原位杂交分析结果表明:在幼苗期RA68主要在幼芽胚芽鞘的内外层细胞和幼叶原基的表层细胞中表达;转入生殖生长期后,在花序分生组织、枝梗原基顶端、花器官原基、大孢子囊和花粉粒中表达。

The excised leaf of Phalaenopsis RSW1 was used as explants, the effects of basic media, kinds and concentrations of 6-benzyl aminopurine (6-BA) and thidiazuron, dark culture phase, and leaf age on adventitious shoot regeneration from leaves of Phalaenopsis RSW1 were investigated.

以蝴蝶兰品系RSW1离体叶片为外植体,探讨了基本培养基、6-苄基腺嘌吟(6-BA)和噻重氮苯基脲、暗培养时间及叶片生育期对叶片不定芽发生的影响。

When the concentration of zinc nitrite is lower than 0.1 M,(002) is the prior face for zinc oxide. As the concentration raise, the other kinds of crystal face would appear. Among those data,(002) grows the best when the concentration of zinc nitrite is 0.06 M. We add lactic acid and citric acid respectively; there is an carboxyl group on the lactic acid and three carboxyl groups on the citric acid. The monodentate of lactic acid helps the growth of zinc oxide, compared to the tridentate of citric acid which can only produce zinc oxide film under very low concentration, but the growth of (002) face is not that stable as adding the lactic acid and zinc will electrodeposit to substrate.

实验中,当硝酸锌浓度低於0.1 M 时,氧化锌以(002)面为优选位相,当浓度提高,其他晶面将会出现,当硝酸锌为0.06 M,(002)晶面成长最佳,分别加入乳酸和柠檬酸,乳酸结构上有一羧基团而柠檬酸有三个羧基团,单芽基的乳酸有助於氧化锌成长,对照於三芽基的柠檬酸,则必须在极低的浓度下才能制备氧化锌薄膜,但(002)面成长却没有添加乳酸来的稳定而金属锌也会电沉积到基板上。
