维管组织

A division of nonflowering plants characterized by rhizoids rather than true roots and having little or no organized vascular tissue and showing alternation of generations between gamete-bearing forms and spore-bearing forms; comprises true mosses and liverworts and hornworts.

无花植物的一个亚部，以假根而非真根为特点，有小的或没有维管组织，有结合体和孢子体的世代交替；由苔藓类组成。

It is continuous with the intrafascicular cambium.

在幼嫩的茎和根中，可看到原形成层进一步发育成束内形成层，后者的分裂活动产生了初生维管组织。

Is divided into two systems of the root-hypocotyl-cotyledon and the epicotyl, and there is only a simple linkage between the vascular tissues of stem and the hypocotyl without any transition.

本研究亦证实了可以将刺槐幼苗的外部形态描述为这两个系统，二者的维管组织只是简单的连接，不存在过渡。

SAM gradually becomes larger and appears moderate fasciation at last.

进入营养生长后，SAM的肋区细胞呈现出维管组织细胞的形态特征。

Cistanche seeds in the nearby of the haloxlon root can germinate haustorium, through which it invade Haloxlon's vascular bundle tissue and absorbs nutrition.

肉苁蓉种子在梭梭根系附近可萌发吸器，通过吸器侵入寄主维管组织吸收营养。

Periderm was composed by Cork, cork cambium, and phelloderm.

结果表明，格木根的次生结构由周皮和维管组织构成。

The secondary structure included periderm and secondary vascular tissue from the outer to inner, there were indistinct between spring wood and autumn, and the vessels were scattered in secondary xylem.

次生结构从外到内由周皮和次生维管组织组成，主要特征体现在年轮线不明显，次生木质部为散孔材。

Phloem Plant vascular tissue in which food is transported from areas where it is made to where it is needed or stored.

韧皮部：植物维管组织中将有机养料从一个区域输送至必需或贮存部位的结构。

Procambium The layer of cells that gives rise to the vascular tissue.

原形成层：形成维管组织的一层细胞。

The thickness of surface layer,thick angle tissue and vassular tissue were raised and the invasion and growth of Alternaria solani were hindered after applying K fertilizer,therefore the breaking－out time of the disease were delayed 3-4 d.Thus,the incidence of tomato early blight dropped.

32.0%和12%？22%。番茄茎角质层明显，厚角组织、维管组织厚度增加，占茎总横断面积比增大，细胞壁增厚，延缓茎发病时间3-4d，阻碍番茄链格孢菌的侵入和生长，使番茄早疫病发病率降低。
