In addition, the repair method can also be filled tree holes, stuffing is best to use small gravel and cement mixture to be compacted filler, filler to strengthen the connection with the xylem, inside the cave can be a number of electroplating nails nails, holes dug in on both sides 4 centimeters deep groove at the bottom of filler from the start, each 20-25 cm for the layer, using linoleum separated from each floor should be inclined slightly outward to facilitate drainage, the edge should not exceed xylem, so that cambium in the formation of callus on it.

另外，也可用填充法修补树洞，填充物最好用小石砾和水泥的混合物，填充物必须压实，为加强填料与木质部的连接，洞内可钉若干电镀铁钉，洞口内两侧挖4厘米深的凹槽，填充物从底部开始，每20厘米至25厘米为一层，用油毡隔开，每层都要向外略斜，以利排水，边缘应不超过木质部，使形成层能在它上面形成愈伤组织。

The investigation of laticifer differentiation has an important significance for developing chemistry-regulating technique in natural rubber production and for realizing the cambia differentiation mechanism.

乳管分化的研究对于发展天然橡胶生产的化学调控技术和认识维管形成层细胞的分化机制具有重要意义。

JA is a crucial signal molecule in inducing cambia to differentiate the secondary laticifer, and a local high level of JA in cooperating with other plant hormones, especially cytokinin, is prerequisite for the secondary laticifer differentiation.

研究表明，茉莉酸是诱导乳管分化的关键信号分子，局部高水平的茉莉酸是诱导维管形成层细胞分化次生乳管所必需的，同时需要其它激素的协同作用。

By using the "mechanical wounding"experimental system estabilished by us, and light- and electron microscopy, autoradiography and radioisotope technique, immuno-fluorescence localization, homologous clone and RACE technique, in situ mRNA hybridization and ELISA et al., we investigated the relationship between the transportation of exogenous JA and the secondary laticifer differentiation, the relationship between the producton and accumulation of endogenous JA and the laticifer differentiation from cambia, and the effect of appling exogenous jasmonates on the natural rubber production.

利用我们建立的机械伤害诱导乳管分化的实验系统，采用光学显微镜和电子显微镜技术、同位素示踪和放射自显影技术、免疫荧光定位技术、同源克隆和RACE技术、mRNA原位杂交和ELISA等技术，研究了外源茉莉酸在橡胶树体内的移动及其对维管形成层分化次生乳管的诱导效应、内源茉莉酸与乳管分化的关系以及茉莉酸类物质对天然橡胶产量的影响。

Rubber trees initiate laticifer differentiation in June and July while no laticifer differentiation occur during the periods from November to May under natural conditions on Hainan Island. Application of jasmonates induced laticifer formation in both immature and mature rubber trees. Tapping and/or pre-tapping enhanced the ability of vascular cambia to differentiate the secondary laticifers.

结果表明，在海南岛自然条件下，乳管分化开始于6~7月份，在11月～翌年的5月没有乳管分化；割胶包括正式割胶前的预割能显著提高橡胶树形成层分化乳管的能力，其影响的范围相当大；外施茉莉酸对未开割树和割胶树的乳管分化都有促进作用。

The Yangtze River, Wuhan Hanshui will naturally be divided into three towns, Wuhan, it is not easy to form centralized regional hot spots in real estate, real estate development to stay in the more primitive the development of point-axis, that is, transport, road-led regional development, such as Xu, development along the Avenue, and so on, without the formation of layer-style development, that is, ring expansion, a typical Beijing.

长江，武汉汉水自然会分为三个城镇，武汉，是不容易形成集中的地区热点，房地产，房地产开发留在更原始的发展，点轴，也就是说，运输，公路带动区域发展，如许，发展大道沿线等，没有形成层式发展，这就是环扩张，一个典型的北京。

The compounded resins thus obtained may be especially advantageously used in forming the interlayer of laminated safety glazings, such as vehicle windshields and architectural glazings.

如此获得的混合树脂可能特别有利地用来形成层压安全窗用玻璃（诸如车辆风挡和建筑物窗用玻璃）的中间层。

It also contains additional supporting tissue in the form of fibers and sclereids and some living parenchyma.

原生木质部和后生木质部组成初生木质部，是由顶端分生组织的原形成层发育而来。

The results show that,in the natural conditions,the intensity of sap flow of Populus populars was 0.088 L·cm -2 ·d -1 .The velocity of sap flow at different depths below the cambium showed the same temporal changes of Populus populars .

结果表明，在正常生长状态下，小美旱杨树干单位面积液流通量为 0 。0 88L·cm- 2· d- 1；形成层以下不同深度的树液流速具有相同的日变化趋势，在中午前后各深度流速值均达到最大，各深度流速差值亦达到最大。
