The Studies on Embryology in Fritillaria ussuriensis Maxim

The development of the anther wall follows Basic-type. The cytokinesis at the time of pollen mother cell meiosis conforms to successive type. The arrangement of the microspores in the tetrad is referred to isobilateral. The primary wall between the generative cell and the vegetative cell is callose. The callose wall is easily detected under the fluorescence microscope. The mature pollen grain is 2-celled type. The ovule is bitegminous, tenui-nucellar and anatropous. The development of the female gametophyte follows Fritillaria-type. The mature embryo sac. consists of the six cells including the seven nuclei. The fertilization is referred to the premitotic syngamy type. The fusion of the female and male nucleoli is not observed at the end of the fertilization. The division of the primary endosperm nucleus is earlier than that of the zygote. The development of the endosperm is referred to nuclear type. The division of the zygote is transverse of longitudinal, the development of the embryo conforms to Onagradtype. When the seed is mature, the embryo is at the proembryo stage without differentiation and the endosperm cells are not absorbed.

严重缺碘对体质及遗传性状影响的研究

对严重缺碘地区一个容貌特殊,身材较矮,智力低下的人群进行了体质特征及遗传性状的研究,并与国内有关本地区的调查资料进行了对照,提出人类体质特征和遗传性状除与人种、地理环境异同直接相关外,人体不可缺少的微量元素的摄入水平在一定程度上对其也产生影响。并且认为同一人种、民族居住同一地理位置所产生的体质差异应从水文、地质、生活方式、生活水平的不同进行综合分析。

The Development of Microsporangium and Microspore in Azolla

This paper presents a detailed report on the developmental progresses of the microsporangium and its microspores in Azolla filiculoides Lam., and shows the morphologicaI structures of the respective developmental stares with the aid of scanning electron photographs. The entire developmental progress may be divided into six stages: ( 1 ) The microspore mother cell initiating stage The microsporangium initial on the placenta of the sporocarp gave rise a sporogenous cell, and then divided four times to form sixteen microspore mother cells; (2) The meiotic stage–The microspore mother cells initiated meiosis inside their calIose walls. The radial and inner tangential walls of the tapetum were dissolved at the same time and followed by the formation of a sporoplasmodium; (3) The microspore shrinking Ⅰ–After the callose walls of tetrads was dissolved, those microspores that just released from the callose walls shrunk intensely and became spherical later again. The sporoderm of microspores was principally synthesized in this stage, and the volume of microspores became evidently increased. The microspores then gradually moved to the periphery of the sporoplasmodium; (4) The microspore shrinking Ⅱ-Each microspore formed a large vacuole and gave rise the second contraction. The periphery of the sporoplasmodium was gradually dissolved; (5) The massulae forming stage–The sporoplasmodium was dissolved successivelly, and the undissolvable granules and organelle membrane residues. became aggregated into the compartmental layer, and the microsporangium was divided into several large vesicles, each vesicle will form a massulae; (6) The microspore germinating stage–The ,natured microspores inside the massulae each gave rise an androgonial initial which divided two times to form four antherozoid mother cells and then gave rise the antherozoids. The relationships between the various morphological structures and their functions in the microsporangium developmental progress have breify discussed. In addition, our viewpoints have compared with those of previous investigations.
