A detached garlic scape in long storage will eventually give rise to a whorl of freshy aerial cloves at its apex(Text fig.2).This can only be brought about at the expense of the stalk proper,where withering starts from the lower end and extends gradually up- ward until the whole stalk is completely exhausted.The material transfer involved must be mainly concerned with the redistribution and reultilization of cellular contents from the senescing stalk to the growing cloves.The present systematic investigation on the whole process is primarily based upon serial microscopic and electron-microscopic examination on conducting channels and withering parenchyma. Our previous investigations on garlic have shown that the exhaustive withdrawl of cellular contents from the senescing tissue is finally accomlished by intercellular move- ment of the partially disassembled protoplasm itself.The present result are essentially in agreement with such a general scheme.Light-and electron-micrographs that show nuclear material and other macro-molecular substances tranversing through the plasmo- desmata are rather common.The high resolving electron-micrographs have enabled us to detect the finer details in intercellular transport as given below: 1.Filamentous and fluffy material,somewhat similar in structure to P-protein in sieve tube,can be found in abundance in senescing parenchyma cells in which the demar- kations between protoplasmic components gradually become indistinct.The filamentous material is in transit through plasmodesmata between parenehyma cells and also between parenchyma and sieve tube(Plate Ⅱ,16,18). 2.Withdrawl of cellular contents from the deteriorating parenehyma may assume the form of vesicular transport through plasmodesmata(Plate Ⅰ 9,10,11).Some of the vesicles are simply filled with vacuolar sap; some fully packed with prefabricated ma- terial of macro-molecular structure;and some actually loaded with disassembled pro- toplasmic fragments. 3.Fully packed vesicles as well as disassembled protoplasmic components(includ- ing disintegrated nucleus,degenerated mitochondrion,etc.) may extrude into the intercel- lular spaces and may invade the vessel cavity (Plate Ⅱ,12,13,20; Plate Ⅲ,21,22,23, 24).The fine strueture of the moving protoplasm in the vessel is quite distinct from that of the residual deposits which may cause plugging in the same cavity(Plate Ⅲ, 25,26).

The ultrastructure of the secondary phloem of Rhus verniciflua Stokes was studies.In secondary phloem of the stem of Rhus verniciflua Stokes, sieve elements, companion cells, axial parenchyma cells, tannin cells and ray cells,Wnich are similar to those of general dicotyledens in ultrastructure,contain osmiophilic droplets.Some of them which are electron denser are similar to those of the secretory cells in property, and their distribution is the same as those of the latter. There is a tendency to transport the osmiophilic droplets outward from various cells through the plasmalemma and cell walls. It was suggested that, thus, various compositional elements of the secondary phloem in Rhus verniciflua Stokes furnish raw materials or precursors synthesizing secretions to the secretory cells of the canal besides normal nutritious supplies, and these raw materials or precursors are transported toward the secretory cells of the canal passing the plasmalemma and cell walls. Sieve area pores of mature sieve elements are lined with the thicker callose, and are plugged with the electron opaque P-protein.It is generally agreed that callose deposition and plugs of P-protein in the sieve area pores takes place in response to wounding.

本文叙述了漆树茎次生韧皮部各组成分子的超微结构。在漆树茎的次生韧皮部中,各个组成分子除了有与一般双子叶植物类似的超微结构外,筛管分子、伴胞、韧皮薄壁组织细胞,丹宁细胞和射线细胞中都含有嗜锇滴。其中电子密度较大的嗜锇滴与乳汁道分泌细胞中的相似,有相同的分布规律,并都有通过质膜和细胞壁向外运输的趋势。因此,我们认为,在漆树中,韧皮部的各个组成分子除了为乳汁道分泌细胞提供正常的营养物质外,同时也可能提供合成分泌物的原料或前体物质,而这些原料或前体物质是通过质膜和细胞壁向乳汁道分泌细胞转运的。此外,在成熟筛管分子的筛孔周围都衬有很厚的胼胝质,并为一些电子不透明的P—蛋白质所堵塞,这种现象可能是由于切割造成筛分子内部压力的消除和植物体产生损伤反应的结果。

The minor leaf vein of Populus deltoides Bartr. cv. 'Lux' (ex. I-69/55), and P. ×euramericana (Dode) Guinier cv. 'San Martino' (ex. I-72/58) has no A-type and B-type transfer cells, which exist in the herb dicotyledon. But some structures like compound plasmodesma and paramural body that vary morphologically with the development of the leaf can be produced by the companion cells and the phloem parechyma cells of the minor leaf vein.

The minor leaf vein of Populus deltoides Bartr. cv. 'Lux' (ex. I-69/55), and P. ×euramericana (Dode) Guinier cv. 'San Martino' (ex. I-72/58) has no A-type and B-type transfer cells, which exist in the herb dicotyledon. But some structures like compound plasmodesma and paramural body that vary morphologically with the development of the leaf can be produced by the companion cells and the phloem parechyma cells of the minor leaf vein. It's shown that their occurrence has something to do with the frequent local transport. The sieve tube members in the minor leaf vein are differentiated through the formation of the P-protein body, the function of the lysosome in the vacuome and the secretion of the dictyosome. In the two clones of the Aegeiros poplar, i.e., I-69 and I-72 there exist distinctions. It seems that the distinctions are related to the increment. Therefore, they require further research.

Populus delioides Bartr.ev.‘Lux’(ex.I-69/55),和P. ×euramericana(Dode) Guinier ev.‘San Martino’.(ex.I-72/58)无性系后代实生苗叶小脉不具有草本双子叶植物中的A型和B型传递细胞(transfer cell),但小脉伴胞和韧皮薄壁细胞的某些结构-复合胞间连丝和壁旁体(paramural body)的形态是随叶片发育而变化,表明它们的发生与局部频繁的运输有联系。小脉筛管分子的分化是通过 P-蛋白体(P-protein body)的形成和液泡系的溶酶体作用,并伴之以高尔基体的分泌作用。I-69和I-72无性系后代实生苗叶小脉的超微结构有区别,似与生长量有一定的相关性,值得深入研究。
