This paper reports the internal structure of root, stem, leaf and petiole in Brassica pekinensis, Brassica chinesis, Brassica oleracea var. botrytis, Brassica juncea var. crispifolia, Brassica napiformis and Raphanus sativus. The structural characteristics of various organs were compared. And it has been found that in the roots of these vegetables (except the storage root) there were aboundant sclerenchymatous cells between the vessels of secondary xylem.

This paper reports the internal structure of root, stem, leaf and petiole in Brassica pekinensis, Brassica chinesis, Brassica oleracea var. botrytis, Brassica juncea var. crispifolia, Brassica napiformis and Raphanus sativus. The structural characteristics of various organs were compared. And it has been found that in the roots of these vegetables (except the storage root) there were aboundant sclerenchymatous cells between the vessels of secondary xylem. The stem was similar to the root in this respect. The principle vascular boundls in petiole formed a U-shaped group, and each boundle consisted of several subsidiary boundles. Besides, there were scattered subsidiary boundles. The epidermal cells of leaves were unequal in size. The mechanical tissue on upper and lower epidermis of the main veins was poorly formed. If present, it was only one or two layers of collenchyma. while sclerenchyma was not found. The increase in thickness of root in garden radish and India mustard was resulted from groups of smaller cambiumous cells scattered among the parenchyma of the secondary xylem and from which the vascular tissues were differentiated, not from simple, usual development of secondary xylem. The structure of stem in cauliflower was different from other taxa in the same genus. Ths cause will be studied in furture.

本文以白菜,东北油菜、花椰菜、雪里红、芥菜、和水萝卜等六种十字花科蔬菜植物为对象,用石蜡切片法在光学显微镜下,从根、茎、叶柄及叶等营养器官进行观察研究,附图39幅。文中记载了各种植物营养器官的内部结构。比较了各器官在结构上的特点,指出上述各植物的根(贮藏根除外),在次生木质部导管之间存在大量厚壁状细胞,茎的次生木质部导管之间也有类似现象,叶柄中主要维管束排成U形,每一束由数小束组成,另外分散的小维管束同时存在,叶片上表皮细胞大小不等,主脉部份上下表皮处的机械组织很不发达,如有亦仅为1—2层厚角组织,未发现厚壁组织。文中对水萝卜、芥菜等根的增粗提出看法,认为不是简单的次生木质部特别发达,而是次生木质部的大型薄壁细胞中散生着成群的小型形成层状细胞,由它们分化成维管组织。花椰菜茎的结构与所观察的同属其它植物的茎不同,其原因有待于进一步研究。

用扫描电子显微镜对芸苔属19个种或变种,欧白芥属2个种的种皮表面形态进行了观察。根据种皮网纹的不同特点,分成7个类型。芸苔属中具有相同染色体数目的分类单位的种皮,具有相类似的网纹(芥蓝除外)。但在一些种间,尤其是在变种和品种间,只依靠种皮表面形态学特征进行鉴定是困难的或不可能的。双二倍体种的种皮表面结合了其二倍体祖先的种皮形态学特征。

When the explant of hypocotyl from cauliflower (Brassica oleracea var botrytis). was cultured on bassal medium with 2 ppm 2,4-D was able to dedifferentiation and produce callus; and that cultured with 5 ppm 6BA was able to differentiation and produce shoot buds. The peroxidase activity in the explant during the course of differentiation and dedifferentiation was determined with several substrates including three different phenolic compounds (caffeic acid, ferulic acid and guaiacol) and benzidine as H-donors....

When the explant of hypocotyl from cauliflower (Brassica oleracea var botrytis). was cultured on bassal medium with 2 ppm 2,4-D was able to dedifferentiation and produce callus; and that cultured with 5 ppm 6BA was able to differentiation and produce shoot buds. The peroxidase activity in the explant during the course of differentiation and dedifferentiation was determined with several substrates including three different phenolic compounds (caffeic acid, ferulic acid and guaiacol) and benzidine as H-donors. The results were illustrated in Fig. 3, 4 and 5. The peroxidase activity of tissues undergoing differentiation were greater than those undergoing dedifferentiation. The former rose rapidly, but the latter had only a low rise on the 4th day then the curve gradually changed into a plateau. During differentiation the peroxidase activity determined with caffeic acid was the greatest, followed by ferulic acid, guaiacol and benzidine. These results indicated that the peroxidase might be involved in the biosynthesis of lignin, since caffeic acid and ferulic acid is its precursors.

花椰菜下胚轴外植体在MS+6BA 5 ppm的培养基上能分化出芽,在MS+2,4-D2ppm的培养基上能脱分化而形成愈伤组织。用3种不同的酚类物质(咖啡酸、阿魏酸、愈创木酚及联苯胺)作氢供体发现分化过程中的过氧化物酶活性高于脱分化过程,其中以咖啡酸作氢供体显示的活性最高,阿魏酸及愈创木酚次之,而联苯胺最小。用聚丙烯酰胺凝胶电泳分离阴极向及阳极向过氧化物酶同工酶,在分化及脱分化培养过程中均不断出现新的酶带,前者有13条,后者为11条,两者的差别主要在阴极向酶带,在分化过程中多了两条酶带(C_1和C_3),同时C_2带活性也比脱分化的高。阳极向酶带也有差别,A_2和A_2两条酶带在分化过程中逐渐加强,但是在脱分化过程中却逐渐消失。反映了两个过程生理上的差别。
