so that both the two contrast curves show a form of X. These changes are evidently interrelated with RNA metabolic regulation in the apices after floral induction.

The Fine Structural Observation on the Development of Embryo and Endosperm in the Intergene- rfc Crosses of Fadish (Raphanus sativus L.) Cabbageo (Brassica oleracea L.)
Author: Qiu De-bo and D.J. Harberd
Journal of Integrative Plant Biology 1986 28(5)
      
    The present report deals with the structural abnormalities and abortion of the endosperm, and the related abnormal development of the embryos in the intergeneric crosses of radish (Raphanus sativus L.) with cabbage (Brassica oleracea L.) . The weak development of ER, the occurence of starch grains in chloroplasts, the curious distribution of chloroplasts around the nuclei, and the earlier formation of cellular endosperm are some primary structure abnormalities of endosperm and they may indicate the poor development, low metabolic activities, and precocious growth in the hybrid endosperm. The endosperm abortion, which starts from chalazal end endosperm, comprises the damage of both structure and function of ER membrane, and the disintegration of nuclei and organelles, or even death. The hybrid embryos degenerated very early in 2-cell stage or even zygote stage in case the endosperm Aborted early. In case of endosperm late-aborted, the hybrid embryos grew for quite a long period of time but become slow down as the endosperm showed abnormal development and started to abort. As the results, the embryos were smaller, the embryo propers and the suspensors showed no growth in step with one another, and the embryo cells appeared structural abnormalities, and finally degenerated and aborted.

The Polymorphy of Fronds and Chromosome Number of Ophioglossum petiolatum Hook
Author: Wang Zhong-ren
Journal of Integrative Plant Biology 1986 28(5)
      
    A morphological and cytological study of a population of Ophioglossum petiolatum Hook. from the vicinity of Kunming, Yunnan Province was carried out. The fronds of this species are very variabte in. either size or figure. The outlines of laminae of different plants vary from narrowly lanceolate to ovate or broadly ovate (length: breadth can be from 6:1 to 1:1). The apices of laminae range from taper-pointed to acute or blunt, and the bases of laminae from attenuate to cuneate or nearly truncate. In most cases, the spore mother cells of the species have 480 bivalents at pro-meta- phase I of meiosis. The spores produced after normal meiosis are seemingly available. It shows that the species is an octoploid and probably sexual In few plants, many univalents at metaphase I of meiosis have also been seen, but we have failed to count their exact chromosome numbers. However, it reveals that there is a second cytotype in the population. From the fact that O. petiolatum has the great morphological variability and approximately constant chromosome number in a single population, the ecological conditions may not be the main reason of morphological variations of the Species. The high level of polyploidy and probable inbreeding system, the subterranean gametophytes must be hard to outcross, may give it a great ability of genetic lead which increases the genetic heterogeneity. and morphological varibility of populations. The voucher specimens are deposited inthe Herbarium of our Institute (PE). I am grateful to Prof. W. M. Chu of Yunnan University for his helpful suggestion and discuss.

The Crossability of Triticum aestivum with Tetraploid Hordeum bulbosum
Author: Li Da-wei and Hu Qi-de
Journal of Integrative Plant Biology 1986 28(5)
      
    In order to study the crossability of wheat with H. bulbosum a series of wheat varieties from various sources and their F1 hybrids as well as tetraploid H. bulbosum from different countries were used as parents in this experiment. The main results of the experiment are showed as follows: 1. Twenty-one wheat varieties from Europe, West Asia, America, China, Australia etc. 11 countries and regions respectively as famele parents were crossed with four tetraploid H. bulbosum from Hungary, USSR, Canada and Germany. The seed set percentages in the intergeneric cross combinations ranged from 0.00% to 49.93%. Statistical analysis revealed that there were significant differences between the seed set percentages of wheat varieties. The crossability, with H. bulbosum might differed in different varieties of wheat from same country. 2. Various F1 hybrids resulting from 13 and 26 intervarietal cross combinations of wheat and their parents were crossed with H. bulbosum from Hungary and USSR respectively in different years. The mean seed set percentages of F1 hybrids, their male and female parents were 26.53%, 15.38%, 20.30% and 39.1%, 34.8%, 26.7% respectively. The results indicated that when some wheat varieties having poor-crossability with H. bulbosum were hybridized with other varieties especially with those varieties having high- crossability, the crossability of their F, hybrids probably had higher crossability than their parents having poor-crossability. Six F1 hybrids of wheat obtained from six com- binations of reciprocal crosses, in which the completely non-crossable varieties Hope, Xiao- Bai-Mang and high-crossable varieties Chinese Spring, Fortunate were used as male or female parent alternately, were crossed as female parents with H. bulbosum. All of 6 F1 hybrids were crossable and gave the percentage of seed set from 7.00% to 42.57%, although they ought to carry the dominant Kr genes responsible for non-crossability, which were passed on to F1 hybrids by non-crossable varieties, the parent Hope or Xiao-Bai- Mang. Clearly that is due to the gene interaction between female and male parents. Be- sides Kr loci in wheat, probably other genes can influence the crossability. 3. There were significant differences between clones of H. bulbosum in the crossa- bilities with wheat. In conclusion F1 hybrids of wheat have higher crossability with H. bulbosum than their parents having poor-crossability. This could be advantageous for exploitation of this technique. By selecting even more efficient clones of H. bulbosum and improving embryo culture techniques, the H. bulbosum technique will be used in wheat breeding program- mes probably.
