结果表明：NMB培养基适合水稻成熟胚盾片愈伤组织诱导，MS培养基适合愈伤分化；500 mg/L谷氨酰胺或精氨酸有利于愈伤组织的形成；培养条件：愈伤组织诱导时温度25～28 ℃，暗培养，pH 5.8；分化时温度25～28 ℃，光照1 500～2 000 lx，12～14 h/d，pH 5.8；6-BA对继代过程中愈伤组织的生长有促进作用；潮霉素筛选的最佳浓度为50 mg/L。

On one hand, farmland is a kind of security for farmers in the primary stage of professional differentiation. On the other hand, it makes farmers reluctant to completely leave their farmland, which universalizes the diversity of farmers'professions and hinders further development of professional differentiation.

一方面，土地是职业分化初级阶段农民的保障手段；另一方面，它又使得农民不愿彻底脱离农业和农村，导致农民的兼业化，进而阻碍农民进一步的职业分化。

Only 10-day pretreatment of germinated seeds at 5℃ or 10℃ was enough to enhance the floral bud differentiation in the spring variety 'Duanye 13', whereas at least 20-day pretreatment was required for the promotion of floral bud differentiation in the winter variety 'Yidianhong'.

0.10一1.00mmol/l的5一azaC处理萝卜种子3一6d可以促进花芽分化和开花，这种促进效果在春性品种'短叶13'中更加明显。

Only 1O-day pretreatment of germinated seeds at 5℃ or 10℃ was enough to enhance the floral bud differentiation in the spring variety'Duanye 13', whereas at least 20-day pretreatment was required for the promotion of floral bud differentiation in the winter variety'Yidianhong'. Non-vernalized'Duanyi 13'plants flowered 70 days after transplanting in a warm (above 15℃) and long photoperiod (16h) growth condition, but non-vernalized 'Yidianhong'plants did not flower 90 days after transplanting in the same growth condition as'Duanye 13'.

处理温度越低和/和处理时间越长，对花芽分化和开花的促进作用越明显；春性品种'短叶13'的萌动种子在5℃和10℃条件下处理10d就能显著促进其花芽分化，而且即使未经低温处理，并给予15℃以上的生长温度和16h的长日照条件，植株也能在播种后70d内开花；但冬性品种'一点红'则需要在5℃或10℃下处理20d以上方能显著促进花芽分化，若不给予低温处理，即使给予16h的长光照条件，在播种后90d也不能开花。

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。

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 results showed that: a great quantity of compacted callus were induced on the MS medium supplemented with 6-BA and a large amounts of corms and young seedlings were differentiated on the differentiation medium, but plenty of loosened callus on the MS medium supplemented with 2,4-D and limited young seedlings on the differentiation medium.

结果表明：在附加6-BA的MS培养基上，外植体可诱导出大量的致密愈伤组织，而且致密愈伤组织在分化培养基中能分化产生大量圆球茎和幼苗；而在附加2，4-D的MS培养基中，外植体被诱导出疏松愈伤组织，在随后的分化培养基上只能产生数量有限的幼苗。

Methods Human monocyte cell line THP-1 was cultured and induced to macrophage by PMA treatment. The effect of 9-cisRA on the differentiation induced by PMA was studied. Cell morphology was observed by phase contrast microscope and the adhesion rate of THP-1 was detected by methyl thiazolyltetrazolium assay. The cell surface markers involved in differentiation of mono cyte/macmphage (CD11b, CD36) were analyzed by flow cytometry.

体外培养人单核细胞系THP-1，经佛波酯诱导分化为巨噬细胞，同时给予9-顺式维甲酸对佛波酯诱导分化进行干预，通过相差显微镜观察细胞形态，MTT比色法检测细胞贴壁率，流式细胞仪检测与单核／巨噬细胞分化有关的细胞表面标志物CD11b和CD36的表达。

Different ideas exist in the role of abscisci acid on flower bud differentiation bud differentiation of fruit trees.

但近年来的研究表明，果树的花芽分化不仅仅是营养问题，与其他的一些因素也密切相关。

Warden: That's a beautiful dog, but don't bring her again.

那是条漂亮的狗，但是不要再把她带来了。

You get up in the morning – no hangover!
