In the present paper, the transformation of the larval central nervous system intothat of the adult, and the activity of cholinesterase in the brain of Philosamid cynthiaricini during metamorphosis are described. The central nervous system during the larval stage of Philosamia cynthia ricini con-sists of a cerebral ganglion, a suboesophageal ganglion, three thoracic ganglia and eightabdominal ganglia. The connectives between suboesophageal and the first thoracic gangliaare short and thick, have these two ganglia lie very close together. The three thoracicganglia and the 1st to 7th abdominal ganglia lie near the middle of the segments, withtheir interganglionic connectives almost equal in length. The 7th and 8th abdominal ganglia lie very close together; and the 8th abdominal ganglion actually lies within the7th abdominal segment. When the insect enters the prepual stage the connectives between the ganglia shortenconsiderably and the total length of the nerve cord is approximately reduced by one-third. A series of macro-anatomical changes in nerve cord and structural changes in brainoccur during the pupal stage. During metamorphosis, the brain gradually increase in sizewith the growth of the proto- deuto- and tritocerebrum. The connectives between thesuboesophageal and 1st thoracic ganglia lengthen. The suboesophageal ganglion assumesa more anterior position, eventually lying immediately ventral to, and actually fusing to-gether with the brain. The connectives between the 1st and 2nd thoracic ganglia some-what shorten and the mesothoracic ganglion moves anteriorly and close to the 1st thoracicganglion. The connectives between the 2nd and 3rd thoracic ganglia shorten, and de-generate gradually approaching the adult stage. The 1st and 2nd abdominal gangliamoves forward and fuse with the 3rd thoracic ganglion to form a large metathoracicganglion, while the 6th meets the contiguous 7th and 8th abdominal ganglia to form alarge compound last abdominal ganglion. In the result of shortening of the inter-ganglionic connectives and the fusion of ganglia, the whole nerve cord appears muchshorter. Only four abdominal ganglia remain during the adult stage. Concerning the inner structure of the brain a very great difference is noted betweenthe larva and the imago of this insect. The central body and the stalks of the mushroombodies appear and develop in size and differentiation during the larval stage and theoptic centers have begun their development as big imaginal discs. But the pons cere-bralis and the glomeruli olfactorii are not yet visible even in the fullgrown larva. Thestructures of the brain become more complicated during the metamorphosis. Regardingthe inner structure, the most noticeable differences are shown by the optic lobes. In thisregion, the imaginal discs give origin to the complicated optic centers of the adult. Thelamina ganglionaris, medulla externa and medulla interna are differentiated from theimaginal discs gradually during metamorphosis. The pons cerbralis, glomeruli olfactorii,corpus ventrale appear as the process of metamorphosis proceeds, and the interveningchiasmata of optic center and the mushroom body are also well organized in the 9th-daypupa. The activity of cholinesterase in the brain is lower at the beginning of prepupal stageand higher while appraoching adult emergence. The cholinesterase activity correspondedto 0.078 μm of acetyl choline hydrolyzed per mg of brain in half an hour at the prepupalstage, and to 0.485 μm at the end of pupal stage. The cholinesterase activity in brainincreases about 6-fold during metamorphosis. It is assumed that in the insect withoutdiapause like the Eri-silkworm the activity of cholinesterase in brain during the processof metamorphosis would increase gradually without any interruption as the time proceeds.This phenomenon is in contrast to that in the diapausing cecropia silkworm, in which aninterruption of cholinesterase activity occurs during diapause (van der Kloot 1955).

蓖麻蚕在变态期间,脑及腹神经索产生了一系列的变化。脑外部形态的显著变化是体积的增大,视叶的出现及脑与食管下神经节的愈合。由幼虫上簇开始至成虫羽化,共约19天。在此期间,脑的宽度由0.93毫米增至2.48毫米。视叶出现于幼虫上簇后第四天,即化蛹前一天;发育至化蛹后第七天,食管下神经节完全与脑愈合成环状。幼虫脑组织比较简单,视叶尚未显明分化,只是在脑的两侧前方有成团的神经细胞聚合而成的“原基”,成虫视叶组织即由这些原基分化而来。蕈体尚不完整,仅蕈体柄显明。化蛹后,视觉中枢的三个纤维区——神经节层,外髓和内髓——都已出现,中心体也清楚可见。化蛹后第九天,视叶的三个纤维区之间的交叉纤维显明地出现,其它各部分如中心体、脑桥体、腹体及嗅觉中枢都完全分化出来。脑构造的复杂化也明显表现在内部组织的分化上。 腹神经索的变化主要是缩短和神经节的合并。最显著的缩短阶段是在预蛹期,整条神经索由原来的43毫来缩短为29毫米。食管下神经节与脑愈合,腹部第一二神经节并入后胸神经节,第六、七、八神经节合并成一大型的复合神经节,这样便由原来的八个腹神经节减少了一半。胸部三个神经节则因菱形区的消失而互相靠拢。 从化蛹后第九天起至成虫...

The present paper observes and describes the differentiation of theprimary structure and the process of secondary growth occuring in the stemof Eucommia ulmoides. The stem apex of Eucommia ulmoides consists ofone-layered tunica and corpus. The differentiation of primary structure ofthe stem begins with the ground meristem which involves the cotex and thepith, while at the ring of procambium, the first primary vascular tissuesdifferentiate in three or four separate strands. At the successively laterstages of development as more and more of the strands may be differentia- ted in the vascular region. the primary vascular tissues have developedinto rings as a result. According to Esau, the primary vascular system ofthe stem of Eucommia ulmoides is a traces system, while at the same timethe structure of the stem nodes prossess the features of unilacunar gap andone trace. When the primary structure has completed its differentiation inthe stem of Eucommia ulmoides, the epidermis begins to be transformedphellogen, producing first periderm. At the same time, cell division takesplace in the vascular cambium as well, thus producing the secondary vascu-lar tissues. Before the growth season comes to a close, the secondarystructure has become the principal part of the stem of Eucommia ulmoides.

本文对杜仲茎内初生结构的分化和次生生长过程进行了观察描述。杜仲的茎端是由原套和原体组成,原套为一层细胞。茎的初生结构的分化开始于皮层和髓二部分基本分生组织,而原形成层环首先在3—4个分散的束内分化出初生维管组织,在以后的发育过程中,由于分化出更多的束,使初生维管组织联接成环状。参照Esau的观点,杜仲茎的初生维管系统应属于叶迹系统,而其节部结构的特征为单叶隙、单叶迹。在杜仲茎内初生结构分化完成时,其表皮即转变为木栓形成层,产生第一次周皮,此时,维管形成层也开始细胞分裂,产生次生维管组织,因此,在生长季结束时,茎内次生结构已成为主要部分。
